面向切面编程之登录日志

AOP的依赖：

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

获取当前所在城市的依赖：

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>geolite2-databases</artifactId>
    <version>20151029</version>
</dependency>

切面类的代码：

@Component
@Aspect //切面
public class LogininfoAop {
    @Autowired
    private LogininfoFeign logininfoFeign;
//    @Before() 前置通知。
//    @After() 后置通知 finally
//      @AfterReturning 返回通知。 没有异常。
//      @AfterThrowing 异常通知 catch
    @AfterReturning(value = "execution(* com.car.sso.service.impl.*.*(..))")
    public void loginAfter(JoinPoint joinPoint){
          //添加登陆成功的日志。
        Logininfo logininfo=new Logininfo();
        //设置登陆的用户名
        LoginVo loginVo= (LoginVo) joinPoint.getArgs()[0];
        logininfo.setLoginName(loginVo.getUsername());
        //设置登陆者的ip
        //获取请求对象
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        logininfo.setIpaddr(request.getRemoteAddr());
