Hibernate 4: ViolatedConstraintNameExtracter异常
Hibernate 4: ViolatedConstraintNameExtracter异常
提问于 2014-02-02 19:15:36
我正在尝试在Maven项目中设置Hibernate 4。不管用，快把我逼疯了。
我明白这一例外：
java.lang.NoClassDefFoundError: org/hibernate/exception/ViolatedConstraintNameExtracter这些是在pom.xml文件中声明的依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.1.Final</version>
</dependency>
<dependency>
<groupId>org.xerial</groupId>
<artifactId>sqlite-jdbc</artifactId>
<version>3.7.2</version>
</dependency>
<dependency>
<groupId>org.hibernate.dialect</groupId>
<artifactId>sqlite-dialect</artifactId>
<version>0.1.0</version>
<scope>provided</scope>
</dependency>这是我的Hibernate配置文件：
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">org.sqlite.JDBC</property>
<property name="hibernate.connection.password"></property>
<property name="hibernate.connection.url">jdbc:sqlite:test.db</property>
<property name="hibernate.connection.username"></property>
<property name="hibernate.dialect">org.hibernate.dialect.SQLiteDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
</session-factory>
</hibernate-configuration>这就是“破烂”代码：
Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);我只有一个名为"User“的测试模型，并使用Hibernate注释进行修饰。
你能帮我做这个吗？干杯。

您使用的方言与Hibernate 4不兼容。请参阅https://github.com/gwenn/sqlite-dialect/blob/master/src/main/java/org/hibernate/dialect/SQLiteDialect.java：它使用org.hibernate.exception.ViolatedConstraintNameExtracter，它已在Hibernate 4中移动到org.hibernate.exception.spi.ViolatedConstraintNameExtracter。

在Hibernate 4.X中，类ViolatedConstraintNameExtracter从包org.hibernate.exception移到org.hibernate.exception.spi (JavaDoc)。错误消息声明没有找到org/hibernate/exception/ViolatedConstraintNameExtracter。
这意味着运行时类路径中至少有一个库请求旧的3.xHibernate类。您应该使用Maven 依赖插件或Eclipse检查依赖项。
