Quarkus篇入门创建项目搭建debug环境_Java教程

前言

在学习一个新的框架技术前，肯定要先来一套hello word，搭建基本的运行环境和调试环境。

先来创建一个Quarkus的应用

搭建Quarkus项目

下面介绍三种创建Quarkus项目的方式

纯手工方式

1、创建maven工程，这个不多赘述，是个java程序员都会的

2、添加Quarkus依赖，下面贴出基本的依赖

				?

									<properties>

									        <quarkus-plugin.version>1.6.0.Final</quarkus-plugin.version>

									        <quarkus.platform.version>1.6.0.Final</quarkus.platform.version>

									        <surefire-plugin.version>2.22.1</surefire-plugin.version>

									        <compiler-plugin.version>3.8.0</compiler-plugin.version>

									        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

									        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

									    </properties>

									    <dependencyManagement>

									        <dependencies>

									            <dependency>

									                <groupId>io.quarkus</groupId>

									                <artifactId>quarkus-bom</artifactId>

									                <version>${quarkus.platform.version}</version>

									                <scope>import</scope>

									                <type>pom</type>

									            </dependency>

									        </dependencies>

									    </dependencyManagement>

									    <dependencies>

									        <dependency>

									            <groupId>io.quarkus</groupId>

									            <artifactId>quarkus-resteasy-jsonb</artifactId>

									        </dependency>

									        <!-- Testing: -->

									        <dependency>

									            <groupId>io.quarkus</groupId>

									            <artifactId>quarkus-junit5</artifactId>

									            <scope>test</scope>

									        </dependency>

									        <dependency>

									            <groupId>io.rest-assured</groupId>

									            <artifactId>rest-assured</artifactId>

									            <scope>test</scope>

									        </dependency>

									    </dependencies>

									    <build>

									        <plugins>

									            <plugin>

									                <groupId>org.apache.maven.plugins</groupId>

									                <artifactId>maven-compiler-plugin</artifactId>

									                <version>${compiler-plugin.version}</version>

									                <configuration>

									                    <source>1.8</source>

									                    <target>1.8</target>

									                    <!-- the parameters=true option is critical so that RESTEasy works fine -->

									                    <parameters>true</parameters>

									                </configuration>

									            </plugin>

									            <plugin>

									                <!-- you need this specific version to integrate with the other build helpers -->

									                <artifactId>maven-surefire-plugin</artifactId>

									                <version>${surefire-plugin.version}</version>

									                <configuration>

									                    <systemPropertyVariables>

									                        <java.util.logging.manager>org.jboss.logmanager.LogManager</java.util.logging.manager>

									                        <maven.home>${maven.home}</maven.home>

									                    </systemPropertyVariables>

									                </configuration>

									            </plugin>

									            <plugin>

									                <!-- This is what injects the magic Quarkus bytecode -->

									                <groupId>io.quarkus</groupId>

									                <artifactId>quarkus-maven-plugin</artifactId>

									                <version>${quarkus-plugin.version}</version>

									                <executions>

									                    <execution>

									                        <goals>

									                            <goal>build</goal>

									                        </goals>

									                    </execution>

									                </executions>

									            </plugin>

									        </plugins>

									    </build>

官网装配器方式

地址：https://code.quarkus.io/

用法和spring的https://start.spring.io/一样。填好你的maven基础信息，选好依赖就可以下载工程了

IDEA方式

IDEA里已经支持创建Quarkus项目了，和spring boot的原理一样，也是基于https://code.quarkus.io/来的，所以操作的方式和网页上一样，如：

Quarkus篇入门创建项目搭建debug环境

编写第一个Quarkus接口

				?

									@Produces(MediaType.TEXT_PLAIN)

									@Path("/hello")

									public class HelloResource {

									    @GET

									    @Path("/{name}")

									    public String hello(@PathParam("name") String name) {

									        return "hello" + name;

									    }

									}

Quarkus基于标准的jax-rs规范来写web的，当然，它也扩展了spring web的@Controller的方式，这个后面会介绍

启动你的应用并调试

1、通过运行 mvn quarkus:dev，可以启动应用，启动应用后，会发现打印了：

Listening for transport dt_socket at address: 5005

说明开启了5005调试端口，在IDEA中，可以通过

run-》Attach to process

来直接连接这个端口进行调试

2、可以新建一个main方法，直接debug模式启动，来进行运行和调试，如：

				?

									@QuarkusMain

									public class Main {

									    public static void main(String ... args) {

									        Quarkus.run(args);

									    }

									}
