Question

我尝试使用c3p0连接池管理在tomcat 7.0.57上运行hibernate应用程序。由于NoSuchMethodError，无法构建sessionFactory。

这是我的pom.xml：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.1.0.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-c3p0</artifactId>
    <version>5.1.0.Final</version>
</dependency>   
<dependency>
    <groupId>com.mchange</groupId>
    <artifactId>c3p0</artifactId>
    <version>0.9.5.2</version>
</dependency>

我的hibernate.cfg.xml：

<property name="hibernate.connection.provider_class">org.hibernate.c3p0.internal.C3P0ConnectionProvider</property>
<property name="hibernate.c3p0.min_size">10</property>
<property name="hibernate.c3p0.max_size">20</property>
<property name="hibernate.c3p0.acquire_increment">1</property>
<property name="hibernate.c3p0.idle_test_period">300</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.timeout">180</property>

当我重新启动Tomcat时，我得到了这个例外：

java.lang.NoSuchMethodError: org.hibernate.engine.jdbc.connections.internal.ConnectionProviderInitiator.extractIsolation(Ljava/util/Map;)Ljava/lang/Integer;

此处抛出异常（buildSessionFactory）：

public class HibernateUtil {

private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;

public static SessionFactory createSessionFactory() {
    Configuration configuration = new Configuration();

    try {
        configuration.configure();
    } catch (HibernateException e) {
        configuration.configure("/META-INF/hibernate.cfg.xml");
    }

    serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
            configuration.getProperties()).build();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);

    return sessionFactory;
}

Answer 1

就像kem已经问到的那样，仍然有一个早期的hibernate版本（4.3.6。）部署到tomcat容器，导致了这个异常。此版本在同一个webapp中的另一个jar中使用。

将此jar更新为同一版本解决了这个问题。

NoSuchMethodError：使用Hibernate 5.1.0和c3p0
