解决办法
打开application.properties文件中的数据库配置
spring.datasource.url=jdbc:postgresql://localhost:5432/tpt?characterEncoding=utf8&useSSL=true&autoReconnect=false&rewriteBatchedStatements=true
把userSSl改为false即可
spring.datasource.url=jdbc:postgresql://localhost:5432/tpt?characterEncoding=utf8&useSSL=false&autoReconnect=&rewriteBatchedStatements=true
