@ModelAttribute和@RequestBody和共存

当@ModelAttribute和@RequestBody同时存在时，@ModelAttribute注解将会被忽略，只有@RequestBody注解起作用。@ModelAttribute注解主要用于将方法的返回值绑定到具体的Model上，而@RequestBody注解用于将请求的内容绑定到方法的参数上，因此它们的作用是不同的。在同时使用时，@RequestBody注解会覆盖@ModelAttribute注解的效果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
