我正在使用 JTDS 驱动程序将 Liquibase 从 Java 应用程序运行到 MSSQL。当我运行更新时,我看到它们显示出来,但实际上没有任何东西被提交到数据库。有任何想法吗?下面的代码在 Servlet 中运行。
Connection con = null;
try {
Properties props = new Properties();
props.load(getClass().getResourceAsStream("/datasource.properties"));
String driver = props.getProperty("database.driver");
String url = props.getProperty("database.url");
String username = props.getProperty("database.username");
String password = props.getProperty("database.password");
Class.forName(driver);
con = DriverManager.getConnection(url, username, password);
Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(new JdbcConnection(con));
Liquibase liquibase = new Liquibase("db.xml", new ClassLoaderResourceAccessor(), database);
response.getWriter().print("<PRE>");
liquibase.update("", response.getWriter());
con.commit();
} catch (Exception e) {
log.error(e.getMessage(), e);
throw new ServletException(e.getMessage(), e);
} finally {
if (con != null) {
try {
con.close();
} catch (SQLException e) {
log.warn(e.getMessage(), e);
}
}
}
response.flushBuffer();
