如何在Spring MVC中将正确的JSON传递给控制器​​？ [英] How to pass correct JSON to contoller in Spring MVC?

问题描述

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

I can't figure out why I'm get HTTP 415 when pass POST request to http://localhost:8080/company

我在POST请求中的JSON

My JSON in POST request

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

这是我在控制器中的方法

Here is my method in controller

@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：

响应消息：服务器拒绝了此请求，因为请求实体的格式不受请求方法所请求的资源支持

推荐答案

您会注意到您的方法是用

You'll notice your method is annotated with

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

消费是 @RequestMapping 的限制说此方法仅处理 Content-Type application / json 的请求。您的请求似乎没有该标头。你需要添加它。

The consumes is a restriction for the @RequestMapping saying that this method will only handle requests that have a Content-Type of application/json. Your request doesn't seem to have that header. You need to add it.
