Spring batch Input resource must exist (reader is in 'strict' mode) error
提问by ttt
I use Spring Batch for parse csv file. It works great, when file in resource directory, but doesn't work from another place. I get suck error
我使用 Spring Batch 来解析 csv 文件。当文件在资源目录中时效果很好,但在其他地方不起作用。我得到错误
Caused by: java.lang.IllegalStateException: Input resource must exist (reader is in 'strict' mode): class path resource [c:/data/geodata1.csv]
My code
我的代码
spring.datasource:
driverClassName: org.h2.Driver
url: jdbc:h2:mem:mydb;MODE=Oracle
server:
port: 9001
geodata:
file: c:/data/geodata1.csv
@Value("${geodata.file}")
private String filePath;
@Bean
public FlatFileItemReader<Person> reader() {
FlatFileItemReader<Person> reader = new FlatFileItemReader<Person>();
reader.setResource(new ClassPathResource(filePath));
reader.setLineMapper(new DefaultLineMapper<Person>() {{
setLineTokenizer(new DelimitedLineTokenizer() {{
setNames(new String[] {"clientId", "longitude", "latitude", });
}});
setFieldSetMapper(new BeanWrapperFieldSetMapper<Person>() {{
setTargetType(Person.class);
}});
}});
return reader;
}
But this code works good
但是这段代码效果很好
File file = new File(filePath);

Just found the solution use org.springframework.core.io.UrlResource;
class instead of org.springframework.core.io.ClassPathResource;
刚刚发现解决方案使用org.springframework.core.io.UrlResource;
类而不是org.springframework.core.io.ClassPathResource;

I had find the same problem and i'd use org.springframework.core.io.FileSystemResource class like this: file: c:\data\geodata1.csv reader.setResource(new FileSystemResource(file));
我发现了同样的问题,我会像这样使用 org.springframework.core.io.FileSystemResource 类: file: c:\data\geodata1.csv reader.setResource(new FileSystemResource(file));
