Springboot2.2.2不能连接数据库

1.写一个体验redis缓存的demo,不能连接数据库。
导入其他人的项目可以,连接自己的数据库,可以连接成功。确定数据库连接信息没有写错。参考网上,修改mysql-connector-java的版本也没有用。

mysql-5.1.62 版本太低了;
两种解决方案,(1)升级MySQL(2)降低mysql-conn.jar版本,你看日志项目默认用的MySQL Connector / J 8.0.18
https://img-ask.csdn.net/upload/202001/06/1578275918_258494.png

参考文档:https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-versions.html

niaonao 回复weixin_39825906: 你先把本地maven仓库的mysql-conn jar包备份后删除,重新使用Maven 拉去依赖,应该就是5 版本的了

niaonao 回复weixin_39825906: 不是,我看到你maven配置了,但是你的项目默认使用了8.018版本jar,你看控制台日志;升级MySQL太麻烦,建议还是用低版本conn.jar包

Taltoo 我将mysql-connector-java版本降到5.1.62甚至更低也没有用,只能升级Mysql了吗 <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.62</version> <scope>runtime</scope> </dependency>

建议换回5的版本,8有很多兼容问题,头硬的话百度错误关机键

springboot2.1.4 + jpa + hibernate 使用aop注解形式实现多数据源管理 可能懒加载出现问题求大神解答
最近项目中使用springboot2.1.4 + jpa + hibernate 使用aop注解形式实现多数据源管理,用的就是网上大多数人使用的一套代码,但是我在项目中使用后发现如果配置 spring配置文件 application.yml 中open-in-view: false 跨数据源查询正常,但是保存或者修改失败原因是事务没有提交,一旦把open-in-view改成true则不能跨数据源查询,修改保存正常事务正常提交求解,具体代码如下实现 1. application.yml ``` spring: ## 数据库配置 #datasource: #driver-class-name: com.mysql.jdbc.Driver #url: jdbc:mysql://192.168.101.125:3306/cdv?useSSL=false&characterEncoding=utf-8 #username: root #password: 123456 #url: jdbc:mysql://127.0.0.1:3306/boot-jpa-back-sys2?useSSL=false&characterEncoding=utf-8 #username: root #password: datasource: test1: driver-class-name: com.mysql.jdbc.Driver jdbc-url: jdbc:mysql://192.168.101.125:3306/cdv?useSSL=false&characterEncoding=utf-8 username: root password: 123456 type: com.alibaba.druid.pool.DruidDataSource test2: driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver jdbc-url: jdbc:sqlserver://192.168.101.125:1433;database=Test;

sqlite 如何共享访问,文件夹共享就不必说了
项目上用springboot开发了个小项目,初选的sqlite数据库,后来部署时发现,tomcat服务器是用nginx做了个负载, 两台机器但是发现sqlite没法用ip访问,只能用地址连接,网上说可以把文件夹共享一下,服务器不允许共享文件夹, 这可咋整。。。。求大神指教!!!!! 1.sqlite如何共享访问 2.或者哪些小型数据库支持共享访问 3.其他办法
springboot 配置hibernate 开始使用的是mysql,都正常,但是换成Oracle后总是创建表。
springboot 配置hibernate 开始使用的是mysql,都正常,但是换成Oracle后总是创建表。所以后台报如下表重复错误。这是为什么呀?应该是如果发现表已经有的话不应该再创建才对,请帮我看下哪里配置错了。 再详细说明下我的场景: 数据库映射的对象Product。 第一次系统启动肯定会创建一个,因为数据库中是没有这个表,然后系统重启或者再次启动,正常来讲,Product对象没有改过,数据库表也存在,hibernate不应该再创建,但是目前就是再创建,所以报表名已经有的错误。 ``` Caused by: java.sql.SQLSyntaxErrorException: ORA-00955: 名称已由现有对象使用 at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:447) ~[ojdbc-6.6.0.jar:11.2.0.4.0] at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:396) ~[ojdbc-6.6.0.jar:11.2.0.4.0] at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:951) ~[ojdbc-6.6.0.jar:11.2.0.4.0] ``` ``` server: port: 8001 spring: application: name: DEMO_TEST #f服务名称定义 datasource: type: com.alibaba.druid.pool.DruidDataSource # 当前数据源操作类型 #driver-class-name: com.mysql.cj.jdbc.Driver # mysql驱动包 driver-class-name: oracle.jdbc.driver.OracleDriver #url: jdbc:mysql://127.0.0.1:3306/rd_plm?serverTimezone=GMT%2B8 # 数据库名称 url: jdbc:oracle:thin:@127.0.0.1:1521/DD username: root password: root dbcp2: min-idle: 5 # 数据库连接池的最小维持连接数 initial-size: 5 # 初始化连接数 max-total: 5 # 最大连接数 max-wait-millis: 150 # 等待连接获取的最大超时时间 jpa: hibernate: naming: physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl ddl-auto: update show-sql: true properties: hibernate: #dialect: org.hibernate.dialect.MariaDBDialect dialect: org.hibernate.dialect.OracleDialect current_session_context_class: org.springframework.orm.hibernate5.SpringSessionContext #database: MYSQL database: oracle open-in-view: true ```

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

20行Python代码爬取王者荣耀全英雄皮肤

网络(8)-HTTP、Socket、TCP、UDP的区别和联系
TCP/IP协议是传输层协议,主要解决数据如何在网络中传输,而HTTP是应用层协议,主要解决如何包装数据。 一、TCP与UDP的不同 1. 是否需要建立连接。 UDP在传送数据之前不需要先建立连接;TCP则提供面向连接的服务; 2. 是否需要给出确认 对方的传输层在收到UDP报文后,不需要给出任何确认,而 TCP需要给出确认报文,要提供可靠的、面向连接的传输服务。 3.虽然UDP不提供可靠交...

聊聊C语言和指针的本质
坐着绿皮车上海到杭州,24块钱,很宽敞,在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传,然而,对于C语言,指针却是与生俱来的。 那么,什么是指针,为什么大家都想避开指针。 很简单, 指针就是地址,当一个地址作为一个变量存在时,它就被叫做指针,该变量的类型,自然就是指针类型。 指针的作用就是,给出一个指针,取出该指针指向地址处的值。为了理解本质,我们从计算机模型说起...
