Solution
If your controller class are as follows
@Controller("/userinfo")
public class UserController {
@RequestMapping(method=RequestMethod.POST)
public String userInfo(@RequestBody User user){
}
}
@Controller("/userproject")
public class UserProjectController {
@RequestMapping(method=RequestMethod.POST)
public String userProject(@RequestBody UserProject userProject){
}
}
//Then Use value Element of @RequestMapping as follows
@Controller
public class UserController {
@RequestMapping(value = "/getuserinfo", method=RequestMethod.POST)
public String userInfo(@RequestBody User user){
}
}
@Controller
public class UserProjectController {
//Note value in both controller requestMapping should be different
@RequestMapping(value = "/getuserproject",method=RequestMethod.POST)
public String userProject(@RequestBody UserProject userProject){
}
}
