关于form提交乱码（SpringMVC）

解决方法：

1>web.xml文件中配置：  <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> 

2>对于单个字符串，如搜索关键字，可以用：String newstr = new String(oleStr.getBytes("ISO-8859-1"),"utf-8");
