这是我的一个项目的配置

Set Character Encoding
com.****.EncodingFilter

encoding
UTF-8



Set Character Encoding
/*

EncodingFilter 的内容是

public class EncodingFilter implements Filter {

private FilterConfig filterConfig = null;
private String encoding = null;
private boolean ignore = true;

public final void init(final FilterConfig arg0) throws ServletException {
    this.filterConfig = arg0;
    this.encoding = filterConfig.getInitParameter("encoding");
    String value = filterConfig.getInitParameter("ignore");
    if (value == null) {
        this.ignore = true;
    } else if (value.equalsIgnoreCase("true")) {
        this.ignore = true;
    } else if (value.equalsIgnoreCase("yes")) {
        this.ignore = true;
    } else {
        this.ignore = false;
    }
}

public final void doFilter(final ServletRequest request,
        final ServletResponse response, final FilterChain chain)
        throws IOException, ServletException {
    if (ignore || (request.getCharacterEncoding() == null)) {
        String encoding1 = selectEncoding(request);
        if (encoding1 != null) {
            request.setCharacterEncoding(encoding1);
        }
    }
    try {
        chain.doFilter(request, response);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
    //如果你没用hibernate 把这部分删除就行了      HibernateSessionFactory.closeSession();
        } catch (Exception e) {
        }
    }
}

public final void destroy() {
    this.encoding = null;
    this.filterConfig = null;

}

protected final String selectEncoding(final ServletRequest request) {
    return (this.encoding);
}

}
都晚上了还没弄好啊，估计急坏了吧 :wink:
