@MultipartConfig override in web.xml

Question

So I have this servlet :

    @WebServlet(name = \"StudentRegistrationUsn\", urlPatterns = {\"/university/student/registration\"})
@MultipartConfig(maxFileSiz         


        

Answer 1

The is missing in web.xml. This exception is basically caused because the name of the to-be-loaded class is null.

In fact, you need to redefine everything, including the URL patterns.

    StudentRegistrationUsn
    com.example.StudentRegistrationUsn
    
        10485760
        20971520
        5242880
    


    StudentRegistrationUsn
    /university/student/registration
