Question

@Controller("/UserAction")
@RequestMapping("/greet.json")
public class UserAction extends BaseAction {

@RequestMapping(value = "/hello", method = RequestMethod.GET)

public void hello(HttpServletRequest request,HttpServletResponse response) {

    System.out.println("a");
}

@RequestMapping(value = "/word", method = RequestMethod.GET)

public void word(HttpServletRequest request,HttpServletResponse response) {


    System.out.println("123123@@@");
}

}

当我看http://localhost:8080/ProjectName/greet.json/hello时和http://localhost:8080/ProjectName/greet.json/word 不能执行syso方法

我认为你有2个注释混淆了你的操作，试着只使用它：

@Controller
public class UserAction extends BaseAction {

@RequestMapping(value = "/greet.json/hello", method = RequestMethod.GET)

public void hello(HttpServletRequest request,HttpServletResponse response) {

    System.out.println("a");
}

@RequestMapping(value = "/greet.json/word", method = RequestMethod.GET)

public void word(HttpServletRequest request,HttpServletResponse response) {


     System.out.println("123123@@@");
}

如果你想使用你的控制器的通用路径添加 @Controller（＆＃34; /文件版本＆＃34）

以后用

的每个方法

@RequestMapping("/specificEndPoint")

spring mvc request method 404错误
