所有已实现的接口:

public class NumberBinder
extends java.beans.PropertyEditorSupport

绑定的策略：当request中有与bean中相同的PropertyName时，就把request的Parameter值注入，当该值为null时，则跳过，保留bean的原有值

NumberBinder

public NumberBinder(java.lang.Class numberClass,
                    boolean allowEmpty)
             throws java.lang.IllegalArgumentException

Create a new CustomNumberEditor instance, using the default valueOf methods for parsing and toString methods for rendering.

The "allowEmpty" parameter states if an empty String should be allowed for parsing, i.e. get interpreted as null value. Else, an IllegalArgumentException gets thrown in that case.

参数:

numberClass - Number subclass to generate

allowEmpty - if empty strings should be allowed

抛出:

java.lang.IllegalArgumentException - if an invalid numberClass has been specified

NumberBinder

public NumberBinder(java.lang.Class numberClass,
                    java.text.NumberFormat numberFormat,
                    boolean allowEmpty)
             throws java.lang.IllegalArgumentException

Create a new CustomNumberEditor instance, using the given NumberFormat for parsing and rendering.

The allowEmpty parameter states if an empty String should be allowed for parsing, i.e. get interpreted as null value. Else, an IllegalArgumentException gets thrown in that case.

参数:

numberClass - Number subclass to generate

numberFormat - NumberFormat to use for parsing and rendering

allowEmpty - if empty strings should be allowed

抛出:

java.lang.IllegalArgumentException - if an invalid numberClass has been specified
