spring boot 解决Ajax 跨域问题

Ajax 跨域 请求 spring boot 的跨域问题

Ajax 跨域请求spring boot 时 前端报错

出现跨域错误

后端代码

 @RequestMapping("/getArticles")
    @ResponseBody
    public JSONObject toArticle(@RequestParam(value = "page") int currentPage){
        if(currentPage == 0){currentPage = 1;}
        JSONObject jsonObject = new JSONObject();
        ArticlePage articlePage = new ArticlePage(currentPage,10);
        Page<Article> page = articleServiceImp.getUserPageWrapperPage(articlePage);
        List<Article> articleList = page.getRecords();
        jsonObject.put("articles", articleList);
        jsonObject.put("page", 1);
        jsonObject.put("code",200);
        jsonObject.put("status",constantPool.success);
        return jsonObject;
    }

前端代码

$.ajax({
            url:"http://127.0.0.1:8080/getArticles?page="+page,
            methed:"post",
            success: function (data) {
                    console.log(data)
                     //假设你的列表返回在data集合中
                    layui.each(data, function(index, item){
                    lis.push('
'+ item.title +'
');
                    }); 
        //执行下一页渲染，第二参数为：满足“加载更多”的条件，即后面仍有分页
        //pages为Ajax返回的总页数，只有当前页小于总页数的情况下，才会继续出现加载更多
            next(lis.join(''), page < res.pages);    
            },
            error:function(res){

            }
        })

问题比较简单 但是也比较折磨

解决方法

你没看错 就是加一个 @CrossOrigin 注解

 @RequestMapping("/getArticles")
    @ResponseBody
    @CrossOrigin
    public JSONObject toArticle(@RequestParam(value = "page") int currentPage){
        if(currentPage == 0){currentPage = 1;}
        JSONObject jsonObject = new JSONObject();
        ArticlePage articlePage = new ArticlePage(currentPage,10);
        Page<Article> page = articleServiceImp.getUserPageWrapperPage(articlePage);
        List<Article> articleList = page.getRecords();
        jsonObject.put("articles", articleList);
        jsonObject.put("page", 1);
        jsonObject.put("code",200);
        jsonObject.put("status",constantPool.success);
        return jsonObject;
    }

已解决
