The operation summary of keytool, the things on the Internet are too pitiful, it is estimated that they are reproduced by others, and I have not experimented by myself. Now I will record my summary:
1. Generation of keystore
keytool -genkey -alias lean -keypass xfg456654 -keyalg RSA -keysize 1024 -validity 365 -keystore e:/lean.keystore -storepass xfg456654 -dname "CN=(first and last name), OU=(organizational unit name), O= (organization name), L=(city or region name), ST=(state or province name), C=(unit's two-letter country code)"
2. View keystore information
keytool -list -v -keystore e:/lean.keystore -storepass xfg456654
3. Certificate export
keytool -export -alias lean -keystore e:/lean.keystore -file e:/lean.crt -storepass xfg456654
4. View the exported certificate information
keytool -printcert -file e:/lean.crt
5. Import the certificate
keytool -import -keystore "%JAVA_HOME%/jre/lib/security/cacerts" -file e:/lean.crt -alias lean
输入密码：changeit
6. Delete the certificate
keytool -delete -alias lean -keystore "%JAVA_HOME%/jre/lib/security/cacerts" -storepass changeit
