原理:将StringHttpMessageConverter的默认编码设为UTF-8

?

方法1(推荐,参考自springside):

? ?配置spring-mvc.xml

<mvc:annotation-driven>  <mvc:message-converters register-defaults="true">    <!-- 将StringHttpMessageConverter的默认编码设为UTF-8 -->    <bean class="org.springframework.http.converter.StringHttpMessageConverter">      <constructor-arg value="UTF-8" />    </bean>  </mvc:message-converters></mvc:annotation-driven>

?

其他方法:?

方法2:

HttpServletResponse resp = (HttpServletResponse)response;resp.setHeader("Cache-Control","no-cache");resp.setContentType("application/json;charset=UTF-8");resp.setCharacterEncoding("UTF-8");PrintWriter writer = resp.getWriter();writer.write(json);

?

方法3:

@RequestMapping(value="/test",produces="text/plain;charset=UTF-8") @ResponseBody

?

?

方法4:

? ?重写BeanPostProcessor,并配置到spring-mvc.xml

public class BeanPostProcessorUtf8 implements BeanPostProcessor {	public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {		if (bean instanceof StringHttpMessageConverter) {			MediaType mediaType = new MediaType("text", "plain", Charset.forName("UTF-8"));			List<MediaType> types = new ArrayList<MediaType>();			types.add(mediaType);			((StringHttpMessageConverter) bean).setSupportedMediaTypes(types);		}		return bean;	}	public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {		return bean;	}}
<bean id="beanPostProcessor" class="com.xxx.yyy.BeanPostProcessorUtf8" />
