spring mvc 中文乱码问题解决

在eclipse环境里，页面传输数据的时候通常用ISO-8859-1这个字符集
可以用 str = new String(str.getBytes("ISO-8859-1"), "GBK"); 转码
str是你页面得到的字符串，后面的表示从"ISO-8859-1"转到"GBK"，或者你转成别的也可以


用spring提供的过虑器,在web.xml里加
Java代码 

<filter>  
  <filter-name>Set Character Encoding</filter-name>  
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
  <init-param>  
    <param-name>encoding</param-name>  
    <param-value>utf8</param-value>  
  </init-param>  
</filter>  
 <filter-mapping>  
    <filter-name>Set Character Encoding</filter-name>  
    <url-pattern>/*</url-pattern>  
 </filter-mapping>

 


如没用spring,用tomcat里面的例子(在webapps\servlets-examples\WEB-INF\classes\里把filters目录放到你的classer\下,其实只要SetCharacterEncodingFilter就可以了,同样在web.xml里加
Java代码 

<filter>  
  <filter-name>Set Character Encoding</filter-name>  
  <filter-class>filters.SetCharacterEncodingFilter</filter-class>  
  <init-param>  
    <param-name>encoding</param-name>  
    <param-value>utf8</param-value>  
  </init-param>  
</filter>  
 <filter-mapping>  
    <filter-name>Set Character Encoding</filter-name>  
    <url-pattern>/*</url-pattern>  
 </filter-mapping>
