错误:(3, 27) java: 程序包com.netflix.appinfo不存在

1.问题描述

编译项目，报错

  1. 错误:(3, 27) java: 程序包com.netflix.appinfo不存在

2.问题分析

相关的包没有引用

3.问题解决

demo-eureka pom.xml 添加下面的内容，再次编译，错误消失

  1. <properties>
  2.     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  3.     <spring-cloud-netflix-eureka-server.version>2.1.0.RC2</spring-cloud-netflix-eureka-server.version>
  4. </properties>
  6. <dependency>
  7.     <groupId>org.springframework.cloud</groupId>
  8.     <artifactId>spring-cloud-netflix-eureka-server</artifactId>
  9.     <version>${spring-cloud-netflix-eureka-server.version}</version>
  10.     <scope>compile</scope>
  11. </dependency>

这样问题并没有彻底解决，会引发新的问题，解决办法参考问题-Maven: org.springframework.cloud:xx:unknown

错误-Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[]]

1.问题描述

解决了上面的错误之后，运行程序，报下面的错误

2.问题分析

报错信息中出现了 

  1. Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()

下面这个老哥的分析，原因如下

SpringBoot报错：java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;
Servlet-api 3.1.0 以及之后的版本中才有getVirtualServerName，确保项目中使用的是这个版本3.1.0以及之后，或者直接排除所有Servlet-api，使用SpringBoot内嵌的tomcat.

3.问题解决

打开模块设置

可以看到这里 servlet 的版本是 2.5，这里选中这个依赖，点击 - 移除

移除后再次运行项目，问题解决

问题-Maven: org.springframework.cloud:xx:unknown

1.问题描述

查看模块设置，出现 Maven: org.springframework.cloud:xx:unknown 错误

  1. 库有 'Maven: org.springframework.cloud:spring-cloud-starter:unknown' 有损坏的路径
  2. 库有 'Maven: org.springframework.cloud:spring-cloud-starter-netflix-eureka-server:unknown' 有损坏的路径

在右侧的 Maven 选项卡也存在同样问题

2.问题分析

org.springframework:spring-cloud-starter-netflix-eureka-client:unknown 的解决办法

原因很简单，是因为没有指定依赖的版本号（不知道为什么 SpringCloud 其他依赖都默认有版本号维护，但是这个没有，所以自己手动加一下）

3.问题解决

我参考了之前相同配置但无报错的 maven 引用情况，如下

4.测试结果

配置后，点击 Import Changes，问题解决

错误-无法解析符号 ‘log’

1.问题描述

2.问题分析

猜测是没有安装 Lombok 插件引起的

3.问题解决

安装 Lombok 插件后，问题解决

IntelliJ IDEA 2018.3 安装 Lombok 插件

4.扩展-相关问题

IntelliJ IDEA 2018.3 安装 Lombok 插件

错误-无法解析符号 ‘log’

引用 lombok 使用 log 提示找不到符号

错误-No active profile set, falling back to default profiles: default

1.问题描述

启动项目，控制台打印了下面的信息，然后程序就结束了

  1. 2021-03-09 21:13:45.487  INFO 121688 --- [           main] s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@7722c3c3: startup date [Tue Mar 09 21:13:45 CST 2021]; root of context hierarchy

  6. 进程已结束，退出代码 1

2.问题分析

查了很多解决方案，都没办法解决，最后请教杨老师，他说是还有些包没有引用。

再次分析了之前成功运行的项目，发现还需要引用一个父 pom 文件

3.问题解决

(1)新建 enta-parent.pom.xml

错误-无法解析符号 ‘lombok’

错误-The Tomcat connector configured to listen on port 8771 failed to start

1.问题描述

启动项目，控制台报下面的错误

  1. Description:
  3. The Tomcat connector configured to listen on port 8771 failed to start. The port may already be in use or the connector may be misconfigured.
  5. Action:
  7. Verify the connector's configuration, identify and stop any process that's listening on port 8771, or configure this application to listen on another port.

2.问题分析

这是端口被占用导致的

3.问题解决

(1)查看占用端口号的 PID-netstat -ano

(2)根据 PID 查询程序-tasklist | findstr "2864"

(3)结束程序-taskkill /f /t /im java.exe

4.测试结果

http://127.0.0.1:8771/

spring-boot-maven-plugin:unknown的完美解决方法

“插件的某个版本” <version>xxx</version> 从插件所在的文件路径里寻找
“插件所在路径”=maven仓库路径+<groupId>+<artifactId>。
找到很多版本后，一个一个去试。下图是我的路径举例。 

  1. D:\Program Files\Maven\Repository\org\springframework\boot\spring-boot-maven-plugin
