behavior - Hibernate ManyToOne and OneToMany -


i have relationship mapped example.

@entity @table(name = "shop") public class shop implements serializable {      ...      @onetomany(mappedby = "shop", fetch=fetchtype.lazy)     private set<event> events;      ...  } 

@entity @table(name = "event") public class event implements serializable {      ...      @manytoone(fetch = fetchtype.lazy)     @joincolumn(name = "shop_id", nullable = false)     private shop shop;      ...  } 

when local getevent() called loaded in colletion 1 list few events, each event have inside shop might have inside event , successively.. ok?. can problem responsing json structure?

i had problem during serialization json

...     @ org.codehaus.jackson.map.ser.std.collectionserializer.serializecontents(collectionserializer.java:72)     @ org.codehaus.jackson.map.ser.std.collectionserializer.serializecontents(collectionserializer.java:23)     @ org.codehaus.jackson.map.ser.std.asarrayserializerbase.serialize(asarrayserializerbase.java:86)     @ org.codehaus.jackson.map.ser.beanpropertywriter.serializeasfield(beanpropertywriter.java:446)     @ org.codehaus.jackson.map.ser.std.beanserializerbase.serializefields(beanserializerbase.java:150)     @ org.codehaus.jackson.map.ser.beanserializer.serialize(beanserializer.java:112)     @ org.codehaus.jackson.map.ser.beanpropertywriter.serializeasfield(beanpropertywriter.java:446)     @ org.codehaus.jackson.map.ser.std.beanserializerbase.serializefields(beanserializerbase.java:150)     @ org.codehaus.jackson.map.ser.beanserializer.serialize(beanserializer.java:112)  ... 

to solve used @jsonignore annotation in 1 property:

@entity @table(name = "shop") public class shop implements serializable {      ...      @jsonignore     @onetomany(mappedby = "shop", fetch=fetchtype.lazy)     private set<event> events;      ...   } 

i hope information helpful. can't add comments yet.
