LogsService

LogsDao

自定義注解SystemControllerLog

package com.vrms.app.aop;import java.lang.annotation.*;@Target({ElementType.PARAMETER, ElementType.METHOD})//作用在參數(shù)和方法上 @Retention(RetentionPolicy.RUNTIME)//運(yùn)行時(shí)注解 @Documented//表明這個(gè)注解應(yīng)該被 javadoc工具記錄 public @interface SystemControllerLog {String description() default ""; }

SystemLogAspect

package com.vrms.app.aop;import com.vrms.app.entity.Logs; import com.vrms.app.service.LogsService; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Component; import org.springframework.web.context.request.RequestContextHolder; import org.springframework.web.context.request.ServletRequestAttributes;import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import java.lang.reflect.Method; import java.text.SimpleDateFormat; import java.util.Date;@Aspect @Component public class SystemLogAspect {private static final Logger logger = LoggerFactory.getLogger(SystemLogAspect.class);@Resourceprivate LogsService logsService;//Controller層切點(diǎn)@Pointcut("@annotation(SystemControllerLog)")public void controllerAspect() {}@Before("controllerAspect()")public void doBefore(JoinPoint joinPoint) {HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();try {Logs logs = new Logs();logs.setMethods((joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName()));logs.setDdesc(getControllerMethodDescription(joinPoint));logs.setIp(request.getRemoteAddr()); //獲得訪問IP地址記錄到日志的IP屬性中logs.setOptime(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));if(logsService.save(logs)){System.out.println("日志添加成功");}else{System.out.println("日志添加失敗");}} catch (Exception e) {//記錄本地異常日志logger.error("==前置通知異常==");logger.error("異常信息：{}", e.getMessage());}}/*** @Description 獲取注解中對方法的描述信息 用于Controller層注解*/public static String getControllerMethodDescription(JoinPoint joinPoint) throws Exception {String targetName = joinPoint.getTarget().getClass().getName();String methodName = joinPoint.getSignature().getName();//目標(biāo)方法名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(SystemControllerLog.class).description();break;}}}return description;}}

獲取注解中對方法的描述信息其他方式

/*** @Description 獲取注解中對方法的描述信息 用于Controller層注解 */ public static String getControllerMethodDescription(JoinPoint joinPoint) {MethodSignature methodSignature =(MethodSignature) joinPoint.getSignature();SystemLog systemLog = methodSignature.getMethod ().getAnnotation(SystemLog.class);return systemLog.description(); }

獲取注解中對方法的描述信息其他方式（環(huán)繞通知中參數(shù)為ProceedingJoinPoint）

/*** @Description 獲取注解中對方法的描述信息 用于Controller層注解 （環(huán)繞通知參數(shù)為 ProceedingJoinPoint）*/ public static String getControllerMethodDescription(ProceedingJoinPoint joinPoint) {MethodSignature methodSignature =(MethodSignature) joinPoint.getSignature();SystemLog systemLog = methodSignature.getMethod ().getAnnotation(SystemLog.class);return systemLog.description(); }
