1.2 application.properties
#主配置文件，配置了这个会优先读取里面的属性覆盖主配置文件的属性
spring.profiles.active=dev
server.port=8888
logging.config=classpath:log4j2-dev.xml
1.3 编写控制器
package com.shyroke.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping(value = “/index”)
public class IndexController {
@RequestMapping(value </span>= "/login"<span style="color: #000000">)
</span><span style="color: #0000ff">public</span><span style="color: #000000"> ModelAndView index(ModelAndView modelAndView) {
modelAndView.setViewName(</span>"index"<span style="color: #000000">);
List</span><String> userList=<span style="color: #0000ff">new</span> ArrayList<String><span style="color: #000000">();
userList.add(</span>"admin"<span style="color: #000000">);
userList.add(</span>"user1"<span style="color: #000000">);
userList.add(</span>"user2"<span style="color: #000000">);
modelAndView.addObject(</span>"userList"<span style="color: #000000">, userList);
</span><span style="color: #0000ff">return</span><span style="color: #000000"> modelAndView;
}
}
1.5 编写index.ftl
<!DOCTYPE html> <html> <head lang="en"> <title>Spring Boot Demo - FreeMarker</title> <link href="/css/index.css" rel="stylesheet"> <script type="text/javascript" src="/jars/jquery-3.2.1.min.js"></script> <script type="text/javascript" src="/js/index.js"></script> </head> <body> <h2>首页<h2><span style="color: #0000ff"><</span><span style="color: #800000">font</span><span style="color: #0000ff">></span> <span style="color: #0000ff"><</span><span style="color: #800000">#list </span><span style="color: #ff0000">userList as item</span><span style="color: #0000ff">></span><span style="color: #000000"> ${item!}</span><span style="color: #0000ff"><</span><span style="color: #800000">br </span><span style="color: #0000ff">/></span> <span style="color: #0000ff"></</span><span style="color: #800000">#list</span><span style="color: #0000ff">></span> <span style="color: #0000ff"></</span><span style="color: #800000">font</span><span style="color: #0000ff">></span> <span style="color: #0000ff"><</span><span style="color: #800000">button </span><span style="color: #ff0000">class</span><span style="color: #0000ff">="a"</span><span style="color: #0000ff">></span> click me<span style="color: #0000ff"></</span><span style="color: #800000">button</span><span style="color: #0000ff">></span>
</body>
</html>
1.6 index.js
$(function() { $('.a').click(function() { alert('hello world'); }); })
1.7 index.css
h2{color:red}
1.8 目录结构
