json乱码处理

（1）@RequestMapping配置produce属性

@RequestMapping(value = "/test",produces = "application/json;charset=utf-8")

（2）MVC配置文件中配置

<mvc:annotation-driven>
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
              <constructor-arg value="UTF-8"/>
        </bean>
        <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
        <property name="failOnEmptyBeans" value="false"/>
        </bean>
        </bean>
</mvc:annotation-driven>
