spring-boot 在多模块应用程序上失败答案

【问题标题】：spring-boot fails on multi-module appspring-boot 在多模块应用程序上失败
【发布时间】：2023-03-19 10:11:01
【问题描述】：

我尝试创建包含多个模块的 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">

</parent>

<modules>
    <module>persistence</module>
    <module>domain</module>
    <module>service</module>
    <module>web</module>
</modules>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </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

如果持久性模块测试失败，则在项目上，因为它没有看到域的依赖关系，尽管它在持久性 pom.xml 中声明：

<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了：

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

对于来自域模块的类的 java.lang.NoClassDefFoundError 失败。我会很感激任何帮助，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

【问题讨论】：

这与 Spring Boot 无关，完全是 Maven 问题。从您的顶级目录发布dependency:tree 的输出。
java -jar web-1.0-SNAPSHOT.jar 将无法解决问题，除非您使用 maven 插件重新打包所有依赖项或生成包含所有依赖项。对不起，我手头没有例子可以分享，但你可以read the docs
@Augusto 我认为根据这个docs使用spring-boot-maven-plugin 时有可能@
是的，spring-boot-maven-plugin 有一个目标来处理它。无需添加任何其他内容。请参阅下面的答案以获取建议的修复方法。
spring-boot:run 怎么样？我用它来运行单个 Spring Boot Web 应用程序。然后我在那里添加新的父 pom 和另一个模块。之后我遇到了和你一样的问题——找不到依赖。我想执行 spring-boot:run，但是在哪里呢？在父母 pom?在网络应用模块？有人可以帮忙吗？

【解决方案1】：

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。

这是我的错误 - 我同时将名称从 app 更改为omnibus。现在我编辑了第一篇文章以反映应用程序的当前状态，但仍然出现同样的错误。不知道我做错了什么。包目标仍然不起作用。
好像你的主 pom 中的模块顺序不正确。如果持久性取决于域，它应该出现在它的下方。
@Koby 你确定，父 pom 中模块语句中的顺序很重要吗？我遇到了与问题中描述的相同的问题，但更改顺序不会改变任何内容。
据我所知，父级中的顺序很重要。你遇到了什么错误？ NoClassDefFoundError？你能发布你的maven命令的输出吗？
我假设共享库是您模块的一部分，对吗？如果是这样，您是否尝试在运行 mvn spring-boot:run 之前从根 pom（定义了所有模块）运行 mvn clean install？
