springmvc配置json

配置方案
1、需要导入 jackson-annotations-*.jar , jackson-core-.jar , jackson-databind-.jar  

2、在springmvc中添加配置  

<!-- 用于将对象转换为 JSON  -->  <bean id="stringConverter"  class="org.springframework.http.converter.StringHttpMessageConverter">          <property name="supportedMediaTypes">              <list>                  <value>text/plain;charset=UTF-8</value>              </list>          </property>  </bean>  <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">          <property name="messageConverters">              <list>                  <ref bean="stringConverter" />                  <ref bean="jsonConverter" />              </list>          </property>  </bean>
