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
