日志拦截器

packagecom.vem.interceptor;

importorg.aspectj.lang.ProceedingJoinPoint;

importorg.aspectj.lang.annotation.Around;

importorg.aspectj.lang.annotation.Aspect;

importorg.aspectj.lang.annotation.Pointcut;

importorg.aspectj.lang.reflect.MethodSignature;

importorg.springframework.stereotype.Component;

importcom.vem.entity.BussAnnotation;

@Aspect

@Component

publicclassLogInterceptor{

@Pointcut("execution(*com.vem.service..*.*(..))")

publicvoidaApplogic(){

}

/**

*环绕通知用于拦截指定内容，记录用户的操作

*/

@Around(value="aApplogic()&&@annotation(annotation)&&args(object,..)",argNames="annotation,object")

publicvoidinterceptorApplogic(ProceedingJoinPointjoinPoint,

BussAnnotationannotation,Objectobject)throwsThrowable{

System.out.println("模块名称moduleName:"+annotation.moduleName());

System.out.println("操作名称option:"+annotation.option());

StringmethodName=joinPoint.getSignature().getName();

System.out.println("方法名methodName:"+methodName);

MethodSignaturemethodSignature=(MethodSignature)joinPoint.getSignature();

String[]strings=methodSignature.getParameterNames();

joinPoint.proceed();

Object[]arguments=joinPoint.getArgs();//获得参数列表

if(arguments.length<=0){

System.out.println(methodName+"方法没有参数");

}else{

for(inti=0;i<arguments.length;i++){

System.out.println(strings[i]+":"+arguments[i]+":");

}

}

}

}

自定义注解

@Retention(RetentionPolicy.RUNTIME)

@Target({ElementType.METHOD})

@Documented

public@interfaceBussAnnotation{

//模块名

StringmoduleName()default"";

//操作内容

Stringoption()default"";

}

接口实现

写在service

@BussAnnotation(moduleName="人员管理",option="添加用户")

publicvoidtestDemo1(PageDatapd)throwsException{

}

junit测试类

packagecom.vem.entity;

importjavax.annotation.Resource;

importorg.junit.Test;

importorg.junit.runner.RunWith;

importorg.springframework.test.context.ContextConfiguration;

importorg.springframework.test.context.junit4.SpringJUnit4ClassRunner;

importcom.vem.service.data.DemoService;

importcom.vem.util.PageData;

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(

{"classpath:spring/ApplicationContext.xml"

})

publicclassAopTest{

@Resource(name="demoService")

publicDemoServicedemoService;

@Test

publicvoidtestAopAddUser1(){

PageDatapd=newPageData();

pd.put("name","zhangzexing");

pd.put("age","21");

pd.put("passward","123456");

try{

demoService.testDemo2(pd);

}catch(Exceptione){

//TODOAuto-generatedcatchblock

e.printStackTrace();

}

}

}
