【前言】在做软件安装程序的时候;数据库信息都是我们自己配的，配完之后连接数据库-->执行我们准备好的指定的sql文件建表建库。我们这里主要用到的方法是：mybatis ScriptRunner

import org.apache.commons.configuration.Configuration;import org.apache.commons.configuration.PropertiesConfiguration;import org.apache.ibatis.io.Resources;import org.apache.ibatis.jdbc.ScriptRunner;import java.nio.charset.Charset;import java.sql.Connection;import java.sql.DriverManager;

private void connmysql(String sqlhost, String sqluser, String sqlpassword) {         Connection conn;         String url="JDBC:mysql://"+sqlhost+":3306/esn_single";         String username=sqluser;         String password=sqlpassword;        /*try {                Class.forName("com.mysql.jdbc.Driver");                conn= DriverManager.getConnection(url,username,password);                Statement st = conn.createStatement();                String sql ="SELECT * from company where companyID='695616997026708246117606'";                Set<String> hashSet = new HashSet<>();                ResultSet rs = st.executeQuery(sql);                String companyName;                while (rs.next()) {                    companyName=rs.getString("companyName");                    hashSet.add(companyName);                    //在控制台打印出来                    System.out.println(companyName);                }          } catch (Exception e) {              e.printStackTrace();          }*/        try {           /* Configuration configuration = new PropertiesConfiguration(ScriptRunnerExecSql.class.getClassLoader().getResource("")                    + "META-INF/spring/db.properties");*/            Class.forName("com.mysql.jdbc.Driver").newInstance();            conn =DriverManager.getConnection(url, username, password);            ScriptRunner runner = new ScriptRunner(conn);            Resources.setCharset(Charset.forName("GBK")); //设置字符集,不然中文乱码插入错误            runner.setLogWriter(null);//设置是否输出日志            //在resouse中新建一个文件夹：然后放入sql文件            runner.runScript(Resources.getResourceAsReader("sql/ceshi.sql"));            //runner.runScript(Resources.getResourceAsReader("sql/CC21-01.sql"));            runner.closeConnection();            conn.close();        } catch (Exception e) {            e.printStackTrace();        }    }

【结束语】

小编已亲自测过，可以完美批量执行sql文件成功！
