这个异常不太好判断。
Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister
这个debug进去也不知道到底怎么回事。只知道是反射获取实体类对象时出了错。


在网上查了一下, 大概有以下几种原因:

1. 实体类的属性对象没有设置setter或者getter。
http://stackoverflow.com/questions/18042247/could-not-get-constructor-for-org-hibernate-persister-entity-singletableentitype

2. 没有导入javassist的jar文件  (javassist-3.15.0-GA.jar什么的)
http://blog.csdn.net/xiaochangwei789/article/details/7712725

3. 我这次出错的原因。
我的实体类中的属性对象名和映射文件的property name不一致。

private String team_name;
<property name=" team" column="team_name" type="string"/>

这里只要改成:
private String team_name;
<property name="team_name"...
就好了。
