Java：如何从其他模块读取文件？

Question

我有一个包含多个Maven模块的项目

project/pom.xml
       /external_services/pom.xml
                         /ifs/pom.xml
                             /src/test/java/
                                           /MockIFSClient.java
                                           /IFSClientTest.java
                             /src/test/java/resources/sample.json
       /inventory/pom.xml
                 /business/pom.xml
                             /src/main/java/InventorySummary.java
                 /services/pom.xml
                             /src/main/java/InventorySummaryResource.java
                             /src/main/test/InventorySummaryResourceTest.java

MockIFSClient 访问sample.json为

try {
    inventoryPriceDetails = mapper.readValue(new File(getClass().getResource("/getInventoryAndPriceResponse.json").getPath()), new TypeReference<List<InventoryPriceDetail>>() {
    });
} catch (final IOException e) {
    throw new RuntimeException("could not read resource :" + e.getMessage());
}

因此 IFSClientTest 运行鳍，因为它们在同一包中。

问题？ 尝试访问相同代码的
InventorySummaryResourceTest调用MockIFSClient，但现在失败，因为

could not read resource :file:/Users/harith/IdeaProjects/inventory_api/external_services/ifs/target/ifs-1.0-SNAPSHOT-tests.jar!/sample.json (No such file or directory)

services / pom.xml 具有以下依赖性

<dependency>
    <groupId>com.org.project.external_services</groupId>
    <artifactId>ifs</artifactId>
    <version>${project.version}</version>
    <type>test-jar</type>
    <scope>test</scope>
</dependency>

题

我要做出什么改变

new File(getClass().getResource("/getInventoryAndPriceResponse.json").getPath())

这样也可以从不同的模块访问它

这个答案帮助我正确了

如何从Java中的类路径真正读取文本文件

我将代码更改为

inventoryPriceDetails = mapper.readValue(getClass().getResourceAsStream("/getInventoryAndPriceResponse.json"), new TypeReference<List<InventoryPriceDetail>>() {});
