使用xfire+spring編寫webservice例子

 

利用xfire編寫webservice的例子,內容如下

1. xfire + spring 發佈webservice
2. 利用 javascript  調用發佈的webservice

使用xfire+spring發佈webservice其實很簡單,遵循一下幾個步驟即可

1. 想要發佈成文webservice的類,必須實現接口
2. 3個配置文件(後面詳細說)

下面針對以上步驟詳細說明
關於1中的要求,給個例子就明白了

Itest.java 代碼

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 代碼

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()
    {
    //使用session
     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;
    }
}

就這樣寫就可以了

關於三個配置文件

web.xml修改如下

xml 代碼

<?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">
  <!-- 配置文件路徑 開始 -->
    <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>

    <!-- 啓動時加載SpringContextServlet -->
    <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>

      <!-- 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>

      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
      </welcome-file-list>
</web-app>

這裏注意   classpath:org/codehaus/xfire/spring/xfire.xml  必須要寫進去

xfire-servlet.xml 新建這個文件,並且和web.xml放在同一個文件夾
注意: 名稱和位置都不能變(也許可以改,我不知道)

xml 代碼

<?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 name="serviceBean">
            <ref bean="testBean"/>
        </property>
        <property name="serviceClass">
            <value>test.IHello</value>
        </property>
      </bean>

      <!-- webService base -->
      <bean id="webService" class="org.codehaus.xfire.spring.remoting.XFireExporter" abstract="true">
        <property name="serviceFactory">
            <ref bean="xfire.serviceFactory" />
        </property>
        <property name="xfire">
            <ref bean="xfire" />
        </property>
     </bean>
</beans>

spring 的配置文件 applicationContext-webService.xml

xml 代碼

<?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

運行 進入 index.html 頁面,點擊 即可執行調用,正常顯示錶示發佈成功,調用失敗會返回error(運行前請修改index.html文件的源碼,將url修改成真正的url)

例子很簡單,不過多解釋,源碼查看附件
