多对多关系:

@ManyMany(relation = "sys_role_user",from = "user_account:user_account",  to = "pk_role_id")
    private List<SysRole> roles;

java代码:

log.info(user.getRoles());
            log.info(user.getUser_account());
            dao.fetchLinks(user, null);
            log.info(user.getRoles());

其中的 45 是user的id值,不是说:
你为 from 声明了一个 "pid:name",这个冒号后面的,就是大声告诉 NutDao 请用 Pet.name 来映射这个 pid 字段。这样 NutDao 就不会自己瞎猜了。

没看懂你想说什么

按照@ManyMany 的设置 应该是:

SELECT * FROM sys_role  WHERE pk_role_id IN (SELECT pk_role_id FROM sys_role_user WHERE user_account=‘admin’)

条件应该是

SELECT pk_role_id FROM sys_role_user WHERE user_account=user.getUser_account

实际上是

SELECT pk_role_id FROM sys_role_user WHERE user_account=user.getId

这个 from = "user_account:user_account" 没起作用啊 ,user_account 是普通的字段,没加@Id @Name

from = "user_account:user_account" 

冒号后面不是已经指定了user_account字段 ,而nutz在执行时 却使用了下面这个

@Id
 private int pk_user_id

求解答

3个POJO都贴一下, 感觉哪里不对呢

主要逻辑在 ManyManyLinkField 里面

user类:

java代码块:
这个代码是在controller层

log.info(user.getRoles());
log.info(user.getUser_account());
dao.fetchLinks(user, null);
log.info(user.getRoles());

对应的日志:

[INFO ] 2017-10-10 08:44:49,843 com.kmia.mdkj.contract.action.sys.loginAction 
[INFO ] 2017-10-10 08:44:49,843 com.kmia.mdkj.contract.action.sys.loginAction admin

[INFO ] 2017-10-10 08:44:49,883 com.kmia.mdkj.contract.action.sys.loginAction []

在这个日志中 WHERE role_name IN 这个 role_name 并不是想要的
我想要的执行语句为下面这个:

SELECT * FROM sys_role  WHERE pk_role_id IN (SELECT pk_role_id FROM sys_role_user WHERE user_account='admin')

当我把user类的多对多改成:

@ManyMany(relation = "sys_role_user",from = "user_account:user_account",  to = "pk_role_id:pk_role_id")
    private List<SysRole> roles;
