Question

我在使用ap：commandbutton.when在p：commandButton中更新值时出现问题，我设置ajax =“true”所有事情都没问题，但是当我设置ajax =“false”时，p：inputText中的值不编码，在下一页显示我ÙØ±ÛÙ。或者发送到mysql数据库时。我正在使用Filter，但我的问题无法解决。

请帮助我感谢

我应该使用Filter来解决这个问题。

    <filter>
    <filter-name>EncodingFilter</filter-name>
    <filter-class>myengineer.EncodingFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>EncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

和java类过滤器

package myengineer;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**

 */
public class EncodingFilter implements Filter{
                   ///===================================================================================
public void init(FilterConfig config) throws ServletException {
    //No-op
}
    ///===================================================================================
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain       chain) 
                                                       throws IOException,     ServletException {
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);
    }
    ///==================================================================================
    public void destroy() {
        //No-op
    }    
    ///===================================================================================
}

Primefaces ajax charset
