Dam*_*men 20 html java freemarker
我有一个哈希映射如下
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>
目标是在我生成的HTML中显示键值对.请帮我做.谢谢!

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
</body>

从2.3.25开始,你可以这样做:
<body>
<#list hello as key, value>
${key} = ${value}
</#list>
</body>
2.3.25之前，如果key包含对象，可以尝试使用
<#assign key_list = map?keys/>
<#assign value_list = map?values/>
<#list key_list as key>
...
<#assign seq_index = key_list?seq_index_of(key) />
<#assign key_value = value_list[seq_index]/>
...
//Use the ${key_value}
...
</#list>
