一、配置文件方式
1、配置applicationContext.xml,
<bean id="logAopBean" class="com.demo.common.aop.LogAop"></bean>
<aop:config>
<aop:aspect id="logAspect" ref="logAopBean">
<aop:pointcut expression="execution(* com.demo..*(..))" id="allMethod"/>
<aop:before method="before" pointcut-ref="allMethod" />
<aop:after-throwing method="afterThrowing" pointcut-ref="allMethod" />
<aop:after-returning method="afterReturn" pointcut-ref="allMethod" />
<aop:after method="after" pointcut-ref="allMethod" />
</aop:aspect>
</aop:config>
2、日志处理类,
/**
* LogAop.java
*
* Shanghai NTT DATA Synergy Software Co., Ltd. All Rights Reserved.
* @author wyl
* @date 2016-10-18
*/
package com.demo.common.aop;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
/**
* @author wyl
* @Description TODO
* @date 2016-10-18
*
*/
public class LogAop {
public void before(JoinPoint call){
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println("开始执行:"+className+"."+methodName+"()方法...");
}
public void afterThrowing(JoinPoint call){
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println(className+"."+methodName+"()方法抛出了异常...");
}
public void afterReturn(JoinPoint call){
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println(className+"."+methodName+"()方法正常执行结束...");
}
public void after(JoinPoint call){
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println(className+"."+methodName+"()最终执行步骤(finally)...");
}
/*//用来做环绕通知的方法可以第一个参数定义为org.aspectj.lang.ProceedingJoinPoint类型
public Object doAround(ProceedingJoinPoint call) throws Throwable {
Object result = null;
this.before(call);//相当于前置通知
try {
result = call.proceed();
this.afterReturn(call); //相当于后置通知
} catch (Throwable e) {
this.afterThrowing(call); //相当于异常抛出后通知
throw e;
}finally{
this.after(call); //相当于最终通知
}
return result;
}*/
}
二、注解方式
1、配置applicationContext.xml,
<bean id="logAspectBean" class="com.demo.common.aop.LogAnnotationAspect"></bean>
<aop:aspectj-autoproxy/>
2、日志处理类,
/**
* LogAnnotationAspect.java
*
* Shanghai NTT DATA Synergy Software Co., Ltd. All Rights Reserved.
* @author wyl
* @date 2016-10-18
*/
package com.demo.common.aop;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
/**
* @author wyl
* @Description TODO
* @date 2016-10-18
*
*/
@Aspect //定义切面类
public class LogAnnotationAspect {
@SuppressWarnings("unused")
//定义切入点,提供一个方法,这个方法的名字就是改切入点的id
@Pointcut("execution(* com.demo..*(..))")
private void allMethod(){}
//针对指定的切入点表达式选择的切入点应用前置通知
@Before("allMethod()")
public void before(JoinPoint call) {
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println("开始执行:"+className+"."+methodName+"()方法...");
}
//访问命名切入点来应用后置通知
@AfterReturning("allMethod()")
public void afterReturn(JoinPoint call) {
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println(className+"."+methodName+"()方法正常执行结束...");
}
//应用最终通知
@After("allMethod()")
public void after(JoinPoint call) {
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println(className+"."+methodName+"()最终执行步骤(finally)...");
}
//应用异常抛出后通知
@AfterThrowing("allMethod()")
public void afterThrowing(JoinPoint call) {
String className = call.getTarget().getClass().getName();
String methodName = call.getSignature().getName();
System.out.println(className+"."+methodName+"()方法抛出了异常...");
}
//应用周围通知
//@Around("allMethod()")
public Object doAround(ProceedingJoinPoint call) throws Throwable{
Object result = null;
this.before(call);//相当于前置通知
try {
result = call.proceed();
this.afterReturn(call); //相当于后置通知
} catch (Throwable e) {
this.afterThrowing(call); //相当于异常抛出后通知
throw e;
}finally{
this.after(call); //相当于最终通知
}
return result;
}
}
