在 Spring Boot 中设置 DataSource 的属性

Question

I have multiple databases in spring boot One of the configuration for Oracle database is shown

import javax.sql.DataSource;
 
 
 @Bean 
public DataSource getDataSource() { 
    DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create(); 
    dataSourceBuilder.username("SA"); 
    dataSourceBuilder.password(""); 
    
    return dataSourceBuilder.build(); 
}
 
@Bean("OracleTemplate")
public JdbcTemplate jdbcTemplate()
{
     return new jdbcTemplate()
}

Now i want to set following properties for the Datasource .How can i set it?

validationOnquery
 validationQueryTimeout
 minIdle
 maxIdle
 testWhileIdle

Answer 1

Instead of returning datasource directly, you can store it as:

DataSource myDataSource = dataSourceBuilder.build();
myDataSource.minIdle = 0
myDataSource.validationQuery =
