JAX-WS + Spring 开发webservice
通过几天的时间研究了下使用jax-ws来开发webservice,看了网上的一些资料总结出jax-ws的开发大概分为两种。
以下项目使用的spring3.0,jar包可以到官网下载
第一种:使用独立的端口(指端口可以在spring中自定义配置)
首先说第一种方式,这种方式不需要添加额外的jar包,他使用的是JDK自带的JWS来实现的。
web.xml文件配置:
<?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_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>JAXWSExample</display-name> <!-- applicationContext*.xml文件在src目录下的conf文件夹中--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/applicationContext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Log4j 日志 --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- 防止内存泄露 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener></web-app>
applicationContext-jaxws.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <context:annotation-config /> <context:component-scan base-package="com.example.ws"></context:component-scan> <!-- baseAddress 的value地址以及端口号是自定义的,端口号不要为已使用过的 --> <bean class="org.springframework.remoting.jaxws.SimpleJaxWsServiceExporter"> <property name="baseAddress" value="http://localhost:8088/" /> </bean> </beans>
java Code
package com.example.ws;import javax.jws.WebMethod;import javax.jws.WebService;import javax.jws.soap.SOAPBinding;import javax.jws.soap.SOAPBinding.Style;import org.springframework.stereotype.Service;// spring注解使用@Service("exampleService")// webservice地址使用@WebService(serviceName="example")// 防止jdk版本问题@SOAPBinding(style=Style.RPC)public class ExampleService { // dependency dao/service //@Autowired //private IBaseDao baseDao; @WebMethod public String example1 (String request){ System.out.println(request); String response= request + "hello"; return response; }}
java代码中方法写的比较简单,也可以将输入参数和输出参数写为对象,这个根据需求来定。
以上就是第一种方法的实现方式,本地访问地址直接是:http://localhost:8088/example?wsdl
第二种方式: 使用servlet方式,该方式使用服务器端口
此种方式的话需要依赖于jax-ws 2.2中的jar文件,另外还需要下载额外的jaxws-spring-1.8.jar和xbean-spring-3.0.jar
web.xml
<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 到END处用来配置启动spring容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/applicationContext*.xml</param-value> </context-param> <!-- END --> <!-- 用于配置地址栏请求路径 --> <servlet> <servlet-name>JaxWsServlet</servlet-name> <servlet-class>com.sun.xml.ws.transport.http.servlet.WSSpringServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>JaxWsServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping></web-app>
applicationContext-jaxws.xml,与之前不同之处在于,需要xml头需要增加wss的声明
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" 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://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-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">
<!-- 扫描spring注解 --> <context:annotation-config /> <context:component-scan base-package="com.example.ws"> </context:component-scan>
<!-- 绑定webservice地址,需要与web.xml的地址对应 --> <wss:binding url="/services/add"> <wss:service> <ws:service bean="#exampleService" /> </wss:service> </wss:binding>
</beans>
java Code
package com.example.ws;import javax.jws.WebMethod;import javax.jws.WebService;import javax.jws.soap.SOAPBinding;import javax.jws.soap.SOAPBinding.Style;import org.springframework.stereotype.Service;@Service("exampleService")
// 只有此处与方法一不同@WebService@SOAPBinding(style=Style.RPC)public class ExampleService { @WebMethod public String example1(String request){ System.out.println(request); String response = request+ "hello"; return response; }}
此种方式的本地请求地址为:http://localhost:8080/JAXWsExample2/services/add?wsdl
http://ip地址:服务器端口号/ 项目应用名/servlet定义地址?wsdl
以上两种方式本人在本地使用Tomcat服务都可以测试通过
在WebSphere服务器上目前测试只有第二种可用
