我有一个哈希图,如下所示
HashMap<String, String> map = new HashMap<String, String>();
map.put("one", "1");
map.put("two", "2");
map.put("three", "3");
Map root = new HashMap();
root.put("hello", map);我的Freemarker模板是:
<html><body>
<#list hello?keys as key>
${key} = ${hello[key]}
</#list>
</body></html>这样做的目的是在我生成的HTML中显示键值对。请帮我做这件事。谢谢!

代码:
HashMap<String, String> test1 = new HashMap<String, String>();
Map root = new HashMap();
test1.put("one", "1");
test1.put("two", "2");
test1.put("three", "3");
root.put("hello", test1);
Configuration cfg = new Configuration(); // Create configuration
Template template = cfg.getTemplate("test.ftl"); // Filename of your template
StringWriter sw = new StringWriter(); // So you can use the output as String
template.process(root, sw); // process the template to output
System.out.println(sw); // eg. output your result模板:
<body>
<#list hello?keys as key>
${key} = ${hello[key]}
</#list>
</body>输出:
<body>
two = 2
one = 1
three = 3

从2.3.25开始,您可以这样做:
<body>
<#list hello as key, value>
${key} = ${value}
</#list>

使用保持键-值对插入顺序的映射: LinkedHashMap
