springboot使用jdbc优雅的配置数据源

		
			org.springframework.boot
			spring-boot-starter-web
		
		
		
			com.alibaba
			druid
			1.2.11
		
		
		
			mysql
			mysql-connector-java
		

		
			org.springframework.boot
			spring-boot-starter-test
			test
		
	

在springboot的配置文件application.properties加入:

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

@Configuration   //当前类作为配置类使用
public class DruidConfig {

    @Bean
    
    @ConfigurationProperties(prefix = "jdbc")
    public DruidDataSource getDateSource(){
        DruidDataSource druid=new DruidDataSource();
       
        return druid;
    }
}
