我正在尝试配置多模块Spring启动应用程序。最简单的例子是:
pom1
<?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"

<modelVersion>4.0.0</modelVersion>
<groupId>testExample</groupId>
<artifactId>testExample</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.2.RELEASE</version>
<relativePath/>

<build>
<plugins>
<plugin>

<version>3.1</version>
<configuration>

<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
<modules>
<module>module1</module>
</modules>
</project>
pom2:
<?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"

</build>
<dependencies>
<dependency>

RootConfig:
package testExamplePackage;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class RootConfig {
public static void main(String[] args) {
System.out.println("Doing some work...");
}
}
为什么我得到一个ERROR启动maven'clean spring-boot:run'?

它需要mainClass,但已指定此类。
答案 0 :(得分:2)
mvn clean spring-boot:run
必须从包含SpringBootApplication
的模块执行
你从父pom执行它。
从module1
执行此命令,它应该可以正常工作。
顺便说一句,module1
pom.xml中的重复声明不是必需的,因为它已由您的父指定:
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
答案 1 :(得分:0)
我就是这样做的。
从多模块项目的根目录运行:
mvn -pl module1 spring-boot:run
现在,如果您的多模块 Spring Boot 项目的根目录中有一个 config
文件夹,Spring-boot 还将扫描该文件夹中的属性文件(除了 src/main/resources),使这些属性适用于所有模块。
