request中文问题

[wdhs]

服务器：resin3.0.8

jsp中：
request.getCharacterEncoding() == "UTF-8"，
String sWords = request.getParameter("words")显示中文正常

但在servlet中：
request.getCharacterEncoding() == null，
response.setCharacterEncoding("utf-8");
out.println(sWords+"<br/>");
out.println(new String(sWords.getBytes("unicode"),"utf-8")+"<br/>");
out.println(new String(sWords.getBytes("gb2312"),"utf-8")+"<br/>");
out.println(new String(sWords.getBytes("ISO8859-1"),"utf-8")+"<br/>");
显示中文都不正常

大虾们帮忙把把脉！谢谢。

莫非servlet不支持

[gln]

试试GBK编码

[xuyang821225]

request.setCharacterEncoding("utf-8");
改成这个试试

好像要先把从HTML页面传来的数据从ISO8859-1转换为byte，然后再转换成需要的编码的

response.setCharacterEncoding("utf-8");你的是这样的，是错的啊！应该是request.setCharacterEncoding("utf-8");

你可以看一下jsp生成的servlet里是怎么设的就行了!

使用filter
web.xml
<filter>
<filter-name>characterfilter</filter-name>
<filter-class>CharacterFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterfilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

CharacterFilter.java

public class CharacterFilter implements Filter {
protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;
public void destroy() {
this.encoding = null;
this.filterConfig = null;
}
public void doFilter(
ServletRequest request,
ServletResponse response,
FilterChain chain) throws IOException, ServletException {
if (ignore || (request.getCharacterEncoding() == null)) {
request.setCharacterEncoding(selectEncoding(request));
}
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");
String value = filterConfig.getInitParameter("ignore");
if (value == null)
this.ignore = true;
else if (value.equalsIgnoreCase("true") || value.equalsIgnoreCase("yes"))
this.ignore = true;
else
this.ignore = false;
}
protected String selectEncoding(ServletRequest request) {
return (this.encoding);
}
public FilterConfig getFilterConfig() {
return filterConfig;
}
public void setFilterConfig(FilterConfig filterConfig) {
this.filterConfig = filterConfig;
}
}

其实这些编码问题我都用一个过滤器就可以搞定。
