配置yml文件，整了两天，终于能自动生成数据库表了，记录一下

启动类：

package com.java1234;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class HelloWorldApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(HelloWorldApplication.class, args);
    	}
    
    }

Book实体类

package com.java1234.entity;
    
    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.Table;
    
    @Entity
    @Table(name="t_book")
    public class Book {
    
    	@Id //主键
    	@GeneratedValue  //自增
    	private Integer id;
    	
    	@Column(length=100)
    	private String bookName;
    	
    	@Column(length=100)
    	private String author;
    	public Integer getId() {
    		return id;
    	}
    	public void setId(Integer id) {
    		this.id = id;
    	}
    	public String getBookName() {
    		return bookName;
    	}
    	public void setBookName(String bookName) {
    		this.bookName = bookName;
    	}
    	public String getAuthor() {
    		return author;
    	}
    	public void setAuthor(String author) {
    		this.author = author;
    	}
    	
    	
    }

application.yml

server:
      port: 8080
      servlet.context-path: /
     
    spring:
       datasource:
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://localhost:3306/db_bo?useSSL=false&serverTimezone=GMT
          username: root
          password: '000'
       jpa:
           hibernate:
             ddl-auto: update
           properties:
             hibernate: 
               dialect: org.hibernate.dialect.MySQL5Dialect
           show-sql: true
           open-in-view: false

生成的数据表如下：
