java – Spring-Batch代理类不能转换为Class？

我有一个春季批量@Job定义.但是在运行它时(在tomcat中),由于com.sun.proxy,我得到了一个ClassCastException.$Proxy.

为什么会出现这种情况？以下摘录可能有什么问题？

@service
public class Jobservice {
    @Autowired
    private JobLauncher launcher;

    public void run() {
        Job job = jobRegistry.getJob("jobname");
        launcher.run(job,params); //line 59
    }
}


@Configuration
@EnableBatchProcessing(modular = truE)
public class JobConfig {
    @Bean
    @JobScope
    public MultiresourceItemReader<>(); ...="" return="" itemreader;="" }="" @bean="" public="" jobscope="" jobscope()="" {="" return="" new="" jobscope();="" }="" }="">

结果：

java.lang.ClassCastException: com.sun.proxy.$Proxy135 cAnnot be cast to org.springframework.batch.item.file.MultiresourceItemReader
