描述：

co.com.coomeva.golden.service.ws.main.GreetingController 中的字段发件人需要找不到类型为“co.com.coomeva.golden.service.ws.jms.DistributorSender”的 bean。注入点有以下注解：- @org.springframework.beans.factory.annotation.Autowired(required=true) 行动：考虑定义一个 'co.com.coomeva.golden.service.ws.jms.DistributorSender 类型的 bean ' 在您的配置中。22:41:15,280 错误 [org.jboss.msc.service.fail] (ServerService 线程池 -- 69) MSC000001: 无法启动服务 jboss.undertow.deployment.default-server.default-host./Golden: org. jboss.msc.service.StartException 在服务 jboss.undertow.deployment.default-server.default-host./Golden: java.lang.RuntimeException: org.springframework.beans.factory.UnsatisfiedDependencyException: 创建名称为“greetingController”的 bean 时出错：通过字段“sender”表示的依赖关系不满足；嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有“co.com.coomeva.golden.service.ws.jms.DistributorSender”类型的合格 bean 可用：预计至少有 1 个有资格作为自动装配候选者的 bean。依赖注释：{@org.springframework.beans.factory.annotation.Autowired(required=true)} at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:84) at java.util.concurrent

我转载了你的问题。以下是您需要进行的更改：@SpringBootApplication(scanBasePackages ={"co.com.coomeva.golden.service.ws.jms","co.com.coomeva.golden.service.ws.main"})您需要使用或DistributorSender之类的注释使您的班级具有弹簧意识。@[e-mail]@SpringBootApplication(scanBasePackages = {"co.com.coomeva.golden.service.ws.jms","co.com.coomeva.golden.service.ws.main"})public class GoldenServiceApplication extends SpringBootServletInitializer&nbsp;{public static void main(String[] args) {&nbsp; &nbsp; SpringApplication.run(applicationClass, args);}@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {&nbsp; &nbsp; return application.sources(applicationClass);}private static Class<GoldenServiceApplication> applicationClass =&nbsp;GoldenServiceApplication.class;}@RestControllerclass GreetingController {@Autowiredprivate DistributorSender sender;@PostMapping("/distributor/records")public GoldenResponse setGoldenRecord(@RequestBody String goldenRecord)&nbsp;{&nbsp; &nbsp; GoldenResponse response = new GoldenResponse();&nbsp; &nbsp; try {&nbsp; &nbsp; &nbsp; &nbsp; sender.publishMessage(goldenRecord);&nbsp; &nbsp; &nbsp; &nbsp; response.setCode(HttpStatus.OK.value());&nbsp; &nbsp; &nbsp; &nbsp; response.setMessage("Golden Record Published");&nbsp; &nbsp; } catch (Exception e) {&nbsp; &nbsp; &nbsp; &nbsp; String error = e.getCause().toString();&nbsp; &nbsp; &nbsp; &nbsp; error = error.length() > 200 ? error.substring(0, 200) : error;&nbsp; &nbsp; &nbsp; &nbsp; response.setMessage("Golden Record was not published.

Answer 2

请删除不必要的注释@ComponentScan，@Configuration和@EnableAutoConfiguration在您有任何特定要求之前，只有下面给定的代码足以运行您的应用程序。@SpringBootApplicationpublic class GoldenServiceApplication extends SpringBootServletInitializer {&nbsp; &nbsp; public static void main(String[] args) {&nbsp; &nbsp; &nbsp; &nbsp; SpringApplication.run(applicationClass, args);&nbsp; &nbsp; }&nbsp; &nbsp; @Override&nbsp; &nbsp; protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {&nbsp; &nbsp; &nbsp; &nbsp; return application.sources(applicationClass);&nbsp; &nbsp; }&nbsp; &nbsp; private static Class<GoldenServiceApplication> applicationClass = GoldenServiceApplication.class;}

Spring-boot 应用程序的一个好习惯：将您的 Application 类（具有@SpringBootApplication注释的类）存储在主包中，并将所有其他*.java文件放在该包下，以便 Spring Application 可以找到它们。
