java定时任务中java.lang.IllegalStateException: No thread-bound request found_Systemd的博客

问题描述：

xxljob定时任务中写了一个线程池，每次调用定时任务，都会起7条线程，进行数据传输，程序运行时报错：
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

bug原因：

线程池中的子线程获取不到定时任务主线程的request信息

解决方法：

在定义线程池之前加入两行代码，设置request子线程共享

// 子线程request共享
ServletRequestAttributes sra = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
RequestContextHolder.setRequestAttributes(sra, true);
// 定义线程池名称
ThreadFactory namedThreadFactory = new ThreadFactoryBuilder()
                .setNameFormat("my-pool-%d").build();
//创建线程池
ThreadPoolExecutor blockchainSavePool = new ThreadPoolExecutor(
                TimeUnit.MILLISECONDS,
                new LinkedBlockingQueue<Runnable>(10),
                namedThreadFactory);

				在开启新线程之前，将servletRequestAttributes设置为子线程共享
ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
//设置子线程共

                    不行啊，还是没用
                mybatis-plus 实现一对多查询，返回VO对象某个字段为List

                    这不行，分页直接gg

                    是mybatis-plus，不过一对多涉及多表结果映射的查询没法直接用service自带方法或者queryWapper实现，只能去xml里写映射关系
