现在的问题是，表单提交的中文数据变成了乱码，通过输出测试，提交表单后，在**FORM中就变成了乱码。但是如果从数据库中读取中文返回给JSP，JSP是能够正常显示的。那么这里乱码究竟是在哪个传递过程中出现问题的呢？
网页和配置文件等的编码设置都是UTF-8，不过读取数据库中文数据显示正常，应该不会是这个问题吧。而且我也尝试过改成gb2312，但仍然是乱码，望赐教。

#5
进来学习学习！
#6
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
#7
关注中。。。
#8
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
#9
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？

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);
}
#11
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
#12
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
前台页面和查询结果的字符集保持一致
#13
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
#14
呵呵
这个乱码的问题我见到的比较多
你可以写个过滤器很简单的

#15
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);
#16
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
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
#17
所以说对于中文问题，一个是用过滤器过滤传递过程的编码，再一个还是要注意数据库编码

在web.xml中配置这个就行了啊！

进来学习学习！
#6
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
#7
关注中。。。
#8
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
#9
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？

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);
}
#11
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
#12
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
前台页面和查询结果的字符集保持一致
#13
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
#14
呵呵
这个乱码的问题我见到的比较多
你可以写个过滤器很简单的

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);
#16
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
我在applicationcontext.xml中的数据库设置为
</property>

<value>jdbc:mysql://localhost:3306/bookstore</value>

#17
所以说对于中文问题，一个是用过滤器过滤传递过程的编码，再一个还是要注意数据库编码
