由于Struts框架直接把表单数据发送给了ActionForm所以这里面没有对HttpRequestServlet进行SetCharacterEncoding所以默认是按照ISO(参见Tomcat 源代码中的orgnnectorHttpRequestBase中的protected void parseParameters()方法)
解决的方法就是在表单提交到ActionForm之前对request进行编码
第一种方法就是写一个过滤器对所有请求进行过滤
过滤器代码
package ricohgtisothersprofilefilters;
import javaioIOException;
import javaxservletFilter;
import javaxservletFilterChain;
import javaxservletFilterConfig;
import javaxservletServletException;
import javaxservletServletRequest;
import javaxservletServletResponse;
public class SetCharacterEncodingFilter implements Filter {
private String encoding;
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Autogenerated method stub
thisencoding=filterConfiggetInitParameter(encoding);
}
public void doFilter(ServletRequest request ServletResponse response
FilterChain chain) throws IOException ServletException {
// TODO Autogenerated method stub
requestsetCharacterEncoding(thisencoding);
chaindoFilter(requestresponse);
}
public void destroy() {
// TODO Autogenerated method stub
}
}
配置文件webxml
<filter>
<filtername>SetCharacterEncodingFilter</filtername>
<filterclass>ricohgtisothersprofilefiltersSetCharacterEncodingFilter</filterclass>
<initparam>
<paramname>encoding</paramname>
<paramvalue>utf</paramvalue>
</initparam>
</filter>
<filtermapping>
<filtername>SetCharacterEncodingFilter</filtername>
<urlpattern>/*</urlpattern>
</filtermapping>
第二种方法是替换默认的控制器orgapachestrutsactionActionServlet
子类代码
package ricohgtintrollers;
import javaioIOException;
import javaxservletServletException;
import javaxservlethttpHttpServletRequest;
import javaxservlethttpHttpServletResponse;
import orgapachestrutsactionActionServlet;
public class SetEncodingActionServlet extends ActionServlet {
protected void process(HttpServletRequest request HttpServletResponse response) throws IOException ServletException {
// TODO Autogenerated method stub
String encoding = getInitParameter(encoding);
requestsetCharacterEncoding(encoding);
superprocess(request response);
}
}
配置文件webxml
<servlet>
<servletname>testAction</servletname>
<servletclass>ricohgtintrollersSetEncodingActionServlet</servletclass>
<initparam>
<paramname>config</paramname>
<paramvalue>/WEBINF/strutsconfigxml</paramvalue>
</initparam>
<initparam>
<paramname>encoding</paramname>
<paramvalue>utf</paramvalue>
</initparam>
<loadonstartup></loadonstartup>
</servlet>
<servletmapping>
<servletname>testAction</servletname>
<urlpattern>*testdo</urlpattern>
</servletmapping>
此例凡是通过*testdo来请求的数据都会经过参数encoding设定的值来编码
