插入H2数据库NotSerializableException：org.springframework.jdbc.support.GeneratedKeyHolder“ [90026-196]

Question

以下代码，尝试使用ID列作为表的主键插入H2数据库表。 ID值应自动生成！

我真的需要在开始生产之前在H2轻量级数据库中测试我的应用程序逻辑。

public Customer addCustomer(Customer c) {
    String sql = "INSERT INTO Customer_Tbl(FirstName, LastName, Email, PhoneNumber, CreatedById, Status, Version)"
                + "VALUES (?, ?, ?, ?, ?, ?, ?)";

    KeyHolder keyHolder = new GeneratedKeyHolder();

    Db.update(sql, new Object[] {c.getFirstName(), c.getLastName(), c.getEmail(), c.getPhoneNumber(), c.getCreatedById(), 1, 0},  keyHolder);

    long id = (long)keyHolder.getKey();

    return getCustomerById(id);
}

并且Db是数据成员：

private JdbcTemplate Db;

这将引发以下异常，任何帮助。

org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO Customer_Tbl(FirstName, LastName, Email, PhoneNumber, CreatedById, Status, Version)VALUES (?, ?, ?, ?, ?, ?, ?)]; SQL state [90026]; error code [90026]; Serialization failed, cause: "java.io.NotSerializableException: org.springframework.jdbc.support.GeneratedKeyHolder" [90026-196]; nested exception is org.h2.jdbc.JdbcSQLException: Serialization failed, cause: "java.io.NotSerializableException: org.springframework.jdbc.support.GeneratedKeyHolder" [90026-196]
