客户端用GET方式请求SpringMVC时，如果用采用如下方式则中文没有出现乱码：

http://127.0.0.1:8080/SpringMVCHibernate4/rest/user/getUserById0/100-张三@RequestMapping(value="/getUserById0/{id}-{name}",method=RequestMethod.GET)@ResponseBody public String getUserById0(@PathVariable Long id, @PathVariable("name")String userName) {User user = new User();user.setUserName(userName);user.setId(id);return GsonUtil.toJson(user);}

但是如果采用如下方式则中文会出现乱码：

http://127.0.0.1:8080/SpringMVCHibernate4/rest/user/getUserById2?id=100&name=张三@RequestMapping(value="/getUserById2",method=RequestMethod.GET)@ResponseBodypublic  String getUserById2(@RequestParam Long id,     RequestParam("name") String userName) {    User user = new User();    user.setUserName(userName);//乱码    user.setId(id);    return GsonUtil.toJson(user);}

web.xml配置了字符编码过滤器，但是依然是乱码：

<filter>    <filter-name>encodingFilter</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>encodingFilter</filter-name>    <url-pattern>/*</url-pattern></filter-mapping>

最终解决办法：修改tomcat默认编码（ISO-8859-1）方法，修改tomcat根目录的conf下的server.xml,Connector元素添加URIEncoding="UTF-8"属性，如下所示：

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1"  redirectPort="8443" URIEncoding="UTF-8" />
