java - UnsatisfiedDependencyException：创建名称为“trackiHuntServiceImpl”的 bean 时出错：通过字段“deviceService”表示不满足的依赖关系

Question

我正在使用 Spring v1.4.0.RELEASE。我得到一个异常“org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为'trackiHuntServiceImpl'的bean时出错：通过字段'deviceService'表达的不满足的依赖关系”。它的项目是多模块的。

我列出了主要类代码：

    @Import({PrimaryRepositoryConfig.class, 
    AuditRepositoryConfig.class,
    PaypalConfig.class,
    BraintreeConfig.class,
    CommonConfig.class,
    ElasticsearchConfig.class
})
@ComponentScan(basePackages ={"com.trackimo.server.model" ,
        "com.trackimo.server.dao",
        "com.trackimo.server.services",
        "com.trackimo.server.services.account",
        "com.trackimo.server.services.email",
        "com.trackimo.server.services.common",
        "com.trackimo.server.services.location",
        "com.trackimo.server.services.user",
        "com.trackimo.server.services.trackihunt",
        "com.trackimo.server.services.device",
        "com.trackimo.server.audit.model",
        "com.trackimo.server.audit.dao",
        "com.trackimo.server.utils.converters",
        "com.trackimo.server.worker",
        "com.trackimo.quartz.config"},
        excludeFilters = @ComponentScan.Filter(IgnoreDuringScan.class)
)
@SpringBootApplication(exclude = { DispatcherServletAutoConfiguration.class })
@EnableScheduling
@EnableAsync
public class QuartzApplication {

public static void main(String[] args) {
        SpringApplication.run(QuartzApplication.class, args);
    }

}

Spring 无法创建 bean trackiHuntServiceImpl，因为它无法创建 bean deviceServiceImpl，因为它无法创建 bean emailServiceImpl，因为它依赖于未定义的 DynamicEmailService 类型的 bean eMailMessageSender。

基本上，您必须定义一个 DynamicEmailService 类型的 bean。当您解决此问题时，可能还会缺少其他定义。祝你好运。
