能让Connection支持断点吗（Savepoint ）？

[JoyceLikeRose]

我看到光连接池有支持，BeeCP没有，您能增加一下吗？

你自己可以加上，检验没有问题，再合并到项目中去。

关于光连接池 我做了一个验证例子

分享测试性代码

public class SavePointTest {
    public static void main(String[] ags) throws Exception {
        testHikari();
        testBeeCP();
    }

    private static void testHikari() throws Exception {
        HikariConfig config = new HikariConfig();
        config.setJdbcUrl("jdbc:mysql://localhost/test");
        config.setDriverClassName("com.mysql.jdbc.Driver");
        config.setUsername("root");
        config.setPassword("");
        config.setMinimumIdle(1);
        config.setMaximumPoolSize(1);
        config.setConnectionTimeout(8000);
        config.setConnectionTestQuery("select 1 from dual");
        config.setAutoCommit(false);
        HikariDataSource dataSource = new HikariDataSource(config);

        Connection conn = dataSource.getConnection();
        testSavepoint(conn, "Hikari");
        conn = dataSource.getConnection();
        conn.setAutoCommit(true);
        conn.close();
    }

    private static void testBeeCP() throws Exception {
        BeeDataSourceConfig config = new BeeDataSourceConfig();
        config.setDriverClassName("com.mysql.jdbc.Driver");
        config.setJdbcUrl("jdbc:mysql://localhost/test");
        config.setUsername("root");
        config.setPassword("");
        config.setMaxActive(1);
        config.setInitialSize(1);
        config.setMaxWait(8000);
        config.setDefaultAutoCommit(false);
        BeeDataSource dataSource = new BeeDataSource(config);

        Connection conn = dataSource.getConnection();
        testSavepoint(conn, "BeeCP");
        conn = dataSource.getConnection();
        conn.setAutoCommit(true);
        conn.close();
    }

    public static void testSavepoint(Connection conn, String dsName) throws SQLException {
        Statement ptmt = null;
        Savepoint save1 = null;
        Savepoint save2 = null;
        Savepoint save3 = null;
        try {
            conn.setAutoCommit(false);
            ptmt = conn.createStatement();
            ptmt.execute("insert into SAVE_POINT(DS_NAME) values('" + dsName + "_0')");
            save1 = conn.setSavepoint("1");
            ptmt.execute("insert into SAVE_POINT(DS_NAME) values('" + dsName + "_1')");
            save2 = conn.setSavepoint("2");
            ptmt.execute("insert into SAVE_POINT(DS_NAME) values('" + dsName + "_2')");
            save3 = conn.setSavepoint("3");
            ptmt.execute("insert into SAVE_POINT(DS_NAME) values('" + dsName + "_3')");
            conn.rollback(save1);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (ptmt != null)
                ptmt.close();
            if (conn != null)
                conn.close();
        }
    }
}

执行前

执行后

BeeCP没有将rollback(SavePoint)方法与事务脏标记关联，因此运行上去代码是没有问题的，如果光连接池取消的话，上述代码是可以通过的。
