找不到弹簧控制器

Question

我无法解决这个问题，我是 spring 新手，所以它可能很愚蠢，但我的 angular post 请求没有与 java spring 控制器通信...

我的角码..

function check($scope,$http){
 $scope.go = function (){
      var go = $http({
          method:'POST',
      url:'/addentry/pp',
  data : $scope.abc
  })  ;
};

我的添加入口类...

package all;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
/**
*
* @author om
*/
@Controller
@RequestMapping("/addentry")
public class addentry {
@RequestMapping(value = "/addentry/pp" ,method = RequestMethod.POST)
public @ResponseBody String reply(@RequestParam("name") String        name,@RequestParam("pass") String pass){
    return "hello";
}     
}

但我收到 404 错误....（找不到附加条目/pp）

Answer 1

您的@RequestMapping 注释有误。你已经用@RequestMapping 注释了你的控制器和方法（这很好），但是/addentry 被定义了两次。 Spring会回复/addentry/addentry/pp。

从您的控制器（类定义）或您的方法中删除 /addentry。
