JAX-RS 和 Spring 整合开发步骤

1.建立maven web工程
2.建立坐标,在pom.xml中导入需要依赖的jar包

完整的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd";>;

<groupId>cn.itcast.maven</groupId>

<artifactId>cxf_rs_spring</artifactId>

<version>0.0.1-SNAPSHOT</version>

<name>cxf_rs_spring</name>

<groupId>org.apache.cxf</groupId>

<artifactId>cxf-rt-frontend-jaxrs</artifactId>

</dependency>

</dependency>

<groupId>org.apache.cxf</groupId>

<artifactId>cxf-rt-rs-client</artifactId>

</dependency>

<groupId>org.apache.cxf</groupId>

<artifactId>cxf-rt-rs-extension-providers</artifactId>

</dependency>

<groupId>org.codehaus.jettison</groupId>

<artifactId>jettison</artifactId>

</dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context</artifactId>

<version>4.1.7.RELEASE</version>

</dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-web</artifactId>

<version>4.1.7.RELEASE</version>

</dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-test</artifactId>

<version>4.1.7.RELEASE</version>

</dependency>

<groupId>junit</groupId>

<artifactId>junit</artifactId>

</dependency>

</dependencies>

<build>

<groupId>org.codehaus.mojo</groupId>

<artifactId>tomcat-maven-plugin</artifactId>

</configuration>

</plugin>

</plugins>

</build>

</project>

3.配置web.xml

完整的web.xml如下:

<?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/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

id="WebApp_ID" version="2.5">

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</context-param>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<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>

</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>

4.导入实体类和service
5.、在 spring 配置发布 rs 服务

引入名称空间

xmlns:jaxrs="http://cxf.apache.org/jaxrs" http://cxf.apache.org/jaxrshttp://cxf.apache.org/schemas/jaxrs.xsd

配置服务:

完整的applicationContext.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:jaxrs="http://cxf.apache.org/jaxrs"

xsi:schemaLocation="

http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd

http://cxf.apache.org/jaxrshttp://cxf.apache.org/schemas/jaxrs.xsd";>;

<jaxrs:server id="xxxService" address="/xxxService" >

<jaxrs:serviceBeans>

</jaxrs:serviceBeans>

<jaxrs:inInterceptors>

</jaxrs:inInterceptors>

<jaxrs:outInterceptors>

</jaxrs:outInterceptors>

</jaxrs:server>

</beans>

.配置服务启动端口(如果上面的pom.xml中没有配置,才需要配置这个,上面已经有了完整了pom.xml)

<build>

<groupId>org.codehaus.mojo</groupId>

<artifactId>tomcat-maven-plugin</artifactId>

</configuration>

</plugin>

</plugins>

</build>

6.编写客户端代码类似独立服务客户端代码 WebClient 工具实现

1) .在src/test/resource下面创建一个applicationContext-test.xml

内容如下:

<?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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd

http://cxf.apache.org/jaxrshttp://cxf.apache.org/schemas/jaxrs.xsd";>;

</beans>

2).创建client类

package cn.itcast.cxf.client;

import java.util.Collection;

import javax.ws.rs.core.MediaType;

import javax.ws.rs.core.Response;

import org.apache.cxf.jaxrs.client.WebClient;

import cn.itcast.cxf.domain.User;

/**

* @author: yangzhaoli

* @creationTime:2017年11月13日下午6:44:34

* @version: 1.1

public class Cxf_rs_springClient {

public static void main(String[] args) {

/*//查询根据id

WebClient client2 = WebClient.create("http://localhost:9800/cxf_rs_spring/services/userService/user/1");

User user2 = client2.accept(MediaType.APPLICATION_JSON).get(User.class);

System.out.println(user2);*/

//查询所有

/*WebClient webClient = WebClient.create("http://localhost:9800/cxf_rs_spring/services/userService/user").accept(MediaType.APPLICATION_XML);

Collection<? extends User> collection = webClient.getCollection(User.class);

System.out.println(collection);*/

//增加

/*User user = new User();

user.setId(9999);

user.setUsername("haha");

WebClient webClient = WebClient.create("http://localhost:9800/cxf_rs_spring/services/userService/user");

webClient.type(MediaType.APPLICATION_JSON).post(user);*/

//修改

WebClient client = WebClient.create("http://localhost:9800/cxf_rs_spring/services/userService/user");

User user = new User();

user.setId(2);

user.setUsername("hhh");

client.put(user);

}

注意:最终访问资源服务路径: 服务器根目录地址 + web.xml 配置(url ) + applicationContext.xml address 配置 + 类 @Path + 方法 @Path

例如:http://localhost:9800/cxf_rs_spring/services/userService/user
