SpringMVC 乱码处理

SpringMVC @ResponseBody乱码处理：

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

 

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 types = new ArrayList();
			types.add(mediaType);
			((StringHttpMessageConverter) bean).setSupportedMediaTypes(types);
		}
		return bean;
	}

	public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
		return bean;
	}

}
