HikariPool-1 - jdbcUrl is required with driverClassName

Question

I went back to programming my old program https://github.com/JonkiPro/REST-Web-Services. I\'ve updated Spring Boot from version 15.6 to version 2.0.0. I have encountered many pr

Answer 1

I had the same issue in another context. From the 79. Data Access - Configure a Custom DataSource

if you happen to have Hikari on the classpath, this basic setup does not work, because Hikari has no url property (but does have a jdbcUrl property)

Hikari is the default pool in spring boot 2.

so you can replace the config url: jdbc:postgresql:database -> jdbc-url: jdbc:postgresql:database

or you can keep the config but you need to define another Bean to handle the mapping (aliases)

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

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