@NotNull annotation not working as expected Java Jersey

Question

I have an endpoint implementation, that I am passing an object to in the parameter list. I am trying to verify that this object is not null, using the @NotNull annotation. <

Answer 1

If you have bean-validation dependency on classpath (org.glassfish.jersey.ext:jersey-bean-validation:2.22.2) it should be picked up by the framework and work out of the box.

Also make sure that your @NotNull annotation comes from javax.validation.constraints package
