看起来它没有在META-INF/spring.factories中找到自动配置类.如何添加此文件？这个文件的内容应该是什么？

Answer 1

小智 57

我有同样的问题,只是解决了它.

起初我用它生成了胖罐maven-assembly-plugin,它创建了一个名为的文件mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar.当我尝试运行它时,此文件提供了与您相同的问题.

我认为因为它是一个Spring Boot应用程序,所以你需要使用它们的插件.我将包装改为了spring-boot-maven-plugin,它创建了两个文件:mavenproject1-0.0.1-SNAPSHOT.jar和mavenproject1-0.0.1-SNAPSHOT.jar.original.只是尝试java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar,它将有希望工作.:-)

作为参考,这是我的pom.xml:

值得注意的是，pom.xml中的<packaging> jar </ packaging>是必要的。没有它，您仍然可以在IDE中运行该应用程序，但是.jar将不起作用。 (2认同)
进行这些更改后,您使用的构建命令是什么？mvn干净安装？mvn包？或者是其他东西？ (2认同)
如果我不能使用“ spring-boot-starter-parent”作为父母怎么办？ (2认同)
此处使用的构建命令： mvn clean package spring-boot:repackage (2认同)

这是解决方案：

在 POM.xml 中只添加插件

<build>
<plugins>
   <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>
            <fork>true</fork>
            <mainClass>${start-class}</mainClass>
        </configuration>
          <executions>
            <execution>
              <goals>
                <goal>repackage</goal>

对于刚接触 IntelliJ、Spring 和 Maven 的人来说：

如果您想在 IntelliJ 中构建 jar，您很可能正在使用 IntelliJ 的构建系统：构建、构建工件等。但是，这不是 Maven。您需要的是 Maven（而不是 IntelliJ）来为您构建它。为此，您需要在 IntelliJ 中打开 Maven 面板（在 View => Tool Windows => Maven 下），然后双击“package”。瞧！

这个配置适合我.我执行我的JAR作为服务但行是:

使用Spring-boot不再需要使用assembly-plugin.别忘了打电话给包目标

您可以看到文档示例:http://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html

如果spring应用程序只是另一个独立jar中的另一个依赖项,那么这似乎不起作用. (2认同)

Answer 5

csc*_*can 11

或者,如果由于某种原因无法使用spring boot插件,则可以在应用程序中包含以下文件.它应该被称为src/main/resources/META-INF/spring.factories:

https://github.com/spring-projects/spring-boot/blob/1.5.x/spring-boot-autoconfigure/src/main/resources/META-INF/spring.factories

这适用于spring boot 1.x,如果你想在REPL中使用spring managed beans,这将非常有用.

该文件的新位置在https://github.com/spring-projects/spring-boot/blob/2.1.x/spring-boot-project/spring-boot-autoconfigure/src/main/resources/META-INF /spring.factories (2认同)

我在pom中添加了此配置，问题已解决：

<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
