jersey webservice 实例

1.       准备jersey webservice框架搭建需要的jar

2.       新建一个java web项目

3.       添加spring支持

4. 修改web.xml
<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <listener>

       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    </listener>

    <context-param>

       <param-name>contextConfigLocation</param-name>

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

    </context-param>

    <!-- Jersey 配置 -->

    <servlet>

       <servlet-name>JerseyServlet</servlet-name>

       <servlet-class>

           com.sun.jersey.spi.spring.container.servlet.SpringServlet

       </servlet-class>

       <init-param>

           <param-name>com.sun.jersey.config.property.packages</param-name>

           <!-- 系统启动时扫描的包的路径-->

           <param-value>com.jw.api.service</param-value>

          

       </init-param>

       <init-param>

           <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>

           <param-value>true</param-value>

       </init-param>

       <load-on-startup>1</load-on-startup>

    </servlet>

 

    <servlet-mapping>

       <servlet-name>JerseyServlet</servlet-name>

       <url-pattern>/api/*</url-pattern>

    </servlet-mapping>

 

    <welcome-file-list>

       <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

</web-app>

 

5. 新建一个applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>

<beans

    xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:p="http://www.springframework.org/schema/p"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

 

 

</beans>
