spring - 由 : java. io.FileNotFoundException : class path resource [application. properties] 导致无法打开，因为它不存在

Question

我正在创建一个 Spring Boot Batch 应用程序。该批次从 postgres 加载数据并插入到 MongoDB 中。我已经编写了代码，但是在运行 spring boot 应用程序时，它显示了 application.properties 的错误找不到文件。以下是错误片段:

'Caused by: java.io.FileNotFoundException: class path resource [application.properties] cannot be opened because it does not exist'
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.example.batch.SpringBatchExample]; nested exception is java.io.FileNotFoundException: class path resource [application.properties] cannot be opened because it does not exist

以下是application.properties文件内容:

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=Test_Data

#logging
logging.level.org.springframework.data=DEBUG
logging.level.=ERROR
logging.level.com.mastercard.refdata.*=DEBUG


#By default, Spring runs all the job as soon as it has started its context.
spring.batch.job.enabled=false

#Chunk Size to save data
spring.chunk.size=200

#Postgres DATASOURCE
spring.datasource.url=jdbc:postgresql://localhost:5432/Company-Test
spring.datasource.username=postgres
spring.datasource.password=test123
spring.datasource.driver-class-name=org.postgresql.Driver

请让我知道为什么我会遇到这个问题？？

检查您的 application.properties 文件是否在资源目录中，如下图所示:

如果您将 application.properties 保存到其他文件夹(例如 config)，如下图所示，然后配置您的 pom.xml 以下代码:

<build>
<resources>
    <resource>
        <directory>config</directory>
        <targetPath>${project.build.outputDirectory}</targetPath>
        <includes>
            <include>application.properties</include>
        </includes>
    </resource>
  </resources>
</build>
