在多对多的映射关系模式下，用SET类型来存放目标的数据时，在读取数据的时候总是报FailToCastObjectException错误，但插入数据时又能正常执行。尝试着把SET类型换成LIST类型，任何执行操作没有问题！
JAVA代码：
.......
/**
* 状态
/
@column("status")
private Boolean status;
/*
* 用户角色映射
*/
@manymany(target = Roles.class, relation = "t_user_role", from = "userid", to = "roleid")
private Set roleses;
...........
附详细的BUG信息：
