使用Maven多模块项目进行Spring Boot [英] Spring boot with maven multi module project

问题描述

我有一个Maven多模块项目，其设计类似于以下SO帖子中的第一个答案: 带有Spring Boot的多模块Maven

I have a maven multi module project designed like the first answer in following SO post: Multi-module maven with Spring Boot

现在，我需要一个通用的Maven模块，其中可以包含多个微服务要使用的模型.如果我将这个公共项目作为一级父pom的子项进行创建(这样，由启动注入的所有依赖项(例如jpa，jackson等)都可以使用)，那么STS/Spring会将其检测为启动应用程序，并且抱怨没有Main关于Maven构建的课程.

Now I want a common maven module that can contain some models to be used by multiple microservices. If I make this common project as a child of the first level parent pom (so that all dependencies injected by boot like jpa, jackson etc are available to common), then STS/Spring is detecting it as a boot application and complains about no Main class on maven build.

有人可以建议我如何实现这一目标吗?

Can someone suggest how I can achieve this?

当前代码:

父pom.xml:(仅包括相关部分)

parent pom.xml: (Only relevant parts included)

<project>
<name>...</name>
<groupId>...</groupId>
<artifactId>...</artifactId>
<packaging>pom</packaging>
<version>...</version>
<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Brixton.M3</version>
    <relativePath />
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
    </dependency>
</dependencies>
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
</project>

子(公共模块)pom.xml(仅相关部分)，而不是引导应用程序:

child (common module) pom.xml (only relevant parts), not to be boot app:

<project>
<artifactId>...</artifactId>
<version>...</version>
<name>...</name>

<parent>
    <groupId>...</groupId>
    <artifactId>...</artifactId>
    <version>...</version>
</parent>

</project>

推荐答案

我没有关于您的项目的所有详细信息，但我最好的猜测是spring-boot-maven-plugin是在父项上定义的(或者您正在使用spring-boot-starter-parent在您的根pom中).这有效地要求构建将模块打包为Spring Boot应用程序(这不是您想要的).

I don't have all the details regarding your project but my best guess is that the spring-boot-maven-plugin is defined on the parent (or you are using the spring-boot-starter-parent in your root pom). This effectively ask the build to package your module as a Spring Boot app (which is not what you want).

STS可能会寻找该提示，以找出模块是否包含Spring Boot应用程序.如果它寻找带有@EnableAutoConfiguration(或SpringBootApplication)注释的主类，也许会更好.

STS probably looks for that hint to figure out if a module contains a Spring Boot application or not. Maybe it would be nicer if it looks for a main class annotated with @EnableAutoConfiguration (or SpringBootApplication).

通过指定如果STS仍将模块作为Spring Boot应用程序使用，我将在其跟踪器中创建问题

If STS still picks up the module as a Spring Boot app, I'd create an issue in their tracker
