当我尝试调用 save 方法时，我的代码中出现此错误，当我在 JBoss 服务器上时，此方法工作正常，现在我转到 tomcat 服务器 7

我的 Bean 类是
@Entity
@Table(name = "company_studies", catalog = "studybuddyDB")
public class CompanyStudies implements java.io.Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
// Fields
private Integer studyId = 0;
private CompanyDetail companyDetail;
private int isActive;
/** default constructor */
public CompanyStudies() {
}
/** full constructor */
public CompanyStudies(CompanyDetail companyDetail,int isActive) {
this.setCompanyDetail(companyDetail);
this.setIsActive(isActive);*/
this.companyDetail = companyDetail;
this.isActive = isActive;
}
// Property accessors
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "study_id", unique = true, nullable = false )
public Integer getStudyId() {
return studyId;
}
public void setStudyId(Integer studyId) {
this.studyId = studyId;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "company_detail_id")
public CompanyDetail getCompanyDetail() {
return companyDetail;
}
public void setCompanyDetail(CompanyDetail companyDetail) {
this.companyDetail = companyDetail;
}
@Id
@Column(name = "isActive", nullable = false)
public int getIsActive() {
return isActive;
}
public void setIsActive(int isActive) {
this.isActive = isActive;
}
}
请帮我解决这个问题
我也遇到过同样的错误
经过一番研究后，我得出的结论是，这取决于两件事。
What DB you are using plus
What @GenericGenerator - what strategy you are using.
我能够通过以下配置解决问题。
DB - MySQL
Changed strategy to increment from native
我的代码如下所示：
@ElementCollection
@JoinTable(name="USERS_ADDRESSES",
joinColumns=@JoinColumn(name="USER_ID"))
@GenericGenerator(name="hilogen", strategy="increment")
@CollectionId(columns= {@Column(name="ADDR_ID")},
generator="hilogen", type=@Type(type="long"))
private List addressList = new ArrayList();
希望这有帮助。
谢谢，萨加尔·维亚斯
