java - Spring AOP - 异常 : org. springframework.beans.factory.BeanDefinitionStoreException:

Question

我使用 Eclipse 和 Java8_40。我从带有 AOP 的 Spring 框架开始(来自 http://www.tutorialspoint.com/spring/aop_with_spring.htm )，并且 Beans.xml(?) 遇到一些问题。我认为我创建的示例是正确的，但它崩溃并显示异常。

我在 CLASSPATH 中有: Apache *.jars

• commons-logging-1.2.jar
• commons-logging-1.2-javadoc.jar

Spring *.jars

• spring-aop-4.1.5.RELEASE.jar
• spring-beans-4.1.5.RELEASE.jar
• spring-context-4.1.5.RELEASE.jar
• spring-aspects-4.1.5.RELEASE.jar
• spring-context-support-4.1.5.RELEASE.jar
• spring-core-4.1.5.RELEASE.jar
• spring-web-4.1.5.RELEASE.jar
• spring-webmvc-4.1.5.RELEASE.jar
• spring-expression-4.1.5.RELEASE.jar

AOP *.jar

• aspectjrt-1.8.5.jar
• aspectjweaver-1.8.5.jar
• aspectj-1.8.5.jar

程序客户端

package spring.program;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import spring.aop.trida.Student;
public class ProgramAOP1 {
    @SuppressWarnings("resource")
    public static void main(String [] args){
        System.out.println("Start Programu");
        ApplicationContext context =  new ClassPathXmlApplicationContext("Beans.xml");
        Student student = (Student) context.getBean("student");
        student.getName();
        student.getAge();
        System.out.println("Konec Programu");   }
}

Spring Bean AOP 类:

package spring.beanAOP;
public class BeanAOP {
    public void beforeAdvice(){
        System.out.println("Going to setup student profile.");  }
    public void afterAdvice(){
        System.out.println("Student profile has been setup.");  }
    public void afterReturningAdvice(Object retVal){
        System.out.println("Returning:" + retVal.toString() );  }
    public void AfterThrowingAdvice(IllegalArgumentException ex){
        System.out.println("There has been an exception: " + ex.toString());    }   
}

POJO 类:

package spring.aop.trida;
public class Student {
    private Integer age;
    private String name;
    public void setAge(Integer age) {
        this.age = age; }
    public Integer getAge() {
        System.out.println("Age : " + age );
        return age; }
    public void setName(String name) {
        this.name = name;   }
    public String getName() {
        System.out.println("Name : " + name );
        return name;    }
    public void printThrowException(){
        System.out.println("Exception raised"); 
        throw new IllegalArgumentException();   }
}
