How to find what apache.xerces version does spring-framework use?

问题

I am using Spring-framework v5.2.1.RELEASE. The DefaultDocumentLoader.java in spring bean factory has following code:

import javax.xml.parsers.DocumentBuilder;
...
DocumentBuilder builder = createDocumentBuilder(factory, entityResolver, errorHandler);

I know that spring uses apache.xerces.internal.parsers. But I don't know which version of Xerces does it use? In spring directory, I did gradlew -q dependencies and searched the dependency list. I did not find xerces or parsers. How to figure out the xerces version in use?

回答1:

It uses the JDK's default library for XML parser. So, it is not using any third party jar for parsing XML.

Basically, it is using the rt.jar of your jdk/../jre/lib directory for getting classes to parse XML.

The package it is using is : com.sun.org.apache.xerces.*
