异常：could not initialize proxy - no Session

异常：

严重: could not initialize proxy - no Session
org.hibernate.LazyInitializationException: could not initialize proxy - no Session
	at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:167)
	at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:215)
	at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:191)

原因：

        Hibernate3 many-to one 的 默认选项是 lazy = "proxy"

       解决：

       

@ManyToOne(cascade={CascadeType.REFRESH,CascadeType.MERGE},fetch=FetchType.LAZY)

    把后面 fetch=FetchType.LAZY   去掉

    如果是Hibernate2,many-to-one 设置 lazy="false".
