• CXF-JAX-WS开发(一)入门案例


    一、Web Service

    1、定义

     W3C定义,Web服务(Web service)应当是一个软件系统,用以支持网络间不同机器的互动操作。

    2、作用

    多系统间数据通信

    二、CXF是什么?

      CXF是目前最主流Web Service 开源的开发框架 ,由Apache提供。支持JAX-WS 和 JAX-RS。

    三、CXF-JAX-WS入门案例

      1、简介

        方法驱动。基于SOAP协议[SOAP=HTTP+XML ]XML格式传输数据。

      2、quickstart

        2.1、创建maven project[Packaging:jar]

          

    1 <groupId>org.cxf.maven</groupId>
    2 <artifactId>cxf_ws_helloworld</artifactId>
    3 <version>1.0.0-SNAPSHOT</version>
    4 <name>cxf_ws_helloworld</name>
    5 <description>CXF开发(一)JAX-WS快速入门</description>

       2.2、添加依赖

     1 <dependencies>
     2         <!-- JAX-WS -->
     3         <dependency>
     4             <groupId>org.apache.cxf</groupId>
     5             <artifactId>cxf-rt-frontend-jaxws</artifactId>
     6             <version>3.0.1</version>
     7         </dependency>
     8         <dependency>
     9             <groupId>org.apache.cxf</groupId>
    10             <artifactId>cxf-rt-transports-http-jetty</artifactId>
    11             <version>3.0.1</version>
    12         </dependency>
    13         <!-- 日志 -->
    14         <dependency>
    15             <groupId>org.slf4j</groupId>
    16             <artifactId>slf4j-log4j12</artifactId>
    17             <version>1.7.12</version>
    18         </dependency>
    19 </dependencies>

        2.3、引入 log4j.properties  ,放置到resoiurces

        

     1 ### direct log messages to stdout ###
     2 log4j.appender.stdout=org.apache.log4j.ConsoleAppender
     3 log4j.appender.stdout.Target=System.out
     4 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
     5 log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
     6 
     7 ### direct messages to file mylog.log ###
     8 log4j.appender.file=org.apache.log4j.FileAppender
     9 log4j.appender.file.File=c:/mylog.log
    10 log4j.appender.file.layout=org.apache.log4j.PatternLayout
    11 log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
    12 
    13 ### set log levels - for more verbose logging change 'info' to 'debug' ###
    14 
    15 log4j.rootLogger=info, stdout

        2.4、搭建服务端

            

          2.4.1、导入实体bean

            

            ①Car.java

     1 package org.cxf_ws.domain;
     2 
     3 public class Car {
     4     private Integer id;
     5     private String carName;
     6     private Double price;
     7 
     8     public Integer getId() {
     9         return id;
    10     }
    11 
    12     public void setId(Integer id) {
    13         this.id = id;
    14     }
    15 
    16     public String getCarName() {
    17         return carName;
    18     }
    19 
    20     public void setCarName(String carName) {
    21         this.carName = carName;
    22     }
    23 
    24     public Double getPrice() {
    25         return price;
    26     }
    27 
    28     public void setPrice(Double price) {
    29         this.price = price;
    30     }
    31 
    32     @Override
    33     public String toString() {
    34         return "Car [id=" + id + ", carName=" + carName + ", price=" + price + "]";
    35     }
    36 
    37 }

             ②User.java

     1 package org.cxf_ws.domain;
     2 
     3 import java.util.ArrayList;
     4 import java.util.List;
     5 
     6 public class User {
     7     private Integer id;
     8     private String username;
     9     private String city;
    10 
    11     private List<Car> cars = new ArrayList<Car>();
    12 
    13     public Integer getId() {
    14         return id;
    15     }
    16 
    17     public void setId(Integer id) {
    18         this.id = id;
    19     }
    20 
    21     public String getUsername() {
    22         return username;
    23     }
    24 
    25     public void setUsername(String username) {
    26         this.username = username;
    27     }
    28 
    29     public String getCity() {
    30         return city;
    31     }
    32 
    33     public void setCity(String city) {
    34         this.city = city;
    35     }
    36 
    37     public List<Car> getCars() {
    38         return cars;
    39     }
    40 
    41     public void setCars(List<Car> cars) {
    42         this.cars = cars;
    43     }
    44 
    45 }

          2.4.2、构建服务bean

            ①IUserService.java

     1 package org.cxf_ws.service;
     2 
     3 import java.util.List;
     4 
     5 import javax.jws.WebMethod;
     6 import javax.jws.WebService;
     7 
     8 import org.cxf_ws.domain.Car;
     9 import org.cxf_ws.domain.User;
    10 
    11 @WebService
    12 // @WebService,该注解使用在类上面,标记类是WebService服务提供对象(必须填写)
    13 public interface IUserService {
    14     @WebMethod
    15     // 传递字符串的名称,返回字符串的值
    16     public String sayHello(String name);
    17 
    18     // @WebMethod,该注解使用在方法上面,标记方法是WebService服务提供的方法(可省略)
    19     // 传递User对象,返回当前用户拥有的车
    20     public List<Car> findCarsByUser(User user);
    21 }

            ②UserServiceImpl.java

     1 package org.cxf_ws.service;
     2 
     3 import java.util.ArrayList;
     4 import java.util.List;
     5 
     6 import javax.jws.WebService;
     7 
     8 import org.cxf_ws.domain.Car;
     9 import org.cxf_ws.domain.User;
    10 
    11 @WebService(endpointInterface/* 接口服务完整类名 */= "org.cxf_ws.service.IUserService", serviceName/* 服务名称 */= "userService")
    12 public class UserServiceImpl implements IUserService {
    13 
    14     public String sayHello(String name) {
    15         // 执行查询数据库的逻辑
    16         return "Hello," + name;
    17     }
    18 
    19     public List<Car> findCarsByUser(User user) {
    20         // 执行查询数据库的逻辑
    21         // 这里本应该查询数据库的,为了演示,做一些假数据
    22         if ("xiaoming".equals(user.getUsername())) {
    23             List<Car> cars = new ArrayList<Car>();
    24             Car car1 = new Car();
    25             car1.setId(1);
    26             car1.setCarName("大众");
    27             car1.setPrice(200000d);
    28             cars.add(car1);
    29             Car car2 = new Car();
    30             car2.setId(2);
    31             car2.setCarName("现代");
    32             car2.setPrice(170000d);
    33             cars.add(car2);
    34             return cars;
    35         } else {
    36             return null;
    37         }
    38     }
    39 }

          2.4.3、配置jre环境1.5以上[使注解@WebService和@WebMethod生效]

            ①方案一、在pom.xml中配置plugin(本文采用)

     1 <build>
     2     <plugins>
     3         <plugin>
     4             <groupId>org.apache.maven.plugins</groupId>
     5             <artifactId>maven-compiler-plugin</artifactId>
     6             <version>2.3.2</version>
     7             <configuration>
     8                 <source>1.7</source>
     9                 <target>1.7</target>
    10             </configuration>
    11         </plugin>
    12     </plugins>
    13 </build>

            ②方案二、eclipse配置

              (1)全局配置

                

              (2)项目配置

                

        2.5、发布服务

          2.5.1、方案一、Jdk  

     1 package org.cxf_ws.server;
     2 
     3 import javax.xml.ws.Endpoint;
     4 
     5 import org.cxf_ws.service.IUserService;
     6 import org.cxf_ws.service.UserServiceImpl;
     7 
     8 public class JAX_WS_Server_Jdk {
     9 
    10     /**
    11      * JDK发布webservice
    12      *   * 生成客户端的代码wsimport
    13      */
    14     public static void main(String[] args) {
    15         // 1、创建服务实现类对象
    16         IUserService userService = new UserServiceImpl();
    17         // 2、定义服务地址
    18         String address = "http://localhost:9999/userService";
    19         // 3、发布服务
    20         Endpoint.publish(address, userService);
    21         // 4、打印信息
    22         System.out.println("helloService 服务已经启动 ...");
    23     }
    24 }

          2.5.2、案二、CXF_JaxWsServerFactoryBean

     1 package org.cxf_ws.server;
     2 
     3 import org.apache.cxf.interceptor.LoggingInInterceptor;
     4 import org.apache.cxf.interceptor.LoggingOutInterceptor;
     5 import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
     6 import org.cxf_ws.service.IUserService;
     7 import org.cxf_ws.service.UserServiceImpl;
     8 
     9 public class JAX_WS_Server_JaxWsServerFactoryBean {
    10 
    11     /**
    12      * CXF发布
    13      */
    14     public static void main(String[] args) {
    15         //    1、创建服务实现类 对象
    16         IUserService userService = new UserServiceImpl();
    17         //    2、定义服务地址
    18         String address = "http://localhost:9999/userService";
    19         //    3、创建JaxWsServer对象
    20         JaxWsServerFactoryBean jaxWsServer = new JaxWsServerFactoryBean();
    21         jaxWsServer.setServiceBean(userService);
    22         jaxWsServer.setAddress(address);
    23         //    4、打印日志,可以让我们看到传输的数据,SOAP协议=HTTP协议+XML数据
    24         jaxWsServer.getInInterceptors().add(new LoggingInInterceptor());
    25         jaxWsServer.getOutInterceptors().add(new LoggingOutInterceptor());
    26         //    5、发布服务
    27         jaxWsServer.create();
    28         //    6、打印信息
    29         System.out.println("CXF服务发布成功!");
    30     }
    31 }

          2.5.3、测试发布服务是否成功(webservice的使用说明书

            输入地址localhost:9999/userService?wsdl

            

        2.6、搭建客户端

            

          2.6.1、JDKwsimport命令生成本地调用WebService服务的代码

            使用wsimport命令解析WSDL文档:wsimport -s . http://localhost:9999/userService?wsdl[webservice说明书地址]

    名称 含义

    wsimport

    JDK命令

    -s

    生成代码

    .

    当前路径,I.e. D: estcxf

    http://localhost:9999/userService?wsdl

    webservice说明书地址

            

          2.6.2、创建客户端maven project[Packaing:jar]

            

    1 <groupId>org.cxf.maven</groupId>
    2 <artifactId>cxf_ws_helloworld_client</artifactId>
    3 <version>1.0.0-SNAPSHOT</version>
    4 <name>cxf_ws_helloworld_client</name>
    5 <description>CXF开发(一)JAX-WS快速入门之客户端</description>

          2.6.3、复制调用WebService服务的代码到客户端工程

            

        2.7、测试客户端工程访问服务端工程

          2.7.1、JDK-TestWebService.java

     1 package org.cxf_ws.service;
     2 
     3 import java.util.List;
     4 
     5 /**
     6  * 基于JDK提供的wsimport命令解析WSDL文档生成本地代码 
     7  * 使用本地代码生成一个代理对象,通过代理对象可以发送HTTP请求
     8  * 请求webservice服务
     9  */
    10 public class TestWebService {
    11     public static void main(String[] args) {
    12         UserService userService = new UserService();
    13         IUserService proxy = userService.getUserServiceImplPort();
    14         System.out.println(proxy.sayHello("张无忌"));
    15         User user = new User();
    16         user.setUsername("xiaoming");
    17         List<Car> list = proxy.findCarsByUser(user);
    18         for (Car car : list) {
    19             System.out.println(car.getId() + ":" + car.getCarName() + ":" + car.getPrice());
    20         }
    21     }
    22 }

            

          2.7.2、CXF
