spring中排除某个类

在spring中可能需要排除某个类，做法是在spring配置文件中加入如下配置

<context:component-scan base-package="com.ias" use-default-filters="false">
        <context:exclude-filter type="assignable" expression="com.ias.agdis.terminal.rest.impl.endpoint.SecurityEndpointImpl"/> 
</context:component-scan>

配置效果如下图所示：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.0.xsd
            http://camel.apache.org/schema/spring
            http://camel.apache.org/schema/spring/camel-spring-2.16.1.xsd">

    <context:component-scan base-package="com.ias" use-default-filters="false">
        <context:exclude-filter type="assignable" expression="com.ias.agdis.terminal.rest.impl.endpoint.SecurityEndpointImpl"/> 
    </context:component-scan>
    
    <!-- 将配置文件读取到容器中，交给Spring管理 -->
    <bean id="configProperties"
        class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="locations">
            <list>
                <value>classpath:jdbc_mysql.properties</value>
                <value>classpath:config.properties</value>
            </list>
        </property>
        <!-- 设置编码格式 -->
        <property name="fileEncoding" value="UTF-8"></property>
    </bean>
    <!-- 将多个配置文件位置放到列表中 -->
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">  
        <property name="properties" ref="configProperties" />  
    </bean>
