1.父模块中的配置.

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        
        
        <parent>
            <groupId>com.carl.study</groupId>
            <artifactId>xx-yy</artifactId>
            <version>xxxx</version>
        </parent>
        
            
            
            
            
        
    
        <groupId>com.carl.study.springcloud</groupId>
        <artifactId>cloud-demo-parent</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <packaging>pom</packaging>
        <name>cloud-demo-parent</name>
        <description>Demo project for Spring Boot</description>
    
    
        
        <dependencyManagement>
            <dependencies>
                
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-dependencies</artifactId>
                    <version>2.1.6.RELEASE</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                
                <dependency>
                    <groupId>cn.hutool</groupId>
                    <artifactId>hutool-all</artifactId>
                    <version>4.6.0</version>
                </dependency>
            </dependencies>
        </dependencyManagement>
    
        <build>
            <pluginManagement>
                <plugins>
                    <plugin>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-maven-plugin</artifactId>
                        <version>2.1.6.RELEASE</version>
                        
                        <configuration>
                            <fork>true</fork>
                            <includeSystemScope>true</includeSystemScope>
                        </configuration>
                    </plugin>
                </plugins>
            </pluginManagement>
        </build>
    
    </project>

2. 子模块中的配置, 父模块中的相应修改会导致打包后的jar包不能在直接使用java -jar运行, 会提示找不到主类(因打包的时候没有执行spring-boot-maven-plugin的repackage目标)

<plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        
        <configuration>
            <fork>true</fork>
            <includeSystemScope>true</includeSystemScope>
        </configuration>
        
        <executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

加上repackage目标后的主要日志记录变化:

修改后, 子模块中相关的配置可能引用不到, 可以先注释掉子模块中关于springboot的配置, 待其加载完成后, 重新打开.
