1.在springMvc的xml配置文件中加入开启aop和扫描aop的配置

<!-- 把aop配置类加入bean容器中 -->
    <context:component-scan base-package="com.sinosoft.aop"></context:component-scan>
    <!-- 开启aop注解方式 -->
     <aop:aspectj-autoproxy/>

2.编写aop类

@Aspect
@Configuration
public class Logger {

    @Autowired
    private OperatorLogService service;
    @Autowired
    HttpServletRequest request;
    @Autowired
    HttpServletResponse response;

    @Pointcut("@within(org.springframework.stereotype.Controller) || @within(org.springframework.web.bind.annotation.RestController)")
    public void cutController() {
    }

    @Around("cutController()")
    public Object recordSysLog(ProceedingJoinPoint joinPoint) throws Throwable {
        OperatorLogDTO dto = new OperatorLogDTO();
        String flag = "Y";
        Object ob = null;
        String url = request.getRequestURI(); 
        //String url=request.getRequestURL().toString();
        int length = request.getContextPath().length();
        url = url.substring(length);
        UserInfo userInfo = CurrentUser.getCurrentUser();
        try {

            ob = joinPoint.proceed();

        } catch (Throwable throwable) {
            // 没个对数据库进行操作的方法中都存在try catch，因为这里存在这个问题存在了异常也无法执行异常通知（异常在之前就被处理了）
            // 解决方法：所有catch中都把异常抛出
            flag = "N";
            // 这里不抛出这个异常全局异常时捕获不到任何异常的，aop在全局异常前执行，所有只有抛出此异常全局异常才能获取到
            throw throwable;
        } finally {
        
            // 用户登录后才会执行
            if (userInfo != null) {
                dto.setOperateResult(flag);
                // 获取用户的code
                dto.setUserCode(userInfo.getUserCode());
                // 获取客户端ip
                dto.setOperatorIp(request.getRemoteHost());
                // 获取请求路径
                dto.setInterfaceValue(url);
                service.add(dto);
            }

        }

        return ob;
    }

}
