我是在自学中，按照视频做，此处错误出现在Hibernate 反转 映射，表1：PetInfo 表2：PetDiary
此处错误是在反转生成的entity.PetInfo中出现 想不通...
private Set<PetDiary> diarts = new HashSet<PetDiary>();
报错：Multiple markers at this line
- The type HashSet is not generic; it cannot be parameterized with
arguments <PetInfo>
- Syntax error, parameterized types are only available if source level
is 5.0
- The type Set is not generic; it cannot be parameterized with
arguments <PetInfo>
- Syntax error, parameterized types are only available if source level
is 5.0
------解决方案--------------------
那应该是编译级别的问题，你修改下你工程的编辑为5.0就好啦
右键点击你工程，properties-->java compiler--->右边有选项config workspace setting
-->修改compiler compilance level,修改成5.0即可
