Spring-boot 配置Aop获取controller里的request中的参数以及其返回值

首先在你的Maven的pom文件里加入aop的依赖：

  <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-aop</artifactId>
  </dependency>

在spring boot里面一切配置都是很简单的，下面为我所有被请求到的controller加上Aop的功能吧，看码：

package me.jiaobuchong.admin.config;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import com.google.gson.Gson;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;;

/**
 * Created by jiaobuchong on 12/23/15.
 */
@Aspect   //定义一个切面
@Configuration
public class LogRecordAspect {
private static final Logger logger = LoggerFactory.getLogger(UserInterceptor.class);

    // 定义切点Pointcut
    @Pointcut("execution(* com.jiaobuchong.web.*Controller.*(..))")
    public void excudeService() {
    }

    @Around("excudeService()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        RequestAttributes ra = RequestContextHolder.getRequestAttributes();
        ServletRequestAttributes sra = (ServletRequestAttributes) ra;
        HttpServletRequest request = sra.getRequest();

        String url = request.getRequestURL().toString();
        String method = request.getMethod();
        String uri = request.getRequestURI();
        String queryString = request.getQueryString();
        logger.info("请求开始, 各个参数, url: {}, method: {}, uri: {}, params: {}", url, method, uri, queryString);

        // result的值就是被拦截方法的返回值
        Object result = pjp.proceed();
        Gson gson = new Gson();
        logger.info("请求结束，controller的返回值是 " + gson.toJson(result));
        return result;
    }
}

只要加上上面这个类，Aop就算配置好了，不信，去访问以下你的Controller试试。对比以前配置aop的方式(xml文件)，现在的配置都到Java代码里来了，@Configuration这个Annotation就是JavaConfig的典型代表，Spring boot在启动时会会自动去加载这些配置，实现相应的配置功能。这个简单的小例子算是抛砖引玉吧，我也是参考别人的博客，更多细节，查看下面的博客：
