struts2有时候会莫名其妙的出现中文乱码,小伙伴们知道要怎么解决吗?下面听小编来说说吧。
配置在web.xml里
<!-- 乱码过滤器 --> <filter> <filter-name>CharaterencodeFilter</filter-name> <filter-class>com.CharaterEncodeFilter</filter-class> </filter> <filter-mapping> <filter-name>CharaterencodeFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
对应的类
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; import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter; public class CharaterEncodeFilter implements Filter { private FilterConfig config = null; public void destroy() { this.config = config; } 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 init(FilterConfig arg0) throws ServletException { config = null; } }
