Solve the jar package conflict when integration of existing projects and cxf ws Functions

Simplify and adjust the original document management project, and provide WebService interfaces for other applications of the customer. WS uses cxf to provide simple functions, but the jar provided by the original project conflicts with the package on which cxf depends. First, in the integration process, remove some jar files used by cxf to be used in the project. After the project compilation is normal, adjust the function slimming.

 

The whole slimming process did not use the cxf tool to generate the WSDL file and then generate the client service, but simply wrote a client call. It can transmit information through WS and access the documentation platform through the returned connection for document operations. However, since the WS service needs to be provided to the customer, the WSDL file must be provided.

 

The integration of the project to obtain the WSDL file produces a series of problems, but there is no such error in another independent ws project. The record during integration is of great help to the subsequent work. After removing some jar packages, it is easy to understand that the original project conflicts with the newly added ws dependency jar. First, make sure that either side of the two is not referenced, and then try to use one of them to run the project, which will cause problems. Because the backend of the project depends on the filenet product, some jar files cannot be replaced easily. Later debugging found that these jar packages are provided by different manufacturers and have different paths, even some jar packages change the classes (classes in different jar packages) that the original cxf generates the WSDL ).

 

Because these conflicts are generated using cxf to generate the WSDL, instead of other functional development or running processes, you only need to exclude these temporarily problematic jar projects, then, retrieve the jar (excluded) required by the application of the original document.

 

A local experiment project can create a WSDL. Download the source code from the cxf official website and debug its logic. The jar used in this process, different from the jar generated during the WSDL debugging process in a problematic project, the cxf dependency is replaced or the jar cannot be used at all, until it enters the correct jar environment according to the normal logic.

 

Now the project can generate the WSDL file. Restore the jar on which the original project depends, deploy it, generate a client based on the WSDL, and test the call. The following is an example of an error log.
