使用Maven程序插件在META-INF / spring.factories中找不到自动配置类

标签： java spring spring-boot

我正在使用下面的maven程序集插件来打包spring boot应用程序。我正在使用此插件，因为spring-boot-maven插件还有其他问题。

    <plugin>
                <artifactId>maven-assembly-plugin</artifactId>

                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>com.gcc.news.publishing.Application</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase> 
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

当我使用

运行它时 
java -Dspring.profiles.active=dev -jar target/gcc-news-publishing-service-0.0.1-SNAPSHOT-jar-with-dependencies.jar.

我正处于例外之下。

当我手动编辑打包的jar中的META-INF / spring.factories文件并将其内容替换为下面的内容时，它运行良好，没有任何问题。请帮助我如何确保手动放置在spring.factories文件中的内容自动进入同一文件，而无需手动编辑jar文件。

我已手动将内容放入打包的jar中的spring.factories文件中

注意：我已经尝试在/src/main/resources/META-INF/spring.factories中分配内容，但是打包jar文件时，它不会被spring boot启动。

答案 0 :(得分：1)

您必须显式添加转换器以添加spring.factories内容

<configuration>
<transformers>
    <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
        <resource>META-INF/spring.factories</resource>
    </transformer>
</transformers>
</configuration>

请参阅How to create spring-based executable jar with maven?

或者，您也可以使用spring-boot自定义布局来打包应用程序
