CXFRS和Spring整合服务器端配置

创建一个maven war项目

1.导jar包

<dependencies>
        <!-- cxf 进行rs开发 必须导入  -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxrs</artifactId>
            <version>3.0.1</version>
        </dependency>

        <!-- 日志引入  -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.12</version>
        </dependency>

        <!-- 客户端,该项目可能也需要从其他项目请求数据，所以导入客户端jar包 -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-rs-client</artifactId>
            <version>3.0.1</version>
        </dependency>

        <!-- json数据需要使用的jar包 -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-rs-extension-providers</artifactId>
            <version>3.0.1</version>
        </dependency>

        <!-- 转换json工具包，被extension providers 依赖 -->
        <dependency>
            <groupId>org.codehaus.jettison</groupId>
            <artifactId>jettison</artifactId>
            <version>1.3.7</version>
        </dependency>

        <!-- spring 核心 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.1.7.RELEASE</version>
        </dependency>

        <!-- spring web集成 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.1.7.RELEASE</version>
        </dependency>

        <!-- spring 整合junit  -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>4.1.7.RELEASE</version>
        </dependency>

        <!-- junit 开发包 -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
  </dependencies>
  <build>   <!--插件设置该项目的接口，避免接口冲突 -->
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>tomcat-maven-plugin</artifactId>
            <version>1.1</version>
            <configuration>
                <port>9996</port>
            </configuration>
        </plugin>
    </plugins>
  </build>

2.web.xml配置(spring,cxfServlet)
注意 需要自己导入WEB_INF文件夹(主要是web.xml文件)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">

    <!-- spring配置文件位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- spring核心监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>CXFService</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFService</servlet-name>
        <url-pattern>/services/*</url-pattern>   <!-- 配置文件中配置servlet就是配置访问路径来访问对应servlet中的service()方法  -->
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

</web-app>

3.applicationContext.xml配置

<?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:jaxrs="http://cxf.apache.org/jaxrs"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">

    <!-- 
                                          项目名          servlet    address    方法path
        address 发布服务地址  http://localhost:9996/cxfrs_Spring/services/userService/user
        servicesBeans 服务实现类 
     -->
    <jaxrs:server id="userService" address="/userService" >
        <jaxrs:serviceBeans>
            <bean class="cn.itcast.cxf.service.UserServiceImpl" />
        </jaxrs:serviceBeans>
        <jaxrs:inInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingInInterceptor" />
        </jaxrs:inInterceptors>
        <jaxrs:outInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
        </jaxrs:outInterceptors>
    </jaxrs:server>

</beans>

5.其他配置文件
log4j.properties

6.项目代码

/**
 * 服务相关实体类
 */
package com.itheima.domain;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="User")
public class User {
    private Integer id;
    private String name;
    private String sex;

    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;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }


    @Override
    public String toString() {
        return "User [id=" + id + ", name=" + name + ", sex=" + sex + "]";
    }


}

服务接口和实现类

package com.itheima.service;

import java.util.List;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;

import com.itheima.domain.User;

public interface IUserService {
    @GET
    @Path("/user")
    @Produces({ "application/xml", "application/json" })
    public List<User> findAllUser();

    @GET
    @Path("/user/{id}")
    @Consumes({ "application/xml", "application/json" })
    @Produces({ "application/xml", "application/json" })
    public User findUserById(@PathParam("id") int id);

}

package com.itheima.service.impl;

import java.util.ArrayList;
import java.util.List;

import com.itheima.domain.User;
import com.itheima.service.IUserService;

public class UserServiceImpl implements IUserService{

    public List<User> findAllUser() {
        List<User> users = new ArrayList<User>();
        User user01 = new User();
        user01.setId(1);
        user01.setName("张三");
        user01.setSex("男");
        users.add(user01);

        User user02 = new User();
        user02.setId(2);
        user02.setName("冷艳");
        user02.setSex("女");
        users.add(user02);
        return users;
    }

    public User findUserById(int id) {
        User user01 = new User();
        user01.setId(1);
        user01.setName("张三");
        user01.setSex("男");
        return user01;
    }

}

6.测试

7.总结
服务器端 CXF-RS开发 相关步骤
1.导jar包
2.web.xml中配置CXFServlet( 该servlet类，由CXF提供）
编写服务 实体类 接口和实现类
3.applicationContext.xml中配置 address和服务实现类
