错误呈现

测试代码如下

@Test
    public void indexData() throws IOException {
        IndexRequest request = new IndexRequest("users");
        request.id("1");
        //request.source("user", "kimchy","postDate", new Date(),"message", "trying out Elasticsearch");
        User user = new User();
        user.setUserName("zhangsan");
        user.setAge(20);
        user.setGender("男");
        String josnString = JSON.toJSONString(user);
        request.source(josnString, XContentType.JSON);  //要保存的内容

        //执行操作
        IndexResponse index = client.index(request, GulimallElasticSearchConfig.COMMON_OPTIONS);
        System.out.println(index);
        //提取有用的响应数据
    }

代码是没什么问题的，但是报了一个错误
