问题描述

运行我的web应用程序时出现以下错误。我在配置hibernate&春天与右罐子。在经过了几个小时之后，我跨过了这个障碍之后，我在 hibernate datasource 中遇到了问题。会话工厂和dao bean在spring
中正确初始化，但是当我在dao中访问方法时出错...

以下是我的 application context.xml .. 

 < bean id =myDataSourceclass =org.apache.commons .dbcp.BasicDataSourcedestroy-method =close> 
< property name =driverClassNamevalue =com.mysql.jdbc.Driver/> 
< property name =urlvalue =jdbc：mysql：// localhost：3306 / test_amar/>

< property name =hibernateProperties> 
<道具> 
< prop key =dialect> org.hibernate.dialect.MySQLDialect< / prop>

我使用 spring3& hibernate4 即可。看起来我的数据源中存在配置错误。但我无法找到它。



从下面的服务器日志中，我看到dao&会话工厂bean正确实例化。

请协助..

解决方案

根据最新版本，不支持方法 getConnection（user，password），但hibernate不应该调用该方法。

你可以使用spring提供的 org.springframework.jdbc.datasource.DriverManagerDataSource 或 com.mysql.jdbc.jdbc2.optional.MysqlDataSource 从你的MySQL连接器包中获取。 （）


I get below error while running my web application. I had problems in configuring hibernate & spring with right jars. After i crossed that hurdle after working on it for hours, i am getting problem in hibernate datasource. The session factory and dao beans are getting initialized properly by springbut when i access method in dao i get error...

Below is my application context.xml..

   <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/test_amar"/>
    <property name="username" value="root"/>
    <property name="password" value=""/>
    <property name="initialSize" value="2"></property>
        <property name="maxActive" value="5"></property>
    <property name="validationQuery" value="SELECT 1"/>
  </bean>

  <!-- Hibernate Session Factory -->
  <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="packagesToScan">
      <array>
        <value>entities</value>
      </array>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.MySQLDialect</prop>
        </props>

    </property>
  </bean>

i use spring3 & hibernate4. It appears there is configuration error in my datasource. but i am not able to locate it.

From the server log below , i see that dao & session factory beans are instantiated properly. 

INFO:   Loading XML bean definitions from ServletContext resource [/WEB-INF/dispatcher-servlet.xml]

Kindly assist..

解决方案

Accoording to the latest version, the method getConnection(user, password) is not supported, but hibernate should not be calling that method.

You can use the spring provided org.springframework.jdbc.datasource.DriverManagerDataSource or the com.mysql.jdbc.jdbc2.optional.MysqlDataSource from your MySQL connector package. (http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html)
