org.apache.tomcat.util.http.Parameters processParameters 警告: Parameters: Character decoding failed. Parameter 'id' with value '%u8BA2%u5355' has been ignored. Note that the name and value quoted here may corrupted due to the failed decoding. Use debug level logging to see the original, non-corrupted values. Enter Servlet Get Method.. OK： 2013-1-16 10:35:49 org.apache.catalina.core.StandardWrapperValve invoke 严重: Servlet.service() for servlet suggest threw exception java.lang.NullPointerException at com.ont.demo.suggest.doGet(suggest.java:25) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:619) 解决方法：在传递参数前将中文参数进行两次编码，jsp页面获取参数后对中文参数进行一次解码，中文参数就不会变为乱码了！ 参考例子： 复制代码 代码如下:www.CuoXIn.com <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ page import="java.net.*" %> <% String str0=""; String str1=""; if(request.getParameter("param0")!=null){ str0=request.getParameter("param0");//直接获取中文参数 } try{ if(request.getParameter("param1")!=null){ str1=URLDecoder.decode(request.getParameter("param1"),"utf-8");//对中文参数进行解码 } }catch(Exception e){ e.printStackTrace(); } %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript"> var str="你好"; function test0(){ window.location="Test.jsp?param0="+str;//直接传递中文参数 } function test1(){ window.location="Test.jsp?param1="+encodeURI(encodeURI(str));//对中文参数进行双层编码后再传递 } </script> </head> <body> <input value=<%=str0 %>> <input type="button" value="乱码" onclick="test0()"><br> <input value=<%=str1 %>> <input type="button" value="正常" onclick="test1()"> </body> </html> （编辑：聊城站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
