二.錯誤原因

因為沒有正式環境的入口類,項目結構如下:

repackage failed: Unable to find main class

pom.xml檔案的配置資訊如下:

三.解決方案1

pom.xml檔案的中指定入口類,代碼如下

com.qfx.App

如圖

四.解決方案2

去掉配置資訊中spring熱部署的配置，如圖

五.解決方案3

修改pom.xml配置檔案内容如下,添加一個标簽，代碼如下

<build>

    <finalName>test</finalName>

    <pluginManagement>

        <plugins>

            <plugin>

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

                <artifactId>spring-boot-maven-plugin</artifactId>

                <dependencies>

                    <!-- spring熱部署 -->

                    <dependency>

                        <groupId>org.springframework</groupId>

                        <artifactId>springloaded</artifactId>

                        <version>1.2.8.RELEASE</version>

                    </dependency>

                </dependencies>

            </plugin>

        </plugins>

    </pluginManagement>

</build>           

六.再次執行 Maven install,一切正常（企業架構源碼可以加求球：三五三六二四七二五九）
