將用戶定義的java對象傳遞給速度scriptengine

Question

即時使用速度模板和CQ5。我已安裝的velocity scriptengine可識別預定義的CQ對象。我想知道如何將用戶定義的java對象傳遞給速度腳本引擎。 我想類似這樣的東西： http://groovy.codehaus.org/JSR+223+Scripting+with+Groovy

但它不work..Kindly幫我解決這個情況提前

感謝

你只需要使用VelocityContext傳遞對象參數一樣context.put("name_of_parameter", yourOBject); 在我的例子中，test.temalate，$person.address表示person對象的平均調用地址getter方法。

示例：試試如下

Person.java 公共類Person { 私人字符串名稱; 私人字符串地址;

public Person(String name, String address) { 
     this.name = name; 
     this.address = address; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setAddress(String address) { 
     this.address = address; 
    } 

    public String getAddress() { 
     return address; 
    } 
} 

Test.java

import java.io.StringWriter; 

import org.apache.velocity.Template; 
import org.apache.velocity.VelocityContext; 
import org.apache.velocity.app.VelocityEngine; 


public class Test { 
    public static void main(String[] args) { 
     VelocityEngine ve = new VelocityEngine(); 
     ve.init(); 
     Template template = ve.getTemplate("test.template"); 
     VelocityContext context = new VelocityContext(); 
     context.put("person", new Person("Jhon", "London")); 
     StringWriter writer = new StringWriter(); 
     template.merge(context, writer); 
     System.out.println(writer.toString()); 
    } 
} 

test.template

<table> 
    <tr> 
     <td>Name</td> 
     <td>$person.name</td> 
    </tr> 
    <tr> 
     <td>Address</td> 
     <td>$person.address</td> 
    </tr> 
</table> 

你會得到如下輸出。

<table> 
    <tr> 
     <td>Name</td> 
     <td>Jhon</td> 
    </tr> 
    <tr> 
     <td>Address</td> 
     <td>London</td> 
    </tr> 
</table>
