推荐答案

ResponseEntity 表示整个 HTTP 响应.除了 body 之外，它的 API 还允许您为响应设置 headers 和 状态代码.

ResponseEntity<T> represents the entire HTTP response. Besides the body, its API allows you to set headers and a status code to the response.

只返回一个 bean 很好，但不会给你太多的灵活性:将来，如果你需要在响应中添加一个 header 或修改状态代码，例如，你需要更改方法返回类型.

Returning just a bean is fine but doesn't give you much flexibility: In the future, if you need to add a header to the response or modify the status code, for example, you need to change the method return type.

有关返回值的更多详细信息，请参阅 Spring MVC 文档.
