Question

我的mysql-connector jar在：

1。）Tomcat Server lib

2。）构建路径作为外部JAR。 *从Maven依赖项中删除，尽管它仍然存在相同的错误。

jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql//localhost:3306/test
jdbc.username=root
jdbc.password=****

web.xml 使用代码段添加它：

<resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/test</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

我完整的 servlet-context.xml

<context:annotation-config />
<context:component-scan base-package="org.springsecudev.controller" />
<context:component-scan base-package="org.springsecudev.model" />
<context:component-scan base-package="org.springsecudev.service" />
<context:component-scan base-package="org.springsecudev.dao" />

    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"

<beans:bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
    destroy-method="close" p:driverClassName="${jdbc.driverClassName}"
    p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}">
</beans:bean>

<beans:bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <beans:property name="dataSource" ref="dataSource"/>
    <beans:property name="configLocation">
        <beans:value>classpath:hibernate.cfg.xml</beans:value>
    </beans:property>
    <beans:property name="configurationClass">

    <beans:property name="hibernateProperties">

            <beans:prop key="hibernate.show_sql">true</beans:prop>
        </beans:props>
    </beans:property>
</beans:bean>

<beans:bean id="transactionManager" 
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">

        <beans:property name="useExpiresHeader" value="true"/>
        <beans:property name="useCacheControlHeader" value="true"/>
        <beans:property name="useCacheControlNoStore" value="true"/>
    </beans:bean>
</interceptors>

<beans:bean id="encoder"  
class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
    <beans:constructor-arg value="12"></beans:constructor-arg>
</beans:bean>

我还在META-INF中添加了 context.xml ，以确保我也尝试了这个

<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Resource  name="jdbc/test" 
        username="root" 
        password="root" 
        driverClassName="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/test"
        auth="Container" 
        type="javax.sql.DataSource"
        maxActive="100" 
        maxIdle="30" 
        maxWait="10000"
        initialSize="1"/>

但仍然没有运气，它也有同样的错误：

[缩短] 引起：java.sql.SQLException：没有合适的驱动程序 在org.apache.commons.dbcp2.BasicDataSource.createConnectionFactory（BasicDataSource.java:2151） ......还有40多个

我一直试图找出可能存在的问题，其中我在构建路径和服务器库中复制了jar。

Answer 1

您似乎错过了文件jdbc.properties中冒号的数据库网址。

jdbc:mysql//localhost:3306/test

我认为应该是

jdbc:mysql://localhost:3306/test

Spring + Hibernate + Maven：jCannot为连接URL'jdbc：mysql // localhost：3306 / test'创建类'com.mysql.jdbc.Driver'的JDBC驱动程序
