I am working on spring batch with spring boot 2.X application, actually its existing code i am checked out from git. While running the application it fails due to below error only for me and same code is working for others.
s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'inputItemReader' defined in file [C:\Users\XYZ\git\main\batch\CBatchProcessing\target\classes\com\main\batchprocessing\batch\reader\InputItemReader.class]: Unsatisfied dependency expressed through **constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.lang.String' available: expected at least 1 bean which qualifies as autowire candidate.

Description:
**Parameter 0 of constructor in com.main.batchprocessing.batch.reader.InputItemReader required a bean of type 'java.lang.String' that could not be found.**
Action:
Consider defining a bean of type 'java.lang.String' in your configuration.
I have checked below
Code:
import java.util.Map;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.batch.core.ExitStatus;
import org.springframework.batch.core.StepExecution;
import org.springframework.batch.core.StepExecutionListener;
import org.springframework.batch.item.file.FlatFileItemReader;
import org.springframework.batch.item.file.mapping.JsonLineMapper;
import
org.springframework.batch.item.file.separator.JsonRecordSeparatorPolicy;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.core.io.FileSystemResource;
import org.springframework.stereotype.Component;
@Component
public class InputItemReader extends FlatFileItemReader<Map<String,
Object>> implements StepExecutionListener {
@Autowired
private InputFileHeaderValidator inputFileHeaderValidator;
@Autowired
private FileAuditService fileAuditService;
private final Logger log =
LoggerFactory.getLogger(InputItemReader.class);
private java.lang.String inputFilePath;
public InputItemReader(String inputFilePath) {
setLineMapper(new JsonLineMapper());
setRecordSeparatorPolicy(new JsonRecordSeparatorPolicy());
setResource(new FileSystemResource(inputFilePath));
this.inputFilePath = inputFilePath;
}
}
Since you do not provide the public default constructor and you added your own non-default constructor the instantiation will fail. I would suggest you to define the input file path as property like @Value("${inputFilePath}")
.
If you need further initialization in your bean define a void method and annotate it with @PostConstruct
and do the initialization within.
