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application.properties找不到文件的错误。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
