spring-boot無法使用application.properties或者yml配置

1、確認pom.xml已配置

<build>
        <!--使application.properties生效-->
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>
        <!--end-->
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

2、刪除pom.xml以下配置

<packaging>pom</packaging>
