Question

我有一个Spring Boot应用程序，我正在更新到1.5.1。它很棒，直到我将Sleuth和Zipkin添加到classpath

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
    </dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-sleuth-zipkin</artifactId>
</dependency>

当这些行存在时，我得到

2017-02-22 22:33:05.331 ERROR [chathub-api,,,] 7581 --- [           main] o.s.boot.SpringApplication               : Application startup failed

java.lang.NoClassDefFoundError: org/springframework/boot/context/embedded/FilterRegistrationBean

这是我的部门。管理

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Camden.SR4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

我尝试过改为Dalston

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Dalston.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>

但错误甚至更奇怪

***************************

我错过了一些我还没注意到的东西吗？

Answer 1

我无法解释你用Dalston.BUILD-SNAPSHOT得到的错误，但是Camden.SR4的错误是因为它与Spring Boot 1.5不兼容。我建议升级到Camden.SR5 which is compatible with Spring Boot 1.5。

Answer 2

即使我在设置项目时遇到此错误。我使用Spring引导1.5.8和Brixton.SR6版本。但是，当我咨询网站http://projects.spring.io/spring-cloud/时，我知道了这个问题，并将我的依赖关系更新为Dalston.SR4，然后应用程序开始工作。
