无法在IntelliJ上使用2.2.1.BUILD-SNAPSHOT运行Spring Initializr

2024-04-29 • 问答

试图对我的j2ee进行清理，因此下载了Spring Initializr压缩文件夹并导入IntelliJ。

当我尝试将其作为Java应用程序运行时，出现错误消息。

2019-11-04 12:50:35.702  INFO 5900 --- [           main] com.example.spring.demo.DemoApplication  : Starting DemoApplication on DESKTOP-OPAMEU4 with PID 5900 (C:\JavaWS\demo\demo\target\classes started by hemis in C:\JavaWS\demo\demo)

Process finished with exit code 0

下面是我的pom.xml

有任何线索吗？

鉴于您的项目只是从spring初始化程序生成的，它实际上还没有做任何事情，并且您必须添加一些功能使其不立即退出。

如果您希望它作为Web应用程序启动，则必须添加对spring-boot-starter-web的依赖关系。

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

如果您更喜欢使用tomcat作为容器，则可以采用上述依赖关系，但是如果您更喜欢其他东西-例如jetty，则必须排除tomcat来自spring-boot-starter-web

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

然后，当您开始运行DemoApplication

时，您将获得与此类似的信息。
