Question

当我尝试使用Hibernate从AsyncUncaughtExceptionHandler（如果@Async方法中有任何异常将被触发）执行数据库操作时，我面临以下问题。

代码段：

CustomAsyncUncaughtExceptionHandler：

public class CustomAsyncUncaughtExceptionHandler implements AsyncUncaughtExceptionHandler {

private final Log logger = LogFactory.getLog(CustomAsyncUncaughtExceptionHandler.class);

@Autowired
private AuditService auditService;

@Override
public void handleUncaughtException(final Throwable ex, final Method method, final Object... params) {

    if (params[0] instanceof HttpServletRequest) {
        final HttpServletRequest request = (HttpServletRequest) params[0];
        this.auditService.auditAsyncException(ex.getMessage(), ex instanceof Exception
                ? (Exception) ex
                : null, request.getRemoteUser(), request.getRequestURI(), this.getMapOfParameters(request));
    }
    else {
        this.logger.error(String.format("Unexpected error occurred invoking async " + "method '%s'.", method), ex);
    }

}
}

auditAsyncException：

@Service
public class AuditServiceImpl implements AuditService {
private static final Logger LOG = 
LoggerFactory.getLogger(AuditServiceImpl.class);
@Autowired
private AuditDao auditDao;

@Override
@Transactional(propagation = Propagation.REQUIRES_NEW)
public ExceptionAudit auditAsyncException(final String message, final Exception ex, final String userid,
        final String requestUri, final Map<String, String> parameters) {

    LOG.debug("auditException");

    ExceptionSeverity severtiy = ExceptionSeverity.HIGH;

    final ExceptionAudit exceptionAudit =
            new ExceptionAudit(message, ex, userid, requestUri, severtiy, parameters, null);

    this.auditDao.saveAuditException(exceptionAudit);

    LOG.error(message, ex);
    return exceptionAudit;
}
}

错误消息：

ERROR [executor-1] o.s.s.a.AnnotationAsyncExecutionInterceptor.handleError(AsyncExecutionAspectSupport.java:300)| Exception handler for 
async method 'public sendSMSOrScheduleDelivery(javax.servlet.http.HttpServletRequest,java.lang.Long,java.lang.String,java.lang.Long,java.util.List<java.lang.String>,java.lang.String)' threw unexpected exception itself

有指针吗？

我建议遵循我的实施方式。

在AsyncUncaughtExceptionHandler的上下文中，无法连接到spring管理的bean /服务。不是我知道...
