How to iterate over map using mustache in java
提问by Simple-Solution
I'm newbie to mustache and was wondering how to iterate over HashMapusing mustache given this Map
我是 mustache 的新手，想知道如何迭代HashMap使用 mustache 给定这个Map
Map mapA = new HashMap();
mapA.put("key1", "element 1");
mapA.put("key2", "element 2");
mapA.put("key3", "element 3");
The map key names vary. Ideally, I want mustache to iterate over both its key and values. So in java it will look like this:
地图键名各不相同。理想情况下，我希望 mustache 迭代其键和值。所以在java中它看起来像这样：
for (Map.Entry<String, Object> entry : mapA.entrySet()) {
String key = entry.getKey();
String value = entry.getValue();
// ...
}
So can someone tell me how to achieve above in mustache. I mean how would the template looks like? I tried this template but had no luck so far :(
那么有人可以告诉我如何在胡子上实现上述目标。我的意思是模板会是什么样子？我试过这个模板，但到目前为止没有运气:(
{{#mapA}}
<li>{{key}}</li>
<li>{{value}}</li>
{{/mapA>
So when I run this template, the output <li>tags comes out empty, why?
Thanks.
所以当我运行这个模板时，输出<li>标签是空的，为什么？谢谢。

I don't know mustachebut basing on some samples of code I have seen, I think you should define an entrySetvariable in your Java code like this
我不知道mustache但根据我看到的一些代码示例，我认为您应该entrySet在 Java 代码中定义一个这样的变量
Set<Map.Entry<String,Object>> entrySet = mapA.entrySet();
and use it instead of mapAin your mustachecode
并mapA在您的胡子代码中使用它而不是
{{#entrySet}}
<li>{{key}}</li>
<li>{{value}}</li>
{{/entrySet}}

As @Dici mentioned above, you can use an entrySet. You do not have to use any special options on the factory and can pass it directly to execute. In your template you can use a top level map if your template is very simple.
正如@Dici 上面提到的，您可以使用entrySet. 您不必在工厂中使用任何特殊选项，可以直接将其传递给execute. 如果您的模板非常简单，您可以在您的模板中使用顶级地图。
Java
爪哇
Map<String, String> map = new HashMap<>();
map.put("key1", "value1");
map.put("key2", "value2");
Writer writer = new OutputStreamWriter(System.out);
MustacheFactory mustacheFactory = new DefaultMustacheFactory();
Mustache template = mustacheFactory.compile("map.template");
template.execute(writer, map.entrySet()).close();
Mustache Template (map.template)
小胡子模板 ( map.template)
{{#.}}
keylabel:{{key}} : valuelabel:{{value}}
{{/.}}
Result
结果
keylabel:key1 : valuelabel:value1
keylabel:key2 : valuelabel:value2
