错误日志

查看 logs/start.out，可以看到报错信息

2023-04-09 19:36:23,081 ERROR Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException.

解决方案

Failed to instantiate (con. alibaba, nacos, olugin, auth. imol, token. imol. JitTokenManager]: Constructor threw exception;

可以看到提示我们一个秘钥是必须配置的，我们打开这个网址

参数	默认值	启止版本	说明
nacos.core.auth.plugin. nacos.token.secret.key	SecretKey01234567 89012345678901234567 89012345678901234567 890123456789(2.2.0.1后无默认值)	2.1.0 ~ latest	默认鉴权插件用于生成用户登陆临时accessToken所使用的密钥，使用默认值有安全风险

然后我们修改 conf/application.properties 文件

找到nacos.core.auth.plugin.nacos.token.secret.key这个字段给他赋值临时值：SecretKey01234567
8901234567890123456789012345678901234567890123456789
