當我試圖用彈簧安全通過數據庫來驗證,我用Google搜索了幾個例子,它們都類似這樣的疑問:Spring jdbc SQL糟糕的語法異常,是選擇列嚴格嗎?
<authentication-manager>
<authentication-provider>
<jdbc-user-service data-source-ref="dataSource"
users-by-username-query="
select username,password, enabled
from users where username=?"
authorities-by-username-query="
select u.username, ur.authority from users u, user_roles ur
where u.user_id = ur.user_id and u.username =? "
/>
</authentication-provider>
</authentication-manager>
是錯的,如果我將改變查詢類似如下?如果不是爲什麼?
<security:authentication-manager>
<security:authentication-provider>
<security:jdbc-user-service data-source-ref="dataSource"
users-by-username-query="select login.name,login.passw from login where login.name=?"
authorities-by-username-query="select login.name, login.type from login where login.name =?"/>
</security:authentication-provider>
</security:authentication-manager>
這個例子給出了一個不好的SQL異常。
