我必须在我的应用程序中管理多个数据库我的配置文件应用程序是

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">

    <!-- Scans the classpath of this application for @Components to deploy as beans -->
    <context:component-scan base-package="fr.tessa.jee.webmanager" />

    <!-- Configures the @Controller programming model -->
    <mvc:annotation-driven />

    <!-- misc -->
    <bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
        <property name="suffix" value=".jsp" />
    </bean>

    <!-- Configure the multipart resolver -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- one of the properties available; the maximum file size in bytes -->
        <property name="maxUploadSize" value="1000000" />
    </bean>

    <!-- Configures Hibernate - Database Config -->
    <import resource="dbconfig/db-config.xml" /> 
    <import resource="dbconfig/validationdb-config.xml" />

</beans>

我的“db-config.xml”是

<?xml version="1.0" encoding="UTF-8"?>

我在包 fr.tessa.jee.webmanager.validation.model 中有用户类，在包 fr.tessa.jee.webmanager.model 中有客户端；问题是，当我尝试获取用户列表时出现错误，例如没有为当前线程找到会话但是对于客户端列表很好，当我开始在 app-config 中导入“validationdb-config.xml”时

<import resource="dbconfig/validationdb-config.xml" />
<import resource="dbconfig/db-config.xml" />

当我尝试获取客户列表时出现错误

我的配置有什么问题？请帮忙 ：（

我找到了问题，问题出在我的服务中的事务方法中，我必须像这样指定事务管理器的 ID

@Transactional(readOnly = true, value="teoTransactionManager")
public List<Client> getClientList() {
    return clientDAO.getClients();
}

当我开始时，我只输入了@Transactional(readOnly = true)
