我想在Spring Boot中配置2个JNDI数据源。我尝试了以下配置：

application.properties

spring.production-datasource.jndi-name=java:/global/production_gateway
spring.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：

    Caused by: java.lang.IllegalStateException: Unable to set value for property driver-class-name
        at deployment.datalis_rest_api.war//org.springframework.boot.context.properties.bind.JavaBeanBinder$BeanProperty.setValue(JavaBeanBinder.java:349)

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？

第二次尝试 ：

application.properties：

spring.production.datasource.jndi-name=java:/global/production_gateway
spring.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：
