枚举 LiteralHandlingMode

  • 所有已实现的接口:
    Serializable, Comparable<LiteralHandlingMode>
    public enum LiteralHandlingMode
extends Enum<LiteralHandlingMode>
    This enum defines how literals are handled by JPA Criteria. By default (AUTO), Criteria queries uses bind parameters for any literal that is not a numeric value. However, to increase the likelihood of JDBC statement caching, you might want to use bind parameters for numeric values too. The BIND mode will use bind variables for any literal value. The INLINE mode will inline literal values as-is. To prevent SQL injection, never use INLINE with String variables. Always use constants with the INLINE mode.

    • 方法详细资料

      • values

        public static LiteralHandlingMode[] values()
        按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: 
        for (LiteralHandlingMode c : LiteralHandlingMode.values())
    System.out.println(c);
        返回:
        按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

      • valueOf

        public static LiteralHandlingMode valueOf​(String name)
        返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
        参数:
        name - 要返回的枚举常量的名称。
        返回:
        返回带有指定名称的枚举常量
        抛出:
        IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量
        NullPointerException - 如果参数为空值

      • interpret

        public static LiteralHandlingMode interpret​(Object literalHandlingMode)
        Interpret the configured literalHandlingMode value. Valid values are either a LiteralHandlingMode object or its String representation. For string values, the matching is case insensitive, so you can use either AUTO or auto.
        参数:
        literalHandlingMode - configured LiteralHandlingMode representation
        返回:
        associated LiteralHandlingMode object
