Using Spring codegen on a schema with a discriminator property populates the @JsonTypeInfo annotation with the Discriminator class represented as a string, instead of the propertyName itself.
For example, this schema:
Example:
type: object
required:
- baseType
discriminator:
propertyName: baseType
properties:
baseType:
type: string
otherProp:
type: string
will generate this class:
/**
* Example
*/

@javax.annotation.Generated(value = "io.swagger.codegen.languages.java.SpringCodegen", date = "2018-06-18T16:55:52.608-04:00[America/New_York]")
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "Discriminator{propertyName='baseType', mapping=null}", visible = true )
@JsonSubTypes({
})
public class Example {
@JsonProperty("baseType")
private String baseType = null;
@JsonProperty("otherProp")
private String otherProp = null;
public Example baseType(String baseType) {
this.baseType = baseType;
return this;
}
/**
* Get baseType
* @return baseType
**/
@ApiModelProperty(required = true, value = "")
@NotNull
public String getBaseType() {
return baseType;
}
public void setBaseType(String baseType) {
this.baseType = baseType;
}
public Example otherProp(String otherProp) {
this.otherProp = otherProp;
return this;
}
/**
* Get otherProp
* @return otherProp
**/
@ApiModelProperty(value = "")
public String getOtherProp() {
return otherProp;
}
public void setOtherProp(String otherProp) {
this.otherProp = otherProp;
}
@Override
public boolean equals(java.lang.Object o) {
if (this == o) {
return true;
}
if (o == null || getClass() != o.getClass()) {
return false;
}
Example example = (Example) o;
return Objects.equals(this.baseType, example.baseType) &&
Objects.equals(this.otherProp, example.otherProp);
}
@Override
public int hashCode() {
return Objects.hash(baseType, otherProp);
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("class Example {\n");
sb.append(" baseType: ").append(toIndentedString(baseType)).append("\n");
sb.append(" otherProp: ").append(toIndentedString(otherProp)).append("\n");
sb.append("}");
return sb.toString();
}
/**
* Convert the given object to string with each line indented by 4 spaces
* (except the first line).
*/
private String toIndentedString(java.lang.Object o) {
if (o == null) {
return "null";
}
return o.toString().replace("\n", "\n ");
}
}
The point of interest here is with the line:
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "Discriminator{propertyName='baseType', mapping=null}", visible = true )
which should read:
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "baseType", visible = true )
