启动tomcat后，只要有数据操作mysql服务就自动关闭？

今天把项目部署到服务器上时，报了一个error。后来检查发现，mysql服务停止了，但是之前服务已经启动了。经过几次测试发现，没启动tomcat时，使用Navicat对数据库操作不会有问题，只要启动项目，一有数据操作就会自动停止mysql服务，这是什么情况？错误信息如下： 2017-11-01 08:49:35,007 ERROR [com.alibaba.druid.pool.DruidDataSource] - create connection error, url: jdbc:mysql://192.168.251.229:3306/creditteaching?useUnico de=true&characterEncoding=utf-8, errorCode 0, state 08S01 com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link fai lure The last packet sent successfully to the server was 0 milliseconds ago.

SSM框架下，数据库放置在docker下拒绝访问的问题

一个简单的评价系统，使用的SSM框架。最近将项目迁移到liunx系统上（deepin 15.4） IDE是idea 数据库是 mysql 因为想测试docker的功能，将数据库迁移到了docker镜像上， **使用jdbc驱动的方式访问docker的数据库，一切正常。** 使用mybatis的数据连接池，访问失败，提示拒绝访问。一直得不到Connection。非常疑惑 docker开放端口如下: ![docker开放端口](https://img-ask.csdn.net/upload/201706/15/1497497259_204023.png) jdbc.properties 文件内容如下： ``` jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3303/teachercommentdb?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC jdbc.username=root jdbc.password=794613 ``` spring-mybatis配置整合文件内容如下： ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">  <context:component-scan base-package="zyp"/>  <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties"/> </bean>   <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/>  <property name="initialSize" value="${initialSize}"/>  <property name="maxActive" value="${maxActive}"/>  <property name="maxIdle" value="${maxIdle}"/>  <property name="minIdle" value="${minIdle}"/>  <property name="maxWait" value="${maxWait}"/> </bean>  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/>  <property name="mapperLocations" value="classpath:zyp/mapping/*.xml"/> </bean>  <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="zyp.dao"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> </bean>  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean>  <tx:annotation-driven transaction-manager="transactionManager"/> </beans> ``` 提示如下错误，但跟网上说明的原因不太一样，不是超时连接，也不是用户名错误等。 ``` Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; 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.)] with root cause java.net.ConnectException: 拒绝连接 (Connection refused) ```

springboot+logback每日生成日志文件

用springboot+logback配置了每日生成日志文件，以前用log4j没有问题，现在用logback每日生成日志文件，刚启动应用服务器时可以生成，以后每天并没有生成新的文件，而是继续写入原来的文件，有哪位兄弟知道原因了。 logback配置如下 <?xml version="1.0" encoding="UTF-8"?>  <configuration debug="false">  <property name="LOG_HOME" value="@logback.log.file.path@"/>  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">  <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </encoder> </appender>  <appender name="WARN_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <FileNamePattern>${LOG_HOME}/platform_logger_warn_%d{yyyy-MM-dd}.log</FileNamePattern>  <MaxHistory>10</MaxHistory> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">  <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>DENY</onMatch> <onMismatch>ACCEPT</onMismatch> </filter>  <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>10MB</MaxFileSize> </triggeringPolicy> </appender>  <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <FileNamePattern>${LOG_HOME}/platform_logger_error_%d{yyyy-MM-dd}.log</FileNamePattern>  <MaxHistory>10</MaxHistory> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">  <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter>  <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>10MB</MaxFileSize> </triggeringPolicy> </appender>    <root level="@logback.log.root.level@"> <appender-ref ref="STDOUT"/> <appender-ref ref="WARN_FILE"/> <appender-ref ref="ERROR_FILE"/> </root>   </configuration>

javaweb项目部署到tomcat下，可以修改配置文件吗？

我创建了一个war包到tomcat的webapps下，自动解压后，我去修改项目的jdbc.properties文件，但是修改过后访问就会报错，（不能加载jdbc的驱动程序类${jdbc.driver}）,这是怎么回事？是打了war包就不能修改 ```  <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties" /> <property name="ignoreUnresolvablePlaceholders" value="true" /> </bean>  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" />  <property name="initialSize" value="${initialSize}"></property>  <property name="maxActive" value="${maxActive}"></property>  <property name="maxIdle" value="${maxIdle}"></property>  <property name="minIdle" value="${minIdle}"></property>  <property name="maxWait" value="${maxWait}"></property> </bean> ``` ``` jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/gykj_tksp?useUnicode=true&characterEncoding=UTF-8 jdbc.username=**** #password=**** jdbc.password=**** #定义初始连接数 initialSize=0 #定义最大连接数 maxActive=20 #定义最大连接空间 maxIdle=20 #定义最小连接空间 minIdle=1 #定义最长等待时间 maxWait=60000 idleConnectionTestPeriod=1800 maxIdleTime=14400 ``` 只要修改就报这个错 ``` nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class '${jdbc.driver}' ```

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...
