Freemarker常用指令使用示例

package www.asuan.com.controller;

import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloWorldController {
@RequestMapping("/helloWorld")
public String helloWorld(Model model) {
// 示例一
int flag = 0;
model.addAttribute("flag", flag);
// 示例二
List<String> noExistList = new ArrayList<String>();
noExistList = null;
model.addAttribute("noExistList", noExistList);
// 示例三
List<String> strList = new ArrayList<String>();
strList.add("www.");
strList.add("cnblogs.");
strList.add("com/sunang");
model.addAttribute("strList", strList);
// 示例四
Map<String, String> strMap = new HashMap<String, String>();
strMap.put("mapKey0", "www.");
strMap.put("mapKey1", "cnblogs.");
strMap.put("mapKey2", "com/sunang");
model.addAttribute("strMap", strMap);
// 示例五
Date nowTime = new Date();
model.addAttribute("nowTime", nowTime);//传输时间对象
return "helloWorld.ftl";
}
}

step2.编写ftl文件，代码如下：
