带Hibernate映射的BeanCreationException（使用Spring和Maven）

Question

我试图正确地建立不同实体之间的关系。

看着代码，我认为一切都是好的和连贯的（我已经验证了属性的名称与在Hibernate映射配置文件中建立的名称相同），但是，好吧，它没有编译。所以很明显这是不可以的。显示的错误如下：

org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'org.springframework.dao.annotation.
PersistenceExceptionTranslationPostProcessor#0' defined in class path
resource [spring.cfg.xml]: Initialization of bean failed; nested 
exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'sessionFactory' defined in class path
resource [spring.cfg.xml]: Invocation of init method failed; nested
exception is org.hibernate.HibernateException: Unable to instantiate
default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]

<!-- Profiles. * The build is always executed by selecting at least two
    non-exclusive profiles. By default, such profiles are "dev" and "postgresql"
    (meaning "use PostgreSQL assuming a development environment"). * General
    profiles. There are two general (database-independent) profiles: "dev" and
    "prod". The former is used for development (including testing) and the latter
    is used for production (including testing). As shown below, two dataSources
    (databases schemas) are used in both profiles: one for running (dataSource)
    and another one for the Maven test fase (testDataSource). Note the Maven
    test fase is executed both with development and production profiles. * Database-specific
    profiles. There is a profile for each supported database. * Specific profiles
    can be defined to better adapt to a particular environment by overwriting/adding
    properties and/or including other chunks of valid XML. * Usage: + mvn <<goal>>
    => Execute <<goal>> with default profiles. + mvn -Pdev,<<database>> <<goal>
    => Execute <<goal>> with "dev" and <<database>> profiles. + mvn -Pprod,<<database>>
    <<goal>> => Execute <<goal>> with "prod" and <<database>> profiles. + Note
    that when using -P option all desired profiles must be specified (e.g. "-Pprod"
    with the intention to select "prod" and the default database profile is not
    correct; "-Pprod,<<database>>" must be used instead). * Examples: + mvn <<goal>>
    + mvn -Ppostgresql,prod <<goal>> + mvn -Ppostgresql,dev <<goal>> -->

任何Java专家都有能力看到这里发生的事情或给出任何线索？正如我所说的，我已经验证了名称属性，我没有看到任何错别字错误。

Answer 1

有时当您的类路径中没有javassist.jar时会出现此错误。就像你说的那样。确保您拥有类属性的所有getter和setter。
