Struts2 JDBC oracle 乱码问题

Question

用struts提交表单到action在通过调用JDBC到oracle数据库, 输入的中文都是乱码,请高手指教!

Answer 1

页面的编码和数据库的编码不统一。才造成的。
建议加一个编码的过滤器。解决编码问题。新增过滤器类EncodingFilterimport java.io.IOException;
import javax.servlet.*;public class EncodingFilter implements Filter {    private FilterConfig filterConfig = null;
    private String encoding = null;     @Override
    public void destroy() {
         filterConfig = null;
         encoding = null;
     }     @Override
    public void doFilter(ServletRequest request, ServletResponse response,
             FilterChain filterChain) throws IOException, ServletException {
        if (request.getCharacterEncoding() == null) {
            if (encoding != null) {
                 request.setCharacterEncoding(encoding);
             }
             filterChain.doFilter(request, response);
         }
     }     @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        this.filterConfig = filterConfig;
        this.encoding = filterConfig.getInitParameter("encoding");
     }
}
web.xml中加入  <filter>
      <filter-name>EncodingFilter</filter-name>
      <filter-class>EncodingFilter</filter-class>
      <init-param>
          <param-name>encoding</param-name>
          <param-value>UTF-8</param-value>
      </init-param>
  </filter>
  <filter-mapping>
      <filter-name>EncodingFilter</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
jsp页面中设置pageEncoding="UTF-8" ，表单提交方法method="post"
