input之怎么清除默认值
@RequestMapping注解中的@RequestParam注解用于指定请求参数的默认值。默认情况下,如果请求中没有传递该参数,那么@RequestParam注解指定的参数就会使用默认值。在@RequestParam注解中,可以使用defaultValue属性来指定参数的默认值。例如,如果你在@RequestParam注解中设置了defaultValue="today",那么如果请求中没有传递该参数,那么该参数的默认值就会是"today"。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
