SpringBoot - 制作jar文件 - 在META-INF / spring.factories中找不到自动配置类

时间:2016-08-05 14:45:23

标签: java spring intellij-idea spring-boot

使用Intellij启动应用程序时,一切正常。但是当我做了fatJar并执行时:

java -jar myapp.jar

我明白了:

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?

我遇到了同样的问题并且解决了它。

起初我使用maven-assembly-plugin生成胖罐,它创建了一个名为mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar的文件。当我尝试运行它时,此文件会出现与您相同的问题。

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。我将包装更改为spring-boot-maven-plugin,并创建了两个文件:mavenproject1-0.0.1-SNAPSHOT.jarmavenproject1-0.0.1-SNAPSHOT.jar.original。只需尝试java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar即可。 : - )

供参考,这是我的pom.xml:

答案 1 :(得分:9)

此配置适合我。我将JAR作为服务执行,但行是:

javaw -jar MY_JAR.jar

<强> POM

<properties>
        <!-- Spring boot main class -->
        <start-class>com.PATH_TO_MAIN.Main</start-class>
</properties>
...
<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

使用Spring-boot不再需要使用assembly-plugin。不要忘记致电打包目标

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

答案 2 :(得分:9)

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 bean,这将非常有用。

答案 3 :(得分:4)

这是解决方案:

  1. 仅在POM.xml中添加插件

    <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>
                  </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
    

  2. pom.xml中的一个属性

    <properties>
      <start-class>com.xxx.yyy.MainClass</start-class>
    </properties>
    
  3. 运行命令

    mvn clean package spring-boot:repackage
    
  4. 现在运行您在目标文件夹中创建的jar(现在包括所有依赖项)

    java -jar my-service-0.0.1-SNAPSHOT.jar
    

答案 4 :(得分:3)

我已将此配置添加到我的pom中,问题已解决。

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.5.2.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>

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.

从上面看,您的打包似乎没有正确完成。我知道我迟到了,但可能对其他人有帮助。

<强>解决方案

请检查您的@SpringBootApplication课程,并在其他课程之上提供基础课程。例如,假设您的班级@SpringBootApplication位于包com.sb.foo内,那么所有其他春天刻板印象类应该位于com.sb.foo.xxx里面xxx可以是任何东西。它可以是进一步的子包com.sb.foo.xxx.yyy。这是SpringBoot的一项功能,可以启用自动配置。即使您犯了错误,此自动配置也适用于IntellijEclipse等IDE。

如果您没有使用任何构建工具或推荐像STS eclipse这样的IDE进行开发,那么面临此类问题的可能性会更大。

对于我们这些不熟悉 IntelliJ、Spring 和 Maven 的人:

如果您想在 IntelliJ 中构建一个 jar,您可能正在使用 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 - 为您构建它。为此,您需要在 IntelliJ 中调出 Maven 面板(在 View => Tool Windows => Maven 底部),然后双击“package”。瞧!

答案 7 :(得分:0)

spring.factories由spring-boot-autoconfigure中的AutoConfigurationImportSelector类加载。这将为META-INF / spring.factories类型的所有资源遍历上下文类加载器。

为了在对jar进行着色后使spring启动工作,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文件中来模拟相同的内容。

我遇到了同样的问题:

IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories.

使用Java 9,spring boot 2.0.0,springboot-javafx-support 2.1.6。 我在同一个项目上尝试了maven和gradle 4。

对我来说,解决方法是使用java 8打包jar。

您可以将spring.factories文件添加到META-INF文件夹中。 Spring版本2.0.4的spring.factories文件位于以下位置: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

此错误是因为您正在通过eclipse导出jar。 解决方法:mvn clean install之后,仅使用目标文件夹中生成的jar

答案 13 :(得分:0)

下面的 POM 对我有用,这将允许您拥有包含所有依赖项的组装包。

在 POM 的开头添加这个

<modelVersion>4.0.0</modelVersion>
<groupId>com.xyz.test</groupId>
<artifactId>test</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>test</name>
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.5.3</version>
</parent>

添加这个插件

           <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
                <mainClass>com.xyz.test</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

运行命令

  1. 要检查运行 - mvn spring-boot:run
  2. 制作脂肪罐 - mvn clean package
  3. 运行 jar - java -jar /target/jar-file-name.jar

答案 14 :(得分:-1)

或者,使用eclipse IDE运行创建jar文件
