执行两次Spring控制器方法

我已经将Spring安全性与Spring MVC集成在一起，并看到了奇怪的行为。控制器中的每个方法针对同一请求执行两次。我在谷歌上搜索了不少，但没帮上什么忙。我能找到的最接近的答案是，我尝试了这些建议，但没有成功

这是我的web.xml：

<servlet>
     <servlet-name>appServlet</servlet-name>
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <load-on-startup>0</load-on-startup>
</servlet>     
<servlet-mapping>
     <servlet-name>appServlet</servlet-name>
     <url-pattern>/</url-pattern>
</servlet-mapping>

<listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<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>

<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>
         /WEB-INF/spring/appServlet/security-app-context.xml            
         /WEB-INF/application-context.xml
    </param-value>
</context-param>

appServlet
org.springframework.web.servlet.DispatcherServlet
0
appServlet
/
org.springframework.web.context.ContextLoaderListener
springSecurityFilterChain
org.springframework.web.filter.DelegatingFilterProxy
springSecurityFilterChain
/*
上下文配置位置
/WEB-INF/spring/appServlet/security-app-context.xml
/WEB-INF/application-context.xml

以下是applicationcontext.xml的相关部分：

 <context:component-scan base-package="com.*" />
  <context:spring-configured/>

 <mvc:annotation-driven />

 <context:property-placeholder location="classpath:/conf/myConfig.properties"   />

<mvc:resources mapping="/resources/**" location="/resources/" />

servlet-context.xml仅具有InternalResourceViewResolver的映射

security-context.xml如下所示：

<http pattern="/resources/**" security="none"/>

    <http auto-config="false" create-session="stateless" entry-point-ref="loginUrlAuthenticationEntryPoint" >
        <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
        <intercept-url pattern="/j_spring_security_check" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
        <intercept-url pattern="/accessdenied" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
        <intercept-url pattern="/login" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
        <intercept-url pattern="/logout" access="ROLE_USER"/>

    <custom-filter before="SECURITY_CONTEXT_FILTER" ref="cookieSecurityContextFilter" />
    <custom-filter position="LOGOUT_FILTER" ref="logoutfilter" />          
    <custom-filter position="FORM_LOGIN_FILTER" ref="authenticationFilter" />
    <custom-filter after="EXCEPTION_TRANSLATION_FILTER" ref="customExceptionFilter" />
    </http>


    <beans:bean id="logoutfilter" class="org.springframework.security.web.authentication.logout.LogoutFilter">
     <beans:constructor-arg value="/"/>
     <beans:constructor-arg ref="customLogouthandler"/>
    </beans:bean>

然后进一步映射过滤器。 我是否在配置中出错，从而导致控制器被调用两次。我检查了日志，bean只实例化了一次。请帮忙

提前感谢。

我会尝试移动

，以防有人无意中发现此帖子和此处发布的解决方案，认为它将修复重复的请求，请首先检查是否是您的浏览器/rest客户端进行了额外呼叫

“在看到第一个建议的解决方案之后”，我浪费了很多时间试图配置应用程序和servlet上下文，直到我发现是某些浏览器（Chrome）上的rest客户端创建了一个额外的“获取图像资源请求”请求。Curl只显示了一个方法执行

然而，我同意将特定于控制器的bean和它们所需的springbean分离到servlet上下文中，并将所有公共bean保留在应用程序上下文中是一个很好的实践。如果web.xml中有多个Spring dispatcher servlet，这一点尤其重要

详细说明先前的答复：

您可以在同一个上下文文件中定义组件扫描和mvc，以保持简单

app-context.xml：

 <context:component-scan base-package="..." />
 <mvc:annotation-driven />
 ...

 <context:component-scan base-package="....">
    <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
<context:exclude-filter expression="org.springframework.web.bind.annotation.ControllerAdvice" type="annotation"/>
<context:exclude-filter expression="org.springframework.web.bind.annotation.ExceptionHandler" type="annotation"/>
</context:component-scan>
...

<context:component-scan base-package="...">
    <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    <context:include-filter expression="org.springframework.web.bind.annotation.ControllerAdvice" type="annotation"/>
    <context:include-filter expression="org.springframework.web.bind.annotation.ExceptionHandler" type="annotation"/>
</context:component-scan>

<mvc:annotation-driven />

...


...

或按如下方式将其分开：

app-context.xml：

 <context:component-scan base-package="..." />
 <mvc:annotation-driven />
 ...

 <context:component-scan base-package="....">
    <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
<context:exclude-filter expression="org.springframework.web.bind.annotation.ControllerAdvice" type="annotation"/>
<context:exclude-filter expression="org.springframework.web.bind.annotation.ExceptionHandler" type="annotation"/>
</context:component-scan>
...

<context:component-scan base-package="...">
    <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    <context:include-filter expression="org.springframework.web.bind.annotation.ControllerAdvice" type="annotation"/>
    <context:include-filter expression="org.springframework.web.bind.annotation.ExceptionHandler" type="annotation"/>
</context:component-scan>

<mvc:annotation-driven />

...


...

servlet-context.xml：

 <context:component-scan base-package="..." />
 <mvc:annotation-driven />
 ...

 <context:component-scan base-package="....">
    <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
<context:exclude-filter expression="org.springframework.web.bind.annotation.ControllerAdvice" type="annotation"/>
<context:exclude-filter expression="org.springframework.web.bind.annotation.ExceptionHandler" type="annotation"/>
</context:component-scan>
...

<context:component-scan base-package="...">
    <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    <context:include-filter expression="org.springframework.web.bind.annotation.ControllerAdvice" type="annotation"/>
    <context:include-filter expression="org.springframework.web.bind.annotation.ExceptionHandler" type="annotation"/>
</context:component-scan>

<mvc:annotation-driven />

我在applicationcontext.xml中添加了以下内容，并在servlet-context.xml中添加了以下内容：。还尝试了移动。请共享服务器日志。此外，spring安全拦截器URL也按声明顺序应用。最后移动全局拦截器/**（并不是说它将有助于解决控制器问题）
