Spring Batch-如何在不同的架构上创建元数据表? [英] Spring Batch - How to create metadata tables on Different schema?
本文介绍了Spring Batch-如何在不同的架构上创建元数据表?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我希望在同一MySQL主机上创建Spring Batch Metadata table，但使用不同的架构.
我想在 Test 架构上创建特定于应用程序的表，并在 batchmetadata 架构上创建元数据表.
I am looking to create the Spring Batch Metadata table on the same MySQL Host, but using different schema.
I want to create application specific tables on Test schema and Metadata tables on batchmetadata schema.

推荐答案
感谢Sushil提供指导.我可以通过以下链接解决此问题:多个数据源和在Spring Boot中创建模式.
Thanks Sushil for guidance. I was able to solve the issue by following link: Multiple data source and schema creation in Spring Boot.
spring.jpa.hibernate.ddl-auto=create已停止工作，不是因为您有两个DataSources，而是因为您的应用程序正在创建自己的LocalContainerEntityManagerFactoryBeans.这样会禁用LocalContainerEntityManagerFactoryBean的自动配置，因此您现在必须自己进行配置.
spring.jpa.hibernate.ddl-auto=create has stopped working, not because you have two DataSources, but because your application's creating its own LocalContainerEntityManagerFactoryBeans. This has the effect of disabling the auto-configuration of a LocalContainerEntityManagerFactoryBean so you now have to configure it yourself.
test模式-希望用于特定于应用程序的用途.
test schema - Want to used for application specific usage.
batchmetadata模式-想要用于Spring Batch元数据表
batchmetadata schema - Want to used for Spring Batch Metadata tables
因此，只需在@PrimaryDS和@SecondaryDS.
@Bean(name = "primaryEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory( EntityManagerFactoryBuilder builder) {
Map<String, Object> properties = new HashMap<String, Object>();
properties.put("hibernate.hbm2ddl.auto", "update");
return builder
.dataSource(getSeconadaryBatchDataSource())
.packages("com.example.model")
.persistenceUnit("default")
.properties(properties)
.build();
}
