jersey spring jackson

1.  下载 jersey 和 spring 
http://jersey.java.net/

http://www.springsource.org/download/community?project=Spring%2520Framework

http://wiki.fasterxml.com/JacksonDownload

 

jersey-archive-1.12.zip

spring-framework-3.1.1.RELEASE.zip

jackson 1.9.5

2. eclipse新建web项目导入jar包

jersey-archive-1.12\lib\*.jar

 

spring-framework-3.1.1.RELEASE\dist

  org.springframework.aop-3.1.1.RELEASE.jar

org.springframework.asm-3.1.1.RELEASE.jar

org.springframework.beans-3.1.1.RELEASE.jar

org.springframework.context-3.1.1.RELEASE.jar

org.springframework.core-3.1.1.RELEASE.jar

org.springframework.expression-3.1.1.RELEASE.jar

org.springframework.web-3.1.1.RELEASE.jar

 

3. 配置web.xml文件

 

 <?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">

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

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

     <listener>
         <listener-class>
             org.springframework.web.context.request.RequestContextListener
         </listener-class>
     </listener>


     <!-- Jersey-->
     <servlet>
         <servlet-name>JerseyServlet</servlet-name>
         <servlet-class>
             com.sun.jersey.spi.spring.container.servlet.SpringServlet
         </servlet-class>
         <!-- 系统启动时扫描的包的路径-->
         <!--
             <init-param>
             <param-name>
             com.sun.jersey.config.property.packages
             </param-name>
             <param-value>test.jersey_spring.demo.resource</param-value>
             </init-param>
         -->
         <!-- 使用jackson处理json -->
         <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>/rest/*</url-pattern>
     </servlet-mapping>

 </web-app>

 

  4. 配置applicationContext.xml文件

applicationContext.xml

 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:context="http://www.springframework.org/schema/context"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
     http://www.springframework.org/schema/context
     http://www.springframework.org/schema/context/spring-context-3.0.xsd">

     <context:component-scan base-package="test.jersey_spring.demo" />

 </beans>

 5. 现在可以写类测试了，应当会报错，当使用jackson时

Error

 java.lang.VerifyError: (class: org/codehaus/jackson/map/ObjectMapper, method: writeValueAsBytes signature: (Ljava/lang/Object;)[B) Incompatible argument to function

 jersey-1.12 里使用的jackson是1.9.1版本的，替换为1.9.5-asl 的版本就可以了
