在IntelliJ中运行Spring Boot导致无法加载'javax.el.E​​xpressionFactory' [英] Running Spring Boot within IntelliJ results in Unable to load 'javax.el.ExpressionFactory'

问题描述

我正在尝试运行一个简单的Spring Boot应用程序，它具有以下Maven pom.file：

I am trying to run a simple Spring Boot application that has the following Maven pom.file:

<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运行应用程序 - jar application.jar ，应用程序正常启动。但是，如果我通过执行主类从IntelliJ运行它，启动失败并出现以下错误：

If I package the file using Maven, and run the application through java -jar application.jar, the application starts up normally. However, if I run it from IntelliJ by executing the main class, the startup fails with the following error:

有没有人能够直接从IntelliJ运行Spring Boot应用程序？

Has anyone been able to run a Spring Boot application directly from IntelliJ?

推荐答案

问题可能是EL实现位于您标记为已提供的Tomcat启动器中。如果没有提供（它不适用于JAR文件）也许你应该把它留下来？

The problem is probably that the EL implementation is in the Tomcat starter that you marked as "provided". If it isn't provided (which it won't be for a JAR file) maybe you should just leave it out?
