As explained in the comments by both user7790438and nbrooks, the issue is that your response will be plain text (Success...), even though you tell it to load JSON (by providing the Content-Type: application/jsonheader).
正如user7790438和nbrooks的评论中所解释的，问题是您的响应将是纯文本 ( Success...)，即使您告诉它加载 JSON（通过提供Content-Type: application/json标头）。
To return JSON, you should return some kind of object, for example, you could create a ProjectStatusclass like this:
要返回 JSON，您应该返回某种对象，例如，您可以创建一个ProjectStatus这样的类：
public class ProjectStatus {
private String status;
public ProjectStatus(String status) {
this.status = status;
}
public String getStatus() {
return status;
}
}
Now, in your REST controller you should return a ResponseEntity<ProjectStatus>, like this:
现在，在您的 REST 控制器中，您应该返回 a ResponseEntity<ProjectStatus>，如下所示：
return new ResponseEntity<ProjectStatus>(new ProjectStatus("Success..."), HttpStatus.OK);
This will result in the following JSON when you use Postman:
当您使用 Postman 时，这将产生以下 JSON：
{"status": "Success..."}
You can pretty much return any object you'd like. An example would be to return the created project in your response.
您几乎可以返回任何您想要的对象。一个例子是在您的响应中返回创建的项目。
Alternatively, if you don't need JSON, you could provide the Content-Type: text/plainheader.
或者，如果您不需要 JSON，则可以提供Content-Type: text/plain标头。
