maven pom配置，注意增加json的处理jar包

  <dependency>

    <groupId>com.fasterxml.jackson.core</groupId>

    <artifactId>jackson-databind</artifactId>

    <version>2.4.4</version>

  </dependency>

web.xml dispathserver配置

  <servlet>

    <servlet-name>example</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

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

  </servlet>

  <servlet-mapping>

      <servlet-name>example</servlet-name>

      <url-pattern>/*</url-pattern>

  </servlet-mapping>

*-servlet.xml中进行基本的mvc配置

<context:component-scan base-package="com.zume100" >

</context:component-scan>

 

<mvc:annotation-driven /> 

 

    <bean id="example" class="com.zume100.Example">

    </bean>

controller用@RestController注解，表示@responsebody和@controller的组合
