Spring整合CXF开发基于rest的服务

使用Spring整合CXF，开发rest的服务

一、服务端开发

1、创建Dynamic Web Project，具体略

2、创建pojo类

package com.xxx.cxf.pojo;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "student")
public class Student {

	private long id;
	private String name;

	public long getId() {
		return id;
	}

	public void setId(long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

3、创建服务接口

package com.xxx.cxf.service;

import javax.jws.WebService;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import com.xxx.cxf.pojo.Student;

@WebService
@Path("/student")
public interface StudentInterface {

	@GET
	@Produces(MediaType.APPLICATION_JSON)
	@Path("/query/{id}")
	public Student query(@PathParam("id")long id);
}

4、创建实现类

package com.xxx.cxf.service;

import com.xxx.cxf.pojo.Student;

public class StudentInterfaceImpl implements StudentInterface {

	@Override
	public Student query(long id) {
		
		Student student = new Student();
		student.setId(2);
		student.setName("hehe");
		return student;
	}

}

5、在Spring的配置文件中，发布服务

<?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:jaxws="http://cxf.apache.org/jaxws"
	xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:cxf="http://cxf.apache.org/core"
	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
				            http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
				            http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">
	<!-- <jaxrs:server发布REST的服务 ，对JAXRSServerFactoryBean类封装-->	
	<jaxrs:server address="/user">
		<jaxrs:serviceBeans>
			<ref bean="studentInterface"/>
		</jaxrs:serviceBeans>
	</jaxrs:server>
	
	<!-- 配置服务实现类 -->
	<bean name="studentInterface" class="com.xxx.cxf.service.StudentInterfaceImpl"/>
</beans>

6、配置web.xml

<?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_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>ws_2_cxf_spring_server</display-name>
  
  <!-- 设置spring的环境 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- 配置CXF的Servlet -->
  <servlet>
  	<servlet-name>CXF</servlet-name>
  	<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  	<servlet-name>CXF</servlet-name>
  	<url-pattern>/ws/*</url-pattern>
  </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>

7、部署到Tomcat，查看使用说明书

http://localhost:8080/zzzzz_cxf_spring_rest_server/ws/user?_wadl

二、客户端开发
