看报错集中在LoggerWrapper,这是一个自己封装的Logger类，可以保存msgId等，需要每次打印日志都要打印出来的东西，避免，每次都需要在后面加上这样的参数。
看使用方法
@ServiceImplementation
public class ProvisioningServiceImpl implements ProvisioningService {
private static final Logger LOGGER = LoggerFactory.getLogger(ProvisioningServiceImpl.class);
private LoggerWrapper loggerWapper;
@ServiceSetter
private CatsProxy userIndexService;
@Override
public ProvisioningResult process(RequestExtArgs extArgs) {
ProvisioningResult result = new ProvisioningResult();
result.setRespCode(200);
result.setRespDesc("success!");
ProvisioningArgs provisioningArgs = BeanUtil.argsBuild(extArgs.getBody(), ProvisioningArgs.class, extArgs.isBodyJson());
loggerWapper = new LoggerWrapper(xxx
ProvisioningServiceImpl 是对于service的一个单例，会在服务启动时初始化
分析：每个线程都会访问单例的ProvisioningServiceImpl ，每次都会给全局的loggerWapper new一个新的对象，压力上来时，jvm运行的时候总是进行指针的切换
解决方法
- 1.LoggerWrapper作为一个局部变量每次访问LoggerWrapper的时候都重新new一个.
- 2.可使用ThreadLocal，但要注意remove
