Question

我正在使用Spring MVC + Hibernate + Security示例，在这个项目中，我试图在同一个application-context.xml中使用hibernate4.LocalSessionFactoryBean配置两个数据源？

我尝试如下，但导致以下错误

<bean id="test1sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="test1dataSource" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show.sql">${hibernate.show}</prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
            </list>
        </property>
</bean>


<bean id="test2sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="test2dataSource" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show.sql">${hibernate.show}</prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
            </list>
        </property>
</bean>

配置的数据源：

<bean id="test1dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
</bean>

    <bean id="test2dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${jdbc.driverClassName}" />
            <property name="url" value="${jdbc.url}" />
            <property name="username" value="${jdbc.username}" />
            <property name="password" value="${jdbc.password}" />
    </bean>

如何解决此错误？

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'test1sessionFactory' defined in class path resource [application-context.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'test1dataSource' of bean class [org.springframework.orm.hibernate4.LocalSessionFactoryBean]: Bean property 'test1dataSource' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

您正在尝试在创建LocalSessionFactoryBean实例时将DataSource bean注入错误的属性名称。请尝试以下方法：

<property name="dataSource" ref="test1dataSource" />

＆＃34; NotWritablePropertyException＆＃34; Spring上下文初始化期间发生异常
