主要原因是:页面提交时,使用<contentType:utf-8/>格式,而服务端HttpMessageConverter解码时使用其它格式解码(如:ISO-8859-1)导致
解决方案:在Servlet中设置CharacterEncoding为UTF-8格式。
方法一:在Web.xml中加入Spring的字符集过滤器(已测)
<filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
encoding
字符集,将request字符集设置成encoding指定格式(相当于request.setCharacterEncoding)
forceEncoding
强制字符集设置,主要用来设置response字符集是否也是encoding指定格式
当设置为true时,相当于request.setCharacterEncoding + response.setCharacterEncoding
当设置为false时(默认),相当于request.setCharacterEncoding
加入后相当于在servlet中加入下面代码
request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8");
方法二:手动写Filter(未测)
对每个访问进行拦截,并执行下列代码
request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8");
方法三:设置HttpMessageConverter实现类的解码方式(未测试)
<mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/plain;charset=UTF-8</value> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json; charset=UTF-8</value> <value>application/x-www-form-urlencoded; charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven>
