1.Error:java: 错误: 不支持发行版本 5 此处改成自己电脑上的java的版本即可
2.Error:(3, 32) java: 程序包org.springframework.boot不存在 解决方案:
3.运行后,加载依赖包; 比较缓慢 采用阿里云的镜像来完成: 步骤一:overide打勾 步骤二:在上图的这个路径下的settings.xml文件中加入一下内容(这个文件可能不存在,则新建):
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd"> <mirrors> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> </settings>步骤三:重新打开idea,再次运行即可; 但是我在这种情况下仍然不行,报类似如下错误 Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.2.4.RELEASE from/to alimaven (https://maven.aliyun.com/repository/central): PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 解决方案: 1.在画圈处加入如下代码:应用并保存
-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true2.打开右侧的maven,点击clean,然后再次尝试运行程序即可; (原博客的方式是:clean, complier, install) 原博客:https://blog.csdn.net/xxaann/article/details/104794669

如果自己的数据库是mysql8.0,则错误原因是时区问题: 将java中的url,将时区修改为UTC
