Description

A method for automatic generation of web services across data sources

technical field

The invention relates to the field of web service generating methods, in particular to a method for automatically generating web services across data sources.

Background technique

In recent years, various units and organizations have gradually increased their investment in informatization construction. At the same time, information technology has gradually matured. In this context, various units have built many information systems with different functions. These systems are relatively independent, but depend on each other for their functions. In order to realize the interactive operation between the systems, people often choose to open web services.

Different from local services, web services call resources of other systems through the network. Therefore, web services have three advantages: platform-independent, programming language-independent, easy to upgrade and maintain. Web services can be used regardless of the platform; as long as the relevant protocols are followed, any programming language can be used to request web services from other systems; because there is no need to consider client compatibility issues, the deployment, upgrade and maintenance of web services are relatively easy. Simple.

There are two main ways to use Web services, one is the restful interface method based on json, and the other is the webservice method based on WSDL files. Due to the light weight of json and the ease of use of the restful interface, the restful interface method based on json has become the mainstream. Prior to this, various systems generally adopted the webservice method based on WSDL files for interoperability.

The system designer will open corresponding web services to the system according to the current or expected needs. However, with the operation of the system, new web service requirements will inevitably be generated. At this time, people often develop according to these new requirements and then deploy them online. This method is acceptable for systems with few new requirements, but for systems that frequently generate new requirements, the flexibility is too poor. The demand side needs to wait for the web service to be developed, tested, and deployed before it can be used. On the other hand, the provider also needs to invest in specialized manpower to complete the above work.

Contents of the invention

The technical task of the present invention is to provide a method for automatically generating web services across data sources in view of the above-mentioned deficiencies in the prior art.

The technical task of the present invention is realized in the following manner: a method for automatically generating web services across data sources, which is characterized in that the return result class, web services and configuration files are dynamically generated successively according to the configuration of the user, and then the web services are issued, including The following specific steps:

1) Configure the information needed to generate web services

The required configuration information includes: operation type, request parameters and return value, and result filter conditions;

2) Generate executable sql statements according to the configuration

According to the operation type configured in step 1), request parameters and return values, and result filter conditions, dynamically generate SQL statements;

3) Save the configured web service information and sql statement

Persistently store the sql statement and web service configuration information generated in step 2);

4) Generate a data model for saving a single data record

Dynamically generate the data model code for saving a single data record according to the configured return value information;

5) Generate service return value class;

6) Generate web services and related configuration files;

7) Publish the web service.

Preferably, in step 1), the required configuration information also includes the data source required by the web service, the name and URL of the web service, the version number, and the service description.

The operation type mentioned in step 1) refers to add, modify, delete or query.

The return value category described in step 5) includes return value status code, return value description, total number of pages, current page number and specific data.

Compared with the prior art, the cross-data source web service automatic generation method of the present invention has the following beneficial effects:

(1) When a new web service requirement is generated, the web service that meets the requirement can be automatically generated through simple configuration by the administrator, which is flexible and efficient, and greatly improves the response time of the new web service requirement.

(2) This method can provide a consistent web service implementation solution, which is more friendly to web service users.

(3) This method makes the database operation more secure and controllable.

Detailed ways

The method for automatically generating web services across data sources of the present invention will be described in detail below with specific embodiments.

Example:

Realize the cross-data-source web service automatic generation method of the present invention to dynamically generate return result class, web service and configuration file sequentially according to the configuration of the user, and then publish the web service. So far, web services can be used in restful or WSDL mode, thus avoiding manual writing of web services.

The specific steps to realize the above method are:

1) Configure the information needed to generate web services

The required configuration information includes: data source required by the web service, operation type, request parameters and return value, result filter conditions, web service name and URL, version number, and service description. The operation type refers to add, modify, delete or query;

2) Generate executable sql statements according to the configuration

Dynamically generate SQL statements according to the operation type, request parameters, return value, and filter conditions configured in step 1);

3) Save the configured web service information and sql statement

Persistently store the sql statement and other web service configuration information generated in step 2);

4) Generate a data model for saving a single data record

Dynamically generate the data model code for saving a single data record according to the configured return value information;

5) Generate service return value class

The return value class includes return value status code, return value description, total page number, current page number, and specific data;

6) Generate web services and related configuration files

According to the configuration, generate other configuration files required by the web service;

7) Automatically publish web services.
