创建名为'；org.springframework.security.filterChains

这是我的dispatcher-servlet.xml

调试后，我得到一个错误

在

security.xml

配置中定义您的

userdetail

bean，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
 xmlns:beans="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
       http://www.springframework.org/schema/security
       http://www.springframework.org/schema/security/spring-security-3.2.xsd">

<http use-expressions="true">
<intercept-url pattern="/add_role.htm" access="hasRole('ROLE_ADMIN')" />
<form-login login-page="/login.htm"/>
<logout logout-url="/logout"/>
 </http>


<authentication-manager>
<authentication-provider user-service-ref="userdetail">
    <password-encoder hash="bcrypt" />
</authentication-provider>
</authentication-manager>

<beans:bean id="userdetail" class="com.controller.UserDetail" />
</beans:beans>

它是定义的，其他问题我知道您在

dispatcher servlet.xml中定义了它，但spring容器无法识别它。将
userdetail
bean定义从
dispatcher servlet.xml
复制到
security.xml
。仔细查看stacktrace:
NoSuchBean定义异常：未定义名为“userdetail”的bean
