Question

我正在尝试使用Kafka作为经纪人来锻炼Spring Cloud Stream应用程序。 pom文件看起来像： -

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring.boot.version>1.4.2.RELEASE</spring.boot.version>
        <spring.cloud.version>Camden.SR3</spring.cloud.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <!-- Import dependency management from Spring Boot -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring.boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring.cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>



    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-integration</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-core</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-stream-kafka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.5.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

主要课程： -

@SpringBootApplication
public class BootWebappApplication {

    public static void main(String[] args) {
        SpringApplication.run(BootWebappApplication.class, args);
    }
}

试图运行这个回复： -

Caused by: java.lang.ClassNotFoundException: org.springframework.integration.codec.kryo.KryoRegistrar
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

我认为依赖版本在某处搞砸了 - 我在这个日期使用的是最新版本。

用于＆＃39; spring.boot.version＆＃39;的正确版本是什么？＆安培; ＆＃39; spring.cloud.version＆＃39;如果那确实是问题

Answer 1

尝试使用此

 <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Brixton.SR5</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>

Spring Cloud Stream：ClassNotFoundException：org.springframework.integration.codec.kryo.KryoRegistrar
