Could not open JDBC Connection for transaction

org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.)
Caused by:
org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure

在linux系统下部署项目,启动的时候就报这个错,在网上看了很多资料,有说hosts问题,有说配置文件问题,还有说连接池有问题,看了这么多也不知道改什么,希望大神能够指点指点。

检查连接字符串,你的数据库的配置,比如是否开启防火墙端口例外,用户账户和权限,网络是否连通等。

呐些過往 之前有一个项目已经部署了,用的oracle,现在部署的项目时mysql,然后这个新的项目就无法正常部署,不知道是否是连接的问题
接近 4 年之前 回复

你使用的jdbc还是jndi的方式,如果是jdbc的话,需要修改连接的url的

呐些過往 这个问题已经解决了,不知道是否有人改了什么连接或者用户信息,然后已经部署成功了,谢谢了

Springmvc在线程池中无法使用Service
问题:我在项目中使用线程池新建了线程列队,controller请求后把耗时任务交给列队处理, 列队中需要service注入,但是在Test中测,子线程无法使用service的方法,代码如下: TaskQueueHandler.java ``` public interface TaskQueueHandler { String getTaskName(); int doInvoke(); } ``` TaskSerialQueueService.java ... ``` @PostConstruct public void init(){ serviceThreadStatus=service.submit(new Thread(new Runnable() { @Override public void run() { while (running){ try{ TaskQueueHandler taskQueueHandler= tasks.take(); if(taskQueueHandler!=null){ try{ taskQueueHandler.doInvoke(); }catch (Exception e){ log.error(taskQueueHandler.getTaskName()+" doInvoke Error!",e.getCause()); } } }catch (InterruptedException e){ running=false; } } } })); } /** * 往列队中添加新任务 * @param taskQueueHandler * @return */ public synchronized boolean addTask(TaskQueueHandler taskQueueHandler){ if(!checkServiceIsActive()){ activeService(); } boolean success= tasks.offer(taskQueueHandler); if(!success){ log.warn(taskQueueHandler.getTaskName()+"任务列队添加失败!"); } return success; } ``` ... WxPayNotifyTask.java ``` public class WxPayNotifyTask implements TaskQueueHandler{ private String orderNo; public WxPayNotifyTask(String mOrderNo){ this.orderNo=mOrderNo; } @Override public String getTaskName() { return WxPayNotifyTask.class.getSimpleName(); } private OrderService orderService; @Override public int doInvoke() { System.out.println("orderNo="+orderNo); orderService= (OrderService)SpringUtils.getBean("orderService"); try{ OrderBean orderBean=orderService.queryByOrderNo(orderNo); System.out.println(orderBean.toString()); }catch (Exception e){ e.printStackTrace(); } return 0; } } ``` 测试代码中调用 ``` @Autowired private TaskSerialQueueService taskQueueService; taskQueueService.addTask(new WxPayNotifyTask("379991638464417792")); ``` 测试发现报错信息如下 ``` org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: interrupt at org.springframework.jdbc.datasource.DataSourceTransactionManager.doBegin(DataSourceTransactionManager.java:289) at org.springframework.transaction.support.AbstractPlatformTransactionManager.getTransaction(AbstractPlatformTransactionManager.java:377) at org.springframework.transaction.interceptor.TransactionAspectSupport.createTransactionIfNecessary(TransactionAspectSupport.java:461) at org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction(TransactionAspectSupport.java:277) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:96) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.interceptor.ExposeInvocationInterceptor.invoke(ExposeInvocationInterceptor.java:92) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.framework.CglibAopProxy$DynamicAdvisedInterceptor.intercept(CglibAopProxy.java:673) at com.superior.chalk.service.order.OrderServiceImpl$$EnhancerBySpringCGLIB$$d45a5b10.queryByOrderNo(<generated>) at com.superior.chalk.task.WxPayNotifyTask.doInvoke(WxPayNotifyTask.java:27) at com.superior.chalk.task.queue.TaskSerialQueueService$1.run(TaskSerialQueueService.java:35) at java.lang.Thread.run(Thread.java:745) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.sql.SQLException: interrupt ``` 最后发现如直接在test中使用 new WxPayNotifyTask("379991638464417792").invoke()是可以使用service的,但是在子线程中能获取到service但调用service的方法就报错。 先谢谢各位大佬帮忙分析分析!

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
