spring-boot - Spring Boot 2.1.2 + POSTMAN + 415 Unsupported Media "application/json"
问题描述
我知道这个问题得到了多次回答，但不知何故我无法通过它。此外，我还没有发现Unsupported Media "application/json"错误。
编辑：@RequestBody 当我在 POSTMAN 中选择 x-www-form-urlencoded 但不使用 raw -> application/json 时有效
我只想通过从 POSTMAN 发布数据来创建记录。
这是我的代码：
Spring Boot 版本：2.1.2
我读到杰克逊数据绑定已经存在于 2.1.2 版本的 spring boot 中。
邮递员要求：
Body -> raw -> application/json
{
"first_name": "ashutosh",
"middle_name": "",
"last_name": "pandey",
"gender": "male",
"address": "my address"
}
或者
{
"firstName": "ashutosh",
"middleName": "",
"lastName": "pandey",
"gender": "male",
"address": "my address"
}
或者
{
"practitioner": {
"first_name": "ashutosh",
"middle_name": "",
"last_name": "pandey",
"gender": "male",
"address": "my address"
}
}
邮递员标题：
Content-Type: application/json
Accept: application/json

@RestController
@RequestMapping("/practitioner")
public class PractitionerController{
@Autowired private CrudService<Practitioner> crudService;
/**
* POST /create --> Create a new Practitioner and save it in the database.
*/
@PostMapping(consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> create(@RequestBody Practitioner practitioner)
{
crudService.save(practitioner);
String practitionerId = String.valueOf(practitioner.getId());
return ResponseEntity.ok().body(practitionerId);
}
}

public void setMiddleName(String middleName) { this.middleName = middleName; }
public void setPractitionerActions(Set<PractitionerAction> practitionerActions) { this.practitionerActions = practitionerActions; }
}
无论我做什么，我总是得到：

我尝试删除@RequestBody，添加consumes="application/json" 或consumes=MediaType.APPLICATION_JSON_VALUE，错误消失了，但我在数据库中得到空值。
我尝试创建一个简单的 html 表单并使用 jquery 提交数据，但同样的错误:(
<script type="text/javascript">
$(function(){
$("#btn").click(function(){
$.ajax({
url: 'http://localhost:8080/practitioner/',
method: 'post',
data: $("#form").serialize(),
dataType: 'json',
headers: {
'Authorization':'Bearer eyJhbGciOiJIUzI1NiJ9.eyJ1c2VyTmFtZSI6ImFkbWluIiwiaWF0IjoxNTU0MTcxNzA0fQ.o7AYTb8sE0iT5YMLndPUnkvdK5-sWG3u26gfK9z56ls',
'Content-Type':'application/json'
},
success: function(result){
console.log(result);
}
});
});
});
</script>
这是一个误导性错误吗？
这是错误堆栈跟踪：

解决方案
Change @PostMapping(headers="Accept=application/json") for @PostMapping(consumes = MediaType.APPLICATION_JSON_VALUE)
同样在 Postman 使用请求用户 CammelCase 而不是 _
例如
用户firstName而不是first_name, 或
您可以设置JsonProperties为 Practitioner 以根据需要接收属性。
