logback 问题 ch.qos.logback.core.joran.spi.JoranException: Parser configuration error occurred-优快云博客

本文链接：https://blog.youkuaiyun.com/power_to_go/article/details/133794917

博客主要围绕 logback 相关问题展开，介绍了两种解决方法。一是针对引入的依赖 javax.xml.parsers.SAXParserFactory 有多个实现且不支持 logback 特性的情况，将其设置为支持 logback 特性的实现类；二是排除引入的其他 xml parser，如 oracle database xml 里的 xmlparser，并给出了 gradle 配置参考链接。

法1: SAX feature 问题解决方法

引入的依赖 javax.xml.parsers.SAXParserFactory 有多个实现。使用的不支持 logback 的特性。设置 SAXParserFactory 为支持 logback 特性的实现类。

    System.setProperty("javax.xml.parsers.SAXParserFactory","com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");

法2: 排除引入的其他的 xml parser

比如排除 oracle database xml 里的 xmlparser
gradle 配置如下:

configurations {
    runtime.exclude group: "com.oracle.database.xml", module: "xmlparserv2"
    compile.exclude group: "com.oracle.database.xml", module: "xmlparserv2"
}
