SpringBoot启动自动执行sql脚本

navicat导出sql脚本

SpringBoot启动自动执行sql脚本逻辑编写

大致逻辑：配置文件配置数据库连接；编写建表及新增记录sql脚本，编写@Configuration类读取并执行sql脚本；
 
项目总览图如下

• 编写sql脚本，置于resources/sql目录下

schema.sql

DROP TABLE IF EXISTS people;

CREATE TABLE IF NOT EXISTS people(
    persion_id INT NOT NULL,
    first_name VARCHAR(20),
    last_name VARCHAR(20),
    PRIMARY KEY (persion_id)
);

data.sql

INSERT INTO people VALUES (1, 'ashe', '弗雷尔卓德');
INSERT INTO people VALUES (2, 'annie', '班德尔城');
INSERT INTO people VALUES (3, 'akali', '均衡教派');

• 配置数据库连接

spring.datasource.driver-class-name=org.sqlite.JDBC
spring.datasource.url=jdbc:sqlite:C:/Users/catface/Desktop/auto.db

• 编写@Configuration配置类

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.Resource;
import org.springframework.jdbc.datasource.init.DataSourceInitializer;
import org.springframework.jdbc.datasource.init.DatabasePopulator;
import org.springframework.jdbc.datasource.init.ResourceDatabasePopulator;

import javax.sql.DataSource;

@Configuration
public class CustomizeDataSourceInitializer {

    @Value("classpath:sql/schema.sql")
    private Resource sqlScriptSchema;
    @Value("classpath:sql/data.sql")
    private Resource sqlScriptData;

    @Bean
    public DataSourceInitializer dataSourceInitializer(final DataSource dataSource) {
        DataSourceInitializer dataSourceInitializer = new DataSourceInitializer();
        dataSourceInitializer.setDataSource(dataSource);
        dataSourceInitializer.setDatabasePopulator(databasePopulator());
        return dataSourceInitializer;
    }

    private DatabasePopulator databasePopulator() {
        ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
        resourceDatabasePopulator.addScript(sqlScriptSchema);
        resourceDatabasePopulator.addScript(sqlScriptData);
        resourceDatabasePopulator.setSeparator(";");//分隔符[默认;]
        return resourceDatabasePopulator;
    }
}

• 项目运行后会立即执行sql脚本以测试
