在基本springbatch程序中获取ConverterNotFoundException

Posted 2023-01-20

我正在尝试创建springboot批处理应用程序，并且在异常之下得到解决

org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.util.LinkedHashMap<?, ?>] to type [@org.springframework.lang.Nullable java.util.Map<java.lang.Class<?>, java.lang.Class<java.beans.PropertyEditor>>] for value 'org.springframework.batch.item.file.transform.Range[]=org.springframework.batch.item.file.transform.RangeArrayPropertyEditor'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [@org.springframework.lang.Nullable java.lang.Class<?>]

caused by 
org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [@org.springframework.lang.Nullable java.lang.Class<?>]

似乎在Spring尝试初始化org.springframework.beans.factory.config.CustomEditorConfigurer时出现此错误

我没有在我的代码中提供此bean定义。

以下是代码的关键部分：A.作业定义（以XML格式）：

<batch:job id="testBatchJob" job-repository="jobRepository">
    <batch:step id="step_test">
        <batch:tasklet  ref="createModifyTargetTable"/>
    </batch:step>
</batch:job>

B。其他定义（在Java中）

@Configuration
@ImportResource("classpath:database-config.xml","classpath:batchflows-config.xml")

public class SpringConfig 

    @Bean
    public PlatformTransactionManager transactionManager() 
        return new ResourcelessTransactionManager();
    

    @Bean
    public JobLauncher jobLauncher(JobRepository jobRepository) throws Exception 
        SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
        jobLauncher.setJobRepository(jobRepository);
        jobLauncher.afterPropertiesSet();
        return jobLauncher;
    

    @Bean
    public JobRepository jobRepository(@Qualifier("metadata-db") DataSource dataSource,
                                       PlatformTransactionManager transactionManager) throws Exception 
        JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
        factory.setDataSource(dataSource);
        factory.setDatabaseType("POSTGRES");
        factory.setTransactionManager(transactionManager);
        factory.afterPropertiesSet();
        return factory.getObject();
    

    @Bean
    public Tasklet createModifyTargetTable()
        return new CreateModifyTargetTable();
