java.lang.NoClassDefFoundError:javax/servlet/ServletContext

use*_*875 12 java intellij-idea spring-boot

我刚刚从14.1升级到IntelliJ 15.0(我很着急 在此输入图像描述忘了保存14.1的先前插件状态,并且我正在尝试使用Gradle在Intellij中使用Spring Boot配置常规运行/调试配置设置.在配置选项卡中,我添加了1)Main类,2)JRE,以及3)IntelliJ中模块的类路径.我使用Spring Boot作为选定的配置.但是,当选择Run I时会收到以下错误:

有同样的问题.看起来特定于尝试通过IntelliJ 15.x spring boot运行配置运行spring boot web应用程序.因为我使用的是mavenI而是创建了一个maven指定command line actionas 的运行配置spring-boot:run- 这在运行和调试模式下都有效.附上截图.

有同样的问题，通过修复 pom.xml 中更改的 pom.xml 来修复它：

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

将其更改为：

        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>compile</scope>
    </dependency>

这解决了问题:)

好的，这是我必须做的来解决这个特定问题：

  1. IntelliJ 需要在调试/运行配置中定义名为 bootRun 的 Gradle 任务。这使我现在可以在 IntelliJ 中运行后端代码或调试后端代码更新。
  1. 接下来，我必须重组我的 IntelliJ 目录，因为 IntelliJ 15 同时安装了父 JRE 文件夹和子 JRE 文件夹，这是不正确的，因此 IntelliJ 显示并出现异常，指出它找不到 a) java.exec 或 b) jvm.cfg 文件在它的 JRE/Lib 子目录下。

一旦我解决了这两个问题，构建和调试似乎都适用于 Java Spring 后端。我向 IntelliJ 跟进了奇怪的 JRE 安装。
