我有一个哈希图如下
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>
解决方法
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>
