Question

我用Spring Boot编写了最简单的hello world项目。也就是说，当您在浏览器中打开localhost：8080时，将看到单词“ hello world”。我刚刚发现，如果使用Intellij Community运行该项目，则IDE可以启动该项目，并且可以在浏览器中打开localhost：8080。但是，如果我在Intellij Ultimate中运行相同的项目，则会引发错误。

我使用的是完全相同的pom.xml。这两个IDE之间有什么区别？

<?xml version="1.0" encoding="UTF-8"?>

谢谢大家的评论和回答。我忘了提到我所做的一些努力。根据一些研究，例如this stackflow question的回答，我试图像这样在我的pom.xml文件中排除Intellij Ultimate中的LoggerFactory错误：

<exclusion>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-logging</artifactId>
</exclusion>

然后Intellij Ultimate给我另一个错误，然后Intellij Community可以通过单击“运行”按钮来完美地启动项目：

我不确定是否通过使用完全相同的项目，为什么一个IDE可以完美地工作，而另一个IDE却总是给我错误？

Answer 1

尝试像这样修改和修改pom.xml中的依赖项

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

编辑* ，如果要登录，则可以使用此依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

Answer 2

感谢所有评论并再次答复。经过相当多的努力来研究问题，我终于找到了解决方案。原来，SDK设置有些不同。关于SFL4J的评论使我深受鼓舞。

首先，我打开文件->项目结构->项目设置->项目，以检查用于运行该项目的SDK名称。

第二，在相同的“项目结构”窗口中，切换到“平台设置”->“ SDK”，然后单击我用来运行该项目的SDK。

即使在两个IDE中，我的SDK都设置为相同的JDK主目录路径（即JAVA_HOME），由于某些原因，两个IDE之间的.jar列表不同。 Ultimate IDE中的列表比Community IDE中的列表长。作为Java新手，我无法说出列表不同的确切原因。我最好的猜测是，社区IDE是在安装Java之后立即安装的，而Ultimate IDE是在我用Java运行某些东西后几个月安装的。我通过在社区IDE中创建另一个SDK（具有与Ultimate IDE中相同的.jar列表）来验证这一点，然后单击“运行”。现在，社区IDE中的项目出现了与我在遇到Ultimate IDE时遇到的问题相同的错误。

作为解决方案，我从Intellij Ultimate中的SDK中删除了多余的.jar文件。运行良好。无需在pom.xml中添加排除项。我正在发布.jar文件的原始列表，以供您参考。

没有引发错误的Intellij社区SDK：

和给我LoggerFactory错误的Intellij Ultimate SDK：

接下来我要研究的是那些删除的额外.jar文件对运行Spring Boot的影响。我想知道哪些.jar文件/依赖项完全影响Spring Boot的运行。

Intellij运行相同的Spring Boot项目，社区版本运行良好，但终极版本引发错误
