Import Entities from DB with ManyToMany relationships doesn't manage mappedBy ----------------------------------------------------------------------------- Key: JBIDE-26458 URL: https://issues.redhat.com/browse/JBIDE-26458 Project: Tools (JBoss Tools) Issue Type: Bug Components: hibernate Affects Versions: 4.6.0.Final Environment: Eclipse: Oxygen.3a Release (4.7.3a) Build id: 20180405-1200 DBMS: Sql Anywhere 17.0.9.4857 Annotations jdk 1.5+ Hibernate Version 5.2 Reporter: Matteo Barrese Assignee: Koen Aers Priority: Major Fix For: 4.17.0.AM1 Import from entities tool does not correctly handle the bidirectional ManyToMany relationships because in some cases it does not define mappedBy on one side. example: {code:java} public class SecGroup implements java.io.Serializable { .... @ManyToMany(fetch = FetchType.LAZY) @JoinTable(name = "SecGroupUser", schema = "dbm", joinColumns = { @JoinColumn(name = "GroupId", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "UserId", nullable = false, updatable = false) }) public Set<SsUsers> getSsUserses() { return this.ssUserses; } .... } public class SsUsers implements java.io.Serializable { ... @ManyToMany(fetch = FetchType.LAZY) @JoinTable(name = "SecGroupUser", schema = "dbm", joinColumns = { @JoinColumn(name = "UserId", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "GroupId", nullable = false, updatable = false) }) public Set<SecGroup> getSecGroups() { return this.secGroups; } ... } {code} It must be for example {code:java} public class SecGroup implements java.io.Serializable { .... @ManyToMany(fetch = FetchType.LAZY, mappedBy = "secGroups") public Set<SsUsers> getSsUserses() { return this.ssUserses; } .... } public class SsUsers implements java.io.Serializable { ... @ManyToMany(fetch = FetchType.LAZY) @JoinTable(name = "SecGroupUser", schema = "dbm", joinColumns = { @JoinColumn(name = "UserId", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "GroupId", nullable = false, updatable = false) }) public Set<SecGroup> getSecGroups() { return this.secGroups; } ... } {code}
