springboot工程打包时将application.properties放在jar包外

1、pom文件配置

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-resources-plugin</artifactId>
				<version>2.5</version>
				<executions>
					<execution>
						<id>copy-resources</id>
						<phase>package</phase>
						<goals>
							<goal>copy-resources</goal>
						</goals>
						<configuration>
							<encoding>UTF-8</encoding>
							<outputDirectory>${project.released.directory}</outputDirectory>
							<resources>
								<resource>
									<directory>./src/main/resources</directory>
									<includes>
										<include>application.properties</include>
									</includes>
								</resource>
							</resources>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
</build>

2、Application.java添加注解

@PropertySource("file:application.properties")
