<bean id="testAspect" class="aspect.TestAspect"/>
</beans>Aspect的类
package aspect;import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;import test.User;
@Aspect
public class TestAspect {
@Before("execution(* test.TestBean1.*(..)) &&"+"args(user,..)")  
public void aspectTest(User user){
System.out.println("测试 aspect "+user.getCode());
}
}
TestBean1类
package test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;@Component("bean1")
public class TestBean1 {
@Autowired
private Bean11 bean11;
public String getString(User user){
System.out.println("bean1 执行了");
return "bean1";
}
public Bean11 getBean11() {

}
public void setBean11(Bean11 bean11) {
this.bean11 = bean11;
}

}User类

return code;
}
public void setCode(String code) {

System.out.println(bean1.getString(user));
}}输出结果：

   bean1
