1、pom依赖

<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-thymeleaf</artifactId>
    		</dependency>
    		
    		<dependency>
              <groupId>net.sourceforge.nekohtml</groupId>
              <artifactId>nekohtml</artifactId>
              <version>1.9.15</version>
           </dependency>

2、application配置

thymeleaf:
          cache: false  #关闭缓存
          prefix: classpath:/template/
          suffix: .html
    #      mode: LEGACYHTML5
          encoding: UTF-8
          content-type: text/html
          #thymeleaf end

3、在resources下面新建template目录

4、新建login.html

<!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8"/>
    <title>hello world</title>
    </head>
    <body>
    <form class="form-signin" role="form" th:action="@{/user/login}" th:method="post">
       <input type="text" class="form-control" placeholder="用户名" required="required" name="userName" />
       <input type="password" class="form-control" placeholder="密码" required="required" name="password" />
       <button class="btn btn-lg btn-warning btn-block" type="submit">登录</button>
     </form>
    </body>
    </html>

5、controller代码

import javax.servlet.http.HttpServletResponse;
    
    import org.apache.logging.log4j.LogManager;
    import org.apache.logging.log4j.Logger;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    import cn.sunline.edsp.tsp.portal.constant.Const;
    import cn.sunline.edsp.tsp.portal.entity.User;
    
    @Controller
    public class PortalController {
    	
    	//用户名
    	private final static String USERNAME = Const.USERNAME.toString();
    	//密码
    	private final static String PASSWORD = Const.PASSWORD.toString();
    	
    	private final Logger logger = LogManager.getLogger(PortalController.class);
    
    	/**
    	 * 登录界面
    	 * @param response
    	 * @return
    	 */
    	@RequestMapping(value = "login")
    	public String login(HttpServletResponse response) {
    		return "login";
    	}
    	
    	/**
    	 * 登录处理
    	 * @return
    	 */
    	@RequestMapping(value = "/user/login",method= RequestMethod.POST)
    	public String toLogin(User user) {
    		
    		if(!USERNAME.equals(user.getUserName())) {
    			logger.error("用户名错误");
    			return "login";
    		}
    		if(!PASSWORD.equals(user.getPassword())) {
    			logger.error("密码错误");
    			return "login";
    		}
    		return "redirect:/user/index";
    	}
    	@RequestMapping(value = "/user/index")
    	public String toIndex() {
    		return "index";
    	}
    }
