spring-boot - Spring 正在寻找 PostgreSql 驱动程序，但我使用的是 JTDS

Question

加载 spring 云数据流应用程序失败并显示此日志：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: org.postgresql.Driver

但是配置是：

spring.jpa.database=sybase
spring.datasource.url=jdbc:jtds:sybase://xxx:X000/xxxx;autoCommit=false;appName=dataflow
spring.datasource.username=xx
spring.datasource.password=xxx
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver
spring.datasource.hikari.driver-class-name=net.sourceforge.jtdatasource.jdbc.Driver
spring.datasource.hikari.pool-name=datasource-pool
spring.datasource.hikari.connection-timeout=3000
spring.datasource.hikari.maximum-pool-size=2
spring.datasource.hikari.minimum-idle=0
spring.datasource.hikari.connection-test-query=SELECT 1
spring.datasource.hikari.auto-commit=false
spring.datasource.hikari.transaction-isolation=TRANSACTION_READ_COMMITTED

依赖：

    <dependency>
        <groupId>net.sourceforge.jtds</groupId>
        <artifactId>jtds</artifactId>
        <version>1.3.1</version>
    </dependency>

从未指定 PostgreSql。

使用弹簧靴 2.3.3

更新：

我认为 spring 数据流上下文中的某些内容正在设置驱动程序，因为如果我创建自己的配置类并且不使用 spring.datasource 前缀，它就可以工作：

@Configuration
public class DataSourceConfiguration {
    @Bean
    @Primary
    @ConfigurationProperties("spring.ds")
    public DataSourceProperties dataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @Primary
    @ConfigurationProperties("spring.ds.hikari")
    public HikariDataSource sybaseDataSource() {
        return dataSourceProperties().initializeDataSourceBuilder().type(HikariDataSource.class).build();
    }
}
