ThreadLocal，很多地方叫做线程本地变量，也有些地方叫做线程本地存储，其实意思差不多。可能很多朋友都知道ThreadLocal为变量在每个线程中都创建了一个副本，那么每个线程可以访问自己内部的副本变量

最后在ResponseBodyAdvice 的实现类中记录操作日志
public class LogResponseBodyAdvice implements ResponseBodyAdvice<ResultDTO> {

@Autowired

@Override
public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {

PlatformLog platformLog = PlatformLog.getPlatformLog();
if (platformLog==null){
return body;
}
try {
platformLog.setResultJson(mapper.writeValueAsString(body));
platformLog.setDataCode(""+body.getCode());
PlatformLog.removePlatformLog();
platformLogService.insert(platformLog);
} catch (Exception e) {
e.printStackTrace();
PlatformLog.removePlatformLog();
log.error("err method: wsLogResponseBodyAdvice.beforeBodyWrite, Exception ", e);
return body;
}
return body;

}
