webservice开发spring整合cxf入门案例
一、创建服务端发布服务
1. 添加依赖
<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 --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-rs-client</artifactId> <version>3.0.1</version> </dependency> <!-- 扩展json提供者 --> <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>4.2.4.RELEASE</version> </dependency> <!-- spring web集成 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.2.4.RELEASE</version> </dependency> <!-- spring 整合junit --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.2.4.RELEASE</version> </dependency> <!-- junit 开发包 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> </dependencies>
2. 创建服务接口
import javax.ws.rs.Consumes; import javax.ws.rs.DELETE; import javax.ws.rs.GET; import javax.ws.rs.POST; import javax.ws.rs.PUT; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import cn.itcast.domain.User; //@Path("/userService") @Produces("*/*") public interface IUserService { @POST @Path("/user") @Consumes({ "application/xml", "application/json" }) public void saveUser(User user); @PUT @Path("/user") @Consumes({ "application/xml", "application/json" }) public void updateUser(User user); @GET @Path("/user") @Produces({ "application/xml", "application/json" }) public List<User> findAllUsers(); @GET @Path("/user/{id}") @Consumes("application/xml") @Produces({ "application/xml", "application/json" }) public User finUserById(@PathParam("id") Integer id); @DELETE @Path("/user/{id}") @Consumes({"application/xml", "application/json"}) public void deleteUser(@PathParam("id") Integer id); }
3. 创建服务接口实现
import java.util.ArrayList; import java.util.List; public class UserServiceImpl implements IUserService { public void saveUser(User user) { System.out.println("save user:" + user); } public void updateUser(User user) { System.out.println("update user:" + user); } public List<User> findAllUsers() { List<User> users = new ArrayList<User>(); User user1 = new User(); user1.setId(1); user1.setUsername("小明"); user1.setCity("北京"); List<Car> carList1 = new ArrayList<Car>(); Car car1 = new Car(); car1.setId(101); car1.setCarName("保时捷"); car1.setPrice(1000000d); carList1.add(car1); Car car2 = new Car(); car2.setId(102); car2.setCarName("宝马"); car2.setPrice(400000d); carList1.add(car2); user1.setCars(carList1); users.add(user1); User user2 = new User(); user2.setId(2); user2.setUsername("小丽"); user2.setCity("上海"); users.add(user2); return users; } public User finUserById(Integer id) { if (id == 1) { User user1 = new User(); user1.setId(1); user1.setUsername("小明"); user1.setCity("北京"); return user1; } return null; } public void deleteUser(Integer id) { System.out.println("delete user id :" + id); } }
4. 配置web.xml
<!-- 1. 加载spring配置文件--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext-cxf.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 2.CXF的核心控制器 --> <servlet> <servlet-name>cxfServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>cxfServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping>
5. 配置applicationContext-cxf.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/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd"> <!-- 1. 通过容器发布服务 2. 服务访问地址 http://localhost:12345/web.xml配置/spring中的address地址/service接口地址 3. 如： http://localhost:12345/ws/userService --> <jaxrs:server address="/userService" serviceClass="cn.itcast.service.UserServiceImpl"/> </beans>
6. 启动项目发布服务
二、创建客户端调用服务
import org.apache.cxf.jaxrs.client.WebClient; import org.junit.Test; import javax.ws.rs.core.MediaType; import java.util.Collection; public class WebServiceClient { /** * webservice客户端调用服务 */ // 请求默认xml格式 @Test public void save() { User user = new User(); user.setId(10); user.setUsername("刘备"); //WebClient就是webservice客户端调用对象 WebClient.create("http://localhost:12345/userService/user") .post(user); } // 指定请求数据为json格式 @Test public void update() { User user = new User(); user.setUsername("关羽"); user.setId(12); user.setCity("荆州"); WebClient.create("http://localhost:12345/userService/user") .type(MediaType.APPLICATION_JSON) .put(user); } @Test public void findById() { User user = WebClient.create("http://localhost:12345/userService/user/1") .type(MediaType.APPLICATION_JSON) //指定请求数据格式 .accept(MediaType.APPLICATION_JSON)//响应数据格式 .get(User.class); System.out.println(user); } @Test public void findAll() { Collection<? extends User> users = WebClient.create("http://localhost:12345/userService/user") .getCollection(User.class); System.out.println(users); } @Test public void delete() { WebClient.create("http://localhost:12345/userService/user/1") .delete(); } }
