使用Jadiru Joda/Hibernate持久用户类型时的AbstractMethodError

Question

我已经在我的用户的MySQL TIMESTAMP类型数据库中引入了一个"创建"列.我正在尝试使用Jadiru的UserType Hibernate映射器将其映射到Joda LocalDateTime.我使用的是UserType类的v2.0,我尝试过使用v 3.6.0和3.6.7的Hibernate.我正在使用JDK 1.6.此数据访问层正用作Spring 3 Web应用程序的一部分.

这是我的持久性对象的相关位 -

@Column(name = "created")
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime") 
private LocalDateTime created;

没有什么太复杂,但每当我的UserDAO试图查询表时,我得到以下异常 -

java.lang.AbstractMethodError: org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime.nullSafeGet(Ljava/sql/ResultSet;[Ljava/lang/String;Ljava/lang/Object;)Ljava/lang/Object;

我已经尝试将所有注释放在方法而不是字段上,但同样的问题.

我也尝试将不同的列类型(如DATE)映射到LocalDate,将TIME映射到LocalTIME,但每个列类型都会产生类似的错误.

我尝试的另一件事是使用条件查询而不是基于模板的查询.这并没有影响到这个问题.

我已经检查了重复库的类路径,但似乎没有.

我的设置显然有些问题,因为UserType文档说这应该可行.没有谷歌任何人都会遇到这个错误.请有人指出我正确的方向吗？

谢谢,

Answer 1

不是解决方案而是指针/提示:nullSafeGet看起来奇怪的签名.它应该是

public T nullSafeGet(ResultSet resultSet,
                 String[] strings,
                 org.hibernate.engine.spi.SessionImplementor session,
                 Object object)
          throws SQLException

但是hibernate在nullSafeGet没有SessionImplementor参数的情况下调用a .所以实际的CustomType类可能会定义一个抽象nullSafeGet方法,它不是在实际的实现者中实现的PersistentLocalDateTime(它只是实现了一个具有不同参数的方法)

也许您的joda和hibernate版本不兼容.我再次调查那个方向.
