java - 在IntelliJ中运行Spring Boot导致无法加载 'javax.el.ExpressionFactory'

我正在尝试运行一个具有以下Maven pom.file的简单Spring Boot应用程序:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <start-class>com.ptkonline.EwsdProxyApplication</start-class>
    <java.version>1.8</java.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

如果我使用Maven打包文件，并通过java -jar application.jar运行该应用程序，则该应用程序将正常启动。但是，如果我通过执行主类从IntelliJ运行它，则启动失败并显示以下错误:

有没有人能够直接从IntelliJ运行Spring Boot应用程序？

最佳答案

问题可能是EL实现在您标记为“提供”的Tomcat启动器中。如果未提供(JAR文件不会提供)，也许您应该将其保留？
