java - 关于angularjs向后台请求数据以及解析的问题

Question

我在angularjs的controller中发送了http请求，请求到后台能够得到返回数据，可是响应是404，data为undefined.
js文件是加载到infoUpdate.html页面中，每次页面中的controller创建后，会自动调用js中的controller，发送http请求到java后台。

下面是js代码：

angular.module('infoUpdate',[])
.controller('infoUpdateController',function($scope,$http){
    $scope.subscriberData = {},
    $http({
        method: 'GET',
        url: 'http://localhost:8080/Weixin/getSubscriberInfo?subscriberOpenId=ojXQbxLbEY9wnrFgnL5ODCyVVpnc'
    }).success(function(data,status){
       /* $scope.subscriberData.phone = data.phone;
        $scope.subscriberData.email = data.email;
        $scope.subscriberData.kindleEmail = data.kindleEmail;*/
        alert("findInfo successfully! phone:"+ data.email);
    }).error(function(data,status){
        alert("findInfo error! data.phone:" + data.phone + " status:" + status);
    })
});

后台java相关的代码如下：

package com.kindlepocket.web.controller;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import java.util.Map;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.kindlepocket.web.pojo.HttpResult;
import com.kindlepocket.web.service.SubscriberService;
import org.apache.commons.lang3.StringUtils;
import org.apache.log4j.Logger;
import org.dom4j.DocumentException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import com.kindlepocket.web.service.TextBookInfoSearchService;
import com.kindlepocket.web.util.CheckUtil;
import com.kindlepocket.web.util.MessageUtil;

@Controller
@RequestMapping("/Weixin")
public class KindlePocketController {

    private static final long serialVersionUID = 1L;

    private static String SUBSCRIBER_OPENID = null;

    @Autowired
    private TextBookInfoSearchService searchService;

    @Autowired
    private SubscriberService ssbService;

    private static Logger logger = Logger.getLogger(KindlePocketController.class);

    private static final ObjectMapper MAPPER = new ObjectMapper();

    @RequestMapping(value = "/getSubscriberInfo", method=RequestMethod.GET)
    private String getSubscriberInfo(@RequestParam("subscriberOpenId")String subscriberOpenId,HttpServletResponse response){
        if(logger.isInfoEnabled()){
            logger.info("search for subscriber info; openId: "+subscriberOpenId);
        }
        HttpResult result = this.ssbService.findSubscriberInfo(subscriberOpenId);
        if(logger.isInfoEnabled()){
            logger.info("searching result: "+ result);
        }
            //JsonNode node = MAPPER.readTree(result.toString());
            //response.setHeader("Access-Control-Allow-Origin", "*");
        return result.getBody();
    }
}

result.getBody()的数据格式为:

{"id":"ojXQbxLbEY9wnrFgnL5ODCyVVpnc","userName":null,"phone":"15601905361","email":"kdnxjx@qq.com","emailPwd":"jdbxisbx","kindleEmail":"jdbxjx@kindle.com","subscribeDate":1466435475701}

页面会提示404错误：

angular-1.3.0.js:8452 GET http://localhost:8080/Weixin/getSubscriberInfo?subscriberOpenId=ojXQbxLbEY9wnrFgnL5ODCyVVpnc 404 (Not Found)

请问我应该如何正确返回这个页面并解析出数据呢？谢谢

Answer 1

修正方法：アノテーション@Controllerを@RestController

に修正

Answer 2

特別な設定がない場合は、result.getBody() 文字列の JSP を検索する必要がありますが、これは明らかにあなたが望む結果ではありません。
メソッドの前に設定を試してください@ResponseBody

リーリー

または @Controller を @RestController に変更します

Answer 3

angular は ajax を使用し、メソッドには @Responsbody が必要です。そうでない場合は、返された結果に基づいて jsp を検索できます。
