Spring Boot 2 系列如何正確地初始化data.sql和schema.sql腳本

Spring Boot 2.0 遷移手冊

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide

 

Spring Boot 2 初始化數據庫腳本 data.sql & schema.sql 必須提供三組同樣的用戶名稱和用戶密碼

這在官網和互聯網上目前沒人提及

application.yml正確的配置格式如下：

spring:
  profiles: development 
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/dev?useSSL=false
    username: root
    password: dbpass
    schema-username: root
    schema-password: dbpass
    data-username: root
    data-password: dbpass
    platform: mysql
    schema: classpath:schema.sql
    data: classpath:data.sql
    continue-on-error: true
    initialization-mode: always

再舉一範例

創建的表結構由jpa定義的對象實體映射生成，只定義表數據初始化文件data.sql：

application.yml

#security:
#  oauth2:
#    client:
#      client-id: bd1c0a783ccdd1c9b9e4
#      client-secret: 1a9030fbca47a5b2c28e92f19050bb77824b5ad1
#      access-token-uri: https://github.com/login/oauth/access_token
#      user-authorization-uri: https://github.com/login/oauth/authorize
#      client-authentication-scheme: form
#    resource:
#      user-info-uri: https://api.github.com/user
#      prefer-token-info: false
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/db1?useSSL=false
    username: root
    password: 123456
    data-username: root
    data-password: 123456
    initialization-mode: always
  jpa:
    hibernate:
      ddl-auto: create

data.sql

INSERT INTO employee(id,name,birth,address)VALUES(1823,'Jack Chen','1993-05-29','Beijing');
INSERT INTO employee(id,name,birth,address)VALUES(1202,'Tim He','1986-12-26','Shanghai');
INSERT INTO employee(id,name,birth,address)VALUES(1304,'John Hu','1980-01-08','Shanxi');

Employee.java 

package com.contoso.employee;

import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Employee {
	
	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private Long id;
	private String name;
	private Date birth;
	private String address;

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Date getBirth() {
		
		return birth;
	}

	public void setBirth(Date birth) {
		this.birth = birth;
	}

	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}

}

EmployeeRepository.java     允許有同名同姓的僱員

package com.contoso.employee;

import java.util.List;

import org.springframework.data.repository.PagingAndSortingRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;

@RepositoryRestResource(collectionResourceRel = "employee", path = "employee")
public interface EmployeeRepository extends PagingAndSortingRepository<Employee, Long> {
	List<Employee> findEmployeeByName(@Param("name") String name);
}
