java - hibernate h2 not generating relations -

i'm trying generate hibernate mapping h2 database. have 2 tables test, called users , users_groups. like:

users table:     user_id           integer     pk     login             varchar     password          varchar     user_group_id     integer     fk  users_groups     user_group_id     integer     pk     name              varchar 

and problem hibernate generate entities that:

@entity public class users { private int userid; private int usergroupid;  @id @column(name = "user_id", nullable = false) public int getuserid() {     return userid; }  public void setuserid(int userid) {     this.userid = userid; }   @basic @column(name = "user_group_id", nullable = false) public int getusergroupid() {     return usergroupid; }  public void setusergroupid(int usergroupid) {     this.usergroupid = usergroupid; }  @entity @table(name = "users_groups", schema = "public", catalog = "database") public class usersgroups { private int usergroupid;  @id @column(name = "user_group_id", nullable = false) public int getusergroupid() {     return usergroupid; }  public void setusergroupid(int usergroupid) {     this.usergroupid = usergroupid; } 

so no relation annotations generated, @onetomany or @manytomany etc. doing wrong? help. p.s. want generate mapping users class field of usergroup type

if classes auto generated check relation in database between 2 tables , make sure choose right schema mapping wrong example :-

1-the auto generated classes mapping missing columns, class user doesn't contain password , login columns , class usersgroups doesn't contain name column.

2- class user doesn't have @table annotation

they should :-

class usergroups

@entity @table(name = "users_groups", schema = "public", catalog = "database") public class usersgroups implements java.io.serializable {    private int usergroupid;    private string name;    private set<users> users = new hashset<users>(0);     public usersgroups() {     }     @id    @generatedvalue(strategy = identity) //this make id auto increment    @column(name = "user_group_id", nullable = false)    public int getusergroupid() {        return usergroupid;    }     public void setusergroupid(int usergroupid) {        this.usergroupid = usergroupid;    }     // if name column not unique / nullable remove values annotation     @column(name = "name", unique = true, nullable = false, length = 10)     public string getname() {        return this.name;     }     public void setname(string name) {     this.name= name;     }    @onetomany(fetch = fetchtype.eager, mappedby = "users_groups")    public set<users> getusers() {        return this.users;    }     public void setusers(set<users> users) {        this.users= users;    }    } 

class users

@entity @table(name = "users", schema ="public" , catalog ="database") public class users implements java.io.serializable {      private integer userid;     private usersgroups usersgroups;     private string password;     private string login;      public users() {     }       @id     @generatedvalue(strategy = identity)     @column(name = "user_id", unique = true, nullable = false)     public integer getuserid() {         return this.userid;     }      public void setuserid(integer userid) {         this.userid = userid;     }          @manytoone(fetch = fetchtype.eager)         @joincolumn(name = "user_group_id", nullable = false)         public usersgroups getusersgroups() {             return this.usersgroups;         }          public void setusersgroups(usersgroups usersgroups) {             this.usersgroups = usersgroups;         }          @column(name = "password",length = 10)         public string getpassword() {             return this.password;         }          public void setpassword(string password) {             this.password = password;         }          @column(name = "login",length = 10)         public string getlogin() {             return this.login;         }          public void setlogin(string login) {             this.login = login;         }      }
