Spring MVC中文乱码解决方案
web项目和SpringMvc集成的时候出现中文乱码
post:jsp页面
<body>
${username}
<form action="myController" method="post">
<input name="username" type="text" >
<input type="submit" value="提交" >
</form>
</body>
java后台:
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
throws Exception {
String username = request.getParameter("username");
System.out.println(username);
ModelAndView model = new ModelAndView();
model.addObject("username", username);
System.out.println(username);
return model;
}
出现乱码:æ¯å¦æçå
解决方式:在web.xml文件里面添加filter,注意这种方式只能解决post方式的乱码
<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> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

get:乱码
ajax,a标签,form,浏览器地址栏输入的参数都有可能出现get方式的请求
这种方式在和具体服务器的配置有关
比如tomcat解决方式
在server.xml里面
将
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" />
修改成
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>
