webservice整合spring cxf

下载cxf包，把他里面的包都添加进lib文件夹中。

创建一个接口。添加@WebService注解

@WebService
public interface HelloWorld {

    String sayHi(@WebParam(name="text")String text);
    String sayHiToUser(User user);
    String[] SayHiToUserList(List<User> userList);
}

创建接口的实现类，也添加@WebService注解，给他一个名称:boy

@WebService(serviceName="boy")
public class HelloWorldImpl implements HelloWorld {

    Map<Integer, User> users = new LinkedHashMap<Integer, User>();

    public String sayHi(String text) {
        return "Hello " + text;
    }

    public String sayHiToUser(User user) {
        users.put(users.size() + 1, user);
        return "Hello " + user.getName();
    }

    public String[] SayHiToUserList(List<User> userList) {
        String[] result = new String[userList.size()];
        int i = 0;
        for (User u : userList) {
            result[i] = "Hello " + u.getName();
            i++;
        }
        return result;
    }

}

User实体类：

public class User {

    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    
}

服务端代码：

public class webServiceApp {
      public static void main(String[] args) {
          System.out.println("web service start");
          HelloWorldImpl implementor= new HelloWorldImpl();
          String address="http://localhost:8000/helloWorld";
          Endpoint.publish(address, implementor);
          System.out.println("web service started");
 }
}

客户端代码：有集成spring和没集成的

public class HelloWorldClient {
    public static void main(String[] args) {
        
        //集成spring和cxf
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        HelloWorld client1 = (HelloWorld) context.getBean("client1");
        User user1 = new User();
        user1.setName("Tony");
        user1.setAge(20);
        User user2 = new User();
        user2.setName("freeman");
        user2.setAge(50);
        List<User> userList = new ArrayList<User>();
        userList.add(user1);
        userList.add(user2);
        // String[] res = client1.SayHiToUserList(userList);
        // System.out.println(res[0]);
        // System.out.println(res[1]);
        String sayHi = client1.sayHi("good");
        System.out.println(sayHi);
        
        // HelloWorld2 client2 = (HelloWorld2) context.getBean("client2");
        // User user3 = new User();
        // user3.setName("Jerry");
        // user3.setAge(20);
        // String user = client2.sayHiToUser(user3);
        // System.out.println(user);
        
        
        //没有集成
        JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean();
        svr.setServiceClass(HelloWorld.class);
        svr.setAddress("http://localhost:8000/helloWorld");
        HelloWorld hw = (HelloWorld) svr.create();
        User user = new User();
        user.setName("Tony");
        System.out.println(hw.sayHi("ffff"));

    
    }
}

打印的结果是:

Hello good

Hello ffff

web.xml的配置

applicationContext.xml的配置，这个文件是放在资源文件resources下的，他在项目中的路径是在classes里面的。我在这里配置了两个站点。都是可以的。

<?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"
    
    xsi:schemaLocation="

        <property name="address" value="http://localhost:8000/helloWorld/aaa" />
    </bean>
    
    <!-- 第二个站点 -->
<!--     <jaxws:endpoint id="orange" implementor="com.cs.webservice.HelloWorldImpl2"
        address="/bbb" />

    <bean id="clientFactory2" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">

        <property name="address" value="http://localhost:8080/cxfwebservicespring/bbb" />
    </bean> -->
</beans>

<property name="address" value="http://localhost:8000/helloWorld/aaa" />
aaa前面的路径必须与发布的String address="http://localhost:8000/helloWorld";路径相同。
