最近搭建springboot启动报错:
org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat

报错信息如下:

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat

尝试了各种方式都无法解决,但是如果把@EnableEurekaServer和关于eureka的配置都去掉,SpringBoot则可以正常启动。

搞了半天,网上查了下,原来是JDK版本问题。

从java9开始,模块化的概念使得JAXB默认没有加载;jaxb-api是存在jdk中的,只是默认没有加载而已,我们需要手动引入。

接下来引入如下jaxb依赖:

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.2.11</version>
</dependency>
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.11</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.2.10-b140310.1920</version>
</dependency>
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>

再次启动SpringBoot,项目启动成功!
