如何配置JDBCRealm以从JNDI获取其数据源 [英] How to configure JDBCRealm to obtain its DataSource from JNDI
问题描述
如何使用JDBCRealm处理servlet中的用户身份验证和授权?我可以找到的唯一示例是在web.xml中创建数据源(例如
How do you use a JDBCRealm to handle authenticating and authorizing users in servlets? The only example I can find is to create the DataSource in web.xml (such as Authentication against database using shiro 1.2.1).
我不想在源代码树中包括数据库凭证(出于明显的原因)，并且更喜欢通过JNDI使用Context定义的数据源，就像我在所有其他servlet项目中用于其他任何目的的RDBMS一样我已经开发了.
I do not want to include database credentials in my source tree (for obvious reasons) and would prefer to use a Context defined DataSource via JNDI as I have for every other RDBMS I have used for any other purpose in every other servlet project I have developed.

推荐答案
Vrushank的答案真的很接近:您不需要在这里对JdbcRealm进行子类化-您可以使用Shiro的
Vrushank's answer was really close: you don't need to subclass the JdbcRealm here - you can use Shiro's JndiObjectFactory to acquire the DataSource and then reference that DataSource when you configure the JdbcRealm:
[main]
dataSource = org.apache.shiro.jndi.JndiObjectFactory
dataSource.resourceName = java://app/jdbc/myDataSource
jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.dataSource = $dataSource
#addt'l config
对于Web应用程序，将文件保存在WEB-INF/shiro.ini下.
For a web application, save the file under WEB-INF/shiro.ini.
