String s1 = request.getParameter("write");
String s2 = request.getParameter("ui");
if(s2.equals("id")){
String s3 = "ID";
System.out.println(JDBCConnect.searchData(s1,s3));
return;
}
else if(s2.equals("serivceid")){
String s3 = "SERIVCEID";
System.out.println(JDBCConnect.searchData(s1, s3));
return;
}else if(s2.equals("syskey")){
String s3 = "SYSKEY";
System.out.println(JDBCConnect.searchData(s1, s3));
return;
}else if(s2.equals("sysname")){
String s3 = "SYSNAME";
System.out.println(JDBCConnect.searchData(s1, s3));

return;
}else if(s2.equals("fromtype")){
String s3 = "FROMTYPE";
System.out.println(JDBCConnect.searchData(s1, s3));
return;
}else if(s2.equals("totype")){
String s3 = "TOTYPE";
System.out.println(JDBCConnect.searchData(s1, s3));
return;
}else if(s2.equals("iserror")){
String s3 = "ISERROR";
System.out.println(JDBCConnect.searchData(s1, s3));
return;
}

Answer 1

最简单的，你能快速理解的
serverlet里面跳转的页面后面&kd=value
jsp里面<% String value = request.getParameter(key); %>

Answer 2

request.setAttrubute()

追问

可以具体点吗？

这个就是用这个将数据放在里面，到你的那个jsp页面使用El表达式取出来
