一、框架版本
1 2 3 4 5 6 7 | <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" /> </bean> </mvc:message-converters> </mvc:annotation-driven> |
2、实现AbstractHttpMessageConverter抽象类（未解决）

该方法解决了返回乱码问题，但是easyui无法显示数据（有数据但是显示为空，原因不明）

3、@RequestMapping添加produces = "text/html;charset=UTF-8"，在Controller或Action添加均可（解决问题）
