Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a performance assessment and management system for enterprise workers by integrating three modules of system management, performance assessment and safety authentication, wherein the system architecture is shown in figure 1 and comprises a system management module, a performance assessment module and a safety authentication module, and the specific implementation mode is as follows:

first, system management module

The system management module is used for providing all-round organization architecture management, employee management, system user, role and authority management for managers and comprises an organization architecture management module, an employee management module, a system user, a role and authority management module.

(1) Organization architecture management module

The organization architecture management module is used for informatization access and management of enterprise administrative organization architectures, forms an organization architecture tree by inputting the enterprise administrative organization architectures step by step, provides functions of adding, deleting, modifying, condition query and the like of the organization architectures, and realizes informatization display and management of the enterprise organization architectures.

When the organizational data management of an enterprise is carried out, the tree structure of the kind mostly adopts the multi-branch tree storage, but the multi-branch tree structure has the following problems in the concrete business implementation: the traversal of the tree is recursive traversal, and each recursion needs to open up a corresponding memory space (recursive stack), so that certain memory consumption exists. In the system, the relationship of the parent node and the child node in the tree is expressed into a level field in a table, the field records the path from the root node to the node in the architectural tree, for example, the organization id of a certain top level organization is ' 001 ', the level field is ' 001- ', the top level organization has a child organization with the organization id of ' 002 ', the level field is ' 001-. Therefore, when searching for the descendant nodes of a certain group of organization, all the descendant nodes of the organization can be quickly searched out only by using the indexes on the column level and then using SQL 'like XX%' matching, so that multiple recursions of the tree structure when searching for the descendant nodes are avoided, and particularly, when the organization tree structure is complex, the searching efficiency is greatly improved.

(2) Staff management module

The employee management module is used for information input and management of employee information, functions of adding, deleting, modifying, inquiring conditions and the like of the employees and personal information of the employees are provided, two input modes of manual input of the employee information and intelligent batch import are supported, and personalized display and management are efficiently and reliably carried out on the employee information.

As shown in fig. 2, the system provides a worker information import excel template file, logs in the system to download the template and fill in worker information according to requirements, and uploads the template to the system for batch import, wherein if the system identifies that the worker information in a certain column of the excel file is abnormal (for example, the organization information to which the worker belongs has a department which is not entered in the system), the batch import abnormality is thrown out, and the position of abnormal data in an excel form is fed back to a user, so that what kind of error occurs in the information in a certain row and a certain column of the excel. In addition, the batch import transaction adopts a non-rollback strategy, the employee information before the abnormal data is successfully imported, and the data after the abnormal data is failed to be imported. Therefore, when the batch import of the employee information with large data volume is carried out, the large affair rollback caused by the abnormal row is avoided, and the batch import of the data of the latter half is carried out again only from the abnormal row.

(3) System user, role and authority management module

The system user, role and authority management module provides functions of adding, deleting, modifying, condition inquiring and the like for the system user, the role and the authority. In addition, by establishing a user-role-authority three-layer model, fine-grained system authority control is realized.

In the system, users with different roles have access rights to different levels of system services, based on the idea of AOP, through designing a rights control section (Aspect), writing related logic codes for rights judgment in the section, then appointing an @ Around notification type in the section and using an @ association cut point indicator to limit and match a connection point (join point) with appointed annotation, and finally adding the appointed annotation on a service code interface method corresponding to the rights as a connection point, when the system requests to execute a corresponding service method, the flow is as shown in figure 3, firstly judging whether the role owned by the user has the calling rights of the service method in the section, and if so, normally executing the service method. If not, the service is refused, and a notice that the service interface is not called is returned to the client. The scheme realizes the isolation of the authority control service logic from other part of service logic, reduces the coupling degree between each part of service logic and improves the reusability of programs.

Second, performance assessment module

The performance assessment module is used for providing assessment project management and assessment data integrated display service for managers and providing assessment and assessment data integrated display service for daily work and various project work for workers, and comprises an assessment setting module, an assessment to-be-handled module and a data billboard module.

(1) Examination setting module

The assessment setting module is used for providing assessment items and assessment time management for managers, and comprises two sub-modules of assessment item management and assessment time management, wherein the assessment item management sub-function module provides functions of addition, deletion, modification, condition query and the like of assessment items and assessment key points, and supports flexible weight distribution of the assessment key points. The assessment time management sub-function module realizes the periodic initialization function of assessment data and the disaster tolerance strategy of assessment service by carrying out database persistence on assessment intervals and assessment time; meanwhile, a method for dynamically adjusting the assessment work interval and the assessment open time period is provided, and the method can be well adapted to the characteristics of assessment work period and variable frequency.

The management of assessment items and assessment key points, the initialization of assessment data and the dynamic adjustment of assessment intervals and assessment time periods are specifically introduced as follows:

(a) the assessment items and the assessment points are in one-to-many relationship, one assessment item corresponds to one to a plurality of assessment points, and meanwhile, each assessment point corresponds to one score interval. On the basis, the functions of increasing, deleting, modifying and checking the assessment points and assessment items are realized, as shown in fig. 4 and 5.

(b) The initialization of the assessment data is realized by using a timing task, as shown in fig. 6, when the system is started, the assessment open time and the assessment interval in the database are read, the initialization task of the assessment data is executed at each assessment open time, whether the assessment needs to generate the initial data of the employee is judged according to the time of the employee entering the job and leaving the job and the assessment interval, if the interval where the time of the employee entering the job and leaving the job is located and the assessment interval have an intersection, the initial (unscored) assessment data is inserted into the assessment interval, and if the interval where the time of the employee entering the job and leaving the assessment interval have no intersection, the initial assessment data does not need to be inserted into the assessment interval. In addition, the examination interval and the examination time period in the database are periodically delayed by setting the timing task (namely, after one examination is finished, the examination interval and the examination actual period are set as the next examination), so that the automatic management of the examination interval and the examination time period is realized.

(c) The dynamic adjustment of the assessment interval and the assessment time period needs to realize the updating of a single task and enable the single task to take effect immediately under the condition of not influencing other services and other timing tasks, and the specific implementation mode is as follows: maintaining two ConcurrentHashMaps of static final types, "FUTURE _ MAP" and "SERVICE _ MAP" and a task handle object, storing the Future object of the task into the FUTURE _ MAP and storing the task body into the SERVICE _ MAP each time the task is newly built, when modifying the task, only needing to obtain the Future object of the task from the FUTURE _ MAP and call the cancel method to cancel the task in the current task queue in the running state, then taking out the task body from the SERVICE _ MAP for updating, then re-adding the task body into the task queue through the task handle, and finally updating the FUTURE _ MAP and the SERVICE _ MAP to ensure that the latest task object is obtained in the next updating.

According to the scheme, the assessment setting information is persisted in the database, and even if the system is down, the system can automatically read the relevant information from the database and update the timing task after being restarted, so that the normal operation of the assessment process after the system fault is recovered is ensured. By the dynamic updating method of the timing task, the problems that the traditional timing task cannot be updated during operation, the service must be restarted to update, a new task cannot be immediately effective after updating and the like are solved, and the dynamic adjustment of parameters such as the task period, the execution frequency and the like under the condition of no shutdown is realized.

(2) Examination pending and data billboard module

The examination pending and data billboard module relates to evaluation scoring and data display of daily work and various project work of workers. In the examination opening time period, the user scores, modifies and submits the working performance of the employee in the examination interval according to the examination items and the examination important points thereof, and the flow is shown in fig. 7. Each organization responsible person directly scores the direct staff in the assessment to-be-done page (figure 8), clicks a submission button after the scoring is finished, submits the data to a superior leader for auditing, the superior leader needs to audit assessment details of indirect subordinate staff in a data billboard page (figure 9) in addition to the assessment to-be-done page for scoring the direct staff, and the assessment score of the indirect subordinate staff can be improved or reduced on the basis of the original score by adjusting an additional score mode.

In the business process, the upper and lower hierarchical relation of an organization and the job level of a job are combined, the submission state is _ committed is set as the job level of the job when the assessment data of the job is initialized, only the assessment records with the submission state field more than or equal to the leader job level-1 in the assessment records of the job under the leader (including direct subordinate and indirect subordinate) are returned on a data billboard page, and the submission state is _ committed is set as the job level of the leader when the assessment records of the job are submitted by the leader under the leader.

The advantages of this design are: for the directly subordinate, the initial submitting state of the assessment record meets the visibility requirement and can be directly displayed in the data billboard of the leader; for indirect subordinates, only after the examination records are submitted by the direct subordinates, the examination records are visible to leadership in the data billboard, so that the indirect subordinates are closer to real examination services, scientific data visibility is guaranteed, and the problem of dirty reading in the isolation level Read unommitted database is avoided.

The data billboard module realizes the visualization of the assessment data through the grouping statistics and the transverse and longitudinal comparison of the assessment data. As shown in fig. 10, the information of the registered staff is obtained according to the user information of the login user, and then the information of the organization structure is associated through the staff information, so that the excellent staff, the overall assessment situation and the assessment situation of each organization staff in all the managed staff are subjected to multi-angle and visual chart display, and the macro control of the enterprise managers on the staff work is facilitated.

Third, safety authentication module

The security authentication module provides services such as key security encryption and storage, user identity authentication in a full life cycle, common network security attack protection and the like for a user, and comprises a user information security protection module, a user identity authentication module and a network security protection module.

(1) User information safety protection module

The user information security protection module is used for ensuring the security of personal information of a system user, and the specific implementation mode is as follows:

(a) a high security user password generation mechanism is proposed and applied:

first, a salt is generated at the client using a cryptographically secure random number (SecureRandom).

Secondly, the password character string is converted into a byte array in a UTF-8 encoding format, and the byte array is encrypted by a SHA256 algorithm (or other encryption algorithms which cannot be recovered reversely) once.

And thirdly, the encrypted byte array is converted into a hexadecimal character string.

And fourthly, splicing the character string in the third step with the salinity value in the third step to form a new character string, and performing the third step and the fourth step again by taking the character string as a password character string, wherein the character string at the moment is the ciphertext after final encryption.

(b) The salt value and the ciphertext are stored on different servers separately, and the risk that the password and the salt value are acquired by an attacker at the same time is reduced.

(2) User identity authentication module

The user identity authentication module is used for verifying the identity of a user in the process of communicating from the client to the server, and the specific implementation mode is as follows:

(a) the HTTPS protocol is used for communication, the problems of insufficient plaintext transmission and data integrity verification of the HTTP protocol are solved, on the basis, the AES encryption algorithm is adopted at the client side for encrypting the password during login of the user, and the correctness of the password is verified after decryption is carried out at the server side.

(b) The token containing the user information is added to the server communication data at the client through the token technology, in order to ensure that the user information is not stolen in the communication process, an RSA algorithm is used for generating a public key and a private key of a certain secret key, a private key signature is adopted when the token is generated, the public key is adopted for verifying the signature when the signature is decrypted, the signature of the user cannot be forged under the condition that the private key cannot be obtained, the user identity can be uniquely confirmed, and the process is shown in figure 11.

(3) Network safety protection module

The network security protection module is used for protecting common network security attacks (XSS, CSRF), and the storage strategy of the user token at the client is matched with the CSRF token generated at the server, so that cross-site scripting attacks and illegal site stealing of user credentials at the client are completely eradicated, and the situation that a browser is deceived by a user name to send an illegal request to the server is avoided. The specific implementation mode is as follows:

(a) protection against XSS (cross site scripting attack):

when using token technology for identity authentication, the client needs to store the token. If the token is stored in the LocalStorage and the SessionsStorage of the client, the token is easily and directly acquired by malicious JavaScript, and generally, a plurality of Javascript class libraries of third parties are used in projects, so the method is easily attacked by XSS. Therefore, the token should be stored in the Cookie of the browser, and the generated token is directly Set in the Set-Cookie field of the HTTP Response Header (Response Header) after the user successfully logs in, so that the client reads the Set-Cookie field in the Response Header and sets the Set-Cookie field as the Cookie after receiving the Response of the server, and the Cookie is automatically taken in each subsequent request of the client to the server. Therefore, the Cookie can make the Javascript unable to access the Cookie by specifying the HttpOnly, and XSS attack is avoided.

(b) Prevention of CSRF (cross-site request forgery):

the use of cookies brings other problems, the most serious of which is CSRF attack, in which an attacker holds a trusted user Cookie, and since the browser is authenticated once, the visited website can be regarded as a real user operation, so that the attacker can perform illegal operation on the system by using the identity of the user. In order to avoid the risk of CSRF attack, the system adopts the following measures:

checking whether a Host and a Host in a Referer in a Request header (Request Headers) are the same or not, if the Host and the Host are different, searching in a domain name white list, and if the Host and the Host are not found in the white list, determining that the Host is a CSRF attack and directly intercepting by using an Interceptor (Interceptor).

When a sensitive request (POST, PUT, DELETE) is carried out each time, a client side requests a server side for a randomly generated CSRF-token, the client side takes the CSRF-token and then PUTs the CSRF-token into a request head of the sensitive request and sends the CSRF-token to the server, the server side verifies the CSRF-token in an interceptor, if the CSRF-token is matched with the CSRF-token, the CSRF attack is released, and otherwise, the CSRF attack is considered to be intercepted. As an attacker cannot forge the CSRF-token and the random CSRF-tokens generated by each sensitive request are different, the method can effectively inhibit the CSRF attack.

Finally, it should be noted that the above embodiments are described in detail and specific examples, but only for illustrating the technical solutions of the present invention and not for limiting the same, and those skilled in the art should understand that several variations and modifications can be made without departing from the concept of the present invention, and these embodiments are included in the protection scope of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
