spring统一日志管理，切面（@Aspect），注解式日志管理

step1 开启切面编程

    <!-- 开启切面编程（通过配置织入@Aspectj切面 ）  -->
    <aop:aspectj-autoproxy/>

　　<aop:aspectj-autoproxy />有一个proxy-target-class属性，默认为false，表示使用jdk动态代理织入增强，当配为<aop:aspectj-autoproxy poxy-target-class="true"/>时，表示使用CGLib动态代理技术织入增强。不过即使proxy-target-class设置为false，如果目标类没有声明接口，则spring将自动使用CGLib动态代理。

step2 编写日志注解类

@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemLog {
    public String description() default "";
}

@Aspect
@Component
public class SystemLogAspect {

    @Pointcut("@annotation(com.tj.common.log.system.SystemLog)")
    public  void controllerAspect() {}  

    @Pointcut("@annotation(com.tj.common.log.system.SystemLog)")
    public  void serviceAspect() {} 

    @Pointcut("@annotation(com.tj.common.log.system.SystemLog)")
    public  void repositoryAspect() {} 

    @After("controllerAspect()")
    public void doBefore(JoinPoint joinPoint) {
        try {
            HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
            String ip = request.getRemoteAddr();
            String description = getControllerMethodDescription(joinPoint);
            Object obj = request.getSession().getAttribute("loginUser");
            LogUser user = new LogUser(null, null);
            /*对象obj中必须拥有属性account、userName*/
            BeanUtils.copyProperties(user, obj);
            if(StringUtils.isBlank(user.getAccount())){
                user = new LogUser("Anonymous", "匿名用户");
            }
        } catch (Exception e) {

        }
    } 

    @SuppressWarnings("rawtypes")
    private static String getControllerMethodDescription(JoinPoint joinPoint)  throws Exception {
        String targetName = joinPoint.getTarget().getClass().getName();
        String methodName = joinPoint.getSignature().getName();
        Object[] arguments = joinPoint.getArgs();
        Class targetClass = Class.forName(targetName);
        Method[] methods = targetClass.getMethods();
        String description = "";
        for (Method method : methods) {
            if (method.getName().equals(methodName)) {
                Class[] clazzs = method.getParameterTypes();
                if (clazzs.length == arguments.length) {
                    description = method.getAnnotation(SystemLog.class).description();
                    break;
                }
            }
        }
        return description;
    }
}

step2 日志记录

　　

@CrossOrigin(maxAge = 3600)
@RestController
@RequestMapping(value = "/cxOrders")
public class CxOrderResources {

    @SystemLog(description="查询订单列表操作")
    @RequestMapping( value="/showData", method = RequestMethod.GET)
    public ResponseEntity<String> showData()throws ApplicationRuntimeException {
        return new ResponseEntity<String>("", HttpStatus.OK);
    }

}
