Spring中的错误：org.springframework.beans.factory.NoSuchBeanDefinitionException：

Question

我在弹簧安全性的集成中遇到了这个错误：

  

org.springframework.beans.factory.NoSuchBeanDefinitionException：没有   名为'springSecurityFilterChain'的bean已定义

这是我的pom.xml

这是ApplicationContext类：

@ComponentScan(basePackages = "com.server.rest.resource") //Transaction management 
@ImportResource("/WEB-INF/applicationContext.xml")

}

这是我的spring-security.xml

如果你能帮我解决问题，我将不胜感激。提前致谢

Answer 1

Spring DelegatingFilterProxy期望在<filter-name>中声明名称的bean。在您的情况下，这是springSecurityFilterChain，但似乎您的应用程序上下文中没有这样的bean。

查看this主题中的最后一篇文章。

您似乎需要明确使用Spring的security命名空间来生成springSecurityFilterChain。因此，将名称空间添加到所有spring-security.xml元素中。 （确保将默认命名空间更改为beans或其他内容。）

替换为

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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">

    <security:http auto-config="true">
        <security:intercept-url pattern="/rest*" access="ROLE_USER" />
    </security:http>

    <security:authentication-manager>
        <security:authentication-provider>
            <security:user-service>
                <security:user name="user" password="user" authorities="ROLE_USER" />
            </security:user-service>
        </security:authentication-provider>
    </security:authentication-manager>

</beans>

您的web.xml中还有其他错误/不需要的东西。它应该是这样的：

<!--?xml version="1.0" encoding="UTF-8"?? -->

ContextLoaderListener加载应用程序的根上下文。您应该只将ApplicationContext上下文（您的@Configuration类）加载它。您的DispatcherServlet加载的所有其他上下文都是根上下文的子项，因此可以引用其中的bean。那里你的DispatcherServlet只需要加载/WEB-INF/spring-security.xml上下文（可能还有一个与MVC相关的bean的上下文，但它看起来不像你在这里。）因为这是一个xml文件，你需要XmlWebApplicationContext。
