spring整合cxf入门案例

悠悠 2022-07-13 05:21 189阅读 0赞

spring是j2ee最重要的容器框架，cxf封装了webservice，使webservice的使用变的更加轻松，是解决异构系统交互问题的首选。spring整合cxf的demo分为如下几个步骤：  
1).新建web项目，建包分层  
2).引进spring管理各个类  
3).使用junit测试spring  
4).引进cxf，建cxf的service层，提供对外服务

下面开始具体的整合流程：  
开发环境：Myeclipse2014+tomcat8+jdk1.7+linux

1.到Apache官网下载cxf

2.新建web项目，建立各层包和xml文件  
项目的最终形态：

3.引进jar包  
将第一步下载后的cxf解压，在lib目录下，将所有jar包复制到项目中WEB-INF下的lib目录下。

4.填充基础的类

![这里写图片描述][SouthEast 2]

<1>PersonDao.java

package com.hsp.dao;
    
    import com.hsp.model.Person;
    
    public interface PersonDao { 
    
        public void savePerson(Person person);
    
    }

<2>PersonDaoImpl.java

package com.hsp.dao.impl;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import org.springframework.stereotype.Repository;
    
    import com.hsp.dao.PersonDao;
    import com.hsp.model.Person;
    @Repository("personDao")
    public class PersonDaoImpl implements PersonDao { 
    
        private List<Person> pList = new ArrayList<Person>();
    
        @Override
        public void savePerson(Person person) {
            pList.add(person);
            System.out.println(person.getName()+"加入组织，代号："+person.getId());
        }
    
    }

<3>Person.java

package com.hsp.model;
    
    public class Person {
    
        private Integer id;
        private String name;
        public Integer getId() {
            return id;
        }
        public void setId(Integer id) {
            this.id = id;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
    
    }

<4>PersonService.java

package com.hsp.service;
    
    import com.hsp.model.Person;
    
    public interface PersonService { 
    
        public void savePerson(Person person);
    
    }

<5>PersonServiceImpl.java

package com.hsp.service.impl;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import com.hsp.dao.PersonDao;
    import com.hsp.model.Person;
    import com.hsp.service.PersonService;
    @Service("personService")
    public class PersonServiceImpl implements PersonDao, PersonService { 
    
        @Autowired
        private PersonDao personDao;
    
        @Override
        public void savePerson(Person person) {
            personDao.savePerson(person);
        }
    
    }

5.引进spring

在src目录下建立beans.xml  
<1>beans.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:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    
    
            <context:component-scan base-package="com.hsp"></context:component-scan>
    
    </beans>

6.junit测试spring整合是否成功  
只要测试service的PersonService.java即可，选中PersonService.java，生成junit类，即生成PersonServiceTest.java

![这里写图片描述][SouthEast 3]

<1>PersonServiceTest.java

package com.hsp.test;
    
    import static org.junit.Assert.*;
    
    import org.junit.Before;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import com.hsp.model.Person;
    import com.hsp.service.PersonService;
    
    public class PersonServiceTest {
    
        ApplicationContext ctx;
    
        @Before
        public void setUp() throws Exception {
            ctx = new ClassPathXmlApplicationContext("beans.xml");
        }
    
        @Test
        public void testSavePerson() {
            PersonService ps = (PersonService)ctx.getBean("personService");
            Person p = new Person();
            p.setId(101);
            p.setName("楚留香");
            ps.savePerson(p);
        }
    }

若junit测试成功，则进行下一步，否则，调到正确为止。

8.建立webservice层  
在src下新建com.hsp.ws.service包和com.hsp.ws.service.impl包，用于对外发布的服务。

![这里写图片描述][SouthEast 4]

<1>PersonWSService.java

package com.hsp.ws.service;
    
    import javax.jws.WebService;
    
    import com.hsp.model.Person;
    
    @WebService
    public interface PersonWSService { 
    
        public void savePerson(Person person);
    
    }

<2>PersonWSServiceImpl.java

package com.hsp.ws.service.impl;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import com.hsp.dao.PersonDao;
    import com.hsp.model.Person;
    import com.hsp.ws.service.PersonWSService;
    @Service("personWSService")
    public class PersonWSServiceImpl implements PersonWSService, PersonDao { 
    
        @Autowired
        private PersonDao personDao;
    
        @Override
        public void savePerson(Person person) {
            personDao.savePerson(person);
        }
    
    }

9.引进cxf

在WEB-INF目录下建立cxf-servlet.xml文件。  
<1>cxf-servlet.xml：

10.配置web.xml  
在WEB-INF目录下建立web.xml文件。  
<1>web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:beans.xml, classpath*:cxf-servlet.xml</param-value>
        </context-param>
    
    
        <servlet>
            <servlet-name>cxf-servlet</servlet-name>
            <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        </servlet>
        <servlet-mapping>
            <servlet-name>cxf-servlet</servlet-name>
            <url-pattern>/services/*</url-pattern>
        </servlet-mapping>
    </web-app>

11.测试cxf服务端是否成功  
在浏览器输入

http://localhost:8080/cxf_server/services

若出现下图则代表成功:

![这里写图片描述][SouthEast 5]

点击页面的链接会出现wsdl文档：

![这里写图片描述][SouthEast 6]

至此，spring整合cxf完成。

12.新建客户端项目调用webservice服务  
<1>找一个空白的目录，在终端利用wsimport生成webservice的类。格式为：wsimport+-s+存放路径+wsdl文档链接

![这里写图片描述][SouthEast 7]

<2>将生成的代码复制到新建客户端中，选中的包就是生成的webservice代码

![这里写图片描述][SouthEast 8]

<3>新建client调用webservice  
Client.java：

package com.hsp.client;
    
    import com.hsp.ws.service.Person;
    import com.hsp.ws.service.PersonWSService;
    import com.hsp.ws.service.PersonWSServiceService;
    
    public class Client {
    
        public static void main(String[] args) {
            //创建服务访问点的集合
            PersonWSServiceService pss = new PersonWSServiceService();
            //获得服务访问点绑定的类，getPersonServicePort
            PersonWSService ps = pss.getPersonWSServicePort();
            //调用服务
            Person p = new Person();
            p.setId(102);
            p.setName("孟星魂");
            ps.savePerson(p);
        }
    
    }

如果没报错就成功了！
