XFire webservice 服务端开发(一)

转载：http://www.cnblogs.com/boogle/archive/2008/09/20/1294924.html

网上介绍XFire方面的文章已经很多了，我主要是介绍一下与Spring开发的集成，做个例子，抛块砖吧。

 

个人感受：先谈个人感受，可以更加明确和了解开发中的思路，XFire与Spring可以说得上绝配，如果你开发所采用的架构是SSH模式，或者有Spring框架，那么你就正常开发，不要管web service，你只需要明白哪个类是用于web service的，并且在Spring测试通过，你的web service服务端开发可以说基本搞定。

 

说明：

我写这文章主要是说明开发过程及给个例子，并不是讲web service 协议或者spring开发。我有时间可以写点这方面的内容。

 

开发环境：

1，JDK 1.6.0

2，Eclipse JEE 3.4，外加XFire eclipse plugin（主要用于客户端开发）。

3，tomcat-5.5.26

4，SoapUI 主要用于测试。

5，下载xfire-distribution-1.2.6.zip，pjl-comp-filter-1.6.6.zip（用于传输压缩）

需求：

对外提供一个表的增删改查。

 

开发步骤：

1，建立web开发环境。

2，拷贝需要采用的依赖包。

3，开发业务功能。

4，配置Spring。

5，配置web service。

6，测试。

 

开发：

1，建立web开发环境。

用eclipse建立一个动态web项目（myeclipse也一样，需要配置tomcat用于提供web service）。

2，拷贝需要采用的依赖包。

解压xfire-distribution-1.2.6.zip，pjl-comp-filter-1.6.6.zip拷贝lib里面的内容及xfire-all-1.2.6.jar,pjl-comp-filter-1.6.6.jar,ORACLE驱动classes12.jar。

3，开发业务功能。

建立表结构

create table HD.HDUSER (   ID NUMBER(8) not null,   NAME NVARCHAR2(16) not null,   PASSWD NVARCHAR2(16) ) tablespace HANDLEWELL   pctfree 10   initrans 1   maxtrans 255   storage   (     initial 64K     minextents 1     maxextents unlimited   );

 

建立业务对象

 

public class User implements Serializable {     private static final long serialVersionUID = -4924323782825351658L;          private Integer id;     private String name;     private String passwd;     public Integer getId() {         return id;     }     public void setId(Integer id) {         this.id = id;     }     public String getName() {         return name;     }     public void setName(String name) {         this.name = name;     }     public String getPasswd() {         return passwd;     }     public void setPasswd(String passwd) {         this.passwd = passwd;     }     @Override     public String toString() {         StringBuffer sb = new StringBuffer("User:[");         sb.append("ID:").append(id).append(",");         sb.append("Name:").append(name).append(",");         sb.append("Passwd:").append(passwd).append("]");         return sb.toString();     } }

建立业务接口

 

public interface IUserService {     public boolean addUser(int id, String name, String passwd);     public boolean modifyUser(int id, String name, String passwd);     public User queryUser(int id);     public boolean deleteUser(int id); }

建立DAO接口

public interface IUserDAO {     public boolean addUser(User user);     public boolean modifyUser(User user);     public User queryUser(int id);     public boolean deleteUser(int id); }

实现DAO接口

public class UserDAOImpl extends JdbcDaoSupport implements IUserDAO {     @Override     public boolean addUser(User user) {         String sql = "insert into HDUSER(id, name, passwd)values(" + user.getId() + ",'" + user.getName() + "','" + user.getPasswd() + "')";         this.getJdbcTemplate().execute(sql);         return true;     }     @Override     public boolean deleteUser(int id) {         String sql = "delete from HDUSER where id=" + id;         this.getJdbcTemplate().execute(sql);         return true;     }     @Override     public boolean modifyUser(User user) {         // TODO Auto-generated method stub         return false;     }     @Override     public User queryUser(int id) {         // TODO Auto-generated method stub         return null;     } }

实现业务

public class UserServiceImpl implements IUserService {          private IUserDAO userDAO;          public IUserDAO getUserDAO() {         return userDAO;     }     public void setUserDAO(IUserDAO userDAO) {         this.userDAO = userDAO;     }     @Override     public boolean addUser(int id, String name, String passwd) {         User u = new User();         u.setId(new Integer(id));         u.setName(name);         u.setPasswd(passwd);         this.getUserDAO().addUser(u);         return true;     }     @Override     public boolean deleteUser(int id) {         // TODO Auto-generated method stub         return false;     }     @Override     public boolean modifyUser(int id, String name, String passwd) {         // TODO Auto-generated method stub         return false;     }     @Override     public User queryUser(int id) {         // TODO Auto-generated method stub         return null;     } }

4，配置Spring。

在WEB-INF下建立applicationContext.xml文件。

<?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="userBean" class="com.handlewell.user.service.impl.UserServiceImpl">         <property name="userDAO" ref="userDAO" />     </bean>          <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">            <property name="driverClass"><value>oracle.jdbc.driver.OracleDriver</value></property>            <property name="jdbcUrl"><value>jdbc:oracle:thin:@localhost:1521:orcl</value></property>         <property name="user"><value>hd</value></property>         <property name="password"><value>hd</value></property>     </bean>          <bean id="userDAO" class="com.handlewell.user.dao.impl.UserDAOImpl">         <property name="dataSource" ref="dataSource" />     </bean>  </beans>

在web.xml文件加入Spring配置

<!-- begin Spring 配置 -->     <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/applicationContext.xml,/WEB-INF/xfire-servlet.xml</param-value>     </context-param>      <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>      <listener>         <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>     </listener>     <!-- end Spring配置 -->

5，配置web service。

在WEB-INF下建立xfire-servlet.xml文件。

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"     "http://www.springframework.org/dtd/spring-beans.dtd"> <beans>     <!-- 引入XFire配置信息 -->     <import resource="classpath:org/codehaus/xfire/spring/xfire.xml" />          <!-- 定义访问的url-->     <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">        <property name="urlMap">             <map>                <entry key="/userService.ws">                    <ref bean="userService" />                </entry>             </map>         </property>      </bean>     <!-- 使用XFire导出器 -->     <bean id="baseWebService" class="org.codehaus.xfire.spring.remoting.XFireExporter" lazy-init="false" abstract="true">        <property name="serviceFactory" ref="xfire.serviceFactory" />        <property name="xfire" ref="xfire" />     </bean>          <!-- 建立web service服务 -->     <bean id="userService" parent="baseWebService">        <property name="serviceBean" ref="userBean" />        <property name="serviceClass" value="com.handlewell.user.service.IUserService" />     </bean> </beans>

在web.xml中加入

<!-- begin XFire 配置 -->     <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>     <!-- end XFire配置 -->

至此开发工作结束。

6，测试。

启动tomcat服务，先访问一下WSDL信息http://localhost:8080/sx/userService.ws?wsdl

生成的WSDL信息如下

</wsdl:definitions>

把内容存为文件。

启动soapUI,新建项目，并导入刚才的wsdl文件。

在addUser下request单击show request editor，就可以看到soap请求信息。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://service.user.handlewell.com">    <soapenv:Header/>    <soapenv:Body>       <ser:addUser>          <ser:in0>11</ser:in0>          <ser:in1>aaa</ser:in1>          <ser:in2>bbb</ser:in2>       </ser:addUser>    </soapenv:Body> </soapenv:Envelope>

提交，查看数据库，数据存入即成功。

有些朋友可能在webservice中各wsdl和soap协议各自的作用，我传人图片大家就明白了。
