java.lang.IllegalStateException：BeanFactory 未初始化或已关闭 - 在通过 ApplicationContext 访问 Bean 之前调用“刷新”

java spring spring-security

2022-09-03 07:46:07

我需要将带有自定义登录页面和数据库连接的Spring Security添加到我的Spring MVC项目中。我收到以下错误消息，根据其他问题的答案，我试图更改代码，例如，我将Spring安全架构版本更改为4.0，但代码返回以下错误：

架构更改为 4.0

http://www.springframework.org/schema/security/spring-security-4.0.xsd

错误

Cannot initialize context because there is already a root application context 
present - check whether you have multiple ContextLoader* definitions in your 
web.xml!

我认为你只需要一个xml配置文件（my-servlet.xml因为你的servlet名称是“my”，所以文件名必须是“my-servlet.xml”），然后在该文件中引用其他文件。请参阅下面的 xml。

<xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">
    <listener>
        <listener-class>org.apache.tiles.extras.complete.CompleteAutoloadTilesListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
        <servlet>
            <servlet-name>my</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>/WEB-INF/my-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
    </servlet>

</web-app>

在 my-servlet.xml 文件中，可以使用 import 来编写其他 XML 配置。

<beans>
  <bean id="bean1" class="..."/>
  <bean id="bean2" class="..."/>

  <import resource="security-db.xml"/>
  <import resource="foo-db.xml"/>
</beans>

添加到您的网站.xml：DelegatingFilterProxy

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>my</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>my</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:config/security-config.xml</param-value>
    </context-param>
</web-app>

添加为 Web 应用程序上下文配置。将元素添加到：my-servlet.xml/webapp/WEB-INF/authentication-managermy-security.xml

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

       <http auto-config="true" use-expressions="true">
              <intercept-url pattern="/" access="permitAll" />
       </http>

       <authentication-manager>
              <authentication-provider>
                     <user-service>
                            <user name="username" authorities="ROLE_ADMIN" password="password" />
                     </user-service>
              </authentication-provider>
       </authentication-manager>
</beans:beans>

摆脱和使用，就像Mkyong在这里所做的那样access-denied-pageaccess-denied-handler
