Error: org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'text/plain;charset=UTF-8' not supported
提问by Nir
I'm newbie in Spring Data.
I keep getting the error: org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'text/plain;charset=UTF-8' not supportedI've tried to change consumes inside @RequestMappingannotation to text/plainbut unfortunately it didn't help.*
我是 Spring Data 的新手。我不断收到错误消息：org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'text/plain;charset=UTF-8' not supported我尝试将内部@RequestMapping注释中的消耗更改为text/plain但不幸的是它没有帮助。*
Any ideas?
有任何想法吗？
Thanks,
谢谢，

Here is the exception I get:
这是我得到的例外：

Building on what is mentioned in the comments, the simplest solution would be:
基于评论中提到的内容，最简单的解决方案是：
@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {
//whatever
}
class SomeDto {
private List<WhateverBudgerPerDateDTO> budgetPerDate;
//getters setters
}
The solution assumes that the HTTP request you are creating actually has
该解决方案假定您正在创建的 HTTP 请求实际上具有
Content-Type:application/jsoninstead of text/plain
Content-Type:application/json代替 text/plain

For me it turned out that I had a @JsonManagedReferecein one entity without a @JsonBackReferencein the other referenced entity. This caused the marshaller to throw an error.
对我来说，事实证明我@JsonManagedReferece在一个实体中有一个，而@JsonBackReference在另一个引用实体中有一个。这导致编组器抛出错误。

Ok - for me the source of the problem was in serialisation/deserialisation. The object that was being sent and received was as follows where the code is submitted and the code and maskedPhoneNumber is returned.
好的 - 对我来说问题的根源在于序列化/反序列化。正在发送和接收的对象如下，其中提交代码并返回代码和 maskedPhoneNumber。
@ApiObject(description = "What the object is for.")
@JsonIgnoreProperties(ignoreUnknown = true)
public class CodeVerification {
@ApiObjectField(description = "The code which is to be verified.")
@NotBlank(message = "mandatory")
private final String code;
@ApiObjectField(description = "The masked mobile phone number to which the code was verfied against.")
private final String maskedMobileNumber;
public codeVerification(@JsonProperty("code") String code, String maskedMobileNumber) {
this.code = code;
this.maskedMobileNumber = maskedMobileNumber;
}
public String getcode() {
return code;
}
public String getMaskedMobileNumber() {
return maskedMobileNumber;
}
}
The problem was that I didn't have a JsonProperty defined for the maskedMobileNumber in the constructor. i.e. Constructor should have been
问题是我没有在构造函数中为 maskedMobileNumber 定义 JsonProperty。即构造函数应该是
public codeVerification(@JsonProperty("code") String code, @JsonProperty("maskedMobileNumber") String maskedMobileNumber) {
this.code = code;
this.maskedMobileNumber = maskedMobileNumber;
}
