There are several methods for handling transactions in JDBC (Java Database Connectivity): 1. Auto-commit mode: This is the default mode in JDBC, where each SQL statement is treated as an independent transaction and immediately committed to the database. The auto-commit mode can be set using the `setAutoCommit(boolean autoCommit)` method. 2. Manual-commit mode: In this mode, developers need to explicitly call the `commit()` method to submit the transaction or the `rollback()` method to roll back the transaction. The auto-commit mode can be turned off using the `setAutoCommit(false)` method.\u793a\u4f8b\u4ee3\u7801\u5982\u4e0b:<\/p>\n

try {\r\n
    Connection conn = DriverManager.getConnection(url, username, password);<\/p>\r\n
    conn.setAutoCommit(false); \/\/ \u8bbe\u7f6e\u4e3a\u624b\u52a8\u63d0\u4ea4\u6a21\u5f0f<\/p>\r\n

3. Savepoint: Savepoints are used to divide a transaction into multiple sub-transactions, allowing you to set a savepoint within a sub-transaction and rollback to that savepoint when needed. An example code is provided below:<\/p>\n
try {
<\/p>\r\n
    Connection conn = DriverManager.getConnection(url, username, password);<\/p>\r\n
    conn.setAutoCommit(false); \/\/ \u8bbe\u7f6e\u4e3a\u624b\u52a8\u63d0\u4ea4\u6a21\u5f0f<\/p>\r\n

    \/\/ \u2026<\/p>\r\n
    Savepoint savepoint = conn.setSavepoint(\u201csavepoint1\u201d); \/\/ \u8bbe\u7f6e\u4fdd\u5b58\u70b9<\/p>\r\n
    \/\/ \u6267\u884c\u4e00\u7cfb\u5217SQL\u8bed\u53e5<\/p>\r\n
    \/\/ \u2026<\/p>\r\n
    conn.rollback(savepoint); \/\/ \u56de\u6eda\u5230\u4fdd\u5b58\u70b9<\/p>\r\n
    conn.commit(); \/\/ \u63d0\u4ea4\u4e8b\u52a1\r\n} catch (SQLException e) {<\/p>\r\n
