导入CA证书报错 keytool error: java.lang.Exception: Input not an X.509 certificate

导入CA证书报错：

keytool error: java.lang.Exception: Input not an X.509 certificate

如果你的CA证书是如下格式的：

-----BEGIN CERTIFICATE----- 
MIIFODCCBCCgAwIBAgIQU
yjELMAkGA1UEBhMCVVM
ExZWZXJpU2lnbiBUcnVz
U2lnbiwgSW5jLiAtIEZv
ZXJpU2lnbiBDbGFz
......
-----END CERTIFICATE-----

修改格式：保证除了begin、end，都在一行内

-----BEGIN CERTIFICATE----- 
MIIFODCCBCCgAwIBAgIQUyjELMAkGA1UEBhMCVVMExZWZXJpU2lnbiBUcnVzU2lnbiwgSW5jLiAtIEZvZXJpU2lnbiBDbGFz......
-----END CERTIFICATE-----

修改格式后导入成功：
