Hibernate常见异常及解决办法（1）

Illegal attempt to map a non collection as a @OneToMany, @ManyToMany or @CollectionOfElements异常

private HashSet<jobExperience> jobExperiences = new HashSet<jobExperience>();

这里改成

private Set<jobExperience> jobExperiences = new HashSet<jobExperience>();

同时修改相应的getter和setter方法，即可。
