本来如果走到doGetAuthenticationInfo方法，从数据库查不到账户信息的话，应该抛出org.apache.shiro.authc.UnknownAccountException异常，提示账户不存在，但现在抛出的异常是 org.apache.shiro.authc.AuthenticationException,异常信息是从org.apache.shiro.authc.AbstractAuthenticator.authenticate(AbstractAuthenticator.java:216)里边拼接的信息

nutz的版本为1.r.66

debug看看dao()方法

在dao()方法里debug了一下，dao对象实例化了

[DEBUG] 2019-08-14 11:10:55.308 com.ex.mvc.shiro.realm.SysAccountRealm.dao(SysAccountRealm.java:176) - dao--------org.nutz.dao.impl.NutDao@540e6ffe

代码里提示报错的就是下面从数据库获取账户信息报错了

SysAccount loginAcc = dao().fetch(SysAccount.class, Cnd.where(SysAccount.ACCOUNT, "=", upToken.getUsername()));

[WARN ] 2019-08-14 11:10:55.310 org.apache.shiro.authc.AbstractAuthenticator.authenticate(AbstractAuthenticator.java:216) - Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - admin, rememberMe=false (127.0.0.1)].

日志里的at com.ex.mvc.shiro.realm.SysAccountRealm.doGetAuthenticationInfo(SysAccountRealm.java:103) 就是dao().fetch(...)方法那一行

nutzboot吗？没加nutzboot-starter-jdbc？

不是nutzboot 是直接用nutz框架整合shiro认证

声明dao的地方没注入dataSource吧

或者是这个dao实例是直接new的? 没setDataSource?

我知道了

Ehcache的问题

问题解决了，是配置dao缓存的问题

 // Dao实例对象
    dao: {
        type: "org.nutz.dao.impl.NutDao",
        args: [{
            refer: "dataSource"
        }],
        fields : {
            // interceptors : [{refer:"cacheExecutor"}, "log", "time"]
            executor : {refer : "cacheExecutor"}

        }
    },
    // Dao sql语句执行器
    cacheExecutor: {
        // type: "org.nutz.plugins.cache.dao.DaoCacheInterceptor",// todo 对应dao中  interceptors : [{refer:"cacheExecutor"}, "log", "time"]
        type : "org.nutz.plugins.cache.dao.CachedNutDaoExecutor", // todo 对应dao中 executor : {refer : "cacheExecutor"}
        fields: {
            cacheProvider: {refer: "cacheProvider"},
            // 需要缓存的表名
            cachedTableNames: [
                "sys_menu"
            ]
        }
    }

在dao.js中配置dao实例的 fields 部分，给成员变量赋值的时候，要注意配置的 daosql语句执行器 cacheExecutor的具体实现类。
org.nutz.plugins.cache.dao.DaoCacheInterceptor 对应dao中fields应该配置 interceptors : [{refer:"cacheExecutor"}, "log", "time"]
org.nutz.plugins.cache.dao.CachedNutDaoExecutor 对应dao中fields应该配置 executor : {refer : "cacheExecutor"}

我之前刚好配置反了，多谢！
