jsp中split的使用问题!!!谢谢!!
没有用过split函数,这是第一次用,出现如下问题,请指教是怎么回事呢?
谢谢!!!
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 7 in the jsp file: /cyhtgl0520/htmod.jsp
Generated servlet error:
[javac] Compiling 1 source file
C:\Tomcat 5.0\work\Catalina\localhost\_\org\apache\jsp\cyhtgl0520\htmod_jsp.java:116: cannot find symbol
symbol : method Split(java.lang.String,java.lang.String)
location: class org.apache.jsp.cyhtgl0520.htmod_jsp
myArr=Split(PayDate, "| ");
------解决方案--------------------1、如果用“.”作为分隔的话,必须是如下写法:String.split( "\\. "),这样才能正确的分隔开,不能用String.split( ". ");
2、如果用“|”作为分隔的话,必须是如下写法:String.split( "\\| "),这样才能正确的分隔开,不能用String.split( "| ");
“.”和“|”都是转义字符,必须得加 "\\ ";
3、如果在一个字符串中有多个分隔符,可以用“|”作为连字符,比如:“acount=? and uu =? or n=?”,把三个都分隔出来,可以用String.split( "and|or ");
------解决方案--------------------拆分成String一维数组后循环输出即可。
<%@ page import= "java.sql.*,java.text.*,java.lang.String "%>
<%@include file= "conn.jsp "%>
<%
String Hmod = new String(request.getParameter( "HNo ").getBytes(
"ISO-8859-1 "));
String PayDate = " ";
String sql = "select * from InfoHt where HNo= ' " + Hmod + " ' ";
ResultSet rs = sts.executeQuery(sql);
try {
while (rs.next()) {
PayDate = rs.getString( "PayDate ").trim();
}
String[] myArr = PayDate.split( "\\| ");
for(int i=0;i <myArr.length;i++)
{
out.println(myArr[i]);
}
rs.close();
sts.close();
} catch (Exception e) {
out.println(e.getMessage());
}
%>
------解决方案--------------------代码没有问题啊。。。
比如下面的测试:
public static void main(String[] args)
{
String PayDate = "20070501|20070601|20070701 ";
String[] myArr = PayDate.split( "\\| ");
for (int i = 0; i < myArr.length; i++)
{
System.out.println(myArr[i]);
}
}
输出:
20070501
20070601
20070701
------解决方案--------------------lz能确定:PayDate = rs.getString( "PayDate ").trim(); 能得到值吗?
