尝试运行jar时出现NoClassDefFoundError
尝试运行jar时出现NoClassDefFoundError
提问于 2018-04-20 00:26:27
我的代码编译得很好，但是当我尝试运行Jar时，在堆栈跟踪中得到以下错误
java.lang.IllegalStateException: Error processing condition on org.springframework.cloud.stream.config.codec.kryo.KryoCodecAutoConfiguration
Caused by: java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.stream.config.ChannelBindingAutoConfiguration] from ClassLoader [org.springframework.boot.loader.LaunchedURLClassLoader@439f5b3d]
Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/actuate/endpoint/AbstractEndpoint
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.actuate.endpoint.AbstractEndpoint我也在我的pom.xml中添加了执行器作为依赖项。以下是所有依赖项：
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-streams</artifactId>
<version>1.0.1</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>我遗漏了什么？会不会是因为我使用的是spring boot版本？
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.1.RELEASE</version>
</parent>我还想知道这个执行器是从哪里来的，因为我在这个虚拟项目中只有两个类。
package demo.example.jobIDProcessor;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.integration.annotation.Transformer;
@EnableBinding(Processor.class)
@SpringBootApplication
public class JobIDProcessorApplication {
@Transformer(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
public String fetchJD(String jobID) {
return "ye raha JD of "+jobID;
}
public static void main(String[] args) {
SpringApplication.run(JobIDProcessorApplication.class, args);
}
}以及以下内容
package demo.example.jobIDProcessor;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.integration.annotation.Transformer;
@EnableBinding(Processor.class)
public class JobIDProcessorConfig {
@Transformer(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
public String fetchJD(String jobID) {
return "ye raha JD of "+jobID;
}
}这个"org/springframework/boot/actuate/endpoint/AbstractEndpoint“是从哪里被调用的？

这主要与您使用的云流依赖版本有关。请尝试在pom.xml中添加以下内容
<dependencyManagement>
<dependencies>
<dependency>
<!-- Import dependency management from Spring Boot -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-dependencies</artifactId>
<version>Fishtown.BUILD-SNAPSHOT</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<repositories>
<repository>
<id>spring-snapshots</id>
<name>Spring Snapshots</name>
<url>https://repo.spring.io/libs-snapshot</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>这将指向最新版本的cloud-stream-dependencies，该版本指的是执行程序的正确版本
