Spring 整合Hibernate時報錯:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'annotatedClasses' of bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Bean property 'annotatedClasses' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
......
原因在於選擇Hibernate的sessionFactory時有兩種:
1. LocalSessionFactoryBean,使用*.hbm.xml進行配置,並且bean的class是hibernate3.LocalSessionFactoryBean:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="mappingResources"><list><value>User.hbm.xml</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop></props></property></bean>
2. AnnotationSessionFactoryBean,bean的class是AnnotationSessionFactoryBean
<bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="annotatedClasses</span>"><list><value>com.xxx.model.User</span></value></list></property><property name="hibernateProperties"><!-- <value>hibernate.dialect=org.hibernate.dialect.HSQLDialect</value> --> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> </props></property></bean>
在擷取session的時候,使用Session s = sessionFactory.openSession();
