1，加入依赖

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
