如何为 jax-rs 编写 spring AOP

Question

我是 spring AOP 的初学者。我的要求是在 invokeTestServer 方法之前登录 execution.Please 在下面找到我的代码：

应用-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:oxm="http://www.springframework.org/schema/oxm"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
                        http://www.springframework.org/schema/beans 
                        http://www.springframework.org/schema/beans/spring-beans.xsd
                        http://www.springframework.org/schema/mvc 
                        http://www.springframework.org/schema/mvc/spring-mvc.xsd
                        http://www.springframework.org/schema/util 
                        http://www.springframework.org/schema/util/spring-util.xsd
                        http://www.springframework.org/schema/context 
                        http://www.springframework.org/schema/context/spring-context.xsd
                        http://www.springframework.org/schema/aop
                        http://www.springframework.org/schema/aop/spring-aop.xsd
                        http://www.springframework.org/schema/oxm 
                        http://www.springframework.org/schema/oxm/spring-oxm.xsd
                        http://www.springframework.org/schema/tx
                        http://www.springframework.org/schema/tx/spring-tx.xsd">

    <aop:aspectj-autoproxy expose-proxy="true" />

    <context:component-scan base-package="mypackage.service" />

    <bean id="loggingAspect" class="mypackage.spring.InputAcceptorAspect" />

</beans>

在尝试将 AOP 与 jax-rs 集成时，我没有任何要初始化的特定 bean

请在下面找到我的组件

package mypackage.service;

@Component
public class FirstProcess {

    public Response invokeTestServer() throws TestServerException{
            //Logic
        return response;
    }
}

我的长相如下包裹 mypackage.spring;

@看点

public class InputAcceptorAspect {

    @Before("execution(*mypackage.service.invokeTestServer(..))")
    public void logBeforeInvokingTestServer(JoinPoint joinpoint){
        logger.error("TestServer got invoked");
        System.out.println("TestServer got invoked");
    }
}

我正在尝试使用以下主要内容进行测试 class

package mypackage.spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import mypackage.service.FirstProcess;

    public class TestAOP {

        public static void main(String args[])
        {
            ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");
            FirstProcess manager = context.getBean(FirstProcess.class);
            manager.invokeTestServer();
        }
    }

在执行上述操作时出现异常，无法创建文件中定义的 bean FirstProcess..

如有任何帮助，我们将不胜感激。

Answer 1

在 class FirstProcess.java 中，您正在尝试创建带有注释的 bean，但注释配置不存在于配置中。在 application-context.xml 文件中添加此标记以使用注释配置

创建 bean
