无法加载驱动程序类org.mariadb.jdbc.Driver
我想在Spring Boot中配置2个JNDI数据源。我尝试了以下配置：
spring.production-datasource.jndi-name=java:/global/production_gatewayspring.production-datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MariaDBDialect
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.warehouse-datasource.jndi-name=java:/global/production_warehouse
spring.warehouse-datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MariaDBDialect
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
主要数据源配置：
@Configuration@EnableJpaRepositories(
basePackages = "org.datalis.plugin.production.entity",
entityManagerFactoryRef = "productionEntityManager",
transactionManagerRef = "productionTransactionManager"
)
@EnableTransactionManagement
public class ContextProductionDatasource {
@Autowired
private Environment env;
@Primary
@Bean(name = "productionDataSourceProperties")
@ConfigurationProperties(prefix="spring.production.datasource")
public DataSourceProperties productionDataSourceProperties() {
return new DataSourceProperties();
}
@Primary
@Bean(name = "productionDataSource")
@ConfigurationProperties(prefix="spring.production.datasource")
public DataSource productionDataSource() {
return DataSourceBuilder.create().build();
}
@Primary
@Bean(name = "productionEntityManager")
public EntityManager productionEntityManager(EntityManagerFactory emf) {
return emf.createEntityManager();
}
@Primary
@Bean(name = "productionTransactionManager")
public PlatformTransactionManager productionTransactionManager(final EntityManagerFactory emf) {
final JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
@Primary
@Bean(name = "productionExceptionTranslation")
public PersistenceExceptionTranslationPostProcessor productionExceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
第二个数据源配置：
@Configuration@EnableJpaRepositories(
basePackages = "org.datalis.plugin.warehouse.entity",
entityManagerFactoryRef = "warehouseEntityManager",
transactionManagerRef = "warehouseTransactionManager"
)
@EnableTransactionManagement
public class ContextWarehouseDatasource {
@Autowired
private Environment env;
@Bean(name = "warehouseDataSourceProperties")
@ConfigurationProperties(prefix="spring.warehouse.datasource")
public DataSourceProperties warehouseDataSourceProperties() {
return new DataSourceProperties();
}
@Bean(name = "warehouseDataSource")
@ConfigurationProperties(prefix="spring.warehouse.datasource")
public DataSource warehouseDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "warehouseEntityManager")
public EntityManager warehouseEntityManager(EntityManagerFactory emf) {
return emf.createEntityManager();
}
@Bean(name = "warehouseTransactionManager")
public PlatformTransactionManager warehouseTransactionManager(final EntityManagerFactory emf) {
final JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
@Bean(name = "warehouseExceptionTranslation")
public PersistenceExceptionTranslationPostProcessor warehouseExceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
但是在部署过程中出现错误：

我正在将Spring boot war与部署的mariadb-java-
client-2.4.2.jar一起部署到Wildfly服务器中。当我使用单个数据源配置时，它工作正常。但是有了第二个数据源，我得到了例外。
您知道如何解决此问题吗？
：
spring.production.datasource.jndi-name=java:/global/production_gatewayspring.production.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.production.jpa.properties.hibernate.dialect=org.hibernate.dialect.MariaDBDialect
spring.production.jpa.show-sql = true
spring.production.jpa.hibernate.ddl-auto = update
spring.warehouse.datasource.jndi-name=java:/global/production_warehouse
spring.warehouse.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.warehouse.jpa.properties.hibernate.dialect=org.hibernate.dialect.MariaDBDialect
spring.warehouse.jpa.show-sql = true
spring.warehouse.jpa.hibernate.ddl-auto = update
第一个数据源：
@Configuration@EnableJpaRepositories(
basePackages = "org.datalis.plugin.production.entity",
entityManagerFactoryRef = "productionEntityManager",
transactionManagerRef = "productionTransactionManager"
)
@EnableTransactionManagement
public class ContextProductionDatasource {
@Primary
@Bean(name = "productionDataSourceProperties")
@ConfigurationProperties(prefix="spring.production")
public DataSourceProperties productionDataSourceProperties() {
return new DataSourceProperties();
}
@Primary
@Bean(name = "productionDataSource")
@ConfigurationProperties(prefix="spring.production")
public DataSource productionDataSource() {
return DataSourceBuilder.create().build();
}
@Primary
@Bean(name = "productionEntityManager")
public EntityManager productionEntityManager(EntityManagerFactory emf) {
return emf.createEntityManager();
}
@Primary
@Bean(name = "productionTransactionManager")
public PlatformTransactionManager productionTransactionManager(final EntityManagerFactory emf) {
final JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
@Primary
@Bean(name = "productionExceptionTranslation")
public PersistenceExceptionTranslationPostProcessor productionExceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
第二个数据源：
@Configuration@EnableJpaRepositories(
basePackages = "org.datalis.plugin.warehouse.entity",
entityManagerFactoryRef = "warehouseEntityManager",
transactionManagerRef = "warehouseTransactionManager"
)
@EnableTransactionManagement
public class ContextWarehouseDatasource {
@Bean(name = "warehouseDataSourceProperties")
@ConfigurationProperties(prefix="spring.warehouse")
public DataSourceProperties warehouseDataSourceProperties() {
return new DataSourceProperties();
}
@Bean(name = "warehouseDataSource")
@ConfigurationProperties(prefix="spring.warehouse")
public DataSource warehouseDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "warehouseEntityManager")
public EntityManager warehouseEntityManager(EntityManagerFactory emf) {
return emf.createEntityManager();
}
@Bean(name = "warehouseTransactionManager")
public PlatformTransactionManager warehouseTransactionManager(final EntityManagerFactory emf) {
final JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
@Bean(name = "warehouseExceptionTranslation")
public PersistenceExceptionTranslationPostProcessor warehouseExceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
现在我得到：
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'entityManagerFactory' threw exception; nested exception is java.lang.IllegalArgumentException: dataSource or dataSourceClassName or jdbcUrl is required. at deployment.datalis_rest_api.war//org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:185)

Caused by: java.lang.IllegalArgumentException: dataSource or dataSourceClassName or jdbcUrl is required.
回答：
更正两个entityManager bean的名称：productionEntityManager和WarehouseEntityManager
entityManagerFactoryRefin @EnableJpaRepositories是beanName引用，
所以用
@Configuration@EnableJpaRepositories(
basePackages = "org.datalis.plugin.production.entity",
entityManagerFactoryRef = "productionEntityManager",
transactionManagerRef = "productionTransactionManager"
)
@EnableTransactionManagement
public class ContextProductionDatasource {
...
@Primary
@Bean
public EntityManager productionEntityManager(EntityManagerFactory emf) {
return emf.createEntityManager();
}
和
@Configuration@EnableJpaRepositories(
basePackages = "org.datalis.plugin.warehouse.entity",
entityManagerFactoryRef = "warehouseEntityManager",
transactionManagerRef = "warehouseTransactionManager"
)
@EnableTransactionManagement
public class ContextWarehouseDatasource {
...
@Bean
public EntityManager warehouseEntityManager(EntityManagerFactory emf) {
return emf.createEntityManager();
}
你需要的属性名称的匹配@ConfigurationProperties，以财产的价值“ ”与’ ‘
使用 @ConfigurationProperties(prefix="spring.production-datasource")和
@ConfigurationProperties(prefix="spring.warehouse-datasource")
并确保您的类路径中有驱动程序
