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

不好意思多写了

<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>

如果你这样str = new String(str.getBytes("ISO-8859-1"), "GBK"); 转码。 写出来程序通用性不好，而且每次有中文都要这样，用过虑器好。但只对post方式有效。get方式看， http://www.blogjava.net/chenlb/archive/2007/07/17/130922.html

如果是spring

用spring提供的过虑器,在web.xml里加

	<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

	<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>
