        org.springframework.boot
               
       
        spring-boot-starter-parent

　　　　　　　　<groupId>org.springframework.boot</groupId>

　　　　　　　　<artifactId>spring-boot-starter-thymeleaf</artifactId>

　　　　　　</dependency>


                 
      
       mysql
                  
      
       mysql-connector-java

         spring-boot-maven-plugin

二、properties配置文件

spring.datasource.url = jdbc:mysql://127.0.0.1:3306/design?characterEncoding=UTF-8&useSSL=falsespring.datasource.username = rootspring.datasource.password = rootspring.datasource.driver-class-name = com.mysql.jdbc.Driver#建表策略，这里用update，即根据实体更新表结构spring.jpa.hibernate.ddl-auto = update

#thymeleaf模板

spring.thymeleaf.prefix=classpath:/templates/

spring.thymeleaf.suffix=.html

spring.thymeleaf.encoding=UTF-8

spring.thymeleaf.content-type=text/html

spring.thymeleaf.mode=HTML5

spring.thymeleaf.cache=false

三、实体类

package com.ltchu.design.model;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.Table;import org.hibernate.annotations.GenericGenerator;@Entity@Table(name="person")public class Person {    @Id    //本来jpa是不支持uuid的，但借用hibernate的方法可以实现。    @GeneratedValue(generator = "uuid")    @GenericGenerator(name = "uuid", strategy = "org.hibernate.id.UUIDHexGenerator")    private String id;        private String name; 　　 　　 public Person(String id, String name) {        super();        this.id = id;        this.name = name;    } 　　...　　setter / getter方法 }

四、Repository

package com.ltchu.design.repository;import org.springframework.data.repository.CrudRepository;import com.ltchu.design.model.Person;public interface PersonRepository extends CrudRepository
     
       {}

五、TestController

package com.ltchu.design.controller;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.ltchu.design.model.Person;import com.ltchu.design.repository.PersonRepository;@Controllerpublic class TestController {    @Autowired    private PersonRepository personRepository;        @RequestMapping(value = {
   "/", "/home"}) 　　 @ResponseBody    public String home() {        personRepository.save(new Person("zhangsan"));        return "home";    }    }

六、DesignApplication

package com.ltchu.design;import java.util.TimeZone;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class DesignApplication {    public static void main(String[] args) {        TimeZone.setDefault(TimeZone.getTimeZone("Asia/Shanghai"));        SpringApplication.run(DesignApplication.class, args);    }}
