freemarker乱码问题解决方案

一.spring mvc方面

1.在拦截器中

public class CustomInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)throws Exception {request.setCharacterEncoding("utf-8");response.setContentType("text/html;charset=utf-8");return true;}}

2.在controller的action中return "string".getbyte("utf-8")进行转码。

@RequestMapping("test")@ResponseBodypublic byte[] test(HttpServletResponse response) {log.info("hello");try {return "你好".getBytes("utf-8");} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();}return "error".getBytes();}

另外，此处返回值byte[]不能写成string，否则也会出现乱码问题。

二.freemarker方面。

<!-- freemarker的配置 --><bean id="freemarkerConfigurer"class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"><property name="templateLoaderPath" value="freemarker" /><property name="defaultEncoding" value="UTF-8" /><property name="freemarkerSettings"><props><prop key="template_update_delay">0</prop><prop key="locale">zh_CN</prop><prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop><prop key="date_format">yyyy-MM-dd</prop><prop key="number_format">#.##</prop></props></property></bean><!-- FreeMarker视图解析 如返回userinfo。。在这里配置后缀名ftl和视图解析器。。 --><bean id="viewResolver"class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"><property name="viewClass" value="bp.common.CustomFreeMarkerView" /><property name="suffix" value=".html" /><property name="contentType" value="text/html;charset=UTF-8" /><property name="exposeRequestAttributes" value="true" /><property name="exposeSessionAttributes" value="true" /><property name="exposeSpringMacroHelpers" value="true" /><property name="allowSessionOverride" value="true" /><property name="redirectHttp10Compatible" value="false" /></bean>

OK~
