Spring MVC：如何修复415响应错误

Question

由于我没有找到任何fox 415响应错误的工作示例，我仍然无法理解Spring为什么不能处理以下请求：

@RestController
@AllArgsConstructor
@RequestMapping("/organization")
@Slf4j
public class OrganizationController {
...
    @PutMapping(value = "/public-certificates")
    public List<CertificateDTO> updateCertificates(@RequestBody Map<String, String> body) {
        String companyNumber = body.getOrDefault("kbo", "unknown");
        List<CertificateDTO> certificates = organizationClient.updateCertificates(companyNumber);

        return certificates;
    }

并返回：

Completed 415 UNSUPPORTED_MEDIA_TYPE

以下是请求的一个CURL版本：

curl -X PUT -i http://localhost:8080/api/organization/public-certificates --data 'kbo=123.456.789'

Een修改后如下：

@PutMapping(value = "/public-certificates")
    public List<CertificateDTO> updateCertificates(@RequestBody CompanyNumber body) {
        String companyNumber = body.getKbo();
        List<CertificateDTO> certificates = organizationClient.updateCertificates(companyNumber);

        return certificates;
    }

    @Getter
    @Setter
    private class CompanyNumber {
        private String kbo;
    }

并使用curl如下所示：

url -H "Accept: application/json" -H "Content-Type:application/json" -X PUT -i http://localhost:8080/api/organization/public-certificates --data '{"kbo": "0316.380.940"}'

没有解决问题。

我错过了什么？

Answer 1

以下是对我有效的方法：

@RestController
@AllArgsConstructor
@RequestMapping("/organization")
@Slf4j
public class OrganizationController {
...
    @PutMapping(value = "/public-certificates")
    public List<CertificateDTO> updateCertificates(@RequestBody Map<String, String> body) {
        String companyNumber = body.getOrDefault("kbo", "unknown");
        List<CertificateDTO> certificates = organizationClient.updateCertificates(companyNumber);

        return certificates;
    }

使用以下CURL命令运行时：

curl -i -H "Accept: application/json" -H "Content-Type:application/json" -X PUT --data '{"kbo": "0316.380.940"}' "http://localhost:8080/api/organization/public-certificates"
