java - Hibernate does not accept ManyToOne as Id -

hibernate not agree construction. missing anything? error throws me:

org.hibernate.mappingexception: unable find column logical name: version_id in processes

any suggestions on how fix while keeping composite key structure?

datamodel

version has many actions

version has many processes;

public class version {     @id     @column(name = "id")     public int id; } 

action has 1 process

action has 1 version

public class action {     // action has composite key (id , version id)      @id     @column(name = "id")     public int id;      @id     @manytoone     @joincolumn(name = "version_id")     public version version;      @manytoone     @joincolumns({         @joincolumn(name = "process_id", referencedcolumnname = "id"),         @joincolumn(name = "version_id", referencedcolumnname = "version_id")     })     public process process; } 

process has many actions

process has 1 version

    public class process {     // process has composite key (id , version id)      @id     @column(name = "id")     public int id;      @id     @manytoone     @joincolumn(name = "version_id")     public version version;      @onetomany(fetch = fetchtype.lazy, mappedby = "process", targetentity = action.class)     public list<action> actions= new arraylist<action>(); }

you have 2 columns named version_id in action class. try renaming second version_id process_version_id:

public class action {     // action has composite key (id , version id)      @id     @column(name = "id")     public int id;      @id     @manytoone     @joincolumn(name = "version_id")     public version version;      @manytoone     @joincolumns({         @joincolumn(name = "process_id", referencedcolumnname = "id"),         @joincolumn(name = "process_version_id", referencedcolumnname = "version_id")     })     public process process; }
