org.springframework.expression-3.1.1.RELEASE.jar

org.springframework.web-3.1.1.RELEASE.jar

 

3. 配置web.xml文件

 

Web.xml代码  

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"  
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
4.     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
5.     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  
6.   
7.     <context-param>  
8.         <param-name>contextConfigLocation</param-name>  
9.         <param-value>classpath:applicationContext.xml</param-value>  
10.     </context-param>  
11.   
12.     <listener>  
13.         <listener-class>  
14.             org.springframework.web.context.ContextLoaderListener  
15.         </listener-class>  
16.     </listener>  
17.   
18.     <listener>  
19.         <listener-class>  
20.             org.springframework.web.context.request.RequestContextListener  
21.         </listener-class>  
22.     </listener>  
23.   
24.   
25.     <!-- Jersey-->  
26.     <servlet>  
27.         <servlet-name>JerseyServlet</servlet-name>  
28.         <servlet-class>  
29.             com.sun.jersey.spi.spring.container.servlet.SpringServlet  
30.         </servlet-class>  
31.         <!-- 系统启动时扫描的包的路径-->  
32.         <!--   
33.             <init-param>  
34.             <param-name>  
35.             com.sun.jersey.config.property.packages  
36.             </param-name>  
37.             <param-value>test.jersey_spring.demo.resource</param-value>  
38.             </init-param>  
39.         -->  
40.         <!-- 使用jackson处理json -->  
41.         <init-param>  
42.             <param-name>  
43.                 com.sun.jersey.api.json.POJOMappingFeature  
44.             </param-name>  
45.             <param-value>true</param-value>  
46.         </init-param>  
47.         <load-on-startup>1</load-on-startup>  
48.     </servlet>  
49.   
50.     <servlet-mapping>  
51.         <servlet-name>JerseyServlet</servlet-name>  
52.         <url-pattern>/rest/*</url-pattern>  
53.     </servlet-mapping>  
54.   
55. </web-app>  

 

  4. 配置applicationContext.xml文件

applicationContext.xml

Xml代码  

1. <beans xmlns="http://www.springframework.org/schema/beans"  
2.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
3.     xmlns:context="http://www.springframework.org/schema/context"  
4.     xsi:schemaLocation="http://www.springframework.org/schema/beans  
5.     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
6.     http://www.springframework.org/schema/context  
7.     http://www.springframework.org/schema/context/spring-context-3.0.xsd">  
8.       
9.     <context:component-scan base-package="test.jersey_spring.demo" />  
10.       
11. </beans>  

 5. 现在可以写类测试了，应当会报错，当使用jackson时

Error

Java代码  

1. 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
