java - spring-boot 在多模块应用程序上失败

标签 java spring maven spring-boot

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"

    <module>domain</module>
    <module>service</module>

            <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。
