英文:
Migrating Spring Boot (3.0.5) with Spring Batch(5.0): Spring Batch specific "Auto Table creation" is not working
问题
老版本：
Java: 11
Spring Boot: 2.5.2
迁移后（新版本）：
Java: 17
Spring Boot: 3.0.5
Spring Batch: 5.0
问题：
与Spring Batch相关的元数据（自动创建表）不再起作用（在升级前，在bootstrap.yml中定义了“spring.jdbc.initialize-schema: always”，之前运行良好）。
spring.datasource.url，spring.datasource.username，spring.datasource.password和spring.datasource.schema都按原样定义（升级前运行良好）。
只是为了尝试：已为Spring Boot定义了以下内容以读取主数据源（这是Spring Batch特定的，不是应用程序特定的），但没有成功。
@Configuration
public class DBConfig {
@Primary
@Bean(name = "dataSource")
public DataSource dataSource() {
DataSource dataSource = DataSourceBuilder.create().username("XXX")
.password("XXX$").url("jdbc:oracle:thin:@host:port/XXX").build();
return dataSource;
}
}
英文:
Old versions:
Java: 11
Spring Boot : 2.5.2
After Migration : (new versions)
Java:17
Spring Boot: 3.0.5
Spring Batch 5.0
Problem:
Spring batch related meta data (Auto table creation) is not working any more. (having “spring.jdbc.initialize-schema: always” defined in bootstrap.yml,and was working fine before upgrade)
spring.datasource.url, spring.datasource.username, spring.datasource.password and spring.datasource.schema are all defined as it is (working before).
Just to try out: have defined below for Spring Boot to read the primary data source (which is spring Batch specific and not application specific) but no luck.
@Configuration`
public class DBConfig {
@Primary
@Bean(name = "dataSource")
public DataSource dataSource() {
DataSource dataSource = DataSourceBuilder.create().username("XXX")
.password("XXX$").url("jdbc:oracle:thin:@host:port/XXX").build();
return dataSource;
}
}

I guess you are using @EnableBatchProcessing. If this is the case, that is the reason why tables are not created, see https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#enablebatchprocessing-is-now-discouraged.
如果您正在使用@EnableBatchProcessing，那么这就是表格未被创建的原因，请参阅 https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#enablebatchprocessing-is-now-discouraged.
If you want to use @EnableBatchProcessing, then you need to initialize the database yourself, see example in https://stackoverflow.com/questions/75619930/spring-batch-5-and-spring-boot-3-meta-data-tables-not-created-when-using-program
如果您想使用@EnableBatchProcessing，那么您需要自行初始化数据库，请参考 https://stackoverflow.com/questions/75619930/spring-batch-5-and-spring-boot-3-meta-data-tables-not-created-when-using-program
