No suitable driver found for jdbc:mysql://localhost:3306/db_database10 (1)LZ你的数据库db_database10有没有创建? (2)MYSQL JAR包有没有添加? (3)LZ你的数据库有没有启动?
你说的3条都做了,我在这边写了一个简单的jsp连接数据库测试了一下,发现能连得上,然而Hibernate就连不上了是不是缺少什么

sessionFactory是自动生成的,应该不会出问题吧....... jar包应该没问题吧,直接连接不用hibernate是能连得上的

配置如下 <hibernate-configuration> <session-factory> <!-- 数据库驱动 --> <property name="connect.driver_class"> com.mysql.jdbc.Driver </property> <!-- 数据库连接的URL --> <property name="connection.url"> jdbc:mysql://localhost:3306/db_database10 </property> <!-- 数据库连接用户名 --> <property name="connection.username">root</property> <!-- 数据库连接密码 --> <property name="connection.password">123321</property> <!-- Hibernate方言 --> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <!-- 打印sql语句 --> <property name="show_sql">true</property> <!-- 映射文件 --> <mapping resource="com/xdc/Product/Product.hbm.xml" /> </session-factory> </hibernate-configuration>

好像你MySQL的jar包版本的问题。 你MySQL用的什么版本的,看看你的方言设置的正确么?

你好,我发现了两个问题。第一:你的数据库连接不上,原因可能是你的数据库连接串有问题,或者你没有把数据库驱动的包导入。 第二:你的sessionFactory为null,原因可能是你的程序写的有问题,取得sessionFactory的那个类写的有问题。
