SpringBoot - making jar files - No auto configuration classes found in META-INF/spring.factories

It looks like it doesn't found auto configuration classes in META-INF/spring.factories. How to add it, and what should be the content of this file?
看起来它在META-INF/spring.factories. 如何添加，这个文件的内容应该是什么？
回答by Benoit Larochelle
I had the same problem and just solved it.
我有同样的问题，刚刚解决了它。
At first, I was generating the fat jar with the maven-assembly-plugin, which created a file called mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar. This file gave the same problem as you mentioned when I tried running it.
起初，我用 生成了胖 jar maven-assembly-plugin，它创建了一个名为mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar. 当我尝试运行该文件时，该文件出现了与您提到的相同的问题。
I think that because it's a Spring Boot application, you need to use their plug-in. I changed my packaging to the spring-boot-maven-pluginand it generates two files: mavenproject1-0.0.1-SNAPSHOT.jarand mavenproject1-0.0.1-SNAPSHOT.jar.original. Just try java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar, and it will hopefully work. :-)
我认为因为它是一个Spring Boot应用程序，您需要使用他们的插件。我将包装更改为spring-boot-maven-plugin，它生成两个文件：mavenproject1-0.0.1-SNAPSHOT.jar和mavenproject1-0.0.1-SNAPSHOT.jar.original. 试试吧java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar，它有望奏效。:-)

This configuration works for me. I execute my JAR as a service but the line is:
这个配置对我有用。我将 JAR 作为服务执行，但该行是：
javaw -jar MY_JAR.jar
POM:

</properties>
...

With Spring Boot, it is no longer necessary to use the assembly-plugin. Do not forget to call the packagegoal.
使用 Spring Boot，不再需要使用 assembly-plugin。不要忘记调用包目标。
Here is the documentation example.

Caused by: java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.
From above it seems that your packageing is not properly done. I know I'm late but it might help someone else.
从上面看来，您的包装没有正确完成。我知道我迟到了，但它可能会帮助别人。

解决方案
Please check your @SpringBootApplicationclass shoud have base package all above the other classes. For example, let's your class @SpringBootApplicationis inside a package com.sb.foothen all other spring stereotype classes should goes inside com.sb.foo.xxxwhere xxxcan be anything. It can be further sub package com.sb.foo.xxx.yyy. This is a functionality of SpringBoot to enable Auto Configuration. This auto configuration works fine with IDE's like Intellijor Eclipseeven if you have made the mistake.
请检查您的@SpringBootApplication班级是否应具有高于其他班级的基础包。例如，让你的类@SpringBootApplication在一个包中，com.sb.foo然后所有其他 spring 构造型类应该放在里面com.sb.foo.xxx，xxx可以是任何东西。它可以进一步分包com.sb.foo.xxx.yyy。这是 SpringBoot 的一项功能，用于启用自动配置。这种自动配置适用于 IDE 之类的Intellij，Eclipse即使您犯了错误。
The chances of facing such problem will be more if you're not using any building tool or recommeded IDEs like STS eclipsefor development.
如果您不使用任何构建工具或推荐的 IDESTS eclipse来进行开发，那么遇到此类问题的机会会更多。

Alternatively, if you cannot use the spring boot plugin for whatever reason, you can include the following file in your application. It should be called src/main/resources/META-INF/spring.factories:
或者，如果由于某种原因您无法使用 spring boot 插件，您可以在您的应用程序中包含以下文件。它应该被称为src/main/resources/META-INF/spring.factories：
This will work for spring boot 1.x and is helpful if you want to use spring managed beans in a REPL.
这将适用于 spring boot 1.x，如果您想在 REPL 中使用 spring 管理的 bean，这将很有帮助。
回答by Andy
spring.factories is loaded by the AutoConfigurationImportSelector class in spring-boot-autoconfigure. This walks the context classloader for all resources of type META-INF/spring.factories.
spring.factories 由 spring-boot-autoconfigure 中的 AutoConfigurationImportSelector 类加载。这将遍历 META-INF/spring.factories 类型的所有资源的上下文类加载器。
To get spring boot to work after shading the jar, I simulated the same by merging the contents of all available spring.factories files into a single spring.factories file in my own jar's META-INF folder.
为了在对 jar 着色后使 spring boot 工作，我通过将所有可用 spring.factories 文件的内容合并到我自己的 jar 的 META-INF 文件夹中的单个 spring.factories 文件来模拟相同的操作。

我遇到了同样的问题：
IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories.
with Java 9, spring boot 2.0.0, springboot-javafx-support 2.1.6. I tried both maven and gradle 4 on the same project.
使用 Java 9，spring boot 2.0.0，springboot-javafx-support 2.1.6。我在同一个项目中尝试了 maven 和 gradle 4。

You could add the spring.factories file to your META-INF folder. The spring.factories file for Spring version 2.0.4 is located here: https://github.com/spring-projects/spring-boot/blob/v2.0.4.RELEASE/spring-boot-project/spring-boot-autoconfigure/src/main/resources/META-INF/spring.factories
您可以将 spring.factories 文件添加到您的 META-INF 文件夹中。Spring 2.0.4 版的 spring.factories 文件位于：https: //github.com/spring-projects/spring-boot/blob/v2.0.4.RELEASE/spring-boot-project/spring-boot-autoconfigure /src/main/resources/META-INF/spring.factories
