我尝试创建具有多个模块的 spring-boot 应用程序,其结构如下:
omnibus/
/domain
/persistence
/service
/web
在主 pom 中我设置了 spring-boot-starter-parent:
<?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">

<version>1.0-SNAPSHOT</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.5.RELEASE</version>
</parent>
<modules>
<module>persistence</module>
<module>domain</module>
<module>service</module>
<module>web</module>
</modules>
<properties>
<java.version>1.8</java.version>
<start-class>pl.omnibus.Application</start-class>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>

</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
在 web 模块中我包含了类:
package pl.omnibus;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
web模块的pom.xml如下:
<?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">
<parent>
<artifactId>omnibus</artifactId>
<groupId>omnibus</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>web</artifactId>
<dependencies>
<dependency>
<groupId>omnibus</groupId>
<artifactId>service</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
现在当我尝试执行时:
mvn package
在项目上,如果持久性模块的测试失败,因为它没有看到域的依赖性,尽管它是在持久性 pom.xml 中声明的:
<dependencies>
<dependency>
<groupId>omnibus</groupId>
<artifactId>domain</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
(...)
</dependencies>
奇怪的是这些命令成功通过:
mvn test
mvn package -DskipTests
但即使是后者,我也无法运行 web.jar,因为
java -jar web-1.0-SNAPSHOT.jar
对于域模块中的类,在 java.lang.NoClassDefFoundError 上失败。 我将不胜感激任何帮助,因为我是 spring-boot 的新手并且找不到创建具有多个模块的 spring-boot 应用程序的解决方案。
编辑: 我正在添加
的输出mvn dependency:tree

最佳答案
您的命令输出看起来很奇怪,因为您在问题中提到 groupId 是“app”,但是命令输出显示 groupId 是“omnibus”而不是 app。
尝试将依赖项更改为:
<dependencies>
<dependency>
<groupId>omnibus</groupId>
<artifactId>domain</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
(...)
所有其他模块依赖项也是如此。
