# 实验一

1. 通过IntelliJ IDEA的Spring Initializr向导创建Spring Boot项目

2. 添加两个功能模块：Spring MVC、lombok

3. 添加阿里云镜像仓库作为项目maven仓库；

   > 在pom.xml中添加以下配置

    ```xml
        <repositories>
            <repository>
                <id>maven-ali</id>
                <url>http://maven.aliyun.com/nexus/content/groups/public//</url>
            </repository>
        </repositories>
    ```

4. 解释项目pom.xml文件中主要标签的意义；

    ```xml
    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
        <!--Declares to which version of project descriptor this POM conforms.-->
        <modelVersion>4.0.0</modelVersion>
        <!--指定父项目-->
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.2.5.RELEASE</version>
            <relativePath/> <!-- lookup parent from repository -->
        </parent>
        <groupId>com.experiment</groupId>
        <artifactId>demo1</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <name>demo1</name>
        <description>Demo project for Spring Boot</description>
        <!--指定远程仓库-->
        <repositories>
            <repository>
                <id>maven-ali</id>
                <url>http://maven.aliyun.com/nexus/content/groups/public//</url>
            </repository>
        </repositories>
        <!--变量-->
        <properties>
            <!--指定编译所用jdk版本-->
            <java.version>1.8</java.version>
        </properties>
        <!--依赖-->
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>

            <dependency>

            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>

                    </exclusion>
                </exclusions>
            </dependency>
        </dependencies>
        <!--配置打包插件-->
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

    </project>

    ```

5. 配置**jetty**或**undertow**作为Spring Boot应用程序的默认Servlet容器；

    > 修改pom.xml中以下代码

    ```xml
            <!--指定web容器使用jetty-->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-jetty</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
                <!--移除tomcat容器-->
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-starter-tomcat</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
    ```

6. 添加一个简单的Spring Mvc控制器组件，用于测试，如下图：

	![image-20200325213507558](https://gitee.com/kevinsoft/spring_boot_experiment_1/raw/master/%E6%88%AA%E5%9B%BE/image-20200325213507558.png)

7. 定义一个CommandLineRunner的Bean，用于检查Spring Boot应用程序启动完成后在Spring IoC容器中注册的所有Bean。如下图：

	![image-20200325214126612](https://gitee.com/kevinsoft/spring_boot_experiment_1/raw/master/%E6%88%AA%E5%9B%BE/image-20200325214126612.png)

8. 编写一个简单的单完测试。如下图：

	![image-20200325215229964](https://gitee.com/kevinsoft/spring_boot_experiment_1/raw/master/%E6%88%AA%E5%9B%BE/image-20200325215229964.png)

9. 使用IntelliJ IDEA的HTTP Client工具测试控制器端口

	![image-20200325215401704](https://gitee.com/kevinsoft/spring_boot_experiment_1/raw/master/%E6%88%AA%E5%9B%BE/image-20200325215401704.png)

10. 在命令行中使用spring-boot插件运行Spring Boot应用程序，并把嵌入式Servlet容器的默认端口8080改为9090

    ```shell
    mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Ddebug -Dserver.port=9090"
    ```

    ![image-20200325221001500](https://gitee.com/kevinsoft/spring_boot_experiment_1/raw/master/%E6%88%AA%E5%9B%BE/image-20200325221001500.png)

11. 在属性文件中配置Spring Boot应用程序以debug模式运行。

    > application.yml中配置

    ```yaml
    debug: true
    ```

12. 在命令行中编译、打包Spring Boot应用程序。

    ```shell
    mvn package
    ```

13. 在命令行中使用java命令运行Spring Boot应用程序的Jar文件。

    ```shell
    java -jar target/demo1-0.0.1-SNAPSHOT.jar
    ```

    ![image-20200325220600784](https://gitee.com/kevinsoft/spring_boot_experiment_1/raw/master/%E6%88%AA%E5%9B%BE/image-20200325220600784.png)

14. 在命令行中使用java命令运行Spring Boot应用程序的Jar文件，带参数改变嵌入式Servlet容器的默认端口8080改为9090。

    ```shell
    java -jar demo1-0.0.1-SNAPSHOT.jar --server.port=9090
    ```
