如何在Spring MVC中将正确的JSON传递给控制器​​？

Question

我无法弄清楚为什么在将POST请求传递给http://localhost:8080/company

时我会获得HTTP 415

我在POST请求中的JSON

{
    "id" : 7,
    "name" : "IBM"
}

这是我在控制器中的方法

@Controller
@RequestMapping("/company")
public class CompanyController {

    @Autowired
    CompanyRepository companyRepository;

    @RequestMapping(method = RequestMethod.GET,
            produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public Collection<Company> getAll() {
        return companyRepository.getCompanies();
    }

    @RequestMapping(method = RequestMethod.POST,
                    consumes = MediaType.APPLICATION_JSON_VALUE)
    public String add(@RequestBody Company company) {
        companyRepository.save(company);
        return "redirect:/company";
    }
}

我的实体

@Entity
@Table(name = "company")
public class Company implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

    @Column
    private String name;

    @JsonIgnore
    @OneToMany(mappedBy = "company")
    @LazyCollection(LazyCollectionOption.FALSE)
    private Collection<Employee> employees;

任何想法如何解决？

UPD：

回复消息：The server refused this request because the request entity is in a format not supported by the requested resource for the requested method

Answer 1

你会注意到你的方法是用

注释的

@RequestMapping(method = RequestMethod.POST,
                consumes = MediaType.APPLICATION_JSON_VALUE)

consumes是对@RequestMapping的限制，称此方法仅处理Content-Type application/json的请求。您的请求似乎没有该标头。你需要添加它。
