为什么当IntelliJ run不能正常工作时，我可以使用mvn spring-boot:run启动我的应用程序? [英] Why can I start my application using mvn spring-boot:run while IntelliJ run doen´t work?

问题描述

当我使用命令mvn spring-boot:run时，项目将编译并完美启动.但是，当我在IDE(IntelliJ)中使用播放按钮时，出现以下错误:

When I use the command mvn spring-boot:run the project compiles and starts perfectly. However, when I use the play-button in my IDE (IntelliJ), I get the following error:

Description:
Parameter 3 of constructor in com.example.module.services.PdfService required a bean of type 'org.springframework.mail.javamail.JavaMailSender' that could not be found. 

这可能是什么原因?我很想使用IDE提供的调试和开发工具.

What might be the reason for this? I`d love to use the debugging and dev tools provided by the IDE.

我尝试过的事情:

• 选择构建"->重建项目"
• 点击文件>使缓存无效/重新启动
• mvn clean->建立->制作项目
• Maven->重新导入
• 检查首选项" |不存在"中的排除项构建，执行，部署|编译器排除

我的pom.xml

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

发生错误的服务

@Service
public class PdfService {

private final Logger logger = LoggerFactory.getLogger(PdfService.class);

private PdfCreator pdfCreator;

private ConfigProperties properties;

private ReceiptService receiptService;

private JavaMailSender javaMailSender;

private MessageSourceAccessor messageSourceAccessor;

@Autowired
public PdfService(PdfCreator pdfCreator,
                  ConfigProperties properties,
                  ReceiptService receiptService,
                  JavaMailSender javaMailSender,
                  MessageSourceAccessor messageSourceAccessor) {
    this.pdfCreator = pdfCreator;
    this.properties = properties;
    this.receiptService = receiptService;
    this.javaMailSender = javaMailSender;
    this.messageSourceAccessor = messageSourceAccessor;
}

非常感谢您的帮助.
