依赖：

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.5.1.RELEASE</version>
            <relativePath/> 
        </parent>
    
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>

示例代码：

@RequestMapping(value = "/register", method = RequestMethod.GET)
        @ResponseBody
        public String register(){
    
            return "user register";
        }
    
        /** @GetMapping 是Spring 4.3 的新特性 */
        @GetMapping("getUser")
        @ResponseBody
        public String getUser(){
    
            return "user get";
        }
    
        /** @PostMapping 也是Spring 4.3 的新特性 */
        @PostMapping("createUser")
        @ResponseBody
        public String createUser(){
    
            return "user create";
        }
    
    
        /** * @RequestParam 接收提交的参数，参数默认是必填的 * @RequestParam(value = "password", required = false) required = false，可以不是必填的参数 * */
        @PostMapping("buildUser")
        @ResponseBody
        public String buildUser(@RequestParam("username") String username, 
                                                @RequestParam(value = "password", required = false) String password){
    
            return "提交的参数:username" + username + " password:" + password;
        }

**在SpringBoot中使用JSP**

SpringBoot默认不支持JSP，需要在项目中添加相关的依赖

<dependency>
                <groupId>org.apache.tomcat.embed</groupId>
                <artifactId>tomcat-embed-jasper</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.eclipse.jdt.core.compiler</groupId>
                <artifactId>ecj</artifactId>
                <version>4.6.1</version>
                <scope>provided</scope>
            </dependency>

配置文件增加配置项：

spring.mvc.view.prefix=/WEB-INF/views/
    
    spring.mvc.view.suffix=.jsp

@Controller
    public class LoginController { 
    
        @PostMapping("login")
        public String login(String username, String password){
    
            if (username.equals(password)){
                return "list";
            }
            return "login";
        }
    
        @GetMapping("form")
        public String from(Model model){
    
            model.addAttribute("username", "tomcat");
            return "form";
        }
    
    }
