java - Java获取线程ID的方法

Question

我可以如下指定 log4j 格式化程序以在 spring mvc 应用程序中打印当前线程 id

log4j.appender.FILE.layout.ConversionPattern=%d{ISO8601} %p %t %c - %m%n

如何以编程方式在我的 spring 应用程序中获取当前线程 ID。更准确地说，我想在拦截 Controller 方法的方面获取当前线程 ID。我的方面如下:

@Configurable
@Aspect
public class TimingAspect {

    @Autowired
    private HttpServletRequest httpServletRequest;

    //Generic performance logger for any mothod
    private Object logPerfomanceInfo(ProceedingJoinPoint joinPoint) {
       // do something with thread id
       // do something with httprequest
        ...
    }

    // Performance info for API calls
    @Around("execution(* package.controller.*.*(..))")
    public Object logAroundApis(ProceedingJoinPoint joinPoint) throws Throwable {
        return logPerfomanceInfo(joinPoint);
    }
}
