SQL脚本文件执行器

处于项目需求，需要能够批量执行SQL脚本文件，需要由前台页面操作触发执行。

查找相关资料，发现 Ant 提供了 SQLExec 组件可以支持SQL文件的执行，测试效果不错。

以下是对 SQLExec 封装后支持批量执行的执行器组件。 

package com.ge.digital.spo.sql.execute.ant;
import java.io.File;

import org.apache.tools.ant.Project;
import org.apache.tools.ant.taskdefs.SQLExec;
import org.apache.tools.ant.types.EnumeratedAttribute;  
  
public class AntSqlRunner {  
  
    public void runSqlScript() {  
        String driverClass = "com.mysql.jdbc.Driver";  
        String url = "jdbc:mysql://127.0.0.1/test?useUnicode=true&characterEncoding=utf-8";  
        String username = "root";  
        String password = "mysql";
        String targetSqlFolder = "/home/ca6417/upload/RecoverySQL/";  // 存放SQL脚本的目录
        String logOutputFolder = "/home/ca6417/upload/RecoverySQL/";  // 执行结果输出目录，出错的时候才会生成错误报告
        runSqlScriptFiles(driverClass, url, username, password, targetSqlFolder, logOutputFolder);
    }
    
    public static void runSqlScriptFiles(String driverClass, String url, String username, String password, String targetSqlFolder,
            String logOutputFolder) {
        SQLExec sqlExec = new SQLExec();  
        sqlExec.setDriver(driverClass);  
        sqlExec.setUrl(url);  
        sqlExec.setUserid(username);  
        sqlExec.setPassword(password);  
        // 如果执行过程有语句出错时如何处理，可以选择继续执行或停止.  
        sqlExec.setOnerror((SQLExec.OnError) (EnumeratedAttribute.getInstance(SQLExec.OnError.class, "stop")));  
        sqlExec.setPrint(true);  
        sqlExec.setProject(new Project());
        String targetSqlFile = targetSqlFolder;
        if(!new File(targetSqlFolder).isDirectory()) {
            targetSqlFolder = new File(targetSqlFolder).getParentFile().getAbsolutePath();
        }
        runSqlScript(sqlExec, targetSqlFile, targetSqlFolder, logOutputFolder);
    }

    private static void runSqlScript(SQLExec sqlExec, String targetFile, String targetSqlFolder, String logOutputFolder) {
        File file = new File(targetFile);
        if(file.isDirectory()) {
　　　　　　　 // 如果是目录，遍历执行所有脚本
            for(File f :file.listFiles()) {
                String fileStr = f.getAbsolutePath();
                runSqlScript(sqlExec, fileStr, file.getAbsolutePath(), logOutputFolder);
            }
        } else {
　　　　　　  // 如果是脚本文件，执行SQL脚本
            String targetSqlFile = targetFile;
            String logOutputFile = getLogOutputFile(logOutputFolder, targetSqlFolder, targetSqlFile);
            runSqlScriptFile(sqlExec, targetSqlFile, logOutputFile);
        }
    }

    private static void runSqlScriptFile(SQLExec sqlExec, String targetSqlFile, String logOutputFile) {
        sqlExec.setSrc(new File(targetSqlFile));  
        sqlExec.setOutput(new File(logOutputFile));  
        sqlExec.execute(); 
        System.out.println(targetSqlFile + " execute success.");
    }

    private static String getLogOutputFile(String logOutputFolder, String targetSqlFolder, String targetSqlFile) {
        String logFileName = targetSqlFile.substring(0, targetSqlFile.indexOf(".")) + ".txt";
        logFileName = logFileName.replace(targetSqlFolder, logOutputFolder);
        return logFileName;
    }  
}
