@notnull message

@NotNull注解的message属性是用来定义字段为空时抛出的自定义异常消息。在引用中的代码示例中，通过exception.getBindingResult().getFieldError().getDefaultMessage()方法可以获取到@NotNull注解中定义的message内容。这个方法会返回第一个字段错误的默认消息。如果想获取所有的错误信息，可以使用exception.getBindingResult().getFieldErrors()方法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
