java - 如何为@RestController 启用日志记录？

Question

如何在使用 Spring 编写的 REST 服务上自动记录任何传入的 GET url 请求？

@RestController
public class MyRest {
    @RequestMapping(method = RequestMethod.GET,
            produces = MediaType.APPLICATION_XML_VALUE)
    @ResponseBody
    public ComplexRsp test() {
        //...
    }
}

我已经将 cxf 用于 soap，其中日志记录与使用 @InInterceptors、@OutInterceptors 注释 web 服务一样简单。

Spring 有没有类似的东西可以休息？

如果您使用 spring security，您可以只启用 log4j org.springframework.security，但它非常冗长:

<category name="org.springframework.security">
   <priority value="ALL" />
</category>

或者你可以实现一个拦截器:

public class LoggerInterceptor extends HandlerInterceptorAdapter {    
    private static final Logger logger = LoggerFactory.getLogger(LoggerInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        logger.info("pre hangle URI: " + request.getRequestURI());

        return super.preHandle(request, response, handler);
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        logger.info("post hangle URI: " + request.getRequestURI());

        super.afterCompletion(request, response, handler, ex);
    }    
}

applicationContext.xml

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/**" />
        <bean class="com.mycompany.LoggerInterceptor"></bean>
    </mvc:interceptor>
</mvc:interceptors>
