从错误信息可以看出:
-
UserController有一个save方法，访问路径为
http://localhost/save -
BookController也有一个save方法，访问路径为
http://localhost/save -
当访问
http://localhost/saved的时候，到底是访问UserController还是BookController?
@Controller
@RequestMapping("/book")
public class BookController {
@RequestMapping("/save")
@ResponseBody
public String save(){
System.out.println("book save ...");
return "{'module':'book save'}";
}
}
改成这样就好
