In the system integration stage, to guarantee that the calling of ESB interface is in specified operation flow, by specific process list Member is initiated, and the present invention provides the application integration of loose coupling, and the application integration for electrical distribution formula isomerous environment provides solution Scheme.Function modeling provided by the application system of the different owners will be belonged to service class, the interconnection of system only focuses on The type of business function rather than the definition mode of interface, less it should be understood that the respectively realization of internal system.It is used on ESB Internal system or the change of the state of outside are converted into servicing by the message model of standard by the notice or subscription/publication of message The response of interface.

ESB is that the integrated of application provides message routing functionality, message format conversion function, service-seeking function, agreement Adapter conversion function and asynchronous event-driven mechanism, trans-departmental, cross-system data exchange, operation flow interaction and Distributed data stores and accesses.Using the application of different technologies realization by the encapsulation of service interface, included by itself Function be articulated in bus.If having initiated service request using to bus system, bus passes through the conversion to request message The solicited message of different application itself is converted into the Rules Message of bus system Unify legislation, is then taken according to Rules Message The content of band carries out routing operations to request message；Different request messages is sent to different event-driven middlewares, by Middleware initiates the calling to service interface, and result is fed back to event-driven middleware；Middleware receive after result according to It is Resealed using the format for initiating request, and passes to requestor.

It by the functional development in application integration to ESB is referred to for guiding according to different business demands with operation flow What kind of interactive mode fixed application needs, and then needs to carry out tissue layout to service interface according to operation flow.The present invention Operation flow can be described in the form of template, when service interface calling occurs, check whether the calling accords with Close the definition of operation flow template.

In order to guarantee the complete and effective of the act of authorization, need to carry out ongoing Authorized operation the constraint of permission. The present invention completes user to the access mandate of shared resource, to authorization privilege using dynamic authorization and Static authorization two ways Restricted problem need to be explicitly defined in Static authorization part.Static authorization is that control user connects the shared resource in system, service The permissions such as mouth, database and document read-write, while also needing to indicate that operation flow needs the workflow template of foundation.For static state Authorization, Permission Constraints rule has been worked out in the access control policy can only be influenced operated by administrator with the authorization for ensuring single Apply user so that authorization illegally will not be transmitted and be destroyed.To guarantee that administrator defines tactful not by illegal transmitting And succession, the access control model use unidirectional authorization path, guarantee that the definition of delegated strategy does not repeat and authorizes path not Intersection, different delegated strategies individually possess authorization path.The authorization incomplete strategy in path will be dropped, and meet trust condition Strategy described in different authorization levels by different nodes, authorize on path there is no intersecting or repeating, determine Transfer of right caused by inheriting or reusing will not occur for the strategy of justice.

Firstly, the completion of Static authorization part needs following three aspects to meet simultaneously: 1) this is executed to shared resource Operation required for authority definition in the property set of user；2) operation set of user includes this Business Stream list executed Member；3) the requested authorization step of user's operation meets the definition of task template.

Dynamic authorization part is the state of the procedure information and current grant step according to workflow on task template, real The access control rule applied.When routine interface is called, the protection state of step is authorized to need to meet safety regulation, i.e., if met Flow of task) limitation, and there is normal protection state, then can be authorized to execution.

For the requirement of access control policy, the active node in the above workflow is carried out to the addition of user class.Work What Lian took over a job Dong Unit member in flowing is activity jump condition, the condition have recorded active unit be transferred to from a certain activity it is another Activity, and have recorded the temporal information of transfer and the service interface that step transfer is called.Activity jump condition has recorded activity The time of transfer occurs to shift the state of workflow when called interface and transfer occur, it can clearly describe work Whether correlation and workflow between unit normally circulate, these information in combination in integrated system shared resource it is controlled Access guarantees that the access of interface is in specific workflow, and is occurred in specific flow elements, so as to electricity The access of shared resource is guaranteed in power application integration environment.

Workflow is initiated by specific application, and is monitored and run by integrated system, based on workflow template, to business The operation order of flow elements is controlled.When interface is initiated in a certain application to be called, integrated system is according to the tune of application Judge whether the application is to initiate a new workflow with information, if the calling is to initiate a new workflow Journey, then the security management program of integrated system judges whether current application has operating right to the shared resource in process；If The program possesses associated rights, and security management program judges whether the program has permission the initiation operation flow, if this is answered The workflow is initiated with having permission, integrated system can load workflow template, monitoring, initial of the creation for the operation flow Change Workflow messages, then completes the creation work of new business process.If be not meant to using made service interface calling New process is initiated, safety management system can carry out the matching of workflow template according to the operation flow at the place of service call, If the calling meets the definition of workflow, and active state is carried out according to circulation sequence, then is able to satisfy dynamic and awards The needs of power.

To realize the structure of container for supporting functional semantics in the data integration based on ESB Enterprise Service Bus, and apply In each operation system, each endpoint server is both configured to independent JBI container, the intermediate node in counter structure and Leaf node；Center service bus provides global routing iinformation and management, corresponding root node.Message transmission between endpoint server It is undertaken by JMS message-oriented middleware.

Service search mechanism is expressed as: service user sends service request to local container, and JBI bundled components receive should Request, and the routing of local standardized message is passed the requests to, if finding matched service in local service registration table, Then it is supplied to user；Otherwise forwarding service is called, the response to forwarding service is to transmit a request to upper layer using service-Engine Container；Continue this process, until finding suitable service.

Message transmission between local container and upper layer container is undertaken by JMS.The message routing of local container node will disappear Breath is routed by the message that JMS message-oriented middleware is sent to upper layer container node, then is handled by the message routing forwarding.Each Message routing in JBI node is owned by the route messages queue of oneself, each message routing on system JMS message server The message queue for monitoring oneself is just handled when discovery has the message sent, which is forwarded to purpose component.

In order to guarantee that multiple deployment of the high reliability there are same system, same service have multiple examples to run at the same time； For specific service request, user need to select a most the superior according to service quality evaluation in candidate service, as clothes It is engaged in the routing destination requested, realizing the dynamic message routing based on QoS.According to each ISP's when program is run QoS dynamic updates the routing iinformation in routing table, the destination for selecting message to send.

Service valuation, service testing and service selecting module are added on ESB respective service component, and dynamic message is set It routes library and stores the container of historical test data.Wherein dynamic message routing library is that a storage can use routing iinformation XML file constantly selects new service to be stored in routing library in integrated system operational process, takes out address of service from routing library The QoS test of each service is carried out, and test result is saved as into historical test data；COMPREHENSIVE CALCULATING test data is to assess clothes Business, chooses optimal service supplier therein to update the routing in current routing table.

In view of needing largely directly to be grasped in power information field to data such as electronic drawings and archives, Project contract etc. Make, the present invention directly encapsulates partial data by the way of data service, provides the access interface of concentration for application layer. The bottom data that various isomeries are integrated by data service is looked into including the SQL statement that can be used in relevant database The data of inquiry；The data that text file or web data etc. cannot use query statement to inquire；It further include that other pass through Web service The data of access.Data service is directly packaged bottom data, rather than accesses data by application service.

The framework of data service is divided into four layers: data Layer, data service layer, SOA layers and application layer.Data Layer includes electricity Various heterogeneous data sources used in the application of power enterprise, as relevant database, XML database and other data services are supported Data format.Data service layer provides single access point for the access data of electric power enterprise internal applications or SOA layers.Number Following functions are provided according to service layer: normal data access operation, such as creation, reading, search and deletion data；Data are provided Data mapping and parsing between source, ISP and basic data source model, shield database platform difference；Use file When with catalogue as data source, non-database architectural difference is shielded.It is functional to construct the above-mentioned institute of data service layer encapsulation, concentrates institute Some data service codes can provide the access details of data to the object in other application service.

Using data service acquisition data are directly accessed, can also be accessed by SOA layers.In distributed-distribution system In, it can be registered by searching for UDDI and call data service to obtain public information.Business datum clothes relevant for enterprise Business, can be supplied to the visitor of enterprises by way of subscribing on ESB.Service requester is not aware that specific access Be which kind of service, unified access can only be carried out by ESB.Data service and other Web services are likely to be at the shape of equity State is all accessed by ESB, it is also possible to be called by Web service.Change to service access interface in special circumstances is led to It crosses and modifies existing Web service, encapsulation of data service, without modifying service request interface in the application.

Various programs in application layer can directly access data service, can also access data service by ESB, can be with The WSDL of data service is searched by the registration above UDDI.

The service request response process flow of ISP and service requester difference is as follows:

1. the service of ISP's publication carries out semantic description in conjunction with QoS ontology and domain body, then passes through registration Center enters in Enterprise Service Bus, is ultimately stored in Web container for calling；

2. semantic description is carried out by system first after service requester proposes demand for services, by service request information semanteme Change, then service request is decomposed, in conjunction with ontology knowledge, according to discovery above, selection, combinational algorithm, final general The service response result matched returns to user.

For the exception in data service combination, the present invention is classified as being operating abnormally nand function exception, is operating abnormally Expression refers to the problem during service operation, as service system is abnormal, Statistical different in terms of data format or content It is often abnormal etc. with service process；The non-functional abnormal expection or service for indicating current service and being unable to satisfy the evolution of user The scene that system is found the problem automatically according to environment and dynamic solves the problems, such as.

Data service is automatically adjusted when perceiving the abnormal conditions in environment, and certainly by service register center The case where moving the targeted issuing service of search and carry out abnormality processing, and passing through abnormality processing carries out for the dynamic of data service State adjustment.For being operating abnormally, sensor model is matched and is inquired to abnormal by prefabricated exception rules；For non-functional The abnormal process by exception service discovery, service discipline and service self-healing carries out planning and modeling again for data service, into one The framework for walking more new data service, to meet new demand for services.

Carry out abnormal monitoring by various dimensions to data service system: resource exception, QoS be abnormal, data sexual abnormality with Service procedure is abnormal, and abnormal rank definition is ranked up generated exception, by monitor it is abnormal into Row classification, to distribute it different treatment processes, principle of classification includes:

It is directed to the executive condition of the physical resource of data service system in the process of running, which includes for data Logic flow situation, network operation situation, running environment executive condition in service system, the meeting when resource exception fluctuation occurs Corresponding exception record is carried out using actual conditions according to resource, and then actively determine with operation exception, thus further Take abnormality processing；

To being monitored during data service operation for system nonfunctional space, service reliability, safety are contained Property, the indexs monitoring such as execution efficiency, can be according to the actual conditions of data service when QoS unusual fluctuations occur during monitoring It is recorded and takes corresponding treating method；

The data consistency and integrality being directed in data service implementation procedure monitor, data relevant to calculating logic Circulation process will perform corresponding processing operation when occurring abnormal；

In face of the functionality monitoring of data service, each sub-services being directed in data service carry out function monitor, together When monitoring sub-services between related information, when logic fluctuation occurs in data service system, flow monitoring will record lower corresponding Exception information is simultaneously chosen abnormality processing method progress abnormality processing appropriate and is repaired.

When an abnormality is discovered, it is performed corresponding processing according to abnormal classification to abnormal, if it is operation exception, first Corresponding abnormal solution is searched in abnormal library, and then searches for required reparation service in UDDI, while by abnormal feelings Condition is added in abnormal log.When in rule base be not present solution when, then directly pass through Service Matching algorithm from UDDI into Row similarity service search, and service replacement is carried out to data service by the algorithm based on compensation cost, if abnormal is non- Dysfunction then needs to handle data service by services selection, training and the process of self-healing.
