Maven Spring Boot插件：如何从另一个项目运行spring boot

我不认为可以使用 spring-boot-maven-plugin ，因为 start 目标似乎没有给你一个解决方案来解决本地存储库或Maven反应堆，这可能是你想要的。您尝试过的项目配置属性并非旨在以这种方式覆盖。应仅使用插件目标中列出的属性配置插件执行 docs 。

I don't think it's possible to run integration tests against another module using spring-boot-maven-plugin, because the start goal doesn't seem to give you a means to resolve the application from the local repository or the Maven reactor, which is probably what you want. The project configuration property you've tried isn't designed to be overriden that way. Plugin executions should be configured using only the properties listed in the plugin goal docs.

相反，我认为你至少有两种可能的方法：

Instead I think you've got at least two possible approaches:

1. 使用其他插件来控制服务器;或


2. 直接从代码中的测试运行服务器。

选项1

为此，我认为你需要一种方法来复制你想要运行的服务器工件，以及一些更通用的启动和停止它的方法，比如 cargo-maven2-plugin 或 process-exec-maven-plugin 。

只需配置 repackage 服务器工件构建中的目标：

Just configure the repackage goal in the server artifact build:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <excludeDevtools>true</excludeDevtools>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>

然后从集成测试模块中，您可以执行以下操作：

Then from the integration tests module, you could do something like:

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-server-artifact</id>
            <goals>
                <goal>copy</goal>
            </goals>
            <phase>pre-integration-test</phase>
            <configuration>
                <artifactItems>
                    <artifactItem>
                        <groupId>${project.groupId}</groupId>
                        <artifactId>SpringBoot2App</artifactId>
                        <version>${project.version}</version>
                        <classifier>jar</classifier>
                        <outputDirectory>${project.build.directory}</outputDirectory>
                        <destFileName>app.jar</destFileName>
                    </artifactItem>
                </artifactItems>
            </configuration>
        </execution>
    </executions>
</plugin>

<plugin>
    <groupId>com.bazaarvoice.maven.plugins</groupId>
    <artifactId>process-exec-maven-plugin</artifactId>
    <version>0.7</version>
    <executions>
        <execution>
            <id>start-server</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>start</goal>
            </goals>
            <configuration>
                <name>run-server</name>
                <waitForInterrupt>false</waitForInterrupt>
                <healthcheckUrl>http://localhost:8080</healthcheckUrl>
                <arguments>
                    <argument>java</argument>
                    <argument>-jar</argument>
                    <argument>${project.build.directory}/app.jar</argument>
                </arguments>
            </configuration>
        </execution>

        <execution>
            <id>stop-server</id>
            <phase>post-integration-test</phase>
            <goals>
                <goal>stop-all</goal>
            </goals>
        </execution>
    </executions>
</plugin>

选项2

只需申报正常Maven依赖于测试工件中的服务器工件，并在挂钩之前在JUnit中运行服务器的 @SpringBootApplication 类，或者你有什么，例如

Option 2

Just declare a normal Maven dependency on the server artifact from the test artifact, and run the server's @SpringBootApplication class in a JUnit before hook or what have you, e.g.

private static ConfigurableApplicationContext context;

@BeforeClass
public static void setUp() {
    context = new SpringApplicationBuilder(SimpleServiceApplication.class).run();
}

@AfterClass
public static void tearDown() {
    if (context != null) {
        context.close();
    }
}

这可能足以满足您的需求。

This may be sufficient for your needs.
