@ManyMany(from = "userId", relation = "sys_user_unit", target = Sys_role.class, to = "unitId")
    protected List<Sys_unit> units;

是不是应该改为：

@ManyMany(from = "userId", relation = "sys_user_unit", target = Sys_unit.class, to = "unitId")
    protected List<Sys_unit> units;

同时，请教一下，在前面：

@One(target = Sys_unit.class, field = "unitid")
    private Sys_unit unit;

这个sys_unit和sys_user的对应关系是，一对一，还是一对多呢？
