Running a .sql script using MySQL with JDBC

Ok. You can use this class here (posted on pastebin because of file length) in your project. But remember to keep the apache license info.

JDBC ScriptRunner

It's ripoff of the iBatis ScriptRunner with dependencies removed.

You can use it like this

Connection con = ....
ScriptRunner runner = new ScriptRunner(con, [booleanAutoCommit], [booleanStopOnerror]);
runner.runScript(new BufferedReader(new FileReader("test.sql")));

That's it!

I did a lot of research on this and found a good util from spring. I think using SimpleJdbcTestUtils.executeSqlScript(...) is actually the best solution, as it is more maintained and tested.

Edit: SimpleJdbcTestUtils is deprecated. You should use JdbcTestUtils. Updated the link.

Spring Framework's ResourceDatabasePopulator may help. As you said you're using MySQL and JDBC, let's assume you have a MySQL-backed DataSource instance ready. Further, let's assume your MySQL script files are classpath-locatable. Let's assume you are using WAR layout and the script files are located in a directory src/main/webapp/resources/mysql-scripts/... or src/test/resources/mysql-scripts/.... Then you can use ResourceDatabasePopulator to execute SQL scripts like this:

import org.springframework.jdbc.datasource.init.ResourceDatabasePopulator;
import javax.sql.DataSource;

DataSource dataSource = getYourMySQLDriverBackedDataSource();

ResourceDatabasePopulator rdp = new ResourceDatabasePopulator();    
rdp.addScript(new ClassPathResource(
                        "mysql-scripts/firstScript.sql"));
rdp.addScript(new ClassPathResource(
                        "mysql-scripts/secondScript.sql"));

try {
        Connection connection = dataSource.getConnection();
        rdp.populate(connection); // this starts the script execution, in the order as added
    } catch (SQLException e) {
        e.printStackTrace();
    }
