流云溪|码农问题出在：could not initialize proxy - no Session at 无法初始化代理-没有session。 证明获取不到session，访问action的时候报了500错误，
配置懒加载一定要在web.xml开头配置代码，放在其他位置无效。
解决办法：这个是 由于web.xml没有配置懒加载。名词解析：延迟加载，也叫懒加载，它是Hibernate为提高程序执行效率而提供的一种机制，即只有真正使用该对象的数据时才会创建。
在web.xml里面配置懒加载，代码如下：
<!-- 配置过滤器，解决hibernate延迟加载问题 --> <filter> <filter-name>openSessionInView</filter-name> <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>openSessionInView</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
最最最重要的一点是，其他博客都没有提到的，但是有必须要做的，配置懒加载一定要在web.xml开头配置代码。
我的web.xml配置如下：
这样即可完美解决。
