（九）Hibernate 检索策略

标签：

所有项目导入对应的hibernate的jar包、mysql的jar包和添加每次都需要用到的HibernateUtil.java

这里的hibernate.cfg.xml配置信息我就不再写了

第一节：检索策略属性Lazy

Lazy:true (默认) 延迟检索；set 端一对多

Lazy:false 立即检索；set 端一对多

Lazy:extra 增强延迟检索； set 端一对多

Lazy:proxy(默认) 延迟检索；many-to-one 多对一

Lazy:no-proxy 无代理延迟检索；many-to-one 多对一(需要编译时字节码增强)

Lazy:true (默认) 延迟检索；set 端一对多
