动态调用JavaBean的set方法（续）

public Object setProperty(String ClassPath,HttpServletRequest req)
{
    try{
        Class ClassName=Class.forName(ClassPath);
        Object ClassInstance=ClassName.newInstance();
        Method[] MethToExe=ClassName.getDeclaredMethods();
        for(int i=0;i<MethToExe.length;i++)
        {                               
            String MethName=MethToExe[i].getName();
            if(MethName.substring(0, 3).equals("set"))
            {                           
                String Parameter=req.getParameter(MethName.substring(3));
                if(Parameter==null||Parameter.trim().equals(""))
                {
                    continue;
                }else{
                    Object arglist[] = new Object[1];
                    arglist[0] = new String(Parameter);                       
                    MethToExe[i].invoke(ClassInstance, arglist);
                }
            }
        }
        return ClassInstance;
    }catch(Exception e)
    {
        e.printStackTrace();
    }
    return null;       
}
