报错

(报错解决)Exception encountered during context initialization

警告: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testDao' defined in class path resource [aspectj/xml/applicationContext.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#1': Cannot create inner bean '(inner bean)#57175e74' of type [org.springframework.aop.aspectj.AspectJAfterReturningAdvice] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#57175e74': Cannot create inner bean '(inner bean)#7bb58ca3' of type [org.springframework.aop.config.MethodLocatingFactoryBean] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#7bb58ca3': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Unable to locate method [afterReturning] on bean [myAspect]

检查

拖到最右边查看报错
(报错解决)Exception encountered during context initialization

Unable to locate method [afterReturning] on bean [myAspect]

就是说bean实例myAspect中的方法afterReturning有问题。

检查MyAspect.java中的方法afterReturning。与applicationContext.xml对应位置进行比较。
 
 
发现是MyAspect.java中的方法afterReturning拼写有问题(多写了个n)。与applicationContext.xml对应不上。

(报错解决)Exception encountered during context initialization

解决

将MyAspect.java中的方法afterReturnning改为afterReturning。与applicationContext.xml中的afterReturning对应上。

总结

1.查看eclipse报错部分的最上面的最右边
2.检查xml文件以及报错提示的bean对应java文件。

public Object around(ProceedingJoinPoint pjp) throws Throwable{
//开始
System.out.println("环绕开始:执行目标方法前,模拟开始事务");
//执行当前目标方法
Object obj = pjp.proceed();
//结束
System.out.println("环绕结束:执行目标方法后,模拟关闭事务");

} //异常通知

System.out.println("异常通知:"+"程序执行异常"+e.getMessage());
} //后置(最终)通知
public void after(){
System.out.println("最终通知:模拟释放资源");
}
}
XMLAspectJTest.java
package aspectj.xml;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; import dynamic.jdk.TestDao; public class XMLAspectJTest {
//在主方法中使用Spring容器获取代理对象,并执行目标方法
public static void main(String[] args) {

//从容器中获取增强后的目标对象

//执行方法
testDaoAdvice.save();
/*

} }

package dynamic.jdk;

TestDao.java
package dynamic.jdk;

public interface TestDao {
public void save();
public void modify();
public void delete();
}
TestDaoImpl.java
package dynamic.jdk;

//该实现类作为目标类,在代理类中对实现类的方法进行增强处理
public class TestDaoImpl implements TestDao { @Override
public void save() {
System.out.println("保存");
} @Override
public void modify() {
System.out.println("修改");
} @Override
public void delete() {
System.out.println("删除");
}
}

运行结果(运行XMLAspectJTest.java)
