第十八章 springboot + thymeleaf

代码结构：

1、ThymeleafController

 1 package com.xxx.firstboot.web;
 2 
 3 import org.springframework.stereotype.Controller;
 4 import org.springframework.ui.Model;
 5 import org.springframework.web.bind.annotation.RequestMapping;
 6 import org.springframework.web.bind.annotation.RequestMethod;
 7 import org.springframework.web.bind.annotation.RequestParam;
 8 import org.springframework.web.bind.annotation.ResponseBody;
 9 
10 import io.swagger.annotations.Api;
11 import io.swagger.annotations.ApiOperation;
12 
13 @Api("测试Thymeleaf和devtools")
14 @Controller
15 @RequestMapping("/thymeleaf")
16 public class ThymeleafController {
17 
18     @ApiOperation("第一个thymeleaf程序")
19     @RequestMapping(value = "/greeting", method = RequestMethod.GET)
20     public String greeting(@RequestParam(name = "name", required = false, defaultValue = "world") String name,
21                            Model model) {
22         model.addAttribute("xname", name);
23         return "index";
24     }
25 
26     @ApiOperation("thymeleaf ajax")
27     @ResponseBody
28     @RequestMapping(value = "/ajax", method = RequestMethod.GET)
29     public String ajax(@RequestParam("username") String username) {
30         return username;
31     }
32 
33 }

说明：

第一个是springMVC经典返回形式modelAndView
第二个是ajax返回形式

2、index.html

 1 <!DOCTYPE HTML>
 2 <html xmlns:th="http://www.thymeleaf.org">
 3 <head>
 4 <title>index</title>
 5 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
 6 
 7 <link th:href="@{/bootstrap/css/bootstrap.min.css}" rel="stylesheet"/>
 8 <link th:href="@{/bootstrap/css/bootstrap-theme.min.css}" rel="stylesheet" />
 9 </head>
10 <body>
11     <div class="panel panel-primary">
12         <div class="panel-heading">hello</div>
13         <div class="panel-body" th:text="${xname}"></div>
14     </div>
15     <div class="panel panel-warning">
16         <div class="panel-heading">hello</div>
17         <div id="usernamediv" class="panel-body"></div>
18     </div>
19     <script type="text/javascript" th:src="@{/js/jquery-1.11.1.js}"></script>
20     <script type="text/javascript" th:src="@{/bootstrap/js/bootstrap.min.js}"></script>
21     <script th:inline="javascript">
22         $(function(){
23             $.ajax({
24                 url:"/thymeleaf/ajax",
25                 data:{
26                     username:"xxx"
27                 },
28                 type:"get",
29                 dataType:"text",
30                 success:function(text){
31                     alert(text);
32                     $("#usernamediv").text(text);
33                 }
34             });
35         });
36     </script>
37 </body>
38 </html>

说明：

引入外界静态资源的方式@{/xxx}，默认的静态资源的根是"static"
ajax的返回类型dataType要选好（一般就是"text"/"json"）
ajax的请求方法类型type要与controller相同，否则抛出405错误
