Description
Technical Field
The invention belongs to the technical field of software, and relates to a refreshing method of an extensible non-restart dynamic parameter of an application server based on configuration files and unified parameter configuration management.
Background
Configuration parameter management is an important component for application server based programs, such as the J2EE application. The start and operation of the service application depend on the configuration parameters, and whether the configuration parameter values are correct or not determines whether the application can be started and operated normally or not. On the other hand, if the running application can dynamically add parameters or change the values of the existing parameters and make them effective without restarting the application server, the running application is encouraged in terms of the extensibility of the application and the user friendliness (without interrupting the service provision of the application).
For example, an application is assumed that its login service is provided externally and independently, and the single-sign-on authentication address is configured in the application as a configuration item. Then the configuration item needs to be modified and validated when the application needs to switch to a new login authentication service. If the parameters cannot be dynamically refreshed, the application server needs to be restarted after the configuration is modified, and the service provided by the application to the outside is interrupted in the period, so that the use experience of the user is reduced. With the mechanism of dynamically refreshing the parameters, the new single sign-on address can take effect at the moment of refreshing the parameters, thereby saving the operation and maintenance cost and improving the user experience.
When the expansion and the refresh of the parameters are to be realized, the difficulty is not high under the condition that the application server can be restarted, the parameters are only required to be modified and then the application is released again, and the parameters are read from the codes when the application is released. However, if dynamic refresh of dynamically added parameters and existing parameters needs to be implemented without restarting the application server, the parameter types need to be well planned and a mature and reliable refresh mechanism needs to be designed.
In view of the necessity of dynamically refreshing configuration parameters of an application server without restarting, it is desirable to provide a method for dynamically expanding and refreshing configuration parameters to adapt to the application server-based program usage, and the method also takes into account the scenario of configuration refresh of different machines in the cluster situation.
Disclosure of Invention
The invention aims to provide a refreshing method for an extensible non-restarting dynamic configuration parameter of an application server, which is based on configuration files and unified parameter configuration management, utilizes a cache value of the parameter in a memory to provide service for the outside, and performs parameter reading and dynamic refreshing on a single or a plurality of server nodes under the condition of supporting a cluster so as to dynamically expand and refresh the configuration parameter value of the application server.
The aim of the invention is achieved by the following technical solutions:
a refresh method of extensible non-restart dynamic configuration parameters of an application server is characterized in that the method comprises the following steps:
1) establishing a dynamic configuration parameter refreshing integration framework, wherein the framework content comprises: a service application end and a unified parameter configuration management end; the service application terminal represents a service application; the service application needs to perform type division and design on configuration parameters; configuration parameters are divided into two categories: based on the parameters of the configuration file and the parameters capable of carrying out unified configuration; unified parameter configuration management end: the method is a uniform parameter configuration management end; in order to make the unified configuration of the parameters clearer and more reasonable, the concepts of a physical system and a physical address are required to be introduced; physical system: the physical system corresponds to a deployment package of the business application, and the deployment of one business application can register one physical system at a management end with unified parameter configuration; different physical systems distinguish different service applications, and each physical system generates a pair of public key and private key for asymmetric encryption when generating; physical deployment address: the physical system deployment address is different deployment addresses of a designated physical system and consists of an address IP and a PORT, and because different nodes in the cluster or the same application provides slightly different services through configuration, different deployments of the same deployment package need to be distinguished;
2) the service application end is deployed on line and provides a refresh URL;
3) configuring a physical system and setting a physical deployment address at a unified parameter configuration management end;
4) adding physical system parameters used by service application in the physical system parameter setting of the unified parameter configuration management end, setting parameter values, and setting a refresh URL after the completion.

(2) acquiring a service address of the uniform configuration parameter from the configuration file parameter and calling; and clearing the unified configuration related parameters in the original memory after successful calling, and resetting the obtained result into the memory.
The unified parameter configuration management end provides two functions: physical system registration and physical system parameter setting, and an interface for acquiring the system parameters.
The parameters based on the configuration file or the uniformly configured parameters are obtained when the service application is started and cached in the memory of the application server, in other words, the configuration parameter values used by the service application are all parameter values cached in the memory of the service application server instead of the parameter values obtained in real time. The business application itself needs to provide a provisioning service (referred to as a refresh URL) to refresh the configuration parameter values in its memory.
Physical system registration: registering a physical system corresponding to the service application deployment package and registering a corresponding physical deployment address; setting physical system parameters: setting physical system configuration parameters, namely unified configuration parameters of corresponding business applications; the physical system parameters comprise parameter names, parameter codes, parameter values, parameter configuration descriptions, whether the parameters are consistent, whether the parameters are encrypted and whether all server parameters are consistent; the parameter coding is the coding appointed with the service application; if the parameter is set to be encrypted, the value of the parameter is encrypted and stored by a pubKey generated when the physical system generates the parameter; if the parameters are consistent, setting values on the physical system for the parameter values, wherein the parameter values obtained by all the physical deployment addresses are consistent; otherwise, setting the parameter value on the physical deployment address under the physical system; in the physical system parameter setting, the functions of setting a refresh URL and refreshing server parameters are provided; the set refreshing URL is the URL of the configuration parameters in the memory of the refreshing body provided by the corresponding service application; the refresh server parameter is the result of calling the refresh URL of the physical deployment address to refresh the configuration parameter and return success or failure;

(2) A unified set of parameter setting mechanism is convenient for promote in the enterprise, reduces the cost of repeated study.
(3) All the service application parameters can be managed in a unified way, and professional management authorization and unified maintenance are facilitated.
(4) For the business application, dynamic configuration expansion of the configuration parameters can be carried out, and the configuration parameters are refreshed without restarting an application server.
