本文主要介绍了spring.datasource.schema配置，文中通过示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

用springboot2.0执行sql脚本：

1.现将sql文件放在resources下的sql文件夹下

2.新建数据库mybatis

3.配置yml

spring:
datasource:
#   数据源基本配置
  username: root
  password: 123
  driver-class-name: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/mybatis?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
  type: com.alibaba.druid.pool.DruidDataSource
#   数据源其他配置
  initialSize: 5
  minIdle: 5
  maxActive: 20
  maxWait: 60000
  timeBetweenEvictionRunsMillis: 60000
  minEvictableIdleTimeMillis: 300000
  validationQuery: SELECT 1 FROM DUAL
  testWhileIdle: true
  testOnBorrow: false
  testOnReturn: false
  poolPreparedStatements: true
#   配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
  filters: stat,wall,log4j
  maxPoolPreparedStatementPerConnectionSize: 20
  useGlobalDataSourceStat: true
  connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
  schema:
      - classpath:sql/department.sql
      - classpath:sql/employee.sql
  initialization-mode: ALWAYS

配置类：

package com.example.springbooy06datamybatis.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;

@Configuration
public class DruidConfig {

  @ConfigurationProperties(prefix = "spring.datasource")
  @Bean
  public DataSource druid(){
      return  new DruidDataSource();
  }

  //配置Druid的监控
  //1、配置一个管理后台的Servlet
  @Bean
  public ServletRegistrationBean statViewServlet(){
      ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
      Map<String,String> initParams = new HashMap<>();

      initParams.put("loginUsername","admin");
      initParams.put("loginPassword","123456");
      initParams.put("allow","");//默认就是允许所有访问
      initParams.put("deny","192.168.15.21");

      bean.setInitParameters(initParams);
      return bean;
  }


  //2、配置一个web监控的filter
  @Bean
  public FilterRegistrationBean webStatFilter(){
      FilterRegistrationBean bean = new FilterRegistrationBean();
      bean.setFilter(new WebStatFilter());

      Map<String,String> initParams = new HashMap<>();
      initParams.put("exclusions","*.js,*.css,/druid/*");

      bean.setInitParameters(initParams);

      bean.setUrlPatterns(Arrays.asList("/*"));

      return  bean;
  }
}

执行成功！：
