• You aren‘t using a compiler supported by lombok, so lombok will not work and has been disabled.
    Preferences | Build, Execution, Deployment | Compiler
    在User-local build process VM options (overrides Shared options):前面增加-Djps.track.ap.dependencies=false
  • @Slf4j找不到log
    Preferences | Build, Execution, Deployment | Compiler | Annotation Processors
    勾选Enable annotation processing
    重启idea
  • pom.xml不可用
    Preferences | Build, Execution, Deployment | Build Tools | Maven | Ignored Files
    勾销选中对应我的项目的pom.xml
  • JDK isn't specified for module '***'
    删除.idea而后刷新一下即可
  • Error:(28, 5) java: No property named "**" exists in source parameter(s). Did you mean "null"?
  • mapstruct疏忽了所有的属性，返回空的对象
    谬误解释：该谬误是应用mapstruct和lombok联合应用时产生的谬误，mapstruct在生成转换代码时找不到属性
    谬误剖析：起因是因为在生成转换代码时lombok还没有生成setter、getter相应办法，所以找不到属性
    解决办法：在pom.xml中调整程序lombok放在mapstruct后面编译

  • Web server failed to start. Port 8080 was already in use.
    停掉占用端口的其余Web server，也能够应用上面办法
    Mac零碎终端执行

    # 查找8080端口占用pidlsof -i tcp:8080# `kill`掉kill 6095

  • Maven创立的Module不能应用依赖库
    IDEA -> Preferences... -> Build,... -> Maven -> Ignored Files -> 勾掉.../pom.xml

  • main/java文件不能创立Java文件
    右击java -> Mark Directory as -> Sources Root
    Process terminated
    在报错的左侧栏里点击我的项目名查看谬误起因并解决
    解决：中文门路导致

  • Error:(28,57) java: -source 1.5 中不反对 diamond 运算符
    pom.xml中指定以后应用的jdk版本

    <properties>  <maven.compiler.source>1.8</maven.compiler.source>  <maven.compiler.target>1.8</maven.compiler.target>   <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion></properties>
  • Mac零碎idea集成Tomcat出错
    Error running 'Tomcat 9.0.34':Unable to open debugger port (127.0.0.1:xxxxx):java.net.SocketException "Socket closed"
    端口号被占用：调整端口号Startup/Connection -> Debug -> Port
    其余起因：Tomcat装置门路不对导致
