Question

我有带两个数据源的spring boot应用程序，其中一个每天晚上重新启动，我需要解决自动连接问题。我做了一些研究但是，任何解决方案都不起作用

我的dev.properties

datasource.post.url=jdbc:postgresql://…
datasource.post.driverClassName=org.postgresql.Driver
datasource.post.username=…
datasource.post.password=…

datasource.orl.url=jdbc:oracle:thin:@localhost:1521/spring
datasource.orl.driverClassName=oracle.jdbc.OracleDriver
datasource.orl.username=….
datasource.orl.password=…

我尝试添加到dev.properties

datasource.orl.test-on-borrow=true
datasource.orl.validation-query=SELECT 1

没用。我还将建议的版本添加到application.properties

spring.datasource.tomcat.testOnBorrow=true
spring.datasource.tomcat.validationQuery=SELECT 1

此版本同样不起作用，我甚至没有添加推荐的自动连接

jdbc:oracle:thin:@localhost:1521/spring?autoReconnect=true

但是当我重新启动tomcat时，我得到错误

编辑我扩展stackTrace信息和我的Orl datacourse配置类

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
@EnableTransactionManagement
@EnableJpaRepositories(
        basePackages = "com.xxx.orl.repository",
        entityManagerFactoryRef = "orlEntityManager",
        transactionManagerRef = "orlTransactionManager")
public class OrlDSConfiguration {

    @Bean(name = "orlDS")
    @ConfigurationProperties(prefix = "datasource.orl")
    public DataSource orlDataSource() {
        return DataSourceBuilder.create()
                .build();
    }

    @SuppressWarnings("SpringJavaAutowiringInspection")
    @Bean(name = "orlEntityManager")
    @Primary
    @PersistenceContext(unitName = "orl")
    public LocalContainerEntityManagerFactoryBean orlContainerEMFactory(@Qualifier("orlDS") DataSource ds, EntityManagerFactoryBuilder builder, JpaProperties jpaProperties) {
        Map<String, String> customProperties = jpaProperties.getHibernateProperties(ds);
        return builder.dataSource(ds)
                .persistenceUnit("orl")
                .properties(jpaProperties.getProperties())
                .properties(customProperties)
                .packages("com.xxx.orl.domain")
                .build();
    }

    @Bean(name = "orlTransactionManager")
    public PlatformTransactionManager orlTransactionManager(
            @Qualifier("orlEntityManager") EntityManagerFactory orlContainerEMFactory) {
        return new JpaTransactionManager(orlContainerEMFactory);
    }

}
