@JsonProperty没有按预期工作

Question

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"])

The response parameter is

{

  "responseBaseParameters":  

{

  "responseCode": "32",

  "responseText": "Invalid Request",

  "incommTxnId": null,

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

 }

}

and my POJO class is

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;
}

}

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

Answer 1

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;

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>

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

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