My Custom DTO class is as follows :
public class TestDto1 {
private String key;
private String val;
@AssertTrue
private boolean isValid() {
return key !=null || val !=null;
}public class TestDto1 {
private String key;
private String val;
@AssertTrue
private boolean isValid() {
return key !=null || val !=null;
}
My Parent DTO class :
public class TestDto {
private String id;
@Valid
private TestDto1 tes;
public TestDto1 getTes() {
return tes;
}
public void setTes(TestDto1 tes) {
this.tes = tes;
}
public String getId() {
return id;
While running the app and hitting api with following JSON getting following error:
{
"id":"1234",
"tes":{
}
}
JSR-303 validated property 'tes.valid' does not have a corresponding accessor for Spring data binding - check your DataBinder's configuration (bean property versus direct field access)] with root cause
org.springframework.beans.NotReadablePropertyException: Invalid property 'tes.valid' of bean class [com.example.thirdparty.controller.TestDto]: Bean property 'tes.valid' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
Please let me know what needs to be done here
This is not a field that gets validated but a method which is kind of read as a virtual field from that method.
I think the method has to be declared as public to become accessible for validation
@AssertTrue
public boolean isValid() {
return key !=null || val !=null;
}
