我有一个烦人的错误,我有一段时间无法解决。我最近被介绍到基于容器的安全性并尝试实现它。我已将领域配置如下:
<Realm className="org.apache.catalina.realm.JDBCRealm"
debug="99"
driverName="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://127.0.0.1:3306/identify"
connectionName="adm" connectionPassword="pw"
userTable="users" userNameCol="login"
userCredCol="password"
allRolesMode="authOnly" />
</Realm>
不幸的是,我无法使用此登录。日志错误消息是:
SEVERE: Exception performing authentication
java.sql.SQLException: You have an error in your SQL syntax;

请注意用户名周围的 ''... 这是正确的吗?
如您所见,我也使用allRolesMode="authOnly"
,因为我不需要此功能,而且数据库没有并且永远不会有额外的用户角色列(如果不使用它,那么每个用户都会使用它是毫无意义的在此列中具有相同的值 - 资源浪费很大。)。
服务器是Tomcat 7.0.19
