code: public static void isFalse(boolean expression, String errorMsgTemplate, Object... params) throws IllegalArgumentException {
  		if (expression) {
  			throw new IllegalArgumentException(StrUtil.format(errorMsgTemplate, params));
  		}
  	}
docs: 断言是否为假，如果为 {@code true} 抛出 {@code IllegalArgumentException} 异常<br>
  
  <pre class="code">
  Assert.isFalse(i &lt; 0, "The value must be greater than zero");
  </pre>
  
  @param expression 波尔值
  @param errorMsgTemplate 错误抛出异常附带的消息模板，变量用{}代替
  @param params 参数列表
  @throws IllegalArgumentException if expression is {@code false}
