IDEA maven 打包配置文件找不到的解决方案

pom中添加：

<resources>
            <resource>
                <directory>src/main/resources/</directory>
                <filtering>true</filtering>
                <includes>
                    <include>**/*.properties</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources/</directory>
                <filtering>false</filtering>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>

resource的filtering属性用来表示资源文件中的占位符是否需要被替换，true为需要替换。

在idea下直接运行：

Properties properties = new Properties();
InputStream in = PropertiesUtils.class.getClassLoader().getResourceAsStream("./application.properties");
properties.load(in);

maven 打包运行

Properties properties = new Properties();
InputStream in = PropertiesUtils.class.getClassLoader().getResourceAsStream("application.properties");
properties.load(in);
