我正在尝试正确建立不同实体之间的关系。

查看代码我认为一切正常且连贯（我已验证属性与 Hibernate 映射配置文件中建立的名称相同），但是，它无法编译。所以很明显这是不行的。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]

pom.xml 文件如下

<!-- 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 专家都能够看到这里发生了什么或提供任何线索？正如我所说，我已经验证了名称属性，并且没有看到任何拼写错误。

妈的！我觉得自己真的很愚蠢。我确信我已经验证了该实例的所有属性。

该错误是由于其中一个名为“Comment”的类中的错误引起的。我已经阅读了堆栈跟踪中的最新错误，但如果我继续阅读堆栈跟踪，我可以找到以下内容：

Caused by: org.hibernate.PropertyNotFoundException: field [user] not found on org.snippr.business.entities.Comment

类评论中没有属性“用户”。映射和类 Comment 之间存在不一致。映射引用属性 user，但 Comment 有属性 Set users。班级不正确（我把关系 1-N 弄错了）。

有时，当您的类路径中没有 javassist.jar 时会发生此错误。如我所见，您已宣布。确保您拥有类属性的所有 getter 和 setter。
