Spring的Rest服务

1、web.xml 增加配置

   <servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

2、增加 WEB-INF/spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

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

	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="

	http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

 
	
	<mvc:annotation-driven />
	<mvc:default-servlet-handler/>   
	
	<context:component-scan base-package="com.test"/>

	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="jsonHttpMessageConverter"/>
				<ref bean="stringHttpMessageConverter"/>
			</list>
		</property>
	</bean>
	<bean id="jsonHttpMessageConverter" 
		class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
	
	 <property name="supportedMediaTypes">    
        <list>    
            <value>application/json;charset=UTF-8</value>    
       </list>    
    </property> 
	</bean>
	
	
	
	<bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter">
				 <property name="supportedMediaTypes">    
			        <list>    
			            <value>application/json;charset=UTF-8</value>    
			       </list>    
			    </property> 
			</bean>


</beans>

3\新引入jar
jackson-all-1.9.11.jar
jackson-core-2.0.4.jar
asm-commons-3.3.jar
asm-util-2.2.2.jar
