Call the Addsession method3. Use the Usesession callback (Usesession need to be called before the Usemvc () method)The sp

environments, the same problem can crash the system. For a person who has handled a large system that uses XML, he has encountered this problem. It is often tedious to write a loading process, and you need to update and rewrite the code frequently because of changes in the data source or the target Java class. Here I want to introduce another solution, which is to use mappings, which typically use less coding and can update themselves after the targe
