spring - 使用 Maven 和 Spring 设置带参数的热重载

Question

我有一个 Maven 生成的项目。这是我的 pom.xml:

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

我使用这个命令构建它:

@mvn package -PLOCAL

然后使用这个命令运行:

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

我有一个 src/main/resources/application-rganeyev.properties 文件，其中设置了我的本地属性。应用程序必须使用此文件才能正常工作。

它工作正常，构建和运行正常。问题是我不能使用热重载。 Documentation says :

Developer tools are automatically disabled when running a fully packaged application. If your application is launched from java -jar or if it is started from a special classloader, then it is considered a “production application”.

要使用热重载，我不能使用 java -jar，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。想运行 Maven 并使用我的属性文件吗？

您好，请尝试将配置文件定义添加到 POM。

<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>

然后用配置文件调用它:

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