我在互联网上搜索解决了这个问题，但没有找到解决办法。请希望有人可以提供帮助。 在我的春季启动应用程序。我第一次使用hikari访问两个不同的数据源，但得到了上述错误。

提前致谢。
答案 0 :(得分：0)
我终于明白了。 我的Datasource1和Datasource2类缺少config.setJdbcUrl（url）
@Bean
public DataSource DataSourceTwo(){
HikariConfig config = new HikariConfig();
config.setDriverClassName(driver);
config.setJdbcUrl(url);
config.setUsername(username);
config.setPassword(password);
config.setAutoCommit(true);
return new HikariDataSource(config);
}
在我的LocalContainerEntityManagerFactoryBean中我也未能包含entityManagerFactoryBean.setDataSource（DataSourceTwo（））;
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBeanTwo() {
HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
entityManagerFactoryBean.setDataSource(DataSourceTwo());
entityManagerFactoryBean.setPackagesToScan("com.deanace.oauth2.entities");
return entityManagerFactoryBean;
}
