利用xml+xsl快速生成大量JSP的常用代码的方法.

 

参考Jbuilder的Servlet向导来使用xml+xsl产生JSP的常用代码。

xml样本:

 

<?xml version="1.0" encoding="GB2312"?>
<?xml-stylesheet type="text/xsl" href="jspram.xsl"?>
<jsp xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="jspsrcgen.xsd">
 <param>
  <variable>rloginusername</variable>
  <name>loginusername</name>
  <type>String</type>
  <src>request</src>
  <default>lizongbo</default>
  <desc>用户的登录名</desc>
 </param>
 <param>
  <variable>clastlogintime</variable>
  <name>lastlogintime</name>
  <type>long</type>
  <src>cookie</src>
  <default>0</default>
  <desc>用户最近一次的登录时间</desc>
 </param>
 <param>
  <variable>suserpass</variable>
  <name>userpass</name>
  <type>String</type>
  <src>session</src>
  <default>password</default>
  <desc>存放在session里的密码</desc>
 </param>
</jsp>

 

xsl文件略。

生成好的java代码：

 

 

 

我封装的JSPUtil代码片断：

 
  public static string getparameter(httpservletrequest request, string name,
                                    string defval) {
    string param = request.getparameter(name);
    return (param != null ? param : defval);
  }
 
  public static boolean getparameter(httpservletrequest request, string name,
                                     boolean defval) {
    string bv = request.getparameter(name);
    return bv == null ? defval : parseboolean(bv);
 
  }
 
  public static double getparameter(httpservletrequest request, string name,
                                    double defval) {
    return parsedouble(request.getparameter(name), defval);
  }
 
  public static float getparameter(httpservletrequest request, string name,
                                   float defval) {
    return parsefloat(request.getparameter(name), defval);
  }
 
  public static int getparameter(httpservletrequest request, string name,
                                 int defval) {
    return parseint(request.getparameter(name), defval);
  }
 
  public static long getparameter(httpservletrequest request, string name,
                                  long defval) {
    return parselong(request.getparameter(name), defval);
  }
 
  public static short getparameter(httpservletrequest request, string name,
                                   short defval) {
    return parseshort(request.getparameter(name), defval);
  }
