在Freemarker中迭代地图

Question

  

可能重复：
  Freemarker iterating over hashmap keys

我有一个哈希映射，其中包含项ID作为键，Item对象作为值。以下是伪代码 -

allItems : {
  12: itemObj1 (id:12, name:myitem1)
  13: itemObj2 (id:13, name:myitem2)
  14: itemObj3 (id:14, name:myitem3)
}

在result.ftl上我需要迭代这个map并获取Item Object的值。我尝试过这种方法但无法从Item对象中获取值 -

<#list item?keys as it>
    ${it} = ${item.get(it)[name]}
</#list>

Answer 1

我想你想要：

<#list allItems?keys as it>
  ${it} = ${allItems[it].name} 
</#list>

Answer 2

<#assign seq=["a","b","c"]>
<#list seq as l>
  ${l[1]}
// It will print b
  ${l[0]}
//It will print a
</#list>
