我正在使用Spring Boot 2.X应用程序进行Spring

Batch，实际上我已经从git中检出了它的现有代码。在运行该应用程序时，由于以下错误而导致失败仅对我自己，而相同的代码对其他人也有效。

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.

APPLICATION FAILED TO START

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.

我在下面检查了

所有Spring组件均已使用@ Component，@ Service，@ Controller，@ Repository等正确注释。

还提供了@ComponentScan和@EnableAutoCOnfiguration。

尝试在声明中提供“ java.lang.String”。

码：
