NVelocity的几种写法

1、

        IList<UserInfo> listUsers = new List<UserInfo>();

        UserInfo objUser = new UserInfo();
        objUser.Name = "测试员一";
        objUser.Sex = "男";
        objUser.City = "深圳";
        listUsers.Add(objUser);

        objUser = new UserInfo();
        objUser.Name = "测试员二";
        objUser.Sex = "女";
        objUser.City = "北京";
        listUsers.Add(objUser);

        objUser = new UserInfo();
        objUser.Name = "测试员三";
        objUser.Sex = "男";
        objUser.City = "非洲";
        listUsers.Add(objUser);

        IList<string> listAssembly = new List<string>();
        // 添加程序集名称
        listAssembly.Add("LibTest");

        VelocityEngine vltEngine = new VelocityEngine();
        vltEngine.SetProperty(RuntimeConstants.RESOURCE_LOADER, "assembly");
        vltEngine.SetProperty("assembly.resource.loader.class", "NVelocity.Runtime.Resource.Loader.AssemblyResourceLoader; NVelocity"); // 固定写法- -!
        vltEngine.SetProperty("assembly.resource.loader.assembly", listAssembly);
        vltEngine.Init();

        VelocityContext vltContext = new VelocityContext();
        vltContext.Put("PageTitle", "资源模板例子");
        vltContext.Put("ListUsers", listUsers);

        Template vltTemplate = vltEngine.GetTemplate("LibTest.Resources.Default.htm");
        System.IO.StringWriter vltWriter = new System.IO.StringWriter();
        vltTemplate.Merge(vltContext, vltWriter);

        Response.Write(vltWriter.GetStringBuilder().ToString());

2、

        //创建NVelocity引擎的实例对象
        VelocityEngine velocity = new VelocityEngine();
        //初始化该实例对象
        ExtendedProperties props = new ExtendedProperties();
        props.AddProperty(RuntimeConstants.RESOURCE_LOADER, "file");
        //可换成：props.AddProperty("resouce.loader","file"),以下的同道理
        props.AddProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, Server.MapPath("~/Template/"));
        props.AddProperty(RuntimeConstants.INPUT_ENCODING, "gb2312");
        props.AddProperty(RuntimeConstants.OUTPUT_ENCODING, "gb2312");
        velocity.Init(props);
        //从文件中读取模板
        Template temp = velocity.GetTemplate("Default.htm");

        IContext vltContext = new VelocityContext();
        vltContext.Put("PageTitle", "资源模板例子");
        vltContext.Put("ListUsers", listUsers);
        //合并模板
        StringWriter writer = new StringWriter();
        //velocity.MergeTemplate(context, writer);
        temp.Merge(vltContext, writer);
        //输入
        Response.Write(writer.GetStringBuilder().ToString());

 

3、生成静态文件abc.htm

 

        //创建NVelocity引擎的实例对象
        VelocityEngine velocity = new VelocityEngine();
        //初始化该实例对象
        ExtendedProperties props = new ExtendedProperties();
        props.AddProperty(RuntimeConstants.RESOURCE_LOADER, "file");
        props.AddProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, Path.GetDirectoryName(Request.PhysicalPath) + "/Template/");
        props.AddProperty(RuntimeConstants.INPUT_ENCODING, "gb2312");
        props.AddProperty(RuntimeConstants.OUTPUT_ENCODING, "gb2312");
        velocity.Init(props); 
        //从文件中读取模板
        Template temp = velocity.GetTemplate("Default.htm");
        VelocityContext vltContext = new VelocityContext();
        vltContext.Put("PageTitle", "资源模板例子");
        vltContext.Put("ListUsers", listUsers);
        //合并模板
        StringWriter writer = new StringWriter();
        //velocity.MergeTemplate(context, writer);
        temp.Merge(vltContext, writer);

        //Template vltTemplate = velocity.GetTemplate("LibTest.Resources.Default.htm");
        //System.IO.StringWriter vltWriter = new System.IO.StringWriter();
        //temp.Merge(vltContext, vltWriter);
        //生成静态页
        using (StreamWriter writer2 = new StreamWriter(Server.MapPath("") + "/abc.htm", false, Encoding.UTF8, 200))
        {
            writer2.Write(writer);
            writer2.Flush();
            writer2.Close();
        }

 

4、

       VelocityEngine vltEngine = new VelocityEngine();
        vltEngine.SetProperty(RuntimeConstants.RESOURCE_LOADER, "file");
        vltEngine.SetProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, Server.MapPath(""));
        vltEngine.Init();

        VelocityContext vltContext = new VelocityContext();
        vltContext.Put("PageTitle", "文件模板例子");
        vltContext.Put("ListUsers", listUsers);
        vltContext.Put("ArticleManage", new ArticleManage());

        Template vltTemplate = vltEngine.GetTemplate("Default.htm");
        System.IO.StringWriter vltWriter = new System.IO.StringWriter();
        vltTemplate.Merge(vltContext, vltWriter);

        Response.Write(vltWriter.GetStringBuilder().ToString());

 

5、模版文件Default.htm为：

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>$PageTitle</title>
</head>
<body>
#foreach($u in $ListUsers)
#beforeall
    用户列表<br />
    ---<br />
    <table border="0" cellpadding="10" cellspacing="10">
    <tr>
        <td>昵称</td>
        <td>性别</td>
        <td>城市</td>
    </tr>
#each
    <tr>
        <td>$u.Name</td>
        <td>$u.Sex</td>
        <td>$u.City</td>
    </tr>
#afterall
    </table>
#nodata
    暂无用户资料
#end
