利用xfire编写webservice的例子,内容如下
1. xfire + spring 发布webservice
2. 利用 javascript? 调用发布的webservice
使用xfire+spring发布webservice其实很简单,遵循一下几个步骤即可
1. 想要发布成文webservice的类,必须实现接口
2. 3个配置文件(后面详细说)
下面针对以上步骤详细说明
关于1中的要求,给个例子就明白了
Itest.java 代码
?
- package?test;??
- ??
- import?org.json.JSONException;??
- ??
- public?interface?IHello??
- {??
- ????public?String?hello();??
- ????public?String?helloTo(String?name);??
- ????public?String?getJsonData(String?pageIndex,String?pageSize);??
- }??
????
HelloImpl.java 代码
?
- package?test;??
- ??
- import?java.util.*;??
- ??
- import?javax.servlet.http.HttpServletRequest;??
- import?javax.servlet.http.HttpSession;??
- ??
- import?org.codehaus.xfire.transport.http.XFireServletController;??
- import?org.json.JSONException;??
- import?org.json.JSONStringer;??
- ??
- public?class?HelloImpl?implements?IHello??
- {??
- ??
- ????public?String?hello()??
- ????{??
- ????return?"hello";??
- ????}??
- ??
- ????public?String?helloTo(String?name)??
- ????{??
- ????return?"?hello?"?+?name?+?"!";??
- ????}??
- ??
- ????private?void?example()??
- ????{??
- ??????
- ?????HttpServletRequest?request?=?XFireServletController.getRequest();??
- ?????HttpSession?session?=?request.getSession();??
- ????}??
- ??
- ????public?String?getJsonData(String?pageIndex,String?pageSize)???
- ????{??
- ????String?rtnValue?=?"";??
- ??????
- ????rtnValue?=?"";??
- ????for(int?i=0;i<Integer.parseInt(pageSize);i++)??
- ????{??
- ????????rtnValue?=?rtnValue?+?"{'lastname':?'last"?+?pageIndex?+?"-"?+?i?+?"',?'firstname':?'first"?+?pageIndex?+?"-"?+?i?+?"'?},";??
- ????}??
- ????rtnValue?=?rtnValue?+?"{'lastname':?'last',?'firstname':?'last'?}";??
- ??????
- ????rtnValue?=?"{'context':["??+?rtnValue?+?"],'pager':[{'totalRecord':'100','totalpage':'10','pageIndex':'"?+?pageIndex?+?"','pageSize':'10'}]}";??
- ??????
- ????return?rtnValue;??
- ????}??
- }??
就这样写就可以了
关于三个配置文件
web.xml修改如下
xml 代码
?
- <?xml?version="1.0"?encoding="UTF-8"?>??
- <web-app?xmlns="http://java.sun.com/xml/ns/j2ee"?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"?version="2.4"?xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee???http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">??
- ????
- ????<context-param>??
- ????????<param-name>log4jConfigLocation</param-name>??
- ????????<param-value>/WEB-INF/classes/log4j.properties</param-value>??
- ????</context-param>??
- ????<context-param>??
- ????????<param-name>contextConfigLocation</param-name>??
- ????????<param-value>??
- ????????????/WEB-INF/classes/applicationContext*.xml??
- ????????????classpath:org/codehaus/xfire/spring/xfire.xml??
- ????????</param-value>??
- ????</context-param>??
- ??????
- ??????
- ????<listener>??
- ????????<listener-class>??
- ????????????org.springframework.web.context.ContextLoaderListener??
- ????????</listener-class>??
- ????</listener>??
- ????<listener>???
- ????????<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>???
- ????</listener>???
- ??
- ????<listener>??
- ????????<listener-class>??
- ????????????org.springframework.web.util.IntrospectorCleanupListener??
- ????????</listener-class>??
- ????</listener>??
- ??????
- ????????
- ??????<servlet>???
- ????????<servlet-name>xfire</servlet-name>???
- ????????<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>???
- ??????</servlet>???
- ????????
- ??????<servlet-mapping>??
- ????????<servlet-name>xfire</servlet-name>??
- ????????<url-pattern>*.ws</url-pattern>??
- ??????</servlet-mapping>??
- ????????
- ??????<welcome-file-list>??
- ????????<welcome-file>index.html</welcome-file>??
- ??????</welcome-file-list>??
- </web-app>??
这里注意 ? classpath:org/codehaus/xfire/spring/xfire.xml? 必须要写进去
xfire-servlet.xml 新建这个文件,并且和web.xml放在同一个文件夹
注意: 名称和位置都不能变(也许可以改,我不知道)
xml 代码
- <?xml?version="1.0"?encoding="UTF-8"?>??
- <!DOCTYPE?beans?PUBLIC?"-//SPRING//DTD?BEAN//EN"?"http://www.springframework.org/dtd/spring-beans.dtd">??
- <beans>???
- ????<bean?class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">???
- ????????<property?name="urlMap">??
- ????????????<map>??
- ????????????????<entry?key="/testService.ws">??
- ????????????????????<ref?bean="test"/>????
- ????????????????</entry>???
- ????????????</map>???
- ????????</property>??
- ??????</bean>???
- ????????
- ??????<bean?id="test"?parent="webService"?class="org.codehaus.xfire.spring.remoting.XFireExporter">???

- ????????</property>??
- ????????<property?name="xfire">??

- ????????</property>??
- ?????</bean>??
- </beans>??
spring 的配置文件 applicationContext-webService.xml
xml 代码
- <?xml?version="1.0"?encoding="UTF-8"?>??
- <!DOCTYPE?beans?PUBLIC?"-//SPRING//DTD?BEAN//EN"?"http://www.springframework.org/dtd/spring-beans.dtd">????
- <beans>??
- ????<bean?id="testBean"?class="test.HelloImpl"></bean>??
- </beans>??
查看wsdl??? http://localhost:8080/mootools/testService.ws?wsdl
运行 进入 index.html 页面,点击 即可执行调用,正常显示表示发布成功,调用失败会返回error(运行前请修改index.html文件的源码,将url修改成真正的url)
例子很简单,不过多解释,源码查看附件
