idea创建maven项目提示添加依赖

pom.xml中添加了运行servlet所需的依赖 ``` <dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> </dependencies> ``` 但是具体的servlet无法自动导包，仍然提示添加依赖  ``` package cn.itheima.setvlet; import java.io.IOException; public class MyServlet extends HttpServlet { protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } } ``` 找不到解决方法，搞得我怀疑人生，跪求大哥指点

Maven中的test测试类ClassNotFoundException

在IDEA上使用quickstart新建一个maven工程，在test中的AppTest中写测试代码执行正常，但是自己新建的test测试类提示”找不到或无法加载主类“。 在不使用quickstart新建一个空白maven工程的时候，出现如上同样的报错。搜索了很久，没找到解决办法， 求指点  执行main方法报错如下  感谢@毕小宝 提供的解决思路 另外附上解决方案：[https://blog.csdn.net/Dawn510/article/details/103598714](https://blog.csdn.net/Dawn510/article/details/103598714 "")

请问idea如何方便的进行多分支开发

请不要答非所问! 请不要答非所问! 请不要答非所问! 我知道如何拉出新分支,我也知道如何合并分支到主线。 我的问题是:《出于工作需要,分别对主线和分支进行开发的时候,如何快速的从主线工作中切换到分支工作中》 你问我为什么会有这么个问题? 好的,以下就是我的困境: 项目是maven管理的web项目,需要使用maven命令进行compile、package等工作。(什么?右方侧边栏就有?抱歉,那玩意用不了,因为没法配置参数)所以我们必须定义一套Debug Configurations。当然,定义好了之后,用起来是很方便的。 然而痛苦的事情发生了,使用idea检出项目到文件夹下之后,它是一个全新的工作空间,所有配置都是空的!也就是说,当从主线切换到分支进行工作的时候,必须首先down下分支,然后把那一大套Debug Configurations重新设置一遍,然后再进行开发。(什么?直接把主线切过去不就行了?开什么玩笑,只有我和鬼才知道主线上有什么未提交的魔法代码,现在只有鬼知道) 诚然我看到了太多idea比Eclipse优越的原因,但我不想听那些,我只想得到该有的解决方案。不得不说,Eclipse成熟的应用环境,使得对Eclipse的任何操作问题都可以很方便的得到答案,而idea么……现在的网上,大量的复制粘贴,大量的枪手宣传文,却没有找到有价值的指南…… =_=就好像我迄今都没能完美解决skip test的问题。我们都知道,在eclipse下,应用maven跳过test的情况下,完全不必在乎它。但在idea下,如果test包中有error,我们就不能编译它。(你问我为什么不把error干掉?因为那里有魔法) 我当然知道右面的侧边栏中有一个小按钮,按一下就可以跳过test了,我当然也知道maven命令Dmaven.test.skip=true。但那些都没有用,maven管理的多项目依赖,test包下的文件是要依赖于其它项目下的test包的。如果被依赖的项目,其test包被skip掉而不再编译的话,那么当前项目下对应的test包下文件就会因为无法导入正确的包从而出现error。有error,那么编译就无法正常执行。这就是为什么即使跳过了test包也无法正常编译的原因! 你知道我现在是怎么解决问题的吗? 没错,我把test包下的一切都删掉了=_= 除非真的有办法解决我的问题,否则我不打算把悬赏丢给任何一个草率的回应者。

IntelliJ IDEA中 子项目文件路径问题，求解决

先看图，然后我仔细解释 最近发现找不到文件，同样的代码在eclipse中可以正常找到，对于idea不熟悉，所以来此请教，我是把一些文件拷resources目录下，发现找不到了，使用相对路径，我看到target/classes中是编译过去了的啊，这个路径该怎么写？ 在eclipse中 （1） 主项目包含的两个模块 topsoft-test(web项目) topsoft-utils(java maven项目) （2）（3）（4） 根据new File("log4j.xml);以及创建文件可以发现路径是相对于子项目topsoft-utils 的跟路径，(4)标注了这个测试类是在topsoft-utils中运行的 （5） 假如说我想访问（5）标注处的这个文件，相对路径该怎么写？ 转到IntelliJ IDEA中，目录结构一样，运行的测试也是一样，打印出来的目录不同，我想这是IDE的区别，或者说是在IDEA的配置当中哪里出了问题，导入maven项目我就默认的 Project Structure 我看到里面有三个模块。 路径中只写文件名不是相对于classpath路径么，为什么相对于项目的跟路径了，eclipse中这样可以接受，至少还能加上src/main/....访问到，而在IntelliJ中就完全不对了，主项目打包会产生子项目的jar包，而我访问的文件应该是相对于子项目的classpath路径，在IntelliJ中，resources是在classpath中的，如果只写名字应该是相对于子项目的resources目录才对啊，理论上。 请赐教 我查看了打包编译后的目录，确实是打进去了的，为什么通过只写文件名这种方式就访问不到呢？     

spark运行scala的jar包

   有人遇到过类似的问题吗？ 我的尝试： 当没Master节点的Worker进程，运行会报错，当开启了Master节点的Worker进程有时不会报错，但是会说内存不够，但是我觉得不是这个问题，也能得出一定的结果，但并不是预期的结果。 执行的命令：bin/spark-submit --master spark://node1:7077 --class cn.itcast.WordCount_Online --executor-memory 1g --total-executor-cores 1 ~/data/spark_chapter02-1.0-SNAPSHOT.jar /spark/test/words.txt /spark/test/out jar包是在idea中打包的，用的是scala语言，主要作用是词频统计 scala代码： ``` package cn.itcast import org.apache.spark.rdd.RDD import org.apache.spark.{SparkConf, SparkContext} object WordCount_Online { def main(args: Array[String]):Unit={ val sparkConf = new SparkConf().setAppName("WordCount_Online") val sparkContext = new SparkContext(sparkConf) val data : RDD[String] = sparkContext.textFile(args(0)) val words :RDD[String] = data.flatMap(_.split(" ")) val wordAndOne :RDD[(String,Int)] = words.map(x => (x,1)) val result :RDD[(String,Int)] = wordAndOne.reduceByKey(_+_) result.saveAsTextFile(args(1)) sparkContext.stop() } } ``` 我也做了很多尝试，希望懂的人可以交流一下

ssm框架demo遇到的问题

各位老哥们大家好，我是一名大二学生，自学Java一年半了，进步很慢，在ssm框架上遇到了问题，认识的人少，这个问题没人指点我，我很难再往后学习。 下面描述一下我遇到的问题吧：我比较抵触写jsp，所以从javaweb开始就尝试前后端分离，在学习ssm框架时，讲师用的都是jsp，我以为只要把springmvc的视图解析器中suffix配置成.html就行了，事情却没那么简单，项目一运行就报404，按理应该默认去找index.html，但是却直接报错，希望老哥们给我分析一下我哪里有错误。希望前辈能指导一下，谢谢了 ##

环境： maven3.0+springboot2.2.0 想做微服务调用使用feign，启动类添加@EnableDiscoveryClient和@EnableDiscoveryClient pom文件添加： ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>consumer</artifactId> <version>0.0.1-SNAPSHOT</version> <name>consumer</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> <version>2.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-openfeign-core</artifactId> <version>2.0.0.RC1</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> <version>2.0.0.RC1</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> ``` 如果不添加spring-cloud-openfeign-core，注解无法使用。 如果添加了他，启动项目时报错context找不到。 真心是无解了。。。。这springboot2.2.0怎么这么多坑

IDEA重复操作数据库的

在idea中进行mybaits插入操作时自己会重复的再做一次操作,以前用spring的时候也是,只要在测试类中进行测试就会重复操作数据库, maven工程下test,如何解决

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。 系统环境：java-1.8; mysql-5.1.62; IDEA 2019-1.4;SpringBoot 2.2.2; 2.pom文件： <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.2.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>cache</artifactId> <version>0.0.1-SNAPSHOT</version> <name>cache</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-cache</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.34</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> 3.配置文件  4.报错信息     

制作starter时报No qualifying bean of type 'org.beetl.ext.spring.BeetlSpringViewResolver' available:

我在制作SpringBoot自定义starter时，遇到了问题，即：在添加starter之后服务可以启动，但是没有起到配置作用。 具体代码如下： 目录结构  下面是配置类：   以及pom：  还有factories：  然后mvn clean install 但是当我加入其他项目时，发现尽管可以正常启动，但是并没有注入成功。 并不是ConditionOnProperty的问题，把它注释了也一样。 于是我写了一个Test：  运行了发现报错了： ``` org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.welfarezhu.billweb.BillWebApplicationTests': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.beetl.ext.spring.BeetlSpringViewResolver' available: expected at least 1 bean which qualifies as autowire candidate.

spring整合使用mybatis的接口，但使用时显示在spring容器内找不到dao的接口对象。

本来已经整合了spring和springmvc，然后我再添加了mybatis的依赖，数据库的配置等等。在test类里mybatis可以单独运作。但是和spring整合的时候就出现问题. 这是我的目录结构  我的dao中的类如下 ``` @Repository public interface IAccountDao { @Select("select * from account") List<Account> findAll(); @Insert("insert into account(name,money) values (#{name},#{money})") void saveAccount(Account account); } ``` service中的类如下 ``` @Service("accountService") public class AccountServiceImpl implements IAccountService { @Autowired private IAccountDao accountDao; @Override public List<Account> findAll() { System.out.println("findAll_service"); return accountDao.findAll(); } @Override public void saveAccount(Account account) { System.out.println("saveAccount_service"); accountDao.saveAccount(account); } } ``` 而且我的spring的配置文件已经按照教程中那样引入了mybatis的工厂什么的 ``` <?xml version="1.0" encoding="UTF-8"?> <beans 一堆约束省略了> <context:component-scan base-package="com.HSY"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 整合Mybatis--> <!-- 配置C3P0的连接池对象 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/ssm" /> <property name="username" value="root" /> <property name="password" value="123456" /> </bean> <!-- 配置SqlSession的工厂 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置扫描dao的包--> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.HSY.dao"/> </bean> </beans> ``` SqlMapConfig的数据库配置也配了，但是最后仍然报错 ``` beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.HSY.dao.IAccountDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} ``` 请问大神们怎么解决

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...

为啥国人偏爱Mybatis，而老外喜欢Hibernate/JPA呢？

关于SQL和ORM的争论，永远都不会终止，我也一直在思考这个问题。昨天又跟群里的小伙伴进行了一番讨论，感触还是有一些，于是就有了今天这篇文。 声明：本文不会下关于Mybatis和JPA两个持久层框架哪个更好这样的结论。只是摆事实，讲道理，所以，请各位看官勿喷。 一、事件起因 关于Mybatis和JPA孰优孰劣的问题，争论已经很多年了。一直也没有结论，毕竟每个人的喜好和习惯是大不相同的。我也看...

压测学习总结（1）——高并发性能指标：QPS、TPS、RT、吞吐量详解

一、QPS，每秒查询 QPS：Queries Per Second意思是“每秒查询率”，是一台服务器每秒能够相应的查询次数，是对一个特定的查询服务器在规定时间内所处理流量多少的衡量标准。互联网中，作为域名系统服务器的机器的性能经常用每秒查询率来衡量。 二、TPS，每秒事务 TPS：是TransactionsPerSecond的缩写，也就是事务数/秒。它是软件测试结果的测量单位。一个事务是指一...

Vue快速实现通用表单验证

本文开篇第一句话，想引用鲁迅先生《祝福》里的一句话，那便是：“我真傻，真的，我单单知道后端整天都是CRUD，我没想到前端整天都是Form表单”。这句话要从哪里说起呢？大概要从最近半个月的“全栈工程师”说起。项目上需要做一个城市配载的功能，顾名思义，就是通过框选和拖拽的方式在地图上完成配载。博主选择了前后端分离的方式，在这个过程中发现：首先，只要有依赖jQuery的组件，譬如Kendoui，即使使用...

面试官：关于Java性能优化，你有什么技巧

通过使用一些辅助性工具来找到程序中的瓶颈，然后就可以对瓶颈部分的代码进行优化。 一般有两种方案：即优化代码或更改设计方法。我们一般会选择后者，因为不去调用以下代码要比调用一些优化的代码更能提高程序的性能。而一个设计良好的程序能够精简代码，从而提高性能。 下面将提供一些在JAVA程序的设计和编码中，为了能够提高JAVA程序的性能，而经常采用的一些方法和技巧。 1．对象的生成和大小的调整。 J...

互联网公司分布式系统架构演进之路

介绍 分布式和集群的概念经常被搞混，现在一句话让你明白两者的区别。 分布式：一个业务拆分成多个子业务，部署在不同的服务器上 集群：同一个业务，部署在多个服务器上 例如：电商系统可以拆分成商品，订单，用户等子系统。这就是分布式，而为了应对并发，同时部署好几个用户系统，这就是集群 1 单应用架构 2 应用服务器和数据库服务器分离 单机负载越来越来，所以要将应用服务器和数据库服务器分离 3 应用服务...

GitHub 标星 1.6w+，我发现了一个宝藏项目，作为编程新手有福了！

大家好，我是 Rocky0429，一个最近老在 GitHub 上闲逛的蒟蒻… 特别惭愧的是，虽然我很早就知道 GitHub，但是学会逛 GitHub 的时间特别晚。当时一方面是因为菜，看着这种全是英文的东西难受，不知道该怎么去玩，另一方面是一直在搞 ACM，没有做一些工程类的项目，所以想当然的以为和 GitHub 也没什么关系（当然这种想法是错误的）。 后来自己花了一个星期看完了 Pyt...
