在针对AppFuse 2.1（使用Spring Security 3.0.5和iBatis）动态定义安全URL时，有人可以帮助我解决“java.lang.IllegalArgumentException：No DataSource”问题吗？
在我开始动态定义安全URL之前，security.xml中的以下命名空间工作正常。
...
<http auto-config="false" lowercase-comparisons="false">
<intercept-url pattern="/images/**" filters="none"/>
<intercept-url pattern="/styles/**" filters="none"/>
<intercept-url pattern="/scripts/**" filters="none"/>
<intercept-url pattern="/app/admin/**" access="ROLE_ADMIN,ROLE_USER"/>
<intercept-url pattern="/app/passwordHint*" access="ROLE_ANONYMOUS,ROLE_ADMIN,ROLE_USER"/>
<intercept-url pattern="/app/signup*" access="ROLE_ANONYMOUS,ROLE_ADMIN,ROLE_USER"/>
<intercept-url pattern="/app/**" access="ROLE_ADMIN,ROLE_USER"/>
<form-login login-page="/login" authentication-failure-url="/login?error=true" login-processing-url="/j_security_check"/>
<remember-me user-service-ref="userDao" key="e37f4b31-0c45-11dd-bd0b-0800200c9a66"/>
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider user-service-ref="userDao">
<password-encoder ref="passwordEncoder"/>
</authentication-provider>
</authentication-manager>
...
但是在我注释掉元素并在security.xml中添加以下元素之后，由于没有指定数据源，“userDao”无效。

答案 0 :(得分：1)
如果您使用的是自定义用户服务，则需要参考：
<security:authentication-manager>
<security:authentication-provider user-service-ref="myUserDetailsService">
<security:password-encoder ref="md5" />
</security:authentication-provider>
</security:authentication-manager>
如果您正在使用JDBC并且只是针对一组表，那么您只需参考数据源：
<security:authentication-manager>
<security:authentication-provider>
<security:jdbc-user-service data-source-ref="my-ds"/>
<security:password-encoder hash="md5"/>
</security:authentication-provider>
</security:authentication-manager>
