在Struts2 + Hibernate4 + Spring3.2 整合的時候出現的:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'name' of bean class [org.apache.commons.dbcp.BasicDataSource]: Bean property 'name' is not writable or has an invalid setter method.

我的applicationContext.xml設定檔是這樣的:
<?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:contex="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="testService" class="com.ssh.test.TestService" p:name="這是一個測試屬性值"></bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://127.0.0.1:3306/ssh"/> <property name="name" value="root"/> <property name="password" value="root"/> <property name="initialSize" value="3"/> <property name="maxActive" value="500"/> <property name="maxIdle" value="2"/> <property name="minIdle" value="1"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list> <value>com/ssh/domain/Employee.hbm.xml</value> </list> </property> </bean> </beans>
原來是:
<property name="name" value="root"/>
寫錯了,改成:
<property name="username" value="root"/>
問題解決。
