JAX-WS + Spring integration example (轉自http://www.mkyong.com/webservices/jax-ws/jax-ws-spring-integration-example/）

Here’s a guide to show you how to integrate Spring with JAX-WS, as mention in this link : http://jax-ws-commons.java.net/spring/. Upon finishing this tutorial, you will create a simple HelloWorld web service (JAX-WS), and DI a bean into the web service via Spring.

1. Project Folder

See the final project folder structure.

2. Project Dependencies

Use Maven to get all the library dependencies. The key to integrate Spring with JAX-WS is via jaxws-spring.jar.

File : 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/4.0.0   http://maven.apache.org/maven-v4_0_0.xsd">   <modelVersion>4.0.0</modelVersion>   <groupId>com.mkyong</groupId>   <artifactId>WebServicesExample</artifactId>   <packaging>war</packaging>   <version>1.0-SNAPSHOT</version>   <name>WebServicesExample Maven Webapp</name>   <url>http://maven.apache.org</url>     <repositories>     <repository>       <id>java.net</id>       <url>http://download.java.net/maven/2</url>     </repository>   </repositories>     <dependencies>           <dependency>                 <groupId>junit</groupId>                 <artifactId>junit</artifactId>                 <version>3.8.1</version>                 <scope>test</scope>         </dependency>   	<!-- Spring framework -->  	<dependency> 		<groupId>org.springframework</groupId> 		<artifactId>spring</artifactId> 		<version>2.5.6</version> 	</dependency>           <!-- JAX-WS -->  	<dependency> 	  	<groupId>com.sun.xml.ws</groupId> 	        <artifactId>jaxws-rt</artifactId> 	        <version>2.2.3</version> 	</dependency>    	<!-- Library from java.net, integrate Spring with JAX-WS -->  	<dependency> 		<groupId>org.jvnet.jax-ws-commons.spring</groupId> 		<artifactId>jaxws-spring</artifactId> 		<version>1.8</version> 		<exclusions> 		  <exclusion>            		<groupId>org.springframework</groupId>       			<artifactId>spring-core</artifactId>         	  </exclusion>         	  <exclusion>            		<groupId>org.springframework</groupId>       			<artifactId>spring-context</artifactId>         	  </exclusion>         	  <exclusion>            		<groupId>com.sun.xml.stream.buffer</groupId>       			<artifactId>streambuffer</artifactId>         	  </exclusion>         	  <exclusion>            		<groupId>org.jvnet.staxex</groupId>       			<artifactId>stax-ex</artifactId>         	  </exclusion> 		</exclusions> 	</dependency>     </dependencies>   <build>     <finalName>web services</finalName>     <plugins>        <plugin>            <groupId>org.apache.maven.plugins</groupId>            <artifactId>maven-compiler-plugin</artifactId>            <version>2.3.1</version>            <configuration>                <source>1.6</source>                <target>1.6</target>            </configuration>        </plugin>     </plugins>   </build> </project>

Note
The jaxws-spring’s pom.xml has a lot of unnecessary dependencies, you may need to exclude it via </exclusions> tag.

3. JAX-WS Hello World

A simple JAX-WS example, and dependency inject (DI) “HelloWorldBo” via Spring.

File : HelloWorldWS.java

package com.mkyong.ws;   import javax.jws.WebMethod; import javax.jws.WebService;   import com.mkyong.bo.HelloWorldBo;   @WebService public class HelloWorldWS{   	//DI via Spring 	HelloWorldBo helloWorldBo;   	@WebMethod(exclude=true) 	public void setHelloWorldBo(HelloWorldBo helloWorldBo) { 		this.helloWorldBo = helloWorldBo; 	}   	@WebMethod(operationName="getHelloWorld") 	public String getHelloWorld() {   		return helloWorldBo.getHelloWorld();   	}   }

4. Beans

Here’s the HelloWorldBo class, with a getHelloWorld() method to return a simple string.

File : HelloWorldBo.java

package com.mkyong.bo;   public interface HelloWorldBo{   	String getHelloWorld();   }

File : HelloWorldBoImpl.java

package com.mkyong.bo.impl;   import com.mkyong.bo.HelloWorldBo;   public class HelloWorldBoImpl implements HelloWorldBo{   	public String getHelloWorld(){ 		return "JAX-WS + Spring!"; 	}   }

5. Spring Beans Configuration

Spring beans configuration file to bind URL pattern “/hello” to “com.mkyong.ws.HelloWorldWS” web service class.

File : 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:ws="http://jax-ws.dev.java.net/spring/core"        xmlns:wss="http://jax-ws.dev.java.net/spring/servlet"        xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  http://jax-ws.dev.java.net/spring/core  http://jax-ws.dev.java.net/spring/core.xsd  http://jax-ws.dev.java.net/spring/servlet  http://jax-ws.dev.java.net/spring/servlet.xsd" >       <wss:binding url="/hello">         <wss:service>             <ws:service bean="#helloWs"/>         </wss:service>     </wss:binding>       <!-- Web service methods -->     <bean id="helloWs" class="com.mkyong.ws.HelloWorldWS">     	<property name="helloWorldBo" ref="HelloWorldBo" />     </bean>       <bean id="HelloWorldBo" class="com.mkyong.bo.impl.HelloWorldBoImpl" />   </beans>

Note
With this jaxws-spring integration mechanism, the sun-jaxws.xml file is no longer required.

6. web.xml

In web.xml, declares “com.sun.xml.ws.transport.http.servlet.WSSpringServlet“, and link it to “/hello“.

<web-app id="WebApp_ID" version="2.4"  	xmlns="http://java.sun.com/xml/ns/j2ee"  	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">   	<display-name>Spring + JAX-WS</display-name>   	<servlet>     	        <servlet-name>jaxws-servlet</servlet-name>     	       <servlet-class>     		          com.sun.xml.ws.transport.http.servlet.WSSpringServlet     	        </servlet-class>   	</servlet>   	<servlet-mapping>                 <servlet-name>jaxws-servlet</servlet-name>                 <url-pattern>/hello</url-pattern>          </servlet-mapping>            <!-- Register Spring Listener -->   	<listener>     	        <listener-class>     		     org.springframework.web.context.ContextLoaderListener     	        </listener-class>   	</listener>   </web-app>

7. Demo

Start the project, and access the deployed web service via URL “/hello“, for example http://localhost:8080/WebServicesExample/hello?wsdl
