java - Flyway如何在SQL文件内插入查询中使用占位符

Question

应用程序属性

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); 

当我使用具有默认扩展名的文件时，上述内容有效，但当我将文件创建为 .sql 扩展名时，出现以下错误。

错误

org.flywaydb.core.api.FlywayException: No value provided for placeholder expressions: ${ESCALATION_QUALIFICATION}.  Check your configuration!
    at org.flywaydb.core.internal.util.PlaceholderReplacer.checkForUnmatchedPlaceholderExpression(PlaceholderReplacer.java:101)
    at org.flywaydb.core.internal.util.PlaceholderReplacer.replacePlaceholders(PlaceholderReplacer.java:78)
    at org.flywaydb.core.internal.dbsupport.SqlScript.<init>(SqlScript.java:79)....

Answer 1

来自网络，建议使用

flyway.placeholderReplacement=false

只有升级到 > Flyway 4.0.3 后才有效(Spring Boot 最新使用 ooold 版本)

另一件事是使用虚假的占位符前缀，这成功了......

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