本文介绍了一个使用Tapestry框架实现页面间不同类型变量传递的例子。通过Translators1和Translators2两个页面展示如何将Integer、Long、Double及String类型的值从一个页面传递到另一个页面。

页面之间传递值，以前已经讲过，这里不一样的是变量的类型不一样了，具体看源码吧：

Translators1.java

/**

* 项目名称：TapestryStart

* 开发模式：Maven+Tapestry5.x+Tapestry-hibernate+Mysql

* 网址： http://www.flywind.org

* 版本：1.0

package com.tapestry.app.pages;

import org.apache.tapestry5.annotations.InjectPage;

import org.apache.tapestry5.annotations.Property;

public class Translators1 {

@Property

private Integer integerField;

@Property

private Long longField;

@Property

private Double doubleField;

@Property

private String stringField;

// Other pages

@InjectPage

private Translators2 page2;

// The code

Object onSuccess() {

page2.set(integerField, longField, doubleField, stringField);

return page2;

}

Translators1.tml

<html t:type="layout" title="tapestryStart Index" t:sidebarTitle="Framework Version"

xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd" xmlns:p="tapestry:parameter">

<t:errors/>

<table>

<tr>

<td>Integer类型.</td>

</tr>

<tr>

<td>Long类型.</td>

</tr>

<tr>

<td>Double类型.</td>

</tr>

<tr>

<td>String类型.</td>

</tr>

<tr>

</tr>

</table>

</form>

</html>

Translators2.java

/**

package com.tapestry.app.pages;

import org.apache.tapestry5.annotations.Property;

public class Translators2 {

@Property(write = false)

private Integer integerField;

@Property(write = false)

private Long longField;

@Property(write = false)

private Double doubleField;

@Property(write = false)

private String stringField;

public void set(Integer integerField, Long longField, Double doubleField, String stringField) {

this.integerField = integerField;

this.longField = longField;

this.doubleField = doubleField;

this.stringField = stringField;

}

Object[] onPassivate() {

return new Object[] { integerField, longField, doubleField, stringField };

}

void onActivate(Integer integerField, Long longField, Double doubleField, String stringField) {

this.integerField = integerField;

this.longField = longField;

this.doubleField = doubleField;

this.stringField = stringField;

}

Translators2.tml

</table>
