springboot学习笔记

 thymeleaf使用：th:type　　type为我们需要展示的信息的类型可以为text

<h3  th:each= "user:${user}"  th:text="${user}"></h3> 遍历并且输出为text 前一个user为

mode.addAttribute("user", Arrays.asList("guosai","lifei","huanglun")); 中的user 

后一个user为遍历出来的每一个user

@Controller
public class HelloController {

    @GetMapping(value = "hello")
    public String index( Model mode){
        //mode.addAttribute("msg","hello,springboot");
        mode.addAttribute("user", Arrays.asList("guosai","lifei","huanglun"));
        return "test";//返回值就是最后跳转的页面
    }
}
