可以稳定重现 复现手段
-------------------------------------------------------
jmeter+微服务A
微服务A发送请求给微服务B,且环境没有微服务B,然后用jmeter发送大量请求给微服务B 请求如下 无特殊之处
```
@GetMapping("/asyncSayHello/{name}")
public String asyncSayHello(@PathVariable("name") String name) {
cseAsyncRestTemplate.getForEntity("cse://TOF-provider/provider/tomcat/hello/" + name, String.class);
return null;
}
```
通过visualVM观察metaspace如下图
虽然能看到gc回收 单如果我将metaspace大小设置较小 很容易oom
