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

Be sure you use com.fasterxml.jackson everywhere. I spent much time to find it out.

  2.9.2




  com.fasterxml.jackson.core
    jackson-annotations
    ${fasterxml.jackson.version}




  com.fasterxml.jackson.core
    jackson-databind
    ${fasterxml.jackson.version}

Then use @JsonManagedReference and @JsonBackReference.

Finally, you can serialize your model to JSON:

import com.fasterxml.jackson.databind.ObjectMapper;

ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(model);
