先写一个pojo提供测试Book.java

package org.test;
    
    import java.util.Date;
    
    public class Book {
    	
    	private String bookid;//id
    	private String bookname;//书名
    	private Date publishDate;//出版日期
    	private int bookprice;//价格
    	
    	public String getBookid() {
    		return bookid;
    	}
    	public String getBookname() {
    		return bookname;
    	}
    	public Date getPublishDate() {
    		return publishDate;
    	}
    	public int getBookprice() {
    		return bookprice;
    	}
    	public void setBookid(String bookid) {
    		this.bookid = bookid;
    	}
    	public void setBookname(String bookname) {
    		this.bookname = bookname;
    	}
    	public void setPublishDate(Date publishDate) {
    		this.publishDate = publishDate;
    	}
    	public void setBookprice(int bookprice) {
    		this.bookprice = bookprice;
    	}
    	
    
    }

模版文件：book.vm

<html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>
    我的第一个模版，哈哈
    <table border="1px">
    <th>书名</th>
    <th>价格</th>
    <th>出版日期</th>
    #foreach( $book in $list )
    <tr>
      <td>$book.bookname</td>
      <td>$book.bookprice </td>
      <td>$book.publishDate </td>
    </tr>
    #end
    <table>
    </body>
    </html>

模版文件：book2.vm

<html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>
    
    <table border="1px">

    <th>价格</th>

    #foreach( $book in $mylist )
    <tr>
      <td>$book.getBookname()</td>
      <td>$book.getBookprice() </td>
      <td>${book.getPublishDate()} </td>
    </tr>
    #end
    <table>
    
    <br>其他调用方式：注意context.put("mylist", getBooks());中放入变量的名称是mylist，
    如果换成list就取不到值,但是在book.vm中用的是list就可以取到值，可能Velocity认为第一个容器名称作为
    唯一的名称吧，在这里我第一次使用的是mylist，所以就认为是mylist，好像和context.put("mylist", getBooks())没有关系；
    取不到值的velocity表达式将显示表达式本身，除非，你在$符号后加!,
    这样在取不到值的情况下，将显示空字符串""<br>
    $mylist[0]<br>
    $mylist[0].getBookname()<br><input type="text" name="price" value="$!mylist[0].getBookname()"/><br>

    变量中的变量计算结果：$defobj
    
    ##宏定义，类似JAVA中定义一个方法
    #macro( tablerows $color $somelist )
    	#foreach( $something in $somelist )

    	#end

    #set( $color = "blue" )
    <table>
        #tablerows( $color $greatlakes )
    </table>
    
    ##反斜杠使用
    #set($xie = "反斜杠文字")
    $xie，'$xie'，"$xie";;;\$xie，\\$xie，\\\$xie
    
    \#if( $xie=="反斜杠文字" )
        语法中'#'的转义
    \#end
    #if( $xie=="反斜杠文字" )
        语法中'#'的转义
    #end
    
    </body>
    </html>
    
    引入其他模版，如果改变根路径，记得这里也要改变，如下:
    ##parse("bin/org/test/book.vm") ##file.resource.loader.path=.或/
    #parse("book.vm")  ##file.resource.loader.path=D:/MyProject/my-workSpace/Mytest/bin/org/test

运行VelocityTestUtil

控制台打印：

对比输出结果，Velocity的配置，调用，模版语法都很清楚明了了。
