# 创建项目 #

参照 [http://blog.csdn.net/oktfolio/article/details/79451766][http_blog.csdn.net_oktfolio_article_details_79451766]

# sring-boot-starter-web 引入的依赖包 #

![这里写图片描述][70]

# 引入 spring-tool 依赖 #

修改代码，自动编译运行。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>

需要修改 IntelliJ IDEA 的配置。

1.  勾选 Build project automatically  
    ![这里写图片描述][70 1]
2.  Ctrl + Shift + Alt + /
3.  Registry
4.  勾选 compiler.automake.allow.when.app.running  
    ![这里写图片描述][70 2]

# 运行 #

直接运行 main 方法、IntelliJ IDEA 运行，或者使用 maven 命令：spring-boot:run

# Code #

IndexController.java

package me.oktfolio.springboot.demo_2_1.controller;
    
    import me.oktfolio.springboot.demo_2_1.bean.User;
    import org.springframework.web.bind.annotation.PathVariable;

    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.RestController;
    
    import java.time.LocalDateTime;
    import java.util.HashMap;
    import java.util.Map;
    
    @RestController // 包含 @ResponseBody
    @RequestMapping(value = "/index")
    public class IndexController {
    
        @RequestMapping
        public String index() {
            return "hello world";
        }
    
    
        @RequestMapping(value = "/get")
        public Map<String, String> get(@RequestParam String name) {
            Map<String, String> map = new HashMap<>();
            map.put("name", name);
            map.put("value", "hello world");

        @RequestMapping(value = "/find/{id}/{name}")
        public User get(@PathVariable("id") Integer id, @PathVariable(value = "name") String name) {
            User user = new User();
            user.setId(id);
            user.setUserName(name);
            user.setLocalDateTime(LocalDateTime.now());
            return user;
        }
    }

User.java

package me.oktfolio.springboot.demo_2_1.bean;
    
    import java.time.LocalDateTime;
    
    public class User { 
    
        private Integer id;
        private String userName;
    
        private LocalDateTime localDateTime;
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName;
        }
    
        public LocalDateTime getLocalDateTime() {
            return localDateTime;
        }
    
        public void setLocalDateTime(LocalDateTime localDateTime) {
            this.localDateTime = localDateTime;
        }
    }
