不是这个意思,我给你看下我的代码: 这是我的泛型接口： @Component public interface TaskletService<T> { List<T> match(List<String> strList, Map<String,Object> map) throws ParseException; } 这是针对接口的策略实现类，有10个，我只列举三个： @Component public class ADLoanEntity4Tasklet implements TaskletService<LoanEntity> { @Override public List<LoanEntity> match(List<String> strList, Map<String, Object> map) throws ParseException { List<LoanEntity> list = new ArrayList<>(); return list; } } @Component public class ABLoanEntity4Tasklet implements TaskletService<LoanEntity> { @Override public List<LoanEntity> match(List<String> strList, Map<String, Object> map) throws ParseException { List<LoanEntity> list = new ArrayList<>(); return list; } } @Component public class ADLoanHisEntity4Tasklet implements TaskletService<LoanHisEntity> { @Override public List<LoanHisEntity> match(List<String> strList, Map<String, Object> map) throws ParseException { List<LoanHisEntity> list = new ArrayList<>(); return list; } } 这是Context类: @Component public class TaskletContext<T> { private TaskletService<T> taskletService; @Autowired public void setTaskletService(TaskletService<T> taskletService) { this.taskletService = taskletService; } public List<T> executeTaskletService(List<String> strList, Map<String,Object> map) throws ParseException { return taskletService.match(strList,map); } } 我现在想在main方法中去调用ADLoanEntity4Tasklet,ABLoanEntity4Tasklet,ADLoanHisEntity4Tasklet去处理不同的业务,请问该如何调用?

根据你提供的代码，你可以在 main 方法中创建 TaskletContext 对象，并使用 setTaskletService 方法来设置具体的实现类，然后调用 executeTaskletService 方法来执行相应的业务逻辑。以下是一个示例的 ...

解释以下代码：@Service("addressService") public class AddressServiceImpl extends ServiceImpl<AddressDao, AddressEntity> implements AddressService { @Override public PageUtils queryPage(Map<String, Object> params) { Page<AddressEntity> page = this.selectPage( new Query<AddressEntity>(params).getPage(), new EntityWrapper<AddressEntity>() ); return new PageUtils(page); } @Override public PageUtils queryPage(Map<String, Object> params, Wrapper<AddressEntity> wrapper) { Page<AddressView> page =new Query<AddressView>(params).getPage(); page.setRecords(baseMapper.selectListView(page,wrapper)); PageUtils pageUtil = new PageUtils(page); return pageUtil; } @Override public List<AddressVO> selectListVO(Wrapper<AddressEntity> wrapper) { return baseMapper.selectListVO(wrapper); } @Override public AddressVO selectVO(Wrapper<AddressEntity> wrapper) { return baseMapper.selectVO(wrapper); } @Override public List<AddressView> selectListView(Wrapper<AddressEntity> wrapper) { return baseMapper.selectListView(wrapper); } @Override public AddressView selectView(Wrapper<AddressEntity> wrapper) { return baseMapper.selectView(wrapper); }

我把我现在的代码给你看下,报错的是:"Parameter 0 of method setTaskletService in com.uniinclusive.jxgfcs.taskletimpl.TaskletContext required a single bean, but 10 were found",代码内容如下: @Component public class TaskletContext<T> { private TaskletService<T> taskletService; @Autowired public void setTaskletService(TaskletService<T> taskletService) { this.taskletService = taskletService; } public List<T> executeTaskletService(List<String> strList, Map<String,Object> map) throws ParseException { return taskletService.match(strList,map); } } @Component public interface TaskletService<T> { List<T> match(List<String> strList, Map<String,Object> map) throws ParseException; } @Component public class ADLoanEntity4Tasklet implements TaskletService<LoanEntity> { @Override public List<LoanEntity> match(List<String> strList, Map<String, Object> map) throws ParseException { List<LoanEntity> list = new ArrayList<>(); return list; } } @Component public class AFFLoanEntity4Tasklet implements TaskletService<LoanEntity> { @Resource private LoanDao loanDao; //字符长度 private final int strLength = 22; @Override public List<LoanEntity> match(List<String> strList, Map<String,Object> map) throws ParseException { List<LoanEntity> list = new ArrayList<>(); return list; } }

根据你提供的代码，出现报错的原因是在 TaskletContext 类的 setTaskletService 方法中存在多个符合条件的 TaskletService<T> bean。为了解决这个问题，你可以尝试以下几种方法： 1. 使用 @Qualifier ...
