Answer 3

在web.xml中配置这个就行了啊！
<!-- 中文乱码处理 -->
  <filter>
  <filter-name>filter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
  <param-name>encoding</param-name>
  <param-value>GBK</param-value>
  </init-param>
  </filter>

Answer 4

顶四楼,加一个SPRING的过滤器.还有不要忘记页面编码和服务器的编码要一致

Answer 5

我这么加的
  <filter> 
   <filter-name>filter</filter-name> 
   <filter-class>org.springframework.web.filter.CharacterEncodingFilter </filter-class> 
   <init-param> 
   <param-name>encoding</param-name> 
   <param-value>GBK</param-value> 
   </init-param> 
  </filter>
  <filter-mapping>  
   <filter-name>filter</filter-name>  
   <servlet-name>/*</servlet-name>  
  </filter-mapping> 可是仍然是乱码，楼上说的页面编码和服务器的编码要一致，服务器编码是指哪个啊？我在加了这么一段之后，其他地方的编码需要改动么，我现在还是保留UTF-8另外可不可能是post方式提交或request、response的问题呢，我对**FORM获取表单内容的过程不太清楚，它是如何根据名称获取的呢

Answer 6

补充一句，ClientsAction.java 中的insert方法，被注释掉的方法是正常的读取表单内容然后写入数据库中的代码，我为了测试是不是写入数据库的过程中出现了问题，所以将其注释而用指定的中文数据插入测试，结果插入的数据是乱码说明这个过程有问题然后在ClientsForm.java 中，validate方法里加了一句 System.out.println("prince1:"+this.getCname());这是想测试ClientsForm接收表单数据的过程中是否有问题，结果输出的结果也是乱码，说明这个过程也有问题
那该怎么解决呢？

Answer 7

表单提交都是通过servlet调post()或get()方法处理的，再把结果返回到客户端。
有做过滤器吗，写个过滤类，表单提交都先到servlet请求，如果在请求前加个过滤器，将字符都转为中文再进行处理。
public void doFilter(ServletRequest request, ServletResponse response, 
FilterChain chain) throws IOException, ServletException { HttpServletRequest request_1 = (HttpServletRequest) request; 
HttpServletResponse response_1 = (HttpServletResponse) response; // 转换编码，并且加上去缓存 
request_1.setCharacterEncoding("GBK"); 
response_1.setCharacterEncoding("GBK"); 
chain.doFilter(request, response); } 

Answer 8

前台后台服务器都要统一，你的过滤器里怎么是GBK?应该用UTF-8吧

Answer 9

页面上的只是显示的编码吧，并不是请求的编码，后台和request的字符集保持一致就行，
前台页面和查询结果的字符集保持一致

Answer 10

我加了这么一个过滤器，按11楼说的都统一改成UTF-8
结果是表单提交数据到ACTION FORM是正确的，但是ACTIONFORM数据写入数据库的中文还是不正确，一个汉字变成了两个问号

Answer 11

由于Java默认的编码方式是UNICODE，所以用中文易出问题，常用解决：
String s2 = new String(s1.getBytes(“ISO-8859-1”),”GBK”);utf-8解决JSP中文乱码问题，在页面的开始处加：
<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%> <%request.setCharacterEncoding("UTF-8");%>如果仍不能解决问题，还需要这样处理一下：
String msg = request.getParameter("message");
String str=new String(msg.getBytes("ISO-8859-1"),"UTF-8");out.println(st); 

Answer 12

找到问题的原因了，后来的写数据库的乱码问题是数据库设置没有设置编码我在applicationcontext.xml中的数据库设置为 </property>
        <property name="url">
        <value>jdbc:mysql://localhost:3306/bookstore</value>
 </property>现在改成jdbc:mysql://localhost:3306/bbs?useUnicode=true＆amp;characterEncoding=utf-8 就没有问题了这样从页面到服务器到数据库都是统一的UTF-8编码了
