Springboot配置jdbc数据源

2，通过自定义配置文件配置数据源信息

3，创建配置类

package com.bdqn.springbootjdbc.config;

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;

import javax.sql.DataSource;

/*
* 数据源的JDBC配置类
* */
@Configuration
@PropertySource("classpath:/jdbc.properties")//加载指定的jdbc配置文件
public class JdbcConfiguraction {

    @Value("${jdbc.driverClassName}")
    private String driverClassName;
    @Value("${jdbc.url}")
    private String url;
    @Value("${jdbc.username}")
    private String username;
    @Value("${jdbc.password}")
    private String password;
    /*实例化Druid*/
    @Bean
    public DataSource getDataSource()
    {
        DruidDataSource source=new DruidDataSource();
        source.setDriverClassName(this.driverClassName);
        source.setUrl(this.url);
        source.setUsername(this.username);
        source.setPassword(this.password);
        return source;
    };
}

4，测试结果 设置断点测试
