概述
在web项目中发布基于jaxws的webservice。
参考文章说,如果不是servlet3.0及以上,需要配置servlet,请注意。
servlet3.0的web.xml的框架:
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 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" metadata-complete="false"> <display-name>Archetype Created Web Application</display-name> </web-app>
Maven依赖
<!-- JAXWS-RI --> <dependency> <groupId>com.sun.xml.ws</groupId> <artifactId>jaxws-rt</artifactId> <version>2.2.10</version> </dependency>

不使用Maven,需要人工导入上述jar包;可以尝试在http://mvnrepository.com/中获取。
服务实现
假设你已经清楚如何使用jaxws实现webservice,这里仅提供简略的说明和代码。
这里写一个简单的服务,返回“hello, jaxws!”字符串。
服务接口
IHelloJAXWSService.java
package cn.ljl.baseframe.test.jaxws; import javax.jws.WebResult; import javax.jws.WebService; @WebService public interface IHelloJAXWSService { @WebResult(name = "helloWorld") public String getHelloWord(); }
服务实现类
HelloJAXWSServiceImpl.java
package cn.ljl.baseframe.test.jaxws; import javax.jws.WebService; @WebService(endpointInterface = "cn.ljl.baseframe.test.jaxws.IHelloJAXWSService") public class HelloJAXWSServiceImpl implements IHelloJAXWSService { @Override public String getHelloWord() { String helloWorld = "hello, jaxws!"; return helloWorld; } }
配置endpoints
在WEB-INF目录下,添加sun-jaxws.xml文件,文件内容如下:
<?xml version="1.0" encoding="UTF-8"?> <endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime" version="2.0"> <!-- 服务路径http://网站路径/services/hello --> <endpoint name="hello" implementation="cn.ljl.baseframe.test.jaxws.HelloJAXWSServiceImpl" url-pattern="/services/hello" /> </endpoints>
注意:网上多个文章都要求这个文件是UTF-8编码,没有测试是否必须。
