问题描述

我使用 Spring Boot 1.2.3 启动了一个新项目.我收到错误

I Started a new project with Spring Boot 1.2.3. I'm getting error

java.lang.NoClassDefFoundError: javax/servlet/Filter

Gradle 依赖:

dependencies {
    compile("org.springframework.boot:spring-boot-starter-actuator")
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("org.springframework.boot:spring-boot-starter-security")
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.codehaus.groovy:groovy")
    compile("com.h2database:h2")
    compile("org.thymeleaf.extras:thymeleaf-extras-springsecurity3")

    providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
    testCompile("org.springframework.boot:spring-boot-starter-test")

    compile 'org.webjars:jquery:2.1.4'
    compile 'org.webjars:bootstrap:3.3.4'
}

这是完整的堆栈跟踪

推荐答案

对于 maven 用户，注释以下依赖项中提供的范围:

for the maven users, comment the scope provided in the following dependency:

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

更新

正如 feed.me 提到的，您必须根据您部署的应用程序类型取消注释所提供的部分.

As feed.me mentioned you have to uncomment the provided part depending on what kind of app you are deploying.
