org.springframework.http.converter.httpmessagenotradableExce

Question

im在我的春季启动应用程序中使用Mockito进行JUNIT测试。我正在嘲笑控制器应该调用的存储库。在运行400个响应代码(Get Works Fiest(运行后测试时，我将获得httpmessagenotreadable Exception。

这是正在测试的控制器

import org.springframework.dao.EmptyResultDataAccessException;

@RestController
@RequestMapping(path="abouts",
                produces="application/json",
                consumes="application/json")
@CrossOrigin(origins="*")
public class AboutController {
    private AboutRepository aboutRepo;
    public AboutController(AboutRepository aboutRepo) {
        this.aboutRepo = aboutRepo;
    }
    @PostMapping
    @ResponseStatus(HttpStatus.CREATED)
    public About postAbout(@RequestBody About about) {
        return aboutRepo.save(about);
    }
}

看起来大约是JSON无效。您可以在内容方法上使用双引号的JSON尝试吗？

{ "id":null, "position":null, "name":"Test", "description":null, "image":null }
