1.在web.xml中加入一个过滤器和过滤范围的配置
<filter>
<filter-name>encoding</filter-name>
<filter-class>com.guet.cab.base.Filter.EncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2.com.guet.cab.base.Filter.EncodingFilter指明其具体实现的包名，第二个配置指明其监听所有的请求。
3.字符编码过滤的具体实现为
package com.guet.cab.base.Filter;
import java.io.*;
import javax.servlet.*;
public class EncodingFilter implements Filter {
public void init(FilterConfig filterConfig) throws ServletException {
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
try {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
} catch (Exception e) {
}
chain.doFilter(request, response);
}
public void destroy() {
}
};
