Question

我正在尝试在GlassFish v3.1.2应用服务器上的JavaEE6 Web应用程序中使用Apache Shiro（v1.2）。

在GlassFish中，我已经设置了一个数据源（jdbc/myds），我已通过JPA2测试了该数据源。

我想使用相同的数据源来验证使用Shiro JDBC领域的用户。

我在shiro.ini中有以下内容：

# DataSource config
ds                = org.apache.shiro.jndi.JndiObjectFactory 
ds.requiredType   = javax.sql.DataSource
ds.resourceName   = jdbc/myds

# JDBC realm config
jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.permissionsLookupEnabled = false
jdbcRealm.authenticationQuery = SELECT password FROM user_account WHERE email = ?
jdbcRealm.userRolesQuery = SELECT role_name FROM user_group_membership WHERE email = ?
jdbcRealm.dataSource = $ds

当我部署应用程序时，我得到以下异常（摘要）：

FINE: Encountered object reference '$ds'.  Looking up object with id 'ds'
FINEST: Applying property [dataSource] value [org.apache.shiro.jndi.JndiObjectFactory@2ca061] on object of type [org.apache.shiro.realm.jdbc.JdbcRealm]

如果我定义一个实际的MySQL数据源，它可以正常工作，例如

ds = com.mysql.jdbc.jdbc2.optional.MysqlDataSource 
ds.serverName = localhost
ds.user = root
ds.password = root
ds.databaseName = mydb

非常感谢任何帮助。

这看起来很可能是类路径问题。堆栈跟踪引用了在shiro 1.1.0中有意义的ReflectionBuilder的行号。然而，它们在shiro 1.2.0中没有意义。但是，由于JndiObjectFactory在shiro 1.2.0中是新的，并且两个类都在shiro-core中，所以你可能在类路径上都有两个jar。

您应首先查看您的war文件，确保两个罐子都不在那里。如果是，您可以通过删除1.1.0版本来修复war文件。如果没有，我会开始寻找你是否通过玻璃鱼基础设施以某种方式继承旧版本的shiro。

带有JdbcRealm和JndiObjectFactory的Apache Shiro会抛出IllegalArgumentException
