Question

我尝试将BoneCP与我的JSF-Spring-Hibernate组合一起使用，并在他们的网站上进行BoneCP配置。

我使用Intellij作为IDE，我直接将框架支持添加到项目中，但是BoneCP及其所需的库是从maven中获取的。

这是我的简单spring-config.xml

<context:component-scan base-package="user" />

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <!-- Don't forget to list all your entity classes here -->
    <property name="annotatedClasses">
        <list>
            <value>user.model.User</value>
        </list>
    </property>

    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
        </props>
    </property>
</bean>

<!-- Spring bean configuration. Tell Spring to bounce off BoneCP -->
<bean id="dataSource"
      class="org.springframework.jdbc.datasource.LazyConnectionDataSourceProxy">
    <property name="targetDataSource">
        <ref local="mainDataSource" />
    </property>
</bean>

<!-- BoneCP configuration -->
<bean id="mainDataSource" class="com.jolbox.bonecp.BoneCPDataSource" destroy-method="close">
    <property name="driverClass" value="com.mysql.jdbc.Driver" />
    <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ch?characterEncoding=utf8" />
    <property name="username" value="root"/>
    <property name="password" value="1234"/>
    <property name="maxConnectionsPerPartition" value="60"/>
    <property name="minConnectionsPerPartition" value="20"/>
    <property name="partitionCount" value="3"/>
    <property name="acquireIncrement" value="10"/>
    <property name="statementsCacheSize" value="50"/>
    <property name="releaseHelperThreads" value="3"/>
</bean>

<!-- Enable the configuration of transactional behavior based on annotations -->
<tx:annotation-driven transaction-manager="txManager"/>

<!-- Transaction Manager is defined -->
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

当我在Tomcat 7上运行项目时，它给了我这些错误：

找不到BoneCP类。我该如何解决？我正在使用bonecp-provider 0.8.0-alpha1 hibernate 4 spring 3 jsf 2

Answer 1

您不仅需要-provider，还需要bonecp-version.jar（例如this one）。我不知道你在哪里获得.8 alpha版本，但是那里也必须有一个类似的jar。

编辑：错过了你使用Maven。然后只需复制您的依赖关系定义

<dependency>
  <groupId>com.jolbox</groupId>
  <artifactId>bonecp-provider</artifactId>
  <version>0.8.0-alpha1</version>
</dependency>

进入

<dependency>
  <groupId>com.jolbox</groupId>
  <artifactId>bonecp</artifactId>
  <version>0.8.0-alpha1</version>
</dependency>

Answer 2

com.jolbox.bonecp.BoneCPDataSource位于核心jar文件中，因此您根本不需要-provider jar。

还要使用-rc1而不是-alpha1。

使用JSF Spring Hibernate配置的BoneCP
