Question

我一直在从spring（2.5.5到4.0.2.RELEASE）和Hibernate（3.2.6到3.6.9）迁移我的应用程序。从Spring ORM JPA迁移我遇到了这个问题只是想让自己正确的是我的方式是对的，或者版本是所有这个问题的问题。

多个持续加载问题


Error creating bean with name 'something' defined in class path resource [spring/test-persistenceContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Conflicting persistence unit definitions for name

我通过

解决了这个问题

我删除了＆＃34; persistenceUnitName＆＃34;在test-persistenceContext.xml中为bean类＆＃34; org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean＆＃34;定义。我已经制作了＆＃34; persistenceUnitManager＆＃34;获取＆＃34; DefaultPersistenceUnitManager＆＃34;的属性通过使用ref和＆＃34; mergepersistenceUnitPostProcessor类＆＃34;其中包含PersistenceUnitPostProcessor接口。

然后它在那里顺利。但它给我构建实体时出错。

它一直在说复合ID已定义哪些不应该使用@Id，其中在实体类中使用@EmbededId和在密钥/ Id类中定义@ Id＆＃39;通常使用getId（）来获取相应的id。我从ID / Entity类中删除了所有@Id。
@ManyToOne()关系joincolumns无法识别我删除了@joincolumns annot以解决问题。

现在我完全陷入了以下错误


Error creating bean with name 'something' defined in class path resource [spring/test-persistenceContext.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: Foreign key (column names[1,2,3,4]) must have same number of columns as the referenced primary key (column names [1,2,4]).

不知道我已经修好了一个，但它继续出现像这个问题。如果您需要移动堆栈跟踪详细信息，请告诉我。

public class AccountEntityKey extends AbstractEntityKey {
 private String accountId;
}

@MappedSuperclass
@XmlAccessorType(XmlAccessType.PROPERTY)
public abstract class AbstractEntityKey implements EntityKey {

    private String status;
}

public class Account extends AbstractAccount {
@Transient
    private String accountId;

    @Transient
    private String status;

  @Override
    @EmbeddedId
    @AttributeOverrides( {
            @AttributeOverride(name = "accountId", column = @Column(name = "ACCT_ID", unique = false, nullable = false, insertable = true, updatable = false, length = 32)),
            @AttributeOverride(name = "status", column = @Column(name = "ACCT_STA_TYP", unique = false, nullable = false, insertable = true, updatable = false, length = 10)) })

    public AccountEntityKey getId() {
        return (id != null) ? (AccountEntityKey) super.getId() : new          AccountEntityKey(accountId,
                status);}
}

    public class AccountParty {

      /**
         * @return the account
         * (cascade = {}, fetch = FetchType.LAZY)    
         * @JoinColumns( {
                @JoinColumn(name = "ACCT_ID", unique = false, nullable = false, insertable      = false, updatable = false),
                @JoinColumn(name = "ACCT_STA_TYP", unique = false, nullable = false, insertable = false, updatable = false) })
         */
        @ManyToOne
        public Account getAccount() {
            return account;
        }

}
