整體功能說明

前後臺可以對多個webSocket進行資料變更的傳播。支援心跳

1.建立專案

2.新建web目錄

新建web目錄存放前端靜態檔案

3.注入依賴

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.3.1.RELEASE</version>
        </dependency>
        <!--websocket連線需要使用到的包-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-websocket</artifactId>
            <version>2.3
 
.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <version>2.3.1.RELEASE</version>
            <scope>test</scope>
        </dependency>

靜態檔案打包（紅字）

    <build>
        <resources>
            <resource>
                <directory>src/main/web</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>**/**</include>
                </includes>
            </resource>
        </resources>
 

        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
