1.问题描述:
对于创建的springboot项目,通过启动类启动,访问没问题,但打成war部署到tomcat上启动报错,如下:
严重: ContainerBase.addChild: start:

2.问题分析:
该错是由于application启动类中嵌入的tomcat与部署war的tomcat冲突引起的,需要在pom.xml添加配置,来避免冲突!
3.问题解决:
修改pom.xml文件,添加依赖如下:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
