@JsonProperty没有按预期工作 [英] @JsonProperty not working as expected

问题描述

当我使用Spring RestTemplate使用restful webservice时出现以下异常

I get the following exception when i consume a restful webservice using Spring RestTemplate

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "IMP-SourceTxnId" (class com.model.ResponseBaseParameters) not marked as ignorable (4 known properties: , "sourceTxnId", "incommTxnId", "responseCode", "responseText"])

响应参数是

{

  "responseBaseParameters":  

{

  "responseCode": "32",

  "responseText": "Invalid Request",

  "incommTxnId": null,

  "IMP-SourceTxnId": "551932ba-6af4-44f9-ab98-db5bc96e962b"

 }

}

我的POJO等级是

public class ResponseBaseParameters {

private String responseCode;

private String responseText;
private String incommTxnId;
@JsonProperty("IMP-SourceTxnId")
private String sourceTxnId;

public String getResponseCode() {
    return responseCode;
}

public void setResponseCode(String responseCode) {
    this.responseCode = responseCode;
}

public String getResponseText() {
    return responseText;
}

public void setResponseText(String responseText) {
    this.responseText = responseText;
}

public String getIncommTxnId() {
    return incommTxnId;
}

public void setIncommTxnId(String incommTxnId) {
    this.incommTxnId = incommTxnId;
}

public String getSourceTxnId() {
    return sourceTxnId;
}

public void setSourceTxnId(String sourceTxnId) {
    this.sourceTxnId = sourceTxnId;
}

}

请知道为何我的原因我收到这个错误。谢谢

Please any insight as to why i am getting this error. Thanks

推荐答案

REST API有很多实现，它们相互冲突。经过很长时间，我用这个配置解决了它：

There are many implementations of "REST API" and they conflict with each other. After a lot of time, I resolved it with this configuration:

import com.fasterxml.jackson.annotation.JsonProperty;
...
@JsonProperty("cep")
private String cep;

此包中的JsonProperty必须不是org.codehaus ...

Must have that JsonProperty with this package not org.codehaus...

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-client</artifactId>
    <version>1.19</version>
    <scope>test</scope>
</dependency>

总结：jersey客户端1，jackson json属性和删除所有其他jaxrc libs 。

In summary: jersey client 1, jackson json property and remove all others jaxrc libs.

Obs：我使用了jackson，因为已经提供了容器，但是，如果它适用于你，你可以测试另一种组合。

Obs:. I used jackson because the container already provided, but, if it works for you, you could test another combinations.
