Springboot服务实现执行SQL脚本文件

作者：一棵星

这篇文章主要介绍了Springboot服务实现执行SQL脚本文件方式,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教

Springboot服务执行SQL脚本文件

当sql脚本文件包含不同数据库实例sql时，遍历读取sql文件再插入时，由于是不同的数据库实例这种方式就不行了，这时就需要程序直接执行sql脚本。

Java程序执行sql文件时注意：

springboot执行sql脚本

/**
 * 执行sql脚本
 * @throws SQLException
 */
private void executeSqlScript(String path) throws IOException {
    ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
    resourceDatabasePopulator.addScript(new ClassPathResource(path));
    // resourceDatabasePopulator.addScript(new FileSystemResource(path));
    resourceDatabasePopulator.execute(dataSource);
}

注意：文件需要在class path下

本文将文件放入到 src/main/resources/目录下，如下图：

当服务运行时，时正常时报错，报错信息如下：Caused by: java.io.FileNotFoundException.

详细报错信息如下：

如何解决上述报错呢？

不使用classpath相对路径

resourceDatabasePopulator.addScript(new ClassPathResource(path))

使用文件系统的绝对路径：

resourceDatabasePopulator.addScript(new FileSystemResource(path))

如下所示：

/**
 * 执行sql脚本
 * @throws SQLException
 */
private void executeSqlScript(String path) throws IOException {
    ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
    // resourceDatabasePopulator.addScript(new ClassPathResource(path));
    resourceDatabasePopulator.addScript(new FileSystemResource(path));
    resourceDatabasePopulator.execute(dataSource);
}

注意：这个path是系统的绝对路径

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
