SpringMVC整合FreeMarker产生模板视图

引入包：

<dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.20</version></dependency>

第一次引入的包groupId为freemarker，版本2.3.8，报错，改为org.freemarker正常。

配置：

order指定的优先级中，freeMarker视图高于InternalResource视图，所以系统使用freeMarker解析视图。

接口：

package com.smart.web;import java.io.UnsupportedEncodingException;import java.util.ArrayList;import java.util.List;import org.springframework.http.HttpEntity;import org.springframework.http.HttpStatus;import org.springframework.http.ResponseEntity;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import com.smart.domain.User;@Controller@RequestMapping("/sp4")public class Sp4Controller {@RequestMapping(value="m1",method=RequestMethod.GET)@ResponseBodypublic String m1(){return "inm1";}@RequestMapping(value = "/m2",method=RequestMethod.POST)public ResponseEntity<User> m2(HttpEntity<User> requestEntity) throws UnsupportedEncodingException {User user = requestEntity.getBody();System.out.println("######:"+user+"---"+user.getRealName());user.setUserId("1000");return new ResponseEntity<User>(user, HttpStatus.OK);}@RequestMapping(value="/m3",method=RequestMethod.GET)public String m3(ModelMap mm){List<User> list = new ArrayList<User>();User user = new User();user.setUserId("1");user.setUserName("zhangsan");list.add(user);User user1 = new User();user1.setUserId("2");user1.setUserName("lisi");list.add(user1);mm.addAttribute("list", list);return "suc";}@RequestMapping(value="/m4" ,method=RequestMethod.GET)public String m4(ModelMap mm){List<User> list = new ArrayList<User>();User user = new User();user.setUserId("1");user.setUserName("zhangsan");list.add(user);User user1 = new User();user1.setUserId("2");user1.setUserName("lisi");list.add(user1);mm.addAttribute("userList", list);return "userFtl";}}

m4方法；

模板，和配置对应，在/WEB-INF/ftl  下创建 userFtl.ftl文件

<#import "spring.ftl" as spring /><html><head><title>smart</title></head><body>用户列表<table>           <#list userList as user><tr><td>   <a href="<@spring.url '/user/showUser/${user.userName}.html'/>">      ${user.userName}   </a></td>        <td>${user.userId}</td>        <td>${user.userId}</td>    </tr>           </#list> <table></body></html>

这里使用spring定义的宏，<@spring.url '/user/showUser/${user.userName}.html'/>产生的路径为相对于项目项目部署路径。
