자바 langNoClassDefFFoundError: javax/servlet/ServletContext

방금 14.1에서 IntelliJ 15.0으로 업그레이드했는데(급해서 이전 플러그 상태를 14.1에 저장하는 것을 잊었습니다), Gradle을 사용하여 Intellij에서 Spring Boot로 일반적인 run/debug 구성 설정을 구성하려고 합니다.Configuration 탭에서 1) Main 클래스, 2) JRE, 3) IntelliJ 모듈의 클래스 경로를 추가했습니다.선택한 구성으로 Spring Boot을 사용합니다.그러나 실행을 선택하면 다음 오류가 발생합니다.

같은 문제가 있었습니다.IntelliJ 15.x를 통해 스프링 부트 웹 앱을 실행하는 것에 특정한 것 같습니다.spring boot설정을 실행제가 사용을.maven저는 대신에.mavenrun configuration 지정command line action~하듯이spring-boot:run- 실행 모드와 디버그 모드에서 모두 작동합니다.스크린샷 첨부.

동일한 문제가 발생하여 pom.xml에서 변경된 pom.xml을 수정하여 수정하였습니다.

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

다음으로 변경:

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

이것으로 문제가 해결되었습니다 :)

스프링부트 템플릿이 없는 Community Edition을 사용할 때도 동일한 문제가 있었습니다.

구성 편집...에서 문제를 해결할 수 있습니다.-> 옵션 수정 -> Java 확인:"제공" 범위에 종속성 포함

이 특정 문제를 해결하기 위해 제가 해야 할 일은 다음과 같습니다.

1. IntelliJ는 Debug/Run Configuration 내에서 bootRun이라는 Gradle Task에 대한 정의가 필요했습니다.이제 IntelliJ에서 백엔드 코드를 실행하거나 백엔드 코드 업데이트를 디버그할 수 있습니다.

2. 다음으로 IntelliJ 15가 상위와 하위 JRE 폴더를 모두 설치했기 때문에 IntelliJ 디렉토리를 재구성해야 했습니다. 따라서 IntelliJ는 JRE/Lib 하위 디렉토리 아래에 a) java.exec 또는 b) jvm.cfg 파일을 찾을 수 없다는 예외를 표시했습니다.

이 두 가지 문제를 해결하자 빌드와 디버깅 모두 Java Spring 백엔드에 적합한 것 같습니다.저는 특이한 JRE 설치에 대해 IntelliJ와 후속 조치를 취했습니다.

당신의 pom.xml에 유효한 javax-servlet 버전과 servlet-api 버전을 추가해야 할 것 같습니다. 아래 예제를 통해 당신의 문제를 해결할 수 있을 것 같습니다.

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>3.0-alpha-1</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
       <version>1.2</version>
    </dependency>

spring boot project에서 netbean 오른쪽 클릭 run maven을 선택하고 set spring-boot:run in goals.
