JavaSpring概要文件：应该解析哪个<beans>元素？

Question

我在spring上下文中有以下配置：

<beans profile="!prof1" >
     <security:authentication-manager id="authenticationManager" erase-credentials="true">
                <security:authentication-provider ref="1" />
                <security:authentication-provider ref="2" />
                <security:authentication-provider ref="3" />
            </security:authentication-manager>
</beans>

<beans profile="prof1" >
     <security:authentication-manager id="authenticationManager" erase-credentials="true">
                <security:authentication-provider ref="0" />
                <security:authentication-provider ref="1" />
                <security:authentication-provider ref="2" />
                <security:authentication-provider ref="3" />
            </security:authentication-manager>
</beans>

在分析<beans>元素时会考虑以下问题： prof1和prof2配置文件被激活

看起来它总是选择这个<beans profile="prof1" >，但不确定为什么不选择另一个<beans profile="!prof1" >。我可以转告它总是选择<beans>而不带感叹号吗

Answer 1

如果您的活动配置文件是prof1和prof2，则以下配置文件将处于活动状态

<beans profile="prof1" >
 <security:authentication-manager id="authenticationManager" erase-credentials="true">
            <security:authentication-provider ref="0" />
            <security:authentication-provider ref="1" />
            <security:authentication-provider ref="2" />
            <security:authentication-provider ref="3" />
        </security:authentication-manager>

该Javadoc for Profile声明：

If a given profile is prefixed with the NOT operator (!), the annotated component will be registered if the profile is not active

（对于XMLBean定义，spring-beans XSD声明了相同的内容，但更难阅读。）

据我所知，对于带有profile=“！prof1”的bean元素，只查看prof1。同时激活prof2与此bean定义无关
