由于NoClassDefFoundError，无法启动embedded容器
我的SpringBoot应用程序与Eclipse IDE很好地工作，但是当我在Docker Container上运行我的应用程序时，它的图像生成良好，但是当我运行图像时，它将得到ClassDefnotfoundexception并且无法启动embedded容器。
How can I fix it?` In Dockerfile FROM java:8 EXPOSE 8080 ADD /target/docker.ras.jar docker.ras.jar RUN sh -c 'touch /docker.ras.jar ENTRYPOINT ["java","-jar","docker.ras.jar"] In pom.xml i also use maven plugin <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>example.docker.ras</groupId> <artifactId>docker.ras</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.3.RELEASE</version> </parent> <name>docker.ras</name> <url>http://maven.apache.org</url> <properties> <java.version>1.8</java.version> <start-class>docker.ras.App</start-class> <docker.image.prefix>springio</docker.image.prefix> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <version>1.3.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-core</artifactId> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>compile</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>0.4.11</version> <configuration> <imageName>${docker.image.prefix}/${project.artifactId}</imageName> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> <finalName>docker.ras</finalName> </build> </project>
我的错误堆栈跟踪
检查Docker容器中的Java版本。 希望你在神器之后运行应用程序。 如果是这样，确保它是添加所有的依赖关系。
这要么是您的部署中包含了服务器特定的API，要么是您的servlet API版本错误。 我怀疑前者。
如果你正在使用maven检查你的servlet api在pom中提供了一个范围。
