idea中pom.xml无法导入jdbc的jar包

----_这问题勉强已解决,我直接结贴吧_ ------


<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.38</version>
</dependency>

查看本地仓库,发现只有下面这个文件:

lastupdate内容如下:

还有其他几个版本我都无法导入,

已尝试:重新复制粘贴;关闭代理;重启idea;mvn clean/compile;


---在这记一下解决经过以后留个印象---

尝试重装了该版本的maven,又下了一个idea2020,仓库备份后清空,settings.xml去掉镜像。
一开始去掉阿里镜像,结果也不行,右侧包括pulgin在内全部飘红,mvn命令除了-v全部error,删掉本地项目后reimport又再次生成的也只有一个lastUpdated文件,报错信息看起来就像是说我少了证书,网上一查让加参数试了也不行,和证书好像没啥关系。
后来新建了一个新maven项目,reimport终于有反应了,然后回到老项目里重新剪切粘贴reimport,这次终于可以从中央仓库下载依赖了,虽然速度慢,但加上阿里镜像就不行了,应该是镜像问题,也不知道今天怎么突然就这样了。我意识到两点:

  • 网速不行确实会造成mvn命令执行失败,但不会像这样一直失败,重新执行一次即可;
  • 如果中途加了settings.xml文件的mirror,再次reimport,结果失败pom文件飘红,造成即使立刻注释掉mirror点刷新也没有反应,重启一下idea。

可能是网络不好下不下来。把 jdbc 放到 web-inf/lib 目录下,可以走本地导入方式:

<dependency>
            <groupId>xx</groupId>
            <artifactId>xx</artifactId>
            <version>1.0.0</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/xxx.jar</systemPath>
        </dependency>

3162105 本地的确实可用,但我现在也没有解决:(,我的网络没问题,我尝试修改了下镜像,现在log4j等等好像全都无法下载了,reimport时Build报错:Could not transfer artifact log4j:log4j:pom:1.2.17 from/to nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public) sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

关于maven项目导入jdbc驱动的问题

这是我在maven项目下创建的一个工具类,想要在某些操作后向mysql数据库导入信息 ![图片说明](https://img-ask.csdn.net/upload/201806/28/1530166852_26878.png) 运行之前我导入过mysql的包 ![图片说明](https://img-ask.csdn.net/upload/201806/28/1530166919_122838.png) 但是运行时,jdbc的驱动一直无法加载成功,代码没有被运行 后来我在网上查了查,当修改pom.xml时又会报错 ![图片说明](https://img-ask.csdn.net/upload/201806/28/1530167308_912958.png) 想问问还有没有什么办法能加载起jdbc的驱动?

springboot测试动态加载mysql不同版本驱动jar,总调用的是pom中的驱动jar版本

最近在测试用springboot的web项目,做个各个数据库(mysql、oracle,sqlserver,postgresql)的数据源管理,用URLClassLoader动态加载不同版本的驱动jar包,就mysql来说 每次conn.getMetaData().getDriverVersion()发现连接使用的驱动版本是pom中项目的版本,并没有使用我在URL中给的本地驱动,苦恼 ``` package com.legends.ori.service.type; import com.legends.ori.service.tool.JarLoader; import java.io.File; import java.net.URL; import java.net.URLClassLoader; import java.sql.Connection; import java.sql.Driver; import java.sql.DriverManager; import java.sql.DriverPropertyInfo; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.SQLFeatureNotSupportedException; import java.sql.Statement; import java.util.HashMap; import java.util.Map; import java.util.Properties; import java.util.logging.Logger; public class MycatMulitJdbcVersionTest { private static final String JDBC_URL = "jdbc:mysql://localhost:3306/test?serverTimezone=Asia/Shanghai"; private static final String USER = "root"; private static final String PASSWORD = "root"; private static final Map<String, String> jdbcVersionMap = new HashMap<String, String>(); private static final Map<String, Driver> tmpDriverMap = new HashMap<String, Driver>(); // 动态加载jdbc驱动 private static void dynamicLoadJdbc(String mysqlJdbcFile) throws Exception { File jarPath = new File("D:\\Idea-Projects\\raytracing\\driver\\mysql\\" + mysqlJdbcFile); URL u = jarPath.toURI().toURL(); String classname = jdbcVersionMap.get(mysqlJdbcFile); URLClassLoader ucl = new URLClassLoader(new URL[]{u},Thread.currentThread().getContextClassLoader()); //ucl.loadClass(classname).newInstance(); Driver d = (Driver) ucl.loadClass(classname).newInstance(); DriverShim driver = new DriverShim(d); DriverManager.registerDriver(driver); tmpDriverMap.put(mysqlJdbcFile, driver); } // 每一次测试完卸载对应版本的jdbc驱动 private static void dynamicUnLoadJdbc(String mysqlJdbcFile) throws SQLException { DriverManager.deregisterDriver(tmpDriverMap.get(mysqlJdbcFile)); } // 进行一次测试 private static void testOneVersion(String mysqlJdbcFile) { System.out.println("start test mysql jdbc version : " + mysqlJdbcFile); try { dynamicLoadJdbc(mysqlJdbcFile); } catch (Exception e1) { e1.printStackTrace(); } Connection conn = null; try { conn = DriverManager.getConnection(JDBC_URL, USER, PASSWORD); System.out.println(conn.getMetaData().getDriverVersion()); } catch (SQLException e) { e.printStackTrace(); } finally { if (conn != null) { try { conn.close(); } catch (SQLException e) { e.printStackTrace(); } } } try { dynamicUnLoadJdbc(mysqlJdbcFile); } catch (SQLException e) { e.printStackTrace(); } System.out.println("end !!!"); System.out.println(); } public static void main(String[] args) { jdbcVersionMap.put("mysql-connector-java-5.1.48.jar", "com.mysql.jdbc.Driver"); jdbcVersionMap.put("mysql-connector-java-8.0.17.jar", "com.mysql.cj.jdbc.Driver"); for (String mysqlJdbcFile : jdbcVersionMap.keySet()) { testOneVersion(mysqlJdbcFile); } } } class DriverShim implements Driver { private Driver driver; DriverShim(Driver d) { this.driver = d; } public boolean acceptsURL(String u) throws SQLException { return this.driver.acceptsURL(u); } public Connection connect(String u, Properties p) throws SQLException { return this.driver.connect(u, p); } @Override public DriverPropertyInfo[] getPropertyInfo(String url, Properties info) throws SQLException { return this.driver.getPropertyInfo(url, info); } @Override public int getMajorVersion() { return this.driver.getMajorVersion(); } @Override public int getMinorVersion() { return this.driver.getMinorVersion(); } @Override public boolean jdbcCompliant() { return this.driver.jdbcCompliant(); } @Override public Logger getParentLogger() throws SQLFeatureNotSupportedException { return this.driver.getParentLogger(); } } ``` 测试结果: 1.pom中不添加mysql-connector-java8.0.16的版本,测试OK ![图片说明](https://img-ask.csdn.net/upload/202004/15/1586942491_75054.png) 2.pom中添加mysql-connector-java8.0.16的版本,测试使用的驱动版本就变成了8.0.16,我在URLClassLoader添加驱动的无效 ![图片说明](https://img-ask.csdn.net/upload/202004/15/1586942638_686759.png) 求求大神解救

依赖包都是下载好教材里的,何来Failed to read artifact descriptor for xxx:jar:1.0-SNAPSHOT.

上午还好好的,下午增加了一个module,配置了些东西。这时候另外的module倒报上错了,具体就是pom.xml开头的project下红波浪,Failed to read artifact descriptor for com.tensquare:tensquare_common:jar:1.0-SNAPSHOT. 删了新增模块,红线还在,再新增,又不见了,接着轮到新增模块报同样的错。无法读取common?那么多其他模块都依赖common,都没问题,偏偏它出问题。

maven,自己的 程序包不存在?

IDEA配置druid监控spring jdbc报错“Cannot resolve Spring Pointcut 'druid-stat-pointcut'”

使用IDEA开发一个SSM项目,在spring-mybatis.xml整合文件内配置druid监控spring jdbc,但总是报错“Cannot resolve Spring Pointcut 'druid-stat-pointcut'”,而同样的配置在eclipse(我用的是STS)下完全可以运行。 我的配置代码如下: ``` <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"> </bean> <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype"> <property name="patterns"> <list> <value>jtl.service.*</value> </list> </property> </bean> <aop:config proxy-target-class="true"> <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /> </aop:config> ``` pom.xml中已经添加了AOP jar包: ``` <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.1</version> </dependency> ``` 各位帮忙看一下,问题出在哪里,同样的代码,在eclipse下完全可以运行。

急!在线等。使用maven把项目打成war包,java文件没有被包含进去!!!!

希望大牛能帮我解答一下疑惑,小弟感激不尽。 项目介绍:自己搭的Spring Spring MVC MyBatis JavaWeb项目,JDK:1.8. 今天用maven打包项目,莫名其妙的java文件就打包不进去了, 没有修改过pom.xml文件,执行mvn clean install / mvn package / mvn compile 都打包成功,不报错,但是就是没有包含进java文件

使用IDEA开发一个SSM项目,在spring-mybatis.xml整合文件内配置druid监控spring jdbc,但总是报错“Cannot resolve Spring Pointcut 'druid-stat-pointcut'”,而同样的配置在eclipse(我用的是STS)下完全可以运行。 我的配置代码如下: ``` <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"> </bean> <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype"> <property name="patterns"> <list> <value>jtl.service.*</value> </list> </property> </bean> <aop:config proxy-target-class="true"> <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /> </aop:config> ``` pom.xml中已经添加了AOP jar包: ``` <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.1</version> </dependency> ``` 各位帮忙看一下,问题出在哪里,同样的代码,在eclipse下完全可以运行。

JAVA初级工程师面试36问(完结)

第三十一问: 说一下线程中sleep()和wait()区别? 1 . sleep()是让正在执行的线程主动让出CPU,当时间到了,在回到自己的线程让程序运行。但是它并没有释放同步资源锁只是让出。 2.wait()是让当前线程暂时退让出同步资源锁,让其他线程来获取到这个同步资源在调用notify()方法,才会让其解除wait状态,再次参与抢资源。 3. sleep()方法可以在任何地方使用,而wait()只能在同步方法或同步块使用。 ...
