Answer 1

我来晚了，但我遇到了same issue with RESTX，经过进一步调查，当 URL 包含解释为 JMX MBean 名称中的模式的字符（即* 和?）时，就会发生这种情况。实际上，当框架（在您的情况下为 spring boot）为此 URL 添加度量时，来自 Codahale Metrics 的 JMXReporter 依次尝试使用该名称注册一个 MBean，但由于该异常而失败（该消息不是很有帮助）。

source code for the JMX Repository 更能显示问题。

可能的解决方案：

• 将 Metrics 升级到 v3.1.0 或更高版本（名称从 codahale 指标更改为 dropwizard 指标），并注册您自己的 ObjectNameFactory 以解决此问题。这是the approach I've used in RESTX。
• 如果可以的话，至少为这个 URL 禁用 JMXReporter（我还没有检查过 Spring Boot 是否可以）
• 覆盖指标过滤器以转义导致问题的字符
