IDEA下Logback.xml自动提示功能配置

首先打开logback的配置文件，在configuration标签中加入xsd的配置

<configuration  xmlns="http://ch.qos.logback/xml/ns/logback"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://ch.qos.logback/xml/ns/logbackhttps://raw.githubusercontent.com/enricopulatzo/logback-XSD/master/src/main/xsd/logback.xsd">
</configuration>

然后将鼠标光标放到https://raw.githubusercontent.com/enricopulatzo/logback-XSD/master/src/main/xsd/logback.xsd 的红色区域上，按alt+enter, 点击fetch external resource，会自动下载xsd文件。

如果无法下载，则在resource下创建logback.xsd文件
