No qualifying bean of type [leanbizapps.monster.services.BatchService] found for dependency

Question

I'm trying to run the batch but I was not able to inject the batchservice into it.

BatchApplication.java

package leanbizapps.dexter;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.data.rest.RepositoryRestMvcAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.annotation.ComponentScan;

import leanbizapps.monster.config.SwaggerConfig;

@ComponentScan
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class,SwaggerConfig.class,
        WebMvcAutoConfiguration.class,RepositoryRestMvcAutoConfiguration.class })
 public class BatchApplication {

     public static void main(String[] args) throws Exception {
     SpringApplication app = new SpringApplication(BatchApplication.class);
     ConfigurableApplicationContext ctx = app.run(args);
}
}

LeaveAllocationJobConfiguration.java

package leanbizapps.dexter.jobs;
@Configuration
@EnableBatchProcessing
public class LeaveAllocationJobConfiguration {

@Autowired
private JobBuilderFactory jobs;

@Autowired
private StepBuilderFactory stepBuilderFactory;

@Autowired
private EntityManagerFactory entityManagerFactory;

@Autowired
private BatchService batchService;

@Bean
public ItemReader<LeaveSetting> reader() {
    JpaPagingItemReader<LeaveSetting> leaveSettingReader = new JpaPagingItemReader<LeaveSetting>();
    leaveSettingReader.setEntityManagerFactory(entityManagerFactory);
    leaveSettingReader.setQueryString("from LeaveSetting");
    return leaveSettingReader;
}

@Bean
public Job addLeaveAllocationJob() {
    return jobs.get("addLeaveAllocationJob").listener(protocolListener()).start(step()).build();
}

@Bean
public Step step() {
    
    return stepBuilderFactory.get("step").<LeaveSetting, Boolean> chunk(1).reader(reader()).processor(processor())
            .writer(writer()).build();
}


@Bean
public ItemWriter<? super Boolean> writer() {
    return new ItemWriter<Boolean>() {

        @Override
        public void write(List<? extends Boolean> items) throws Exception {
            System.out.println("Processing " + items);
            
        }
    };
}

@Bean
public ItemProcessor<LeaveSetting, Boolean> processor() {
    return new ItemProcessor<LeaveSetting, Boolean>() {
        @Override
        public Boolean process(LeaveSetting leavesetting) throws Exception {
            int count =0;
            while(count>0){
                LocalDateTime localDateTime = LocalDateTime.now();
                batchService.leaveBatch(localDateTime);
            }
            return true;
        }
        
    };
}

@Bean
public ProtocolListener protocolListener() {
    return new ProtocolListener();
}

}

When I run this code I'm getting no qualifier bean type error. No qualifying bean of type [leanbizapps.monster.services.BatchService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

How could I solve this issue?

Answer 1

@ComponentScan(basePackages={"leanbizapps.monster", "leanbizapps.dexter"})
public class BatchApplication {
// source code
}

Answer 2

You didn't provide your BatchService, but it appears to be in the package leanbizzapps.monster.services, while your main class resides in the leanbizzapps.dexter package.

Spring boot will automatically scan all subpackages, however, it will not scan other packages (like leanbizzapps.monster.services).

The solution is to restructure the application so that BatchApplication is in the parent package of all beans (so you could move it to the leanbizzapps package for example).

The alternative is to include the leanbizzapps.monster.services package in any @ComponentScan, for example on your main class:

@ComponentScan(basePackages = { "leanbizzapps.monster.services", "leanbizzapps.dexter" })
public class BatchApplication {
    // ...
}
