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

的身份访问sample.json
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());
}

所以 IFSClientTest 会运行fins,因为它们位于同一个包中。

问题吗
InventorySummaryResourceTest调用MockIFSClient尝试访问相同的代码,但现在它失败了

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>

问题

我对

做了什么改变
new File(getClass().getResource("/getInventoryAndPriceResponse.json").getPath())

以便可以从不同的模块访问

我将代码更改为

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