我有一个Spring引导项目,它引用一个外部模块来执行结果。
我已经在模块依赖项下添加了外部模块:
但是,当我运行Spring引导应用程序时,它会失败,并出现以下错误:
<代码>错误:(3, 16)Java:包实例不存在
customerLossPrediction
in the below source referencing to external module and call to this module fails even thing I added the module to project workspace and dependencies are added correctly.请帮忙!
package com.example.demo.service;
import examples.customerLossPrediction;
导入org.nd4j.linalg.api.ndarray.indarray;
导入org.springframework.web.multipart.multipartfile;
导入java.io.file;
导入java.io.ioexception;
@服务
公共类dl4jserviceimpl实现dl4jservice{
@重写
公共字符串fetchprediction(multipartfile文件)引发IOException、InterruptedException{
file convfile=新文件(file.getOriginalFileName());
文件.transferto(convfile);
indarray array=new customerlossprediction().generateoutput(convfile);
返回array.toString();
}
}

我认为发生这种情况是因为我试图从某种方式引用外部模块,或者另一个模块无法从弹簧引导模块引用?如果有人能澄清这一谜团,我将不胜感激:)
我已经在模块依赖项下添加了外部模块:
但是,当我运行Spring引导应用程序时,它会失败,并出现以下错误:
Error:(3, 16) java: package examples does not exist
CustomerLossPrediction在下面提到外部模块的源代码中,即使我将模块添加到项目工作区,对该模块的调用也会失败,并且依赖项也会正确添加。请帮忙!
package com.example.demo.service;
import examples.CustomerLossPrediction;
import org.nd4j.linalg.api.ndarray.INDArray;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.IOException;
@Service
public class DL4JServiceImpl implements DL4JService {
@Override
public String fetchPrediction(MultipartFile file) throws IOException, InterruptedException {
File convFile = new File( file.getOriginalFilename());
file.transferTo(convFile);
INDArray array = new CustomerLossPrediction().generateOutput(convFile);
return array.toString();
}
}
