spring+hibernate事务处理

Spring包含Hibernate事务的配置文件applicationContext.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"
    default-autowire="byName" default-lazy-init="true">

    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName">
            <value>org.gjt.mm.mysql.Driver</value>
        </property>
        <property name="url">

        <property name="username">

        </property>
        <property name="password">

        </property>
    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref local="dataSource" />
        </property>
        <property name="mappingResources">
            <value>test/customer.hbm.xml</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQLDialect
                </prop>
            </props>
        </property>
    </bean>

    <!--  Transaction配置开始 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>
    <!--  Transaction配置结束 -->

    <bean id="custManageServiceTarget" class="test.CustomerDao">
        <property name="sessionFactory">
            <ref bean="sessionFactory" />
        </property>
    </bean>

    <bean id="customerDao"
        class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager">
            <ref bean="transactionManager" />
        </property>
        <property name="target">
            <ref bean="custManageServiceTarget" />
        </property>
        <property name="proxyTargetClass">
            <value>true</value>
        </property>
        <property name="transactionAttributes">
            <props>
                <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>

    <!--  Action及其Service被配置在applicationContext-XXX中 -->
    <!--  示例Customer action and dao -->
    <bean id="customerAction" scope="prototype"
        class="test.CustomerAction">
        <property name="custDao">
            <ref bean="customerDao" />
        </property>
    </bean>

</beans>

 注意 事务中的一段：
            <property name="proxyTargetClass">
            <value>true</value>
        </property>
如果没有这一段，动态注入的时候就会出现conversion错误。类似如下：

org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy12 to required type

[com.brilliance.struts.service.impl.InvestServiceImpl] for property 'fundService'; nested exception is

java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy1] to required type

[com.brilliance.struts.service.impl.InvestServiceImpl] for property 'fundService': no matching editors or conversion strategy
