java 执行sql脚本.docx
java执行sql文件这个问题麻烦的地方在于解析sql脚本文件。所幸的是ant与 ibatis提供了这种实现。package com.unmi; import java.io.*; import org.apache.tools.ant.*; import org.apache.tools.ant.taskdefs.*; import org.apache.tools.ant.types.*; /* * 调用 ant.jar 的 SQLExec 执行 SQL 脚本文件 * author Unmi */ public class AntExecSql /* * param args */ public static void main(String args) SQLExec sqlExec = new SQLExec(); /设置数据库参数 sqlExec.setDriver("oracle.jdbc.driver.OracleDriver"); sqlExec.setUrl("jdbc:oracle:thin:10.128.x.x:1521:xxsid"); sqlExec.setUserid("xxuser"); sqlExec.setPassword("xxpass"); /要执行的脚本 sqlExec.setSrc(new File("src/data.sql"); /有出错的语句该如何处理 sqlExec.setOnerror(SQLExec.OnError)(EnumeratedAttribute.getInstance( SQLExec.OnError.class, "abort"); sqlExec.setPrint(true); /设置是否输出 /输出到文件 sql.out 中；不设置该属性，默认输出到控制台 sqlExec.setOutput(new File("src/sql.out"); sqlExec.setProject(new Project(); / 要指定这个属性，不然会出错 sqlExec.execute(); package com.unmi;import java.io.*;import org.apache.tools.ant.*;import org.apache.tools.ant.taskdefs.*;import org.apache.tools.ant.types.*;/* 调用 ant.jar 的 SQLExec 执行 SQL 脚本文件* author Unmi*/public class AntExecSql /* param args*/public static void main(String args) SQLExec sqlExec = new SQLExec();/设置数据库参数sqlExec.setDriver("oracle.jdbc.driver.OracleDriver");sqlExec.setUrl("jdbc:oracle:thin:10.128.x.x:1521:xxsid");sqlExec.setUserid("xxuser");sqlExec.setPassword("xxpass");/要执行的脚本sqlExec.setSrc(new File("src/data.sql");/有出错的语句该如何处理sqlExec.setOnerror(SQLExec.OnError)(EnumeratedAttribute.getInstance(SQLExec.OnError.class, "abort");sqlExec.setPrint(true); /设置是否输出/输出到文件 sql.out 中；不设置该属性，默认输出到控制台sqlExec.setOutput(new File("src/sql.out");sqlExec.setProject(new Project(); / 要指定这个属性，不然会出错sqlExec.execute();ibatis：package com.ibatis.jpetstore.test;import java.sql.DriverManager;import java.util.Properties;import mon.jdbc.ScriptRunner;import mon.resources.Resources;import com.mysql.jdbc.Connection;public class DBTestSQL public static void main(String args) try Properties props = Resources.getResourceAsProperties("properties/database.properties"); String url = props.getProperty("url"); String driver = props.getProperty("driver"); String username = props.getProperty("username"); String password = props.getProperty("password"); System.out.println(url); if(url.equals("jdbc:mysql:/localhost:3306/jpetstore1") Class.forName(driver).newInstance(); Connection conn = (Connection) DriverManager.getConnection(url, username, password); ScriptRunner runner = new ScriptRunner(conn, false, false); runner.setErrorLogWriter(null); runner.setLogWriter(null); runner.runScript(Resources.getResourceAsReader("ddl/mysql/jpetstore-mysql-schema.sql"); runner.runScript(Resources.getResourceAsReader("ddl/mysql/jpetstore-mysql-dataload.sql"); catch (Exception e) e.printStackTrace(); ScriptRunner(mon.jdbc.*)用法ScriptRunner类用于执行SQL语句,例如创建数据库schema，或传入缺省或测试数据库等等。 从下面的例子可以认识到它的易用性: 例子1：使用现成的数据库连接 Connection conn=getConnection();/some method to get a Connection ScriptRunner runner=new ScriptRunner(); runner.runScript(conn,Resources.getResourceAsReader("com/some/resource/path/initialize.sql"); conn.close(); 例子2：使用新的数据库连接 ScriptRunner runner=new ScriptRunner("com.some.Driver","jdbc:url:/db","login","password"); runner.runScript(conn,new FileReader("/user/local/db/scripts/initialize-db.sql");例子3：使用新创建的数据连接 Properties props= getProperties();/some properties form somewhereScriptRunner runner =new ScriptRunner(props);runner.runScript(conn,new FileReader("/user/local/db/scripts/initialize-db.sql");
