eclipse中启动SSM项目，报这个错是啥原因？用的Tomcat8.0和jdk8.0。

Posted 2023-04-04

java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1333)
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1167)
java.lang.ClassNotFoundException: org.springframework.web.util.IntrospectorCleanupListener

参考技术A 检查一下有没有这个com.xhcms.regis.service.DivisionService。环境对不对。
你没有在WebContent文件夹下面新建一个.jsp文件，没有jsp文件就无法显示网页，因为没有网页可以显示，所以报错了，你能访问tomcat主页是因为用eclipse启动tomcat了（和直接手动启动一样的效果）所以能访问主页。

python Django启动报错是啥原因

Type 'manage.py help <subcommand>' for help on a specific subcommand.

Available subcommands:

[django]
check
compilemessages
createcachetable
dbshell
diffsettings
dumpdata
flush
inspectdb
loaddata
makemessages
makemigrations
migrate
runserver
sendtestemail
shell
showmigrations
sqlflush
sqlmigrate
sqlsequencereset
squashmigrations
startapp
startproject
test
testserver
Note that only Django core commands are listed as settings are not properly configured (error: The TEMPLATE_DIRS setting must be a list or a tuple. Please fix your settings.).

参考技术A 启动要带参数的，
python manage.py runserver
