如何在thymeleaf中过滤集合:每个都使用另一个属性进行比较 [英] How to filter a collection in thymeleaf th:each using another property in comparison

问题描述

我正在尝试按照以下网址中的示例使用Thymeleaf过滤集合. 对投影进行投影和选择"部分. http://doanduyhai.wordpress. com/2012/04/14/spring-mvc-part-iv-thymeleaf-advanced-usage/

<tr th:each="artist,rowStat : ${listArtits.?[alive == true]}">
...
</tr>

但是，我想使用另一个属性而不是固定值(true/false).例如

<tr th:each="artist,rowStat : ${listArtits.?[played > playedCountReq]}">
...
</tr>

其中，playedCountReq是Thymeleaf可用的另一个表单变量.我收到以下错误.在类型...的对象上找不到属性或字段"playedCountReq"

我尝试了多种方法，但没有成功.有什么建议吗?

解决方案

我成功了:)这是解决方法:

在控制器中:

(...)
Person p1 = new Person();
p1.setAge(20);
Person p2 = new Person();
p2.setAge(30);
List<Person> list = Lists.newArrayList(p1,p2);
modelMap.addAttribute("list", list);
Integer minAge = 13;
modelMap.addAttribute("minAge", minAge);
(...)

在html中:

<table th:with="min=${minAge}">
<tr th:each="person,rowStat : ${list.?[age > __${min}__]}">
<td><span th:text="${person.age}"></span></td>
</tr>
</table>

输出:

30

希望获得帮助

I am trying to filter the collection using Thymeleaf by following the example in the following url. "Projection & selection on collection" section. http://doanduyhai.wordpress.com/2012/04/14/spring-mvc-part-iv-thymeleaf-advanced-usage/

<tr th:each="artist,rowStat : ${listArtits.?[alive == true]}">
...
</tr>

However I would like to use another property instead of fixed value (true/false). For example

<tr th:each="artist,rowStat : ${listArtits.?[played > playedCountReq]}">
...
</tr>

where as playedCountReq is another form variable available to Thymeleaf. I get the following error. Property or field 'playedCountReq' cannot be found on object of type ...

I tried multiple ways but no success. Any suggestions?

解决方案

I succeded :) Here is solution:

in controller:

(...)
Person p1 = new Person();
p1.setAge(20);
Person p2 = new Person();
p2.setAge(30);
List<Person> list = Lists.newArrayList(p1,p2);
modelMap.addAttribute("list", list);
Integer minAge = 13;
modelMap.addAttribute("minAge", minAge);
(...)

in html:

<table th:with="min=${minAge}">
<tr th:each="person,rowStat : ${list.?[age > __${min}__]}">
<td><span th:text="${person.age}"></span></td>
</tr>
</table>

Output:

30
