我在此添加了web.xml的源代码
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name>ussd</display-name> <servlet> <servlet-name>init</servlet-name> <jsp-file>/init.jsp</jsp-file> <load-on-startup>1</load-on-startup> </servlet> <context-param> <param-name>javax.ws.rs.core.Application</param-name> <param-value>com.dialog.mife.ussd.api.USSDApplication</param-value> </context-param> <context-param> <param-name>resteasy.providers</param-name> <param-value>com.dialog.mife.ussd.exception.NotFoundException</param-value> </context-param> <context-param> <param-name>resteasy.servlet.mapping.prefix</param-name> <param-value>/</param-value> </context-param> <listener> <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class> </listener> <servlet> <servlet-name>Resteasy</servlet-name> <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class> </servlet> <servlet> <servlet-name>ServletAdaptor</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Resteasy</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>ServletAdaptor</servlet-name> <url-pattern>/webresources/*</url-pattern> </servlet-mapping> </web-app>
Hibernate.cfg.xml。我的Web服务项目与Jersey + Hibernate一起使用。
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.bytecode.use_reflection_optimizer">false</property> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.password">xxx</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/USSD</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <property name="show_sql">true</property> <property name="hbm2ddl.auto">update</property> <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> <property name="connection.pool_size">1</property> <property name="hibernate.connection.autocommit">true</property> <mapping class="com.xxx.xxx.xxx.xxx.Application" /> </session-factory> </hibernate-configuration>
这是HibernateUtil类
public class HibernateUtil { private static final SessionFactory sessionFactory; static { try { sessionFactory = new Configuration().configure().buildSessionFactory(); } catch (Exception ex) { ex.printStackTrace(); throw new ExceptionInInitializerError(ex); } }
这是我添加了Hibernate最新的jar文件的错误。[ hibernate-core-4.3.7.Final.jar ]

请帮我解决这个问题谢谢
初始化SessionFactory失败时可能会发生这种错误。您已经提到您正在使用hibernate- core-4.3.7。初始化的SessionFactory方式不适用于该版本。使用 Hibernate 3.x版或更改初始化方式SessionFactory。以下是在中建立会话工厂的正确方法Hibernate 4.x +。
SessionFactory
hibernate- core-4.3.7
Hibernate 4.x +
Configuration configuration = new Configuration().configure(); StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder(). applySettings(configuration.getProperties()); SessionFactory factory = configuration.buildSessionFactory(builder.build());
