Springboot自定义注解+AOP实现日志管理

前言

在写Aurora这个项目之前,我是通过拦截器去记录用户操作日志,而这里讲解如何使用AOP配合自定义注解去实现用户日志记录,使用拦截器的方式,下一章贴出

导入依赖

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

部分配置文件

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/log
    username: root
    password: 123456

  jpa:
    hibernate:
      ddl-auto: update

自定义log注解

定义一个方法级别的@Log注解,用于标注需要监控的方法:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {
	String value() default "";
}

创建实体类

创建 repository @Repository public interface SysLogRepo extends JpaRepository<SysLog,Long>{ }

切面和切点

定义一个LogAspect类,使用@Aspect标注让其成为一个切面,切点为使用@Log注解标注的方法,使用@Around环绕通知,部门工具代码,这里就不贴出了,可以到源码中查看

@Slf4j
@Aspect
@Component
public class LogAspect {

	@Autowired
	private SysLogRepo sysLogRepo;

	@Pointcut("@annotation(me.zhengjie.annotation.Log)")
	public void pointcut() {
	}

    @Around("pointcut()")
    public Object around(ProceedingJoinPoint point){
        Object result = null;
        long beginTime = System.currentTimeMillis();
        try {
            // 执行方法
            result = point.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        // 执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;

        //保存日志
        saveLog(point, time);
        return result;
    }

    public void saveLog(ProceedingJoinPoint joinPoint, long time){
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        SysLog sysLog = new SysLog();
        Log logAnnotation = method.getAnnotation(Log.class);
        if (logAnnotation != null) {
            // 注解上的描述
            sysLog.setOperation(logAnnotation.value());
        }
        // 请求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        String username = null;
        sysLog.setMethod(className + "." + methodName + "()");
        // 请求的方法参数值
        Object[] args = joinPoint.getArgs();
        // 请求的方法参数名称
        LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();
        String[] paramNames = u.getParameterNames(method);
        if (args != null && paramNames != null) {
            String params = "";
            for (int i = 0; i < args.length; i++) {
                params += "  " + paramNames[i] + ": " + args[i];
            }
            sysLog.setParams(params);
        }
        // 获取request
        HttpServletRequest request = HttpContextUtils.getHttpServletRequest();

        // 设置IP地址
        sysLog.setIp(AddressUtils.getIpAddr(request));
        sysLog.setLocation(AddressUtils.getCityInfo(sysLog.getIp()));

        //模拟一个用户名
        sysLog.setUsername("admin");
        sysLog.setTime((int) time);
        sysLogRepo.save(sysLog);
    }
}

项目结构如下

测试 编写TestController

@RestController
public class TestController {

    @Autowired
    private SysLogRepo sysLogRepo;

    @Log("记录测试")
    @GetMapping(value = "/test")
    public String test1(String test){

        return test;
    }

    @GetMapping(value = "/list")
    public ModelAndView list(Model model){

        List<SysLog> sysLogs = sysLogRepo.findAll();
        model.addAttribute("sysLogs",sysLogs);

        return new ModelAndView("/index");
    }
}
