WebService开发实例 (Xfire+Spring+Hibernate)

请注意，需要下载Xfire1.2.6
、spring2.0,hibernate 3.0
相关类库及相关数据库的jdbc
驱动。本文相关内容是在myeclipse5.1
下完成。



一、



首先在web.xml
中添加对xfire
及spring
支持的相关内容，如下:

<!-- jdbc_connect.properties
文件内容,
主要是数据库配置,
以下是oracle
数据库 -->



jdbc.driverClassName=

oracle.jdbc.driver.OracleDriver

jdbc.url=

jdbc
:

oracle:thin:@172.17.99.230:1521:bsrun

jdbc.username=

user

jdbc.password=

user

hibernate.dialect=

org.hibernate.dialect.Oracle9Dialect



三、



xfire-servlet.xml

文件内容,
如下:



<?
xml
version
=

"1.0"
encoding
=

"UTF-8"
?>

<!
DOCTYPE
beans
PUBLIC
"-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd"

>



<
beans
>



<!-- START SNIPPET: xfire -->



<
bean
class
=

"org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"
>



<
property
name
=

"urlMap"
>



<
map
>



<
entry
key
=

"/QueryService"
>



<
ref
bean
=

"query"
/>



</
entry
>





</
map
>



</
property
>





</
bean
>





<!-- Declare a parent bean with all properties common to both services -->



<
bean
id
=

"query"
class
=

"org.codehaus.xfire.spring.remoting.XFireExporter"
>



<
property
name
=

"serviceFactory"
>



<
ref
bean
=

"xfire.serviceFactory"
/>



</
property
>



<
property
name
=

"xfire"
>



<
ref
bean
=

"xfire"
/>



</
property
>



<
property
name
=

"serviceBean"
>



<
ref
bean
=

"QueryHibRis"
/>

<!

—
请注意这个需在applicationContext.xml
有定义-->





</
property
>



<
property
name
=

"serviceClass"
>



<
value
>
Hello
.

IHelloworld
</
value
>



</
property
>






</
bean
>




<!-- END SNIPPET: xfire -->

</
beans
>



四、Hello.HelloworldImpl
类内容，主要是查询数据库并返回结果





package Hello;



　

import java.util.Collection;



//Generated by MyEclipse



public class HelloworldImpl implements IHelloworld {




public Collection User(){



return getHibernateTemplate().find("

select new Helloworld.User(userid,username
) from emp");

　






}



}



IHelloworld
接口内容

package Hello;

//Generated by MyEclipse



import java.util.Collection;

　



public interface IHelloworld {




public Collection User();

}

//xfire
对于返回collection
的，需要定义接口的IHelloworld.aegis.xml
文件,
需放在当前接口文件目录下。



<?xml version="1.0" encoding="UTF-8"?>


<mappings>


<mapping>


<method name= "User" >


<return-type componentType= "Helloworld.User" />


</method>




</mapping>



</mappings>



Helloworld.User
类内容:



package Helloworld;



public class User {




String userid;


String username;

//
一定要定义此构造函数,在Hello.HelloworldImpl中有用到哟


。


Public User(String userid,String username){


this.userid = userid;

this.username = username;



}




public String getUserid() {


return userid;


}


public void setUserid(String userid) {


this.userid = userid;


}


public String getUsername() {


return username;


}


public void setUsername(String username) {


this.username = username;


}



}


完结，以上代码是我在实际应用中改编而成，都经过测试，肯定好用。
