在 Spring Boot 中的辅助数据库上创建表
Posted
技术标签:
【中文标题】在 Spring Boot 中的辅助数据库上创建表【英文标题】：Create table on secondary db in spring boot 【发布时间】：2018-12-24 07:45:00 【问题描述】：我在 spring boot 中有两个 dbs 可以使用。连接已经建立，但是 db2 的 schema.sql 在初始化时失败，并且正在为 db1 而不是 db2 执行。下面是我项目中的 application.properties。 我按照这个例子https://medium.com/@joeclever/using-multiple-datasources-with-spring-boot-and-spring-data-6430b00c02e7
有人可以帮我解决这个问题吗？
spring.datasource.url=jdbc:mysql://host:port/db
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
h2.datasource.url=jdbc:h2:mem:testdb
h2.datasource.username=sa
h2.datasource.password=
h2.datasource.driver-class-name=org.h2.Driver
h2.datasource.data=schema-h2.sql
spring.jpa.generate-ddl=true
h2.datasource.initialize=true
h2.datasource.platform=h2
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
以下是数据库的配置文件：
MySqlDbConfig.java
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactory",
basePackages = "com.repository.mysql")
public class MySqlDbConfig
@Primary
@Bean(name = "dataSource")
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource()
return DataSourceBuilder.create().build();
@Primary
@Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
EntityManagerFactoryBuilder builder, @Qualifier("dataSource") DataSource dataSource)
return builder.dataSource(dataSource).packages("com.domain.mysql").persistenceUnit("mqsql")
.build();
@Primary
@Bean(name = "transactionManager")
public PlatformTransactionManager transactionManager(
@Qualifier("entityManagerFactory") EntityManagerFactory entityManagerFactory)
return new JpaTransactionManager(entityManagerFactory);
H2DbConfig.java
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "h2EntityManagerFactory",
transactionManagerRef = "h2TransactionManager",
basePackages = "com.repository.h2")
public class H2DbConfig
@Bean(name = "h2DataSource")
@ConfigurationProperties(prefix = "h2.datasource")
public DataSource h2DataSource()
return DataSourceBuilder.create().build();
@Bean(name = "h2EntityManagerFactory")
public LocalContainerEntityManagerFactoryBean h2EntityManagerFactory(
EntityManagerFactoryBuilder builder, @Qualifier("h2DataSource") DataSource dataSource)
return builder.dataSource(dataSource).packages("com.domain.h2").persistenceUnit("h2")
.build();
@Bean(name = "h2TransactionManager")
public PlatformTransactionManager h2TransactionManager(
@Qualifier("h2EntityManagerFactory") EntityManagerFactory h2EntityManagerFactory)
return new JpaTransactionManager(h2EntityManagerFactory);
下面是堆栈跟踪

【问题讨论】：
您能否提供您的源代码或任何其他详细信息或例外情况 Here 你去看看。请分享您的 bean 声明代码和详细的堆栈跟踪。 @xXxpRoGrAmmErxXx ，添加源代码和错误堆栈跟踪@ vahdet 添加源代码和错误堆栈跟踪 @vahdet 提供的示例仅显示了如何连接到数据库，这已经对我有用。我试图在初始化期间在 db2（在本例中为 h2）中创建一个表，但失败了 【参考方案1】：我解决了这个问题。将 @primary 注释移动到 h2config 并删除了额外的应用程序属性。按预期工作。
