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); } }
