Question

Application.properties

TM_ESCALATION_QUALIFICATION=SHIFT_LEADER

Application.java

@Value( "${TM_ESCALATION_QUALIFICATION}" )
String escalationQualification;

@Bean
InitializingBean printConfigurations(DataSource datasource) {
    return () -> {
            Flyway flyway = new Flyway();
            flyway.setDataSource(datasource);
            flyway.getPlaceholders().put( "ESCALATION_QUALIFICATION", escalationQualification );    
            flyway.migrate();
    };
}

SQL文件

insert into tm_qualification (ID, NAME, DELETABLE) values (sys_guid(), ${ESCALATION_QUALIFICATION}, 0);

当我使用带有默认扩展名的文件时，上面工作正常，但当我将文件设为 .sql 扩展名时，会出现以下错误。

错误

org.flywaydb.core.api.FlywayException: No value provided for placeholder expressions: ${ESCALATION_QUALIFICATION}.  Check your configuration!

从网上建议使用

flyway.placeholderReplacement =假

仅在升级到＆gt;后才能使用flyway 4.0.3（spring boot最新使用ooold版本）

另一件有用的事情就是使用伪造的占位符前缀，这就是诀窍......

flyway.placeholderPrefix = $$$ - bogus - $$$

flyway如何在SQL文件中插入查询中使用占位符
