这段代码是一个 Java 方法，返回一个 List<DormBuild> 对象。它的功能是从数据库中查询所有的 DormBuild 对象，但只返回每个对象的 dormbuild_id 属性，而不是所有属性。具体来说，它使用 MyBatis-Plus 框架中的 ...

@Override public List<?> homePageNotice() { QueryWrapper<Notice> qw = new QueryWrapper<>(); qw.orderByDesc("release_time"); List<Notice> noticeList = noticeMapper.selectList(qw); return noticeList; }

具体实现是通过使用 MyBatis-Plus 框架提供的 QueryWrapper 类来构建查询条件，并按照 release_time 字段降序排序，然后通过调用 noticeMapper 的 selectList 方法来执行查询，最后将查询结果返回。其中，返回类型...

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?

List<LoanEntity> loanEntityList = entityContext.executeTaskletService(strList, map); // 调用 ABLoanEntity4Tasklet 处理业务 entityContext.setTaskletService(context.getBean(ABLoanEntity4Tasklet....

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 ...

根据您提供的三个类，我认为您需要实现的接口应该是OrderService，以下是基于您提供的类实现的接口方法： import java.util.ArrayList; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Map; public class OrderServiceImpl implements OrderService { private Map<String, Order> orders = new HashMap<>(); @Override public void addOrder(String Id, Date createTime, List<Dish> dishes) { User user = new User("1", new Date(), new Date(), "username", "password"); List<OrderItem> items = new ArrayList<>(); for (Dish dish : dishes) { items.add(new OrderItem(dish, 1)); } Order order = new Order(Id, createTime, createTime, user, items, 0); orders.put(Id, order); } @Override public void deleteOrder(String Id) { orders.remove(Id); } @Override public void updateOrder(String Id, Date updateTime, List<Dish> dishes) { Order order = orders.get(Id); List<OrderItem> items = new ArrayList<>(); for (Dish dish : dishes) { items.add(new OrderItem(dish, 1)); } order.setItems(items); order.setUpdateTime(updateTime); orders.put(Id, order); } @Override public List<Order> queryOrder(String Id) { List<Order> result = new ArrayList<>(); if (orders.containsKey(Id)) { result.add(orders.get(Id)); } return result; } @Override public List<Order> queryAllOrders() { return new ArrayList<>(orders.values()); } } public class OrderItem extends BaseEntity { private Dish dish; private int quantity; // 省略 getter 和 setter 方法 public OrderItem(String id,Date createTime,Date updateTime,Dish dish,int quantity) { super(id,createTime,updateTime); this.dish=dish; this.quantity=quantity; }请基于四个类帮我实现接口的方法

List<OrderItem> items = new ArrayList<>(); for (Dish dish : dishes) { items.add(new OrderItem(dish, 1)); } Order order = new Order(id, createTime, createTime, user, items, 0); orders.put(id, ...

@Override public PageInfo<Auction> findAllAuction(Auction auction, int pageNum, int pageSize) { List<Auction> auctionList=new ArrayList<>(); PageHelper.startPage(pageNum,pageSize); if(auction==null){//如果条件为空 auctionList=auctionMapper2.findAllAuction(); }else { auctionList = auctionMapper2.findAllAuction2(auction); } PageInfo<Auction> pageInfo=new PageInfo<>(auctionList); return pageInfo; } @Override public Auction findAuctionById(int auctionid) { return auctionMapper2.findAuctionById(auctionid); } @Override public List<UserAndRecord> findAuctionAndUser(int auctionid) { return userAndRecordMapper.findAuctionAndUser(auctionid); } }这段代码是什么意思

第一个方法是findAllAuction，它接收一个Auction类型的参数和两个int类型的参数pageNum和pageSize，它会根据条件查询出数据库中的Auction表中满足条件的所有数据，并返回一个由PageInfo包装过的Auction类型的List。...
