最近升级了公司框架，然后发现错误日志一直在刷。

调查过程

因为 pinpoint jar 包只放在了容器里，所以本地复现麻烦些，所以准备用 arthas 定位下原因。

背景

多语言的设置在测试环境可以正常展示，但是在生产环境却无法展示。

确认代码版本

生产区

背景

还是老问题，线上接口多次请求数据不一致。

过程

通过本地程序并发测试，本地无法复现。

并发测试线上接口，可以复现。

查看日志，发现日志打印不全。不要使用 log.error(“xxxx:{}”, e.getMessage())

修改日志, 打出异常堆栈。

1

log.error("xxxx", e)

发现在并发中，调用会报空指针异常。

1

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

当前线程是没有设置的，但是代码里会调用继承的, 这里本地并发测试无法复现，但是线上会出现。

1

5
6
7
8

	@Nullable
	public static RequestAttributes getRequestAttributes() {
		RequestAttributes attributes = requestAttributesHolder.get();
		if (attributes == null) {
			attributes = inheritableRequestAttributesHolder.get();
		}
		return attributes;
	}

这个内部的原因暂时还未知，需要了解下继承 threadLoacal 和内部线程流转。

背景

最近发现一个 bug, 有时返回数据，有时返回null。

过程

初步调查发现，应该是报错，但是异常被吞了，导致返回 null。 本地调用无法复现，推测可能是并发场景下的报错。

于是通过 postman 来并发调用接口，果然复现了异常。

Request.notifyAttributeAssigned 时由于 context 对象为 null 因此异常。
