Spring-Boot Executable-Jar NoSuchBeanDefinitionException [英] Spring-Boot Executable-Jar NoSuchBeanDefinitionException

问题描述

我有一个使用 Spring-Boot 创建的应用程序.

I have an application created using Spring-Boot.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.1.8.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

并将我的 Appplication.java 注释如下.

And have my Appplication.java annotated as shown below.

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application

public static void main(String[] args) {
    final ConfigurableApplicationContext context = SpringApplication.run(Application.class);
...

当我在 eclipse 中运行它时它没有任何问题，但是当我生成一个可执行的 jar 时它会抛出异常

This works when I run it inside eclipse without any problems but, when I generate an executable jar it throws the exception

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No    qualifying bean of type [com.company.engine.services.BaseDao] is defined
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:319)
    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:987)

有什么想法吗?

来自@Oleg Majewski 的解决方案，稍作修改:

<build>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <version>1.1.8.RELEASE</version>
      <configuration>
        <mainClass>com.company.engine.Application</mainClass>
        <layout>ZIP</layout>
      </configuration>
      <executions>
        <execution>
          <goals>
          <goal>repackage</goal>
          </goals>

推荐答案

你可以尝试使用 spring-boot-maven-plugin 而不是自己做 maven-assembly-plugin 和 maven-dependency-plugin :

You can try to use spring-boot-maven-plugin instead of doing maven-assembly-plugin and maven-dependency-plugin by yourself:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>1.1.8.RELEASE</version>
    <executions>
        <execution>
             <goals>
                <goal>repackage</goal>
             </goals>
        </execution>
    </executions>
</plugin>

在你可以像这样构建 jar 之后:

After you can build the jar like this:

$ mvn package
$ ls target/*.jar
