Infinite Recursion with Jackson JSON and Hibernate JPA issue

Question

When trying to convert a JPA object that has a bi-directional association into JSON, I keep getting

org.codehaus.jackson.map.JsonMappingException: Infinite          


        

Answer 1

If you cannot ignore the property, try modifying the visibility of the field. In our case, we had old code still submitting entities with the relationship, so in my case, this was the fix:

    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private Trainee trainee;
