Spring maven项目在旧版本IDEA运行正常，新版IDEA报错 java.lang.IllegalStateException: Logback configuration error detected

1. 旧版IDEA 

IntelliJ IDEA 2018.2.3 (Community Edition)
Build #IC-182.4323.46, built on September 4, 2018
JRE: 1.8.0_152-release-1248-b8 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Windows 10 10.0

2. 新版IDAE（不是最新版，只是比旧版新而已）

IntelliJ IDEA 2021.1 (Community Edition)
Build #IC-211.6693.111, built on April 6, 2021
Runtime version: 11.0.10+9-b1341.35 amd64
VM: Dynamic Code Evolution 64-Bit Server VM by JetBrains s.r.o.
Windows 10 10.0
GC: G1 Young Generation, G1 Old Generation
Memory: 1526M
Cores: 4

Kotlin: 211-1.4.32-release-IJ6693.72

运行报错：

java.lang.IllegalStateException: Logback configuration error detected: 
ERROR in c.q.l.core.rolling.SizeAndTimeBasedRollingPolicy@996533593 - Timeouxxxxxx后面错误省略

解决办法：

将pom.xml中

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.logging.log4j</groupId>
                    <artifactId>log4j-to-slf4j</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

　　

提到  dependencies 的最前面

解释：pom文件的加载顺序也是从上至下执行，放到pom文件中的第一位，在向下执行的时候也会排除所有的默认logger了。
