src/main/java 下
controller层，路由功能
dao层，数据库的访问
domain，bean的存放
service，业务层
application.java，spring boot的主启动程序
src/main/resources/application.properties ，spring boot的配置文件

简易说明：
thymeleaf -- 用来渲染模板，spring boot 不建议使用JSP
devtools -- 用来热部署，可以只关注coding，保存后自行restart
jpa -- 数据库访问，很好很强大
LoginApplication.java
package com.jwen.login; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class LoginApplication { public static void main(String[] args) { SpringApplication.run(LoginApplication.class, args); } }
UserController.java
package com.jwen.login.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import com.jwen.login.domain.User; import com.jwen.login.service.UserService; @Controller @EnableAutoConfiguration public class UserController { @Autowired private UserService userService; @RequestMapping("/") @ResponseBody String welcome() { return "welcome my first spring boot project"; } @RequestMapping("/notVerify") @ResponseBody String notVerify() { return "username or password NOT correct"; } @RequestMapping("/login") String login(Model model) { model.addAttribute("user", new User()); return "login"; } @RequestMapping("/register") String register(Model model) { model.addAttribute("user", new User()); return "register"; } @RequestMapping(value = "/registerUser", method = RequestMethod.POST) @ResponseBody String registerUser(User user, Model model) { return userService.registerUser(user); } @RequestMapping(value = "/userLogin", method = RequestMethod.POST) String userLogin(User user, Model model) { boolean verify = userService.verifyUser(user); if (verify) { model.addAttribute("name", user.getName()); model.addAttribute("password", user.getPassword()); return "result"; } else { return "redirect:/notVerify"; } } }
@RequestMapping("/login") ensures that HTTP requests to/loginare mapped to thelogin()method，这个注解可以使指定的uri指向到该方法
@ResponseBody 返回response，一般return为string的话，页面就直接返回该string
配置application.properties，指向html文件：
spring.thymeleaf.prefix=classpath:/templates/ spring.thymeleaf.cache=false spring.thymeleaf.mode=HTML5 spring.thymeleaf.encoding=UTF-8 spring.thymeleaf.content-type=text/html
会去识别resources/templates下的html文件，根据return回来的string来匹配
@RequestMapping("/login")
String login(Model model) {
model.addAttribute("user", new User());
return "login";
}
这里没有@ResponseBody ，因此会去匹配到login.html
待续
