JSF 标准转换器&验证器文档-优快云博客

本文档列举了JavaServer Faces (JSF) 中一系列内置的标准数据类型转换器，包括BigDecimalConverter、BigIntegerConverter等，并详细介绍了这些转换器如何用于字符串与其他特定Java数据类型之间的相互转换。此外，还提供了使用这些标准转换器的三种方法。

The rest of the built-in converters do not have their own tags. These standard converters are registered in JSF for a specific data type:

Type	Class	Name	For conversion between...
BigDecimal	`BigDecimalConverter`	`javax.faces.BigDecimal`	String and `java.math.BigDecimal` values
BigInteger	`BigIntegerConverter`	`javax.faces.BigInteger`	String and `java.math.BigInteger` values
Boolean and boolean	`BooleanConverter`	`javax.faces.Boolean`	String and `java.lang.Boolean` (and boolean primitive) values
Byte and byte	`ByteConverter`	`javax.faces.Byte`	String and `java.lang.Number` values
Character and char	`CharacterConverter`	`javax.faces.Character`	String and `java.lang.Character` (and char primitive) values
Double and double	`DoubleConverter`	`javax.faces.Double`	String and `java.lang.Double` (and double primitive) values
Float and float	`FloatConverter`	`javax.faces.Float`	String and `java.lang.Float` (and float primitive) values
Integer and int	`IntegerConverter`	`javax.faces.Integer`	String and `java.lang.Integer` (and int primitive) values
Long and long	`LongConverter`	`javax.faces.Long`	String and `java.lang.Long` (and long primitive) values
Short and short	`ShortConverter`	`javax.faces.Short`	String and `java.lang.Short` (and short primitive) values

You can use standard converters that do not have supplied tags in one of three ways:

Specify the converter attribute on a component using a fully qualified class name or a converter name.
Nest the f:converter tag within a component. Use this tag's converterId attribute to reference the converter's name.
