spring.datasource.url = [url]
spring.datasource.username = [username]
spring.datasource.password = [password]
spring.datasource.driverClassName = oracle.jdbc.OracleDriver
@Bean
@ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
return new DataSource();
}
这里的DataSource类具有属性url，用户名，密码，driverClassName，因此spring boot将它们映射到创建的对象。
DataSource类的示例：
public class DataSource {
private String url;
private String driverClassName;
private String username;
private String password;
//getters & setters, etc.
}
换句话说，这与使用构造型注解（@ Component，@ Service等）初始化某些bean的效果相同，例如
@Component
@ConfigurationProperties(prefix="spring.datasource")
public class DataSource {
private String url;
private String driverClassName;
private String username;
private String password;
//getters & setters, etc.
}
