利用resteasy框架构建rest webservice----第四波：resteasy与spring真正集成发布我们的restful webservice 服务（实例、教程）

原本以为根据文档集成resteasy与spring很简单，但是却还是花费的一定时间，避免大家走弯路----现在网上有的相关的集成都只是，spring加入进项目，木有与resteasy真正集成

老规矩，先上MAVEN的配置文件中依赖包：

<dependencies>
<!--corelibrary-->
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxrs</artifactId>
<version>2.2.1.GA</version>
</dependency>

<!--optionalmodules-->
<!--Springintegration-->
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-spring</artifactId>
<version>2.2.1.GA</version>
</dependency>

<!--JAXBsupport-->
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxb-provider</artifactId>
<version>2.2.1.GA</version>
</dependency>

<!--spring-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>2.5.6.SEC03</version>
</dependency>
</dependencies>

注意上图中得resteasy-spring模块依赖，和spring依赖

resteasy-spring直接配置似乎不能自动下载，如果不行可以自己去官网下载然后安装到私服仓库

还有spring的依赖必须是要有的，resteasy-spring只是提供集成代码

2.关键的web.xml中得配置

<!DOCTYPEweb-appPUBLIC
"-//SunMicrosystems,Inc.//DTDWebApplication2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
<display-name>ArchetypeCreatedWebApplication</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext*.xml</param-value>
</context-param>
<!--

<context-param>

<param-name>resteasy.scan.resources</param-name>
<param-value>true</param-value>
</context-param>
-->
<listener>
<listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
</listener>

<listener>
<listener-class>org.jboss.resteasy.plugins.spring.SpringContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>Resteasy</servlet-name>
<servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>Resteasy</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

</web-app>

相比原来的配置文件多了

<listener-class>org.jboss.resteasy.plugins.spring.SpringContextLoaderListener</listener-class>

和

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

3.application.xml的配置

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<!--servicepoint-->
<beanid="testServicePoint"class="com.jd.interfacce.service.point.TestServicePoint">
<propertyname="manager"ref="manager"/>
</bean>
<!--MANAGER-->
<beanid="manager"class="com.jd.interfacce.manager.impl.ManagerImpl"/>
</beans>

其中

testServicePoint

是我们的资源resouce也就是发布接口的类

4.资源类

packagecom.jd.interfacce.service.point;

importjavax.ws.rs.GET;
importjavax.ws.rs.Path;
importjavax.ws.rs.PathParam;

importcom.jd.interfacce.manager.Manager;
/**
*servicepointendpoint
*@author
*
*/
@Path(value="/")
publicclassTestServicePoint{
Managermanager;

@GET
@Path(value="/echo/{message}")
publicStringgetMessage(@PathParam(value="message")Stringmessage)
{
//returnmessage;
returnmanager.getMessage(message);
}

publicManagergetManager(){
returnmanager;
}
publicvoidsetManager(Managermanager){
this.manager=manager;
}
}

5.manager类

packagecom.jd.interfacce.manager.impl;

importcom.jd.interfacce.manager.Manager;

publicclassManagerImplimplementsManager{
@Override
publicStringgetMessage(Stringmessage)
{
returnmessage;
}
}
