本文详细介绍了如何在Java中不整合Spring的情况下创建和发布Web Service，包括服务类的定义、发布以及客户端调用。此外，还讲解了整合Spring的Web Service实现，包括web.xml和Spring配置文件的设置，以及客户端调用的步骤。

一、纯java 编写，不整合spring

服务类（webservice)：

1. 建立java project ,导入jar包

2.创建服务类,添加注解@WebService

3.发布webservice

4.直接上代码：

1.整体架构

2.import javax.jws.WebService;

          @WebService
public interface IWeatherService {
            /**
             * 根据city 城市名返回天气
             * @param city
             * @return
                 */
            public String getWeather(String city);

}

                public class WeatherService implements IWeatherService{
            @Override
            public String getWeather(String city) {
             if("南京".equals(city)){
             return "大雨";
            }else{
         return "查询失败";
            }
                     }

}

                public class PublishTest {

发布webservice ,run as java
         public static void main(String[] args) {
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();

            factory.setAddress("http://localhost:12345/weather");

          factory.setServiceBean(new WeatherService());

                factory.create();
            }

}

访问网址 localhost:12345/weather?wsdl

客户端：

1 建立Java 工程，导入jar包

2 wsimport 生成webservice 的本地代码

在cmd 切换到src 目录下，

执行命令：wsimport -s . localhost:12345/weather?wsdl

（wsClient 项目src 的目录是 D:\workspaceMyec\wsClient\src）

3. 编写测试类

public class WeatherServiceInvoking {

@Test

public void Test() {

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

factory.setAddress("http://localhost:12345/weather?wsdl");

factory.setServiceClass(IWeatherService.class);

IWeatherService iws = (IWeatherService) factory.create();

String result = iws.getWeather("南京");

System.out.println(result);

}

结构图

二、整合spring 的webservice demo

1.建立web 项目导入jar

2.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/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>webwsService</display-name>
<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>

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


<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>


<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>

</web-app>

3.spring配置文件如下：

<?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:cxf="http://cxf.apache.org/core"
xmlns:jaxws="http://cxf.apache.org/jaxws"
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/core
http://cxf.apache.org/schemas/core.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd
http://cxf.apache.org/jaxrs
http://cxf.apache.org/schemas/jaxrs.xsd">


<bean id="weatherService" class="com.wizpower.WeatherService" >

</bean>

<jaxws:server address="/weather">
<jaxws:serviceBean>
<ref bean="weatherService" />
</jaxws:serviceBean>
</jaxws:server>

</beans>

3.发布到tomcat

4.访问地址：localhost:8080/项目名/ws/weather？wsdl (具体原因和上面对照address 和 /ws/*)

客户端：

1. 建立java project 就可以导入jar

2. wsimport -s . localhost:8080/项目名/ws/weather？wsdl 与纯java 类似

3.applicetionContext.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:cxf="http://cxf.apache.org/core"
xmlns:jaxws="http://cxf.apache.org/jaxws"
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/core
http://cxf.apache.org/schemas/core.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd
http://cxf.apache.org/jaxrs
http://cxf.apache.org/schemas/jaxrs.xsd">


<jaxws:client id="weatherBean" address="http://localhost:8080/webwsService/ws/weather?wsdl"
serviceClass="com.wizpower.IWeatherService">
</jaxws:client>

</beans>

4.测试；

public class SpringCxfTest {

@Test
public void fun(){
ApplicationContext application = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
IWeatherService iw = (IWeatherService) application.getBean("weatherBean");
String s = iw.getWeather("xuz ");
System.out.println(s);
}
}
