我有以下数据库架构（MySQL）：
我的登录是一个基于表单的身份验证系统，我正在尝试创建一个jdbc 领域。
我的 web.xml：
<login-config>
<auth-method>FORM</auth-method>
<realm-name>emdJDBCRealm</realm-name>
<form-login-config>
<form-login-page>/index.jsp</form-login-page>
<form-error-page>/WEB-INF/loginerror.jsp</form-error-page>
</form-login-config>
</login-config>
<security-constraint>
<web-resource-collection>
<web-resource-name>Login Page</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>adm</role-name>
<role-name>usr</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
<security-role>
<description/>
<role-name>usr</role-name>
</security-role>
<security-role>
<description/>
<role-name>adm</role-name>
</security-role>
sun-web.xml 中的映射：
<security-role-mapping>
<role-name>adm</role-name>
<group-name>adm</group-name>
</security-role-mapping>
<security-role-mapping>
<role-name>usr</role-name>
<group-name>usr</group-name>
</security-role-mapping>
我不知道为什么，但它对我不起作用，我得到以下信息：

我是否根据我拥有的数据库模式放置“准确”属性？感谢您的帮助，因为我不明白我做错了什么。
更新
这适用于任何有相同情况的人。
基于 @perissf ，GlassFish JDBC Realm 不支持规范化表。检查@perissf 的链接以获取有关架构应该如何的教程。
但是，我所做的是：
我保留了规范化模式并创建了一个 MySQL“视图”，其中包含所有必需的列：即列 [用户名、密码、组名]
-->我修改了Jdbc属性如下：
使用“视图”的原因是，正如@Matt Handy 所说，“JdbcRealm 要求用户表和组表中的用户名列名需要相同”
所以这在我的情况下会创建重复数据，因此我用了一个视图。
