idea springboot helloworld出错

idea springboot helloworld出错

eclipse实在太卡了太难用了，装了intellj idea，配置环境，出了两个错误：

1、

java.lang.NoClassDefFoundError: org/springframework/expression/ParserContext

对应jar包下载失败，重新下载。若存在该jar包，一般里面是没有内容的，删除它，重新下载；

2、报错信息如下：

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

版本写错了，将

org.springframework.boot

spring-boot-starter-parent

2.0.0.RELEASE

改成

org.springframework.boot

spring-boot-starter-parent

1.5.10.RELEASE
