利用xfire编写webservice

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.XFire

ServletController;
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 = XFire

ServletController.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

version
=
"2.4"
 
xsi:schemaLocation
=
"http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
>
  <!-- 配置文件路径 开始 -->
    <

        <

        <

            /WEB-INF/classes/applicationContext*.xml
            classpath:org/codehaus/xfire

/spring

/xfire

.xml
        </
param-value
>
    </
context-param
>

    <!-- 启动时加载Spring

    <

        <

>
            org.spring

framework.web.context.ContextLoaderListener
        </

>
    </
listener
>
    <
listener
>
        <
listener-class
>
org.spring

</
listener-class
>
    </
listener
>

    <
listener
>
        <
listener-class
>
            org.spring

framework.web.util.IntrospectorCleanupListener
        </
listener-class
>
    </
listener
>

      <!-- XFire

      <
servlet

        <
servlet-name
>
xfire


</
servlet-name
>
        <
servlet-class
>
org.spring

framework.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)

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.spring

framework.org/dtd/spring

<

    <

id

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)

这个调用的页面在哪啊
