尝试启动我的Spring应用程序时出现以下错误
ERROR 5908 --- [ main] com.zaxxer.hikari.HikariConfig : HikariPool-1 - dataSource or dataSourceClassName or jdbcUrl is required.
我的application.properties
文件如下:
spring.datasource.one.jdbc-url = jdbc:postgresql://10.x.x.x:y/sampledb1
spring.datasource.one.username = someuser
spring.datasource.one.password = somepasswd
spring.datasource.one.driver-class-name = org.postgresql.Driver
spring.datasource.two.jdbc-url = jdbc:postgresql://10.x.x.x:z/sampledb2
spring.datasource.two.username = someuser
spring.datasource.two.password = somepassword
spring.datasource.two.driver-class-name = org.postgresql.Driver
我正在使用DataSourceBuilder类,如下所示:
@Configuration
public class DataSourceConfig
{
@Bean(name = "one")
@Primary
@ConfigurationProperties(prefix = "spring.datasource.one")
public DataSource dataSource1()
{
return DataSourceBuilder.create().build();
}
@Bean(name = "two")
@ConfigurationProperties(prefix = "spring.datasource.two")
public DataSource dataSource2()
{
return DataSourceBuilder.create().build();
}
}
我的pom看起来像这样。

此功能之前工作正常,但现在引起了一些问题。并且错误发生intermittently
,有时它开始时没有错误,而其他时候却由于错误而失败。
我尝试了link中建议的解决方案。它们似乎对我不起作用。
答案 0 :(得分:0)
将jdbc-url
更改为jdbcUrl
,以便Hikari可以为每个URL找到合适的驱动程序。
jdbcUrl 此属性指示HikariCP使用“基于DriverManager的”配置。我们认为基于数据源的配置(上文)优于多种原因(请参见下文),但是对于许多部署而言,差异不大。当将此属性与“旧”驱动程序一起使用时,您可能还需要设置driverClassName属性,但首先尝试不使用该属性。请注意,如果使用此属性,则仍可以使用DataSource属性来配置驱动程序,实际上,建议您对URL本身中指定的驱动程序参数进行推荐。默认值:无
