<Context>
<Resource name="jdbc/sotpas"
auth="Container"
type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="root" password="123456"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://127.0.0.1:3306 liuupeng?characterEncoding=utf8"/>
</Context>

Answer 1

url="jdbc:mysql://127.0.0.1:3306/liuupeng?characterEncoding=utf8"

url 后面的数据库和端口号之间好像有"/"吧。

Answer 2

<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/log</property> （端口和具体的数据库之间有个/的）
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">123</property>
<mapping resource="cn/bsw3/www/entity/Customer.hbm.xml" />
