我在SpringBootApplication中编写了非常基本的REST服务。当我试图点击api时,我得到了Unexpected 'S'

这样的回复

这是我的api,

@RestController
    @RequestMapping(value="/rally")
    public class CreateProjectApi {

        @RequestMapping(value = "/createProject", 
                produces = { "application/json" }, 
                consumes = { "application/json" }, 
                method = RequestMethod.GET)
        public ResponseEntity<String> createProj() {
            String s = "Success...";
            return new ResponseEntity<String>(s, HttpStatus.OK);
        }

    }

这是我的POM.XML,

我通过标题中的content-type:application/json通过邮递员点击api。但我得到了意想不到的“S”作为回应。我已按照此链接unexpected 's' in response of restful service但我没有得到任何解决方案。任何人都可以帮助我吗?

正如user7790438nbrooks的评论中所解释的那样,问题是您的回复将是纯文本(Success...),即使您告诉它加载JSON(通过提供Content-Type: application/json标题。

要返回JSON,您应该返回某种对象,例如,您可以创建一个ProjectStatus类,如下所示:

public class ProjectStatus {
    private String status;

    public ProjectStatus(String status) {
        this.status = status;
    }

    public String getStatus() {
        return status;
    }
}

现在,在您的REST控制器中,您应该返回ResponseEntity<ProjectStatus>,如下所示:

return new ResponseEntity<ProjectStatus>(new ProjectStatus("Success..."), HttpStatus.OK);

当您使用Postman时,这将产生以下JSON:

{"status": "Success..."}

您几乎可以返回任何您想要的对象。一个例子是在您的回复中返回创建的项目。

或者,如果您不需要JSON,则可以提供Content-Type: text/plain标题。
