解決org.hibernate.LazyInitializationException: could not initialize proxy - no Session

原因： hibernate懶加載導致的。 當查詢時，session已關閉。

解決方法：在web.xml 加入以下代碼

hibernate

	<filter>
		<filter-name>Spring OpenEntityManagerInViewFilter</filter-name>
		<filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
		<init-param>
			<param-name>entityManagerFactoryBeanName</param-name>
			<param-value>entityManagerFactory</param-value>
		</init-param>
		<async-supported>true</async-supported>
	</filter>

	<filter-mapping>
		<filter-name>Spring OpenEntityManagerInViewFilter</filter-name>
		<url-pattern>*.do</url-pattern>
	</filter-mapping>

添加jar包
