springboot获取resource下文件

三种方式

一、

ClassPathResource classPathResource = new ClassPathResource("file/template/cpsp_check_account.xlsx");

InputStream inputStream = classPathResource.getInputStream();

二、

InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("file/template/cpsp_check_account.xlsx");

三、

InputStream inputStream = this.getClass().getResourceAsStream("/file/template/cpsp_check_account.xlsx");

pom文件中设置

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xlsx</include>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                    <include>**/*.yml</include>
                    <include>**/Dockerfile</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xlsx</include>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                    <include>**/*.yml</include>
                    <include>**/Dockerfile</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>
