【中文标题】IOException：已建立的连接被主机中的软件中止

【英文标题】：ERR_INVALID_CHUNKED_ENCODING 200 machine

【问题描述】：

我想使用带有 ajax 的 Spring Boot 从数据库中获取数据，但出现错误 500。我检查了所有代码，但找不到服务器出错的原因。我可以在workbench 中检查下面的 sql 查询，它得到了完美的输出，但是 spring boot 触发错误。

Chrome 控制台：

GET http://localhost:8099/wholikepost?pstId=25 net::ERR_INVALID_CHUNKED_ENCODING 200

下面是我的代码：

存储库和服务

// Repository
public interface PostLikeRepo extends JpaRepository<LikePost, Integer>
    @Query(nativeQuery = true, value = "SELECT * FROM like_master WHERE post_id = ?")
    public List<LikePost> getTotalLikePopup(Integer id);


// Service
public class SomeServiceImpl implements SomeService

    @Autowired
    private PostLikeRepo PostLikeRepo;

    public List<LikePost> getTotalLikePopup(Integer Id)
       return this.PostLikeRepo.getTotalLikePopup(Id);
    

控制器

@RequestMapping(value = "/wholikepost", method = RequestMethod.GET)
@ResponseBody
public List<LikePost> getTotalLikePopup(HttpServletRequest req)

    List<LikePost> getWhoLikePost = this.SomeService.getTotalLikePopup(Integer.parseInt(req.getParameter("pstId")));
    return getWhoLikePost;

Ajax 请求

$(".like-style").on('click', function()
   let postId = parseInt($(this).attr("id").split("le")[1]); // get post id perfect
   $.ajax(
        type: "GET",
        url: "/wholikepost",
        data: pstId: postId ,
        success: function(res) 
            console.log(res);
        
    );
);

【参考方案1】：

99% 的几率您会受到以下问题的影响

您的 LikePost 实体通过 @ManyToMany 或 @OneToMany 注释具有循环依赖关系，因此在转换为 JSON 响应时，它会面临堆栈溢出错误，然后隐藏在与客户端的关闭连接后面。

已经有类似事件here

检查您是否可以在您的某些@ManyToMany 或@OneToMany 中添加@JsonIgnore，以及这是否可以消除错误。那么您就可以 100% 确定这是原因所在。
