import java.io.StringWriter;
import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.Velocity;
public class VelocityBaseTest {
public static void main(String[] args) {

//也可使用properites設定，這邊練習不需要
//Velocity.init("properties/velocity.properties");
// 取得velocity上下文
VelocityContext context = new VelocityContext();
context.put("name", "Daniel");
Template template = Velocity.getTemplate("template/hello.vm");
StringWriter writer = new StringWriter();
template.merge(context, writer);

}
}
}
hello.vm：
<html>
<head></head>
<body>
HELLO! $name,Welcome to velocity!
</body>
</html>
Velocity.properties：
#Velocity.properties配置示例
# 如果需要系統從WEB-INF/classes路徑載入Velocity的範本檔，取消下兩行的注釋
#resource.loader=class
#class.resource.loader.class=org.apache.Velocity.runtime.resource.loader.ClasspathResourceLoader
#如需禁止系統通過檔案系統載入範本檔，注釋如下兩行
resource.loader=file
file.resource.loader.path=D:\practice\VJ\workspace\velocitytest\template
#確定從何處載入velocity的範本檔
file.resource.loader.cache=false
input.encoding=gb2312
output.encoding=gb2312
產出的檔案：
hello.html:
<html>
<head></head>
<body>
HELLO! sea,Welcome to velocity!
</body>
</html>
