Error:(35, 78) java: 不兼容的類型: java.util.Map<java.lang.String,java.lang.String[]>無法轉換爲java.util.Map<java.lang.String,java.lang.Object>

依賴裏面移除不兼容的servel-api版本即可，

 

 

Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

 

加上web的tomcat依賴

autoconfigure.session.SessionAutoConfiguration$ServletSessionConfiguration.cookieSerializer
