Question

使用java -jar命令运行Spring Boot Jersey应用程序时遇到问题。当我从IntelliJ运行主类时它工作得很好。我因此认为这可能是一个类路径问题，但我使用了maven-assembly-plugin，并且所有的Spring类似乎都在那里。

我有：类路径上的spring-boot-starter-web，spring-boot-jersey，spring-boot-starter-tomcat以及Spring引导的其余部分我已经包含了这个：

    <dependency>
        <!-- Import dependency management from Spring Boot -->
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>1.1.8.RELEASE</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>

我的程序集插件配置如下：

            <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.5</version>
            <!-- nothing here -->
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4.1</version>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <mainClass>org.online.auth.conf.ApplicationMain</mainClass>
                    </manifest>
                </archive>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

当我解压缩jar文件时，我发现所有Spring依赖项都存在（EmbeddedServletContainer及它的子类（Tomcat / Jetty））。

启动日志显示以下错误消息：

:: Spring Boot ::

我试图明确定义一个EmbeddedServletContainerFactory，但这只是给了我另一个例外，其中有一条消息说A ServletContext is required to configure default servlet handling。

对此问题的任何帮助将不胜感激！

编辑！

我尝试通过实现BeanPostProcessor来打印容器创建的每个bean：

@ComponentScan
@EnableAutoConfiguration(exclude = {
    DataSourceAutoConfiguration.class,
    DataSourceInitializer.class,
    DataSourceTransactionManagerAutoConfiguration.class,
    SecurityAutoConfiguration.class})
 public class ApplicationMain extends SpringBootServletInitializer implements BeanPostProcessor     {

public static void main(String[] args) {
    ConfigurableApplicationContext context = SpringApplication.run(ApplicationMain.class, args);
}

@Override
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
    System.out.println("\t\tbean: "+ beanName);
    return bean;
}

}

在IntelliJ中运行它会给我以下输出：

2014-11-03 16:11:26.348  INFO 13548 --- [           main] trationDelegate$BeanPostProcessorChecker : Bean 'metaDataSourceAdvisor' of type [class org.springframework.security.access.intercept.aopalliance.MethodSecurityMetadataSourceAdvisor] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

使用java命令运行jar文件会给出以下输出：

2014-11-03 16:01:36.302  INFO 6704 --- [           main]   trationDelegate$BeanPostProcessorChecker : Bean 'metaDataSourceAdvisor' of type [class org.springframework.security.access.intercept.aopalliance.MethodSecurityMetadataSourceAdvisor] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

非常感谢任何帮助！

在我更彻底地阅读文档之后，我终于明白了。 Spring docs明确指出您需要在pom.xml的build部分中使用spring-boot-maven-plugin。

<build>
    <plugins>
       <plugin>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-maven-plugin</artifactId>
       </plugin>
    </plugins>
</build>

我还添加了一个声明main-class的属性：

<properties>
   <start-class>org.online.auth.ApplicationMain</start-class>
</properties>

希望这对其他人有帮助。
