更新：奇怪的是，仅当我使用Gradle构建jar时才会引发此错误。Maven生成的jar运行良好！因此，我目前正在研究gradle构建脚本/ spring boot配置是否以及如何失败。
我有一个Spring Boot应用程序抛出以下错误

初始化器：
@Configuration @ComponentScan(basePackages={"com.mycompany", "com.mycompany.utils", "com.mycompany.domain","com.mycompany.resources", "com.mycompany.resources.hook"}) @EnableAutoConfiguration public class Initializer { public static void main(String[] args) { SpringApplication.run(Initializer.class, args); } }
配置类
@Configuration @EnableAsync @EnableScheduling @PropertySource("classpath:application-dev.properties") @ImportResource(value="classpath:applicationContext.xml") @ComponentScan(basePackages={ "com.mycompany.web"}) public class StatusConfiguration { @Autowired Environment env; @Bean public ObjectMapper jacksonObjectMapper() { return new CustomObjectMapper(); } @Bean public TargetServer targetServer(){ TargetServer targetServer = new TargetServer(); targetServer.setJndiValidationConnectionURL(env.getProperty("jndiValidationConnectionURL")); targetServer.setJndiValidationUsername(env.getProperty("jndiValidationUsername")); targetServer.setJndiValidationPassword(env.getProperty("jndiValidationPassword")); return targetServer; } }
控制者
@RestController public class StatusController { @Autowired private ReportService reportService; @Autowired private TargetServer targetServer; private Logger log = LoggerFactory.getLogger(StatusController.class); @RequestMapping(value = "/report") public MyReport getStatus(){ MyReport report = reportService.getReport(); return report; } @RequestMapping(value = "/report/no-cache") public MyReport getStatusNoCache(){ autoRunReport(); MyReport report = reportService.getReport(); return report; } @Scheduled(fixedDelay=300000) public void autoRunReport(){ reportService.kickOffReport(targetServer); log.debug("Running the scheduled validation Report!"); } }
Gradle配置
apply plugin: 'java' apply plugin: 'maven' apply plugin: 'spring-boot' dependencies { compile("org.springframework.boot:spring-boot-starter-web:1.1.6.RELEASE") compile(group: 'org.ihc.mh', name: 'mh-util', version:'13.12.5') { exclude(module: 'slf4j-api') exclude(module: 'slf4j-log4j12') } /* testCompile(group: 'org.springframework.boot', name: 'spring-boot-starter-test', version:'1.1.6.RELEASE') { exclude(module: 'commons-logging') }*/ } buildscript { dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:1.1.6.RELEASE") } } /* idea { module { inheritOutputDirs = false outputDir = file("$buildDir/classes/main/") } }*/
另外，如果我直接运行Initializer（作为Java可执行类），则运行良好。但是，当我将其打包为jar并运行jar文件时，此操作将失败。任何帮助/见解表示赞赏。

我们（Spring Boot团队）之前已经看到过这种问题。不幸的是，JVM的诊断确实很差。它试图告诉您的是，它遇到了一个带有Class []属性的注释，该注释引用的类不在classpath上。如果它告诉您缺少的课程是什么，那将是非常有用的。
我尝试使用上面的代码片段重现您的失败，但是无法这样做。在使用Maven进行此工作时，请尝试查看unzip -l使用Maven和Gradle构建的jar的运行输出，看看是否可以发现Gradle案例中缺少的内容。
unzip -l
