SpringBoot实战系列之@ConditionalOnExp

@Bean
@ConditionalOnExpression("!${database.isEmbedded:true}")
public ConnectionPool dataSourceMBean(DataSourceProxy dataSourceProxy) throws SQLException {
    return dataSourceProxy.createPool().getJmxPool();
}

在application.properties
写如下配置就不会是实例化这个bean

database.isEmbedded:true
