我正在尝试使用 Spring 3.1 运行基于 @AspectJ 的 AOP，但无法正确配置切入点切入点和建议方法是：

切入点：

@Pointcut("execution(* point.*.*(..))")
public void selectAll() {}

咨询后：

@After("selectAll()")
public void afterAdvice() {
    System.out.println("profile has been setup.");
}

之前的建议：

@Before("selectAll()")
public void beforeAdvice() {
    System.out.println("Going to setup profile.");
}

＆运行主程序我得到了异常：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'student' defined in class path resource [spring.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut selectAll

at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:291)
at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:193)

虽然当我在 beforeAdvice() 和 afterAdvice() 方法中给出切入点表达式时，删除 PointCuts 方法一切正常

@Before("execution(* point.*.*(..))")
public void beforeAdvice() {
    System.out.println("Going to setup profile.");
}

 @After("execution(* point.*.*(..))")
public void afterAdvice() {
    System.out.println("profile has been setup.");
}

我正在尝试将切入点应用于 Student 类的方法：

package point;

 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();
}
 }

解决了问题：创建 bean 时的问题是由于旧 jars

更换的罐子：

 aopalliance-1.0.jar
 asm-3.3.1.jar
 aspectj-1.7.1.jar
 aspectjrt-1.6.8.jar
 aspectjtools-1.5.4.jar
 aspectjweaver-1.6.2.jar
 cglib-2.2.2.jar

和

aopalliance-1.0.jar
asm-3.3.1.jar
aspectj-1.7.1.jar
aspectjrt-1.7.0.jar
aspectjweaver-1.7.0.jar
cglib-2.2.2.jar
