连接超时,先排除网络问题:
去线上机器ping 一下169.251.179.213,能ping通的话再检查一下telnet 169.251.179.213 3306,如果也没问题,那基本上就是代码的问题了。

b1198420279 回复qq_28104781: 嗯,根据你的描述,线下是没有问题的,线上又在报连接超时,所以怀疑是你线上的机器连不到数据库,在命令行执行以下命令,看看连接是不是好的

数据库链接的问题,生产上telnet 3306端口或用mysql客户端先试一下能不能连上

建议检查:生产环境的是否可以ping通数据库。
一般云服务商的虚机在互访问时屏蔽了外网ip,都是通过内网ip进行的。169.251.179.213这是一个公网ip。

你的数据库连接是是不是使用了useSSL = true了,而你的服务端没有开启这个,可以把useSSL =true 改为useSSL =false 试试吧

springboot2.2.1配置https的问题
## 环境 java:&emsp;&emsp;&emsp;&emsp;1.8.0\_231 springboot:&nbsp;&emsp; 2.2.1 内置tomcat:&emsp; 9.0.27 maven:&emsp;&emsp;&emsp;&emsp;3.6.2 idea:&emsp;&emsp;&emsp; 2019.2.4最新版 thymeleaf:&emsp;&emsp;3.0.11 ## 介绍 (两个项目) ### 第一个写了springSecurity和jwt,配置了druid(1.1.2) 按照正常方式配置了https,实现了http转https, ![配置文件](https://img-ask.csdn.net/upload/201911/20/1574250462_832231.png) ![http转https](https://img-ask.csdn.net/upload/201911/20/1574250506_961687.png) 项目启动正常,日志输出没有问题,访问页面,报错了 `ERROR logging.DirectJDKLog *log #175 -- Error running socket processor java.lang.UnsatisfiedLinkError: org.apache.tomcat.jni.SSL.renegotiatePending(J)I` ![图片说明](https://img-ask.csdn.net/upload/201911/20/1574249418_332121.png) ### 第二个项目 只写了一个简单的页面,没有其余的任何没用的东西,同样启动没有问题,访问页面报一样的错 ![图片说明](https://img-ask.csdn.net/upload/201911/20/1574249817_869827.png) 推测是tomcat版本问题,把springboot换成2.1.0,内置tomcat变成9.0.12,访问正常 又查到相关的话题是tomcat的tomcat-native版本问题,但是得不到更多的有用信息,也不知道怎么换版本。 对了,期间使用了外置的tomcat9.0.12,启动访问都没有问题,之前修改了tomcat的server.xml,配置成http转https,修改了web.xml,加了一些标签,如图。 ![图片说明](https://img-ask.csdn.net/upload/201911/20/1574251125_261342.png) 之后又使用了外置的tomcat9.0.27部署,访问正常。 ## 总结 springboot2.2.1,内置tomcat9.0.27,访问失败 springboot2.1.0,内置tomcat9.0.12,访问成功 springboot2.2.1和springboot2.1.0,外置tomcat,访问成功 推测是tomcat的web.xml配置的那几行标签起了作用,但是不敢妄断。 (空一行,以示敬重) 前辈们,咋办呢?? <br/><br/><br/>又试了一下,去掉外部tomcat9.0.27的web.xml的配置也可以正常运行,内置的相同版本不行,是不是找问题的方向错了,其他东西都没有配置,不一样的就是内部web.xml是通过ServletWebServerFactory设置的,但是设置成功了啊,http可以跳转到https。。。。。。。。。 <br/> 望大佬指点????

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;

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 ```

Druid连接SqlServer报错,为啥都连接了sqlserver还执行SHOW TABLES?
SpringBoot + Guns脚手架改成使用sqlserver,在最后时刻报错了,原因是sqlserver执行了mysql的语句SHOW TABLES,druid内部会执行这一句吗?mysql转sqlserver该如何实现? ``` 2019-12-09 15:04:10.196 INFO 3788 --- [ restartedMain]

关于切换了网络springboot就无法管理MongoDB的问题,请大神帮忙看下啥问题
我通过idea MongoDB,MongoDB是安装在阿里云上的, ![图片说明](https://img-ask.csdn.net/upload/201910/17/1571294846_570092.png) 可以管理MongoDB,并可以做到新增修改查询数据 然后通过springboot代码管理,在家里或者通过手机热点可以管理MongoDB,但是到了公司,连接公司的网络却没法管理。 但是,我通过spring+MongoDB连接却可以在公司网络管理MongoDB,我的springboot管理MongoDB代码上传到GitHub上的,地址: https://github.com/jxhun/mongo.git 然后报错是: ``` 2019-10-17 14:55:17.331 ERROR 10884 --- [nio-8082-exec-7]

java内存溢出问题,不确定哪里出的问题
项目运行的时候出现了内存溢出情况,复现方式无法确定,大概出现了五六次,每次复现的方式都不一样,下面是我用MAT工具分析的dump文件 ![图片说明](https://img-ask.csdn.net/upload/202001/20/1579508231_612899.png) ![图片说明](https://img-ask.csdn.net/upload/202001/20/1579508244_502327.png) 除了hibernate里的那两个对象,其他的1000多万个对象里全是integer类型的对象 这是当时出现的时候产生的异常 ``` 2020-01-17 13:32:55 ERROR [DruidDataSource.java:2469] - create connection SQLException, url: jdbc:mysql://localhost:55060/mcs?useUnicode=true&characterEncoding=utf-8, errorCode 0, state 08S01 com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 1 milliseconds ago.

Apache Kafka是消息引擎系统,也是一个分布式流处理平台(Distributed Streaming Platform) Kafka是LinkedIn公司内部孵化的项目。LinkedIn最开始有强烈的数据强实时处理方面的需求,其内部的诸多子系统要执行多种类型的数据处理与分析,主要包括业务系统和应用程序性能监控,以及用户行为数据处理等。 遇到的主要问题: 数据正确性不足 数据的收集主要...
volatile 与 synchronize 详解
Java支持多个线程同时访问一个对象或者对象的成员变量,由于每个线程可以拥有这个变量的拷贝(虽然对象以及成员变量分配的内存是在共享内存中的,但是每个执行的线程还是可以拥有一份拷贝,这样做的目的是加速程序的执行,这是现代多核处理器的一个显著特性),所以程序在执行过程中,一个线程看到的变量并不一定是最新的。 volatile 关键字volatile可以用来修饰字段(成员变量),就是告知程序任何对该变量...
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...

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
