我在另一个背景下也有同样的问题。从79号来的。数据访问-配置自定义数据源

如果您碰巧在类路径上有Hikari，这个基本设置就不起作用了，因为Hikari没有url属性（但有一个jdbcUrl属性）

Hikari是spring Boot2中的默认池。

@Bean
@Primary
@ConfigurationProperties("app.datasource")
public DataSourceProperties dataSourceProperties() {
    return new DataSourceProperties();
}

@Bean
@ConfigurationProperties("app.datasource")
public DataSource dataSource(DataSourceProperties properties) {
    return properties.initializeDataSourceBuilder().
        .build();
}
