本文整理了Java中org.apache.commons.lang3.Validate.validState()方法的一些代码示例，展示了Validate.validState()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Validate.validState()方法的具体详情如下：
包路径：org.apache.commons.lang3.Validate
类名称：Validate
方法名：validState

Validate.validState介绍

[英]Validate that the stateful condition is true; otherwise throwing an exception. This method is useful when validating according to an arbitrary boolean expression, such as validating a primitive number or using your own custom validation expression.

Validate.validState(field > 0); 
Validate.validState(this.isOk());

The message of the exception is "The validated state is false".
[中]验证状态条件为真；否则将引发异常。当根据任意布尔表达式进行验证时，此方法非常有用，例如验证基元数或使用自己的自定义验证表达式。

Validate.validState(field > 0); 
Validate.validState(this.isOk());

异常的消息是“已验证状态为false”。
