Question

使用Xpath查询我想获得这两个元素

<security:http realm="Protected API" use-expressions="true" auto-config="false" create-session="always"
                       entry-point-ref="authenticationEntryPoint">
            <security:custom-filter ref="covAuthFilter" position="FORM_LOGIN_FILTER"/>

从这个春天的配置文件

我尝试了以下内容：

//s:beans//security:http[1]

//security:http[1]

无济于事，tnx。我将在maven maven-config-processor-plugin上使用它，并在打包或安装过程中在弹簧配置上动态插入内容。

Answer 1

如果在xpath中使用名称空间，则必须在使用xapth的上下文中定义名称空间。

如果不可能，你可以像这样使用通配符：

//*:http[1]

我刚刚看到你正在使用allows to define命名空间上下文的maven插件。我想你可以使用它来定义你在xpath中使用的命名空间，而不是依赖通配符。

Spring Bean应用程序上下文的XPath查询
