maven配置好了吗?可以尝试一下,右击项目->maven->download sources

把maven的资源目录下的org\springframework\boot\spring-boot-starter-parent删除,然后项目update一下

检查一下那个pom.xml文件中的parent,是如何来的,就是这个问题

Spring boot项目引入hive-jdbc依赖后报空指针异常?

1. 多模块的Spring boot项目,其中需要使用hbase和hive连接,一个是用于匹配数据,一个是写数据 2. 工程pom文件中没有引入hive-jdbc的依赖时,工程能够正常启动,但是访问接口流程时又找不到hive的驱动。报错如下:java.lang.ClassNotFoundException: org.apache.hive.jdbc.HiveDriver。所以还是要引hive-jdbc的依赖 3. 但是引入后工程启动空指针 ``` org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is java.lang.NullPointerException at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:137) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:536) ~[spring-context-4.3.7.RELEASE.jar:4.3.7.RELEASE] at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.refresh(EmbeddedWebApplicationContext.java:122) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:737) [spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:370) [spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:314) [spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1162) [spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1151) [spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at cn.xxt.data.collect.DataCollectApplication.main(DataCollectApplication.java:12) [classes/:?] Caused by: java.lang.NullPointerException at org.springframework.util.ReflectionUtils.invokeMethod(ReflectionUtils.java:216) ~[spring-core-4.3.7.RELEASE.jar:4.3.7.RELEASE] at org.springframework.util.ReflectionUtils.invokeMethod(ReflectionUtils.java:201) ~[spring-core-4.3.7.RELEASE.jar:4.3.7.RELEASE] at org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory$Jetty93SessionConfigurer.getSessionManager(JettyEmbeddedServletContainerFactory.java:1016) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory$Jetty93SessionConfigurer.configure(JettyEmbeddedServletContainerFactory.java:1001) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory.configureSession(JettyEmbeddedServletContainerFactory.java:376) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory.configureWebAppContext(JettyEmbeddedServletContainerFactory.java:370) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory.getEmbeddedServletContainer(JettyEmbeddedServletContainerFactory.java:174) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.createEmbeddedServletContainer(EmbeddedWebApplicationContext.java:164) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:134) ~[spring-boot-1.5.2.RELEASE.jar:1.5.2.RELEASE] ... 8 more ``` 4. 我的pom文件如下,有大神给看看啥原因吗? ``` <parent> <artifactId>demo-hbase</artifactId> <groupId>com.demo</groupId> <version>1.0.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>demo-hbase-common</artifactId> <dependencies> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-client</artifactId> </dependency> <dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase-client</artifactId> </dependency> <dependency> <groupId>org.apache.hive</groupId> <artifactId>hive-jdbc</artifactId> <exclusions> <exclusion> <groupId>org.eclipse.jetty.aggregate</groupId> <artifactId>jetty-all</artifactId> </exclusion> <exclusion> <groupId>org.apache.hive</groupId> <artifactId>hive-shims</artifactId> </exclusion> </exclusions> </dependency> </dependencies> ```

spring boot 工程启动报错

正学习使用spring boot,创建了web工程,按照教程的例子,创建了helloword工程,启动后正常,可以正常访问。 然后我添加了jpa和mysql的依赖,工程就起不来了,报错缺类,但是这个类明明在工程的maven库中啊。 我把别人网上的项目下载,然后导入到我的eclipse,启动时也要报这个相同的错误。 jdk1.8,maven3.5 ```

spring官网上面下载个demo,导入到idea里面怎么都启动不起来,说是找不到依赖

![图片说明](https://img-ask.csdn.net/upload/202003/23/1584970415_602006.jpg)![图片说明](https://img-ask.csdn.net/upload/202003/23/1584970421_451477.jpg) 从网上搜了很多答案都试了编还是不行,编译能通过,也不报红,就是启动的时候paring 就失败了, 换了个编译器eclipse 能启动起来,但是为啥idea就不行,我的其他项目导入到idea里面是没问题的

关于创建springboot项目,test测试类引包异常报错求解?

通过快速初始化工具创建springboot项目后,Test测试类提示导入包异常。eclipse和idea皆是如此。 ![图片说明](https://img-ask.csdn.net/upload/201809/27/1538016564_757754.png) idea的的问题可以通过手动导入idea安装目录lib文件夹下的junit-4.12.jar解决问题。但是eclipse受到导入junit只能解决org.junit.Test;和org.junit.runner.RunWith;的问题。至于org.springframework.boot.test.context.SpringBootTest;的@SpringBootTest仍然提示无效。求解?

maven 导入的版本跟实际的版本不符是什么问题?

![图片说明](https://img-ask.csdn.net/upload/201908/13/1565685860_404036.png) 我想导入的是2.53.1,但是导入的确是3.14.0 ``` <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.3.RELEASE</version> <relativePath/> </parent> ``` 这个里面就包含了3.14.0这个版本,去掉这段代码就可以导入2.53.1.不去掉就是导入父类的这个3.14.0,怎么才能覆盖父类的这个版本呢?

Eclipse 导入项目 出错 Maven

![图片说明](https://img-ask.csdn.net/upload/201711/02/1509610203_332108.png) ``` Archive for required library: 'G:/Project/Maven/repository/org/springframework/boot/spring-boot-test/1.5.7.RELEASE/spring-boot-test-1.5.7.RELEASE.jar' in project 'pcms-admin-portal' cannot be read or is not a valid ZIP file ``` 在导入项目后,有错误提示,如上。按照网上找到的,把这个对应的jar删了,再重新下,错误还在。试过直接下载jar,后面手动放在对应的文件夹,结果还是没变。也试过在.classpath文件(好像是这个?忘了,大概吧),找到对应的,删掉,结果仍然没变。 在试了上面的方法后,刷新过,重新导入过,重启Eclipse过,没变化。。。。 请问该怎么去掉这个错误提示呢?

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

为什么你不想学习?只想玩?人是如何一步一步废掉的

不知道是不是只有我这样子,还是你们也有过类似的经历。 上学的时候总有很多光辉历史,学年名列前茅,或者单科目大佬,但是虽然慢慢地长大了,你开始懈怠了,开始废掉了。。。 什么?你说不知道具体的情况是怎么样的? 我来告诉你: 你常常潜意识里或者心理觉得,自己真正的生活或者奋斗还没有开始。总是幻想着自己还拥有大把时间,还有无限的可能,自己还能逆风翻盘,只不是自己还没开始罢了,自己以后肯定会变得特别厉害...

当HR压你价,说你只值7K,你该怎么回答?

当HR压你价,说你只值7K时,你可以流畅地回答,记住,是流畅,不能犹豫。 礼貌地说:“7K是吗?了解了。嗯~其实我对贵司的面试官印象很好。只不过,现在我的手头上已经有一份11K的offer。来面试,主要也是自己对贵司挺有兴趣的,所以过来看看……”(未完) 这段话主要是陪HR互诈的同时,从公司兴趣,公司职员印象上,都给予对方正面的肯定,既能提升HR的好感度,又能让谈判气氛融洽,为后面的发挥留足空间。...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

《经典算法案例》01-08:如何使用质数设计扫雷(Minesweeper)游戏

我们都玩过Windows操作系统中的经典游戏扫雷(Minesweeper),如果把质数当作一颗雷,那么,表格中红色的数字哪些是雷(质数)?您能找出多少个呢?文中用列表的方式罗列了10000以内的自然数、质数(素数),6的倍数等,方便大家观察质数的分布规律及特性,以便对算法求解有指导意义。另外,判断质数是初学算法,理解算法重要性的一个非常好的案例。

一文带你入门Java Stream流,太强了

两个星期以前,就有读者强烈要求我写一篇 Java Stream 流的文章,我说市面上不是已经有很多了吗,结果你猜他怎么说:“就想看你写的啊!”你看你看,多么苍白的喜欢啊。那就“勉为其难”写一篇吧,嘻嘻。 单从“Stream”这个单词上来看,它似乎和 java.io 包下的 InputStream 和 OutputStream 有些关系。实际上呢,没毛关系。Java 8 新增的 Stream 是为...
