用Maven和Spring用参数设置热再加载

Question

我有一个maven生成的项目。这是我的pom.xml：

@mvn package -PLOCAL

java -jar -Dspring.profiles.active=rganeyev target/abacus-web-0.1.jar

当运行完全打包的应用程序时，开发人员工具将自动禁用。如果您的应用程序是从Java-JAR启动的，或者是从一个特殊的类加载器启动的，那么它就被认为是一个“生产应用程序”。

要使用热重加载，我不能使用java-jar，而只能使用mvn实用程序。我尝试运行mvn spring-boot:run-plocal-dspring.profiles.active=rganeyev，但它不使用属性文件并崩溃。热运行maven和使用我的属性文件？

嗨，尝试将配置文件定义添加到POM中。

<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
            <profiles>
                <profile>rganeyev</profile>
            </profiles>
        </configuration>
    </plugin>
</plugins>

而不是用个人资料来称呼它：

mvn spring-boot:run -Dspring-boot.run.profiles=rganeyev
