HttpServletRequest 统一校验

HttpServletRequest 统一校验是通过在方法参数上添加注解实现的。在引用中的代码示例中，通过在@RequestParam注解中添加@NotBlank(message = "编号不允许为空")注解，可以对code参数进行非空校验。同样地，在引用中的代码示例中，通过在@RequestParam注解中添加@NotBlank(message = "昵称不允许为空")注解，可以对name参数进行非空校验。这样，在接收到请求时，如果对应的参数为空，会返回相应的错误信息。这种方式可以统一进行参数校验，避免重复的校验逻辑代码，提高了代码的可维护性和可读性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
