Spring Boot和Spring云配置客户端错误

Question

我正在尝试使用spring cloud配置客户端配置并运行spring Boot应用程序。我已经成功运行了配置服务器，但客户端在加载应用程序上下文时出现错误。

在搜索时，我得到了指向版本/依赖冲突等的指针，并尝试使用不同的版本。任何帮助都将不胜感激。

错误代码段：

Caused by: java.lang.ClassNotFoundException: org.springframework.context.event.GenericApplicationListener
    at java.net.URLClassLoader$1.run(URLClassLoader.java:372)

Answer 1

尝试将以下内容添加到＜code＞中：

    <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-parent</artifactId>
            <version>Angel.SR4</version>
            <type>pom</type>
            <scope>import</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>1.3.1.RELEASE</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency> 

Answer 2

天使发布系列构建于Spring Boot 1.2.x之上，在某些方面与Spring Boot 1.3.x不兼容。因此，我将Spring Boot的版本更改为< code>1.2.7.RELEASE:

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.2.7.RELEASE</version>
</parent>
