Java – Jackson @ jsonproperty is invalid if the property name is not equal to the field name

I have the following JSON

{
  "kNown-name": "Zevs","approximate-age": 320
}

And binding classes

public class GodBinding {

  @JsonProperty("kNown-name")
  public String name;

  @JsonProperty("approximate-age")
  public int age;

  // constructors
  // getters & setters
}

And followng Maven dependence 2.23 2 2.5. four

<dependencies>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-servlet</artifactId>
        <version>${jersey.version}</version>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-json-provider</artifactId>
        <version>${jackson.version}</version>
    </dependency>
 </dependencies>

If I publish such a JSON, then I have a null unexpected result

GodBinding [name=null,age=0]

If I use @ jsonproperty without a name and send JSON, where the property name is equal to the field name

{
  "name": "Zevs","age": 320
}

Then it works normally

GodBinding [name=Zevs,age=320]

If anyone knows, how does @ jsonproperty ("name") work on fields?

Solution

You should add it to your POM

<dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.4.4</version>
</dependency>
