eureka配置启动

**报错1：** java.lang.classnotfoundexception: org.springframework.boot.bind.relaxeddatabinder

首先检查包文件是否引用正确

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <version></version>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter</artifactId>
                <version></version>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-eureka-server</artifactId>
                <version></version>
            </dependency>

**报错2：**Failed to process import candidates for configuration class \[com.itmayedu.app.EurekaServer\]; nested exception is java.io.FileNotFoundException: class path resource \[org/springframework/boot/autoconfigure/web/ServerPropertiesAutoConfiguration.class\] cannot be opened because it does not exist

遇见这个问题，额你最好从头检查一下你的包的各种version，因为是包版本不兼容导致的

比如是不是有使用已经被被废弃的包文件

Spring Cloud Starter Netflix Eureka Server和Spring Cloud Starter你会发现版本基本都是匹配的不会出现所谓的包版本不匹配问题。

很多老一点的教学视频会出现Spring Cloud Starter Eureka Server 建议使用该版本的最好修改或更新至Netflix Eureka版本。

**报错3： compatible version of com.google.gson.GsonBuilder**
