为什么我可以使用mvn spring boot:run启动我的应用程序，而IntelliJ run不起作用？

Question

当我使用命令mvn spring-boot:run时，项目可以完美地编译和启动。但是，当我在IDE (IntelliJ)中使用play按钮时，我得到以下错误:

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？我喜欢使用IDE提供的调试和开发工具。

我试过的是：

• 选择构建-

我的pom.xml

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

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;
}

非常感谢帮助。

Answer 1

您需要创建配置类，并告诉它们使用我刚才尝试过的＜code＞@Bean

@Configuration
public class AppConfiguration {

    @Bean
    public JavaMailSender javaMailSender(){
        return new JavaMailSenderImpl();
    }

}

Answer 2

您需要添加＜code＞org.springframework.mail.javamail.JavaMailSender。jar作为依赖项，因为它丢失了。您可以按照以下步骤在intellij中进行修复。

< li >下载jar文件。 < li >在IntelliJ Idea IDE中，转到文件

现在，它会被修复。
