Quarkus很酷，但这些错误一点不酷 :(
学习内容参考
https://developer.ibm.com/zh/articles/j-use-quarkus-to-develop-kubernetes-native-java-application/
https://redhat-developer-demos.github.io/quarkus-tutorial/quarkus-tutorial/setup.html
时隔多年又开始研究程序......
0.一些基本操作
- 生成应用
mvn "io.quarkus:quarkus-maven-plugin:0.27.0.Final:create" -DprojectGroupId=io.vividcode -DprojectArtifactId=quarkus-demo -DclassName="io.vividcode.quarkus.ExampleResource" -Dpath="/example"
不同的版本会报错误，1.4.2的发现不行，建立出来的pom.xml有问题
因为要尝试部署到kubernetes,所以需要用新一点的版本。
mvn io.quarkus:quarkus-maven-plugin:1.6.0.Final:create -DprojectGroupId=io.vividcode -DprojectArtifactId=quarkus-sample -DclassName="io.vividcode.quarkus.ExampleResource" -Dpath="/example"
- list extension
mvnw quarkus:list-extensions [INFO] Scanning for projects... [INFO] [INFO] --------------------< io.vividcode:quarkus-starter >-------------------- [INFO] Building quarkus-starter 1.0-SNAPSHOT [INFO] --------------------------------[ jar ]--------------------------------- [INFO] [INFO] --- quarkus-maven-plugin:0.27.0:list-extensions (default-cli) @ quarkus-starter --- Downloading from central: https://repo.maven.apache.org/maven2/io/quarkus/quarkus-bom/0.27.0/quarkus-bom-0.27.0.json Current Quarkus extensions available: Quarkus - Core quarkus-core ArC quarkus-arc Quarkus - Caffeine - Runtime quarkus-caffeine JAXB quarkus-jaxb Jackson quarkus-jackson ....
- 添加extension
mvnw quarkus:add-extension -Dextensions=quarkus-spring-web,quarkus-spring-data-jpa
mvnw quarkus:add-extension -Dextensions=quarkus-kubernetes,quarkus-container-image-jib
1.mysql在windows上的安装以及找回密码
在官网下载并解压64位版本，然后在根目录下加入my.ini文件
[mysqld] basedir=D:\mysql-8.0.21-winx64\ datadir=D:\mysql-8.0.21-winx64\data
然后
mysqld --initialize mysqld --install mysql8.0 net start mysql8.0 mysql -u root -p
通过mysql一连，发现没密码了，接着做下一步
net stop mysql8.0 mysqld --shared-memory --skip-grant-tables mysql mysql>FLUSH PRIVILEGES mysql>ALTER USER 'root'@'localhost' IDENTIFIED BY 'welcome1' mysql>quit
把密码刷成 welcome1,然后登录
mysql> create database quarkus; mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | quarkus | | sys | +--------------------+ 5 rows in set (0.00 sec)
2.通过JPA连接数据库时的报错
mvn compile quarkus:dev ....... mysql The server time zone value '?й???????' is unrecognized or represents more than one time zone. ........
需要修改application.properties文件，在url后面添加一串东西
quarkus.datasource.url = jdbc:mysql://localhost:3306/quarkus?serverTimezone=UTC&characterEncoding=utf-8 quarkus.datasource.driver = com.mysql.cj.jdbc.Driver quarkus.datasource.username = root quarkus.datasource.password = welcome1 quarkus.hibernate-orm.dialect = org.hibernate.dialect.MySQL8Dialect quarkus.hibernate-orm.dialect.storage-engine = InnoDB quarkus.hibernate-orm.database.generation = drop-and-create
3.基于CURL命令POST数据插入数据库
按照官方文档，无耐怎么搞都是出错。
curl -H "Content-Type:application/json" -X POST --data '{"name":"Banana","price":2}' http://localhost:8080/product
在postman上倒是成功了，目前没发现为啥命令行不行
4.windows 10上的native build
按照文档，装完vs_BuildTools.exe，vc++ 2017, windows kit
装完Graalvm,修改完JAVA_HOME等环境变量，然后进入项目目录
call "d:Program Files (x86)Microsoft Visual Studio2017BuildToolsVCAuxiliaryBuildvcvars64.bat" && mvn package -Pnative
然后
[INFO] [io.quarkus.deployment.pkg.steps.NativeImageBuildStep] Running Quarkus native-image plugin on OpenJDK 64-Bit Server VM GraalVM CE 20.1.0 [INFO] [io.quarkus.deployment.pkg.steps.NativeImageBuildStep] D:graalvm-ce-java8-20.1.0in ative-image.cmd -J-Dsun.nio.ch.maxUpdateArraySize=100 -J-Djava.util.logging.manager=org.jboss.logmanager.LogManager -J-DCoordinatorEnvironmentBean.transactionStatusManagerEnable=false -J-Dvertx.logger-delegate-factory-class-name=io.quarkus.vertx.core.runtime.VertxLogDelegateFactory -J-Dvertx.disableDnsResolver=true -J-Dio.netty.leakDetection.level=DISABLED -J-Dio.netty.allocator.maxOrder=1 --initialize-at-build-time= -H:InitialCollectionPolicy=com.oracle.svm.core.genscavenge.CollectionPolicy$BySpaceAndTime -jar quarkus-starter-1.0-SNAPSHOT-runner.jar -J-Djava.util.concurrent.ForkJoinPool.common.parallelism=1 -H:FallbackThreshold=0 -H:+ReportExceptionStackTraces -H:+AddAllCharsets -H:EnableURLProtocols=http,https --enable-all-security-services -H:+JNI -H:-UseServiceLoaderFeature -H:+StackTrace quarkus-starter-1.0-SNAPSHOT-runner [quarkus-starter-1.0-SNAPSHOT-runner:17844] classlist: 14,115.85 ms, 2.46 GB [quarkus-starter-1.0-SNAPSHOT-runner:17844] setup: 1,704.89 ms, 2.46 GB Error: Unable to detect supported WINDOWS native software development toolchain. com.oracle.svm.core.util.UserError$UserException: Unable to detect supported WINDOWS native software development toolchain. at com.oracle.svm.core.util.UserError.abort(UserError.java:68) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker.<init>(CCompilerInvoker.java:72) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker$WindowsCCompilerInvoker.<init>(CCompilerInvoker.java:93) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker.create(CCompilerInvoker.java:84) at com.oracle.svm.hosted.NativeImageGenerator.setupNativeImage(NativeImageGenerator.java:851) at com.oracle.svm.hosted.NativeImageGenerator.doRun(NativeImageGenerator.java:536) at com.oracle.svm.hosted.NativeImageGenerator.lambda$run$0(NativeImageGenerator.java:451) at java.util.concurrent.ForkJoinTask$AdaptedRunnableAction.exec(ForkJoinTask.java:1386) at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:289) at java.util.concurrent.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1056) at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1692) at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157) Error: Image build request failed with exit status 1 [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 43.576 s [INFO] Finished at: 2020-08-10T23:26:43+08:00

尝试切换字符集chcp 437等步骤，没有生效，暂时没有解决。
5.生成镜像部署
要用docker了，因为之前在windows上用docker遇到的各种坑，果断切换成rhel,又是一段狂装机。
按照文档，需要在application.properties里面加入
quarkus.container-image.registry=quay.io quarkus.container-image.group=jnie quarkus.container-image.name=quarkus-sample quarkus.container-image.tag=1.0-SNAPSHOT quarkus.kubernetes.service-type=load-balancer
然后运行
mvn clean package -DskipTests -Dquarkus.container-image.push=true
[WARNING] [io.quarkus.container.image.jib.deployment.JibProcessor] Base image 'fabric8/java-alpine-openjdk11-jre' does not use a specific image digest - build may not be reproducible [INFO] [io.quarkus.container.image.jib.deployment.JibProcessor] LogEvent [level=INFO, message=Docker config auths section defines credentials for quay.io] [INFO] [io.quarkus.container.image.jib.deployment.JibProcessor] LogEvent [level=LIFECYCLE, message=Using credentials from Docker config (/root/.docker/config.json) for quay.io/jnie/quarkus-sample:1.0-SNAPSHOT] [INFO] [io.quarkus.kubernetes.deployment.KubernetesProcessor] Generated the Kubernetes manifests: 'kubernetes.json,kubernetes.yml' in '/root/lab/quarkus-sample/target/kubernetes' [INFO] [io.quarkus.container.image.jib.deployment.JibProcessor] The base image requires auth.

里面调用了fabric类，发现问题是连接不上，
然后换一种模式构建镜像，Dockerfile.jvm是在安装的时候自动生成的。
docker build -f src/main/docker/Dockerfile.jvm -t quay.io/jnie/vividcode/quarkus-sample .
构建完成看一下
[root@registry quarkus-sample]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE quay.io/jnie/vividcode/quarkus-sample latest 5a6fb08704cf 10 seconds ago 549 MB registry.access.redhat.com/ubi8/ubi-minimal 8.1 91d23a64fdf2 4 months ago 107 MB
然后运行
[root@registry docker]# docker run -i --rm -p 8080:8080 quay.io/jnie/vividcode/quarkus-sample:latest exec java -Dquarkus.http.host=0.0.0.0 -Djava.util.logging.manager=org.jboss.logmanager.LogManager -XX:+ExitOnOutOfMemoryError -cp . -jar /deployments/app.jar __ ____ __ _____ ___ __ ____ ______ --/ __ / / / / _ | / _ / //_/ / / / __/ -/ /_/ / /_/ / __ |/ , _/ ,< / /_/ / --\___\_\____/_/ |_/_/|_/_/|_|\____/___/ 2020-08-11 09:14:13,165 INFO [io.quarkus] (main) quarkus-sample 1.0-SNAPSHOT on JVM (powered by Quarkus 1.6.1.Final) started in 1.704s.

测试成功。
还有各种大坑稍后逐步奉上...
