Spring MVC 返回JSOn数据配置

1.spring-mvc-servlet.xml配置

  <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
            	<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
               <!--   <ref bean="mappingJacksonHttpMessageConverter" />-->
            </list>
        </property>
    </bean>

    
        
   
   <mvc:annotation-driven />

2，加载JackJSOn依赖

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.7.4</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.7.4</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.7.4</version>
</dependency>

3，使用注解@ResponseBody

package gsc.mvc.sping.test;

import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import gsc.mvc.sping.bean.User;
@Controller
@RequestMapping("/user")
public class UserControl {
	@RequestMapping(value="{name}", method = RequestMethod.GET,produces = "application/json;charset=UTF-8")
	   public @ResponseBody User getUser(@PathVariable String name) {

	      User user = new User();

	      user.setName(name);
	      user.setId(1224);
	      return user;
	   }

}
