07 构建Spring MVC应用程序-3

执行报错No qualifying bean of type 'spittr.data.SpittleRepository' available:
检查发现SpittleRepository是接口，并没有实现，书中遗漏，应该补齐；
注意要添加@Repository注解

@Repository
public class SpittleRepositoryDAO implements SpittleRepository {

    public SpittleRepositoryDAO() {

    }

    @Override
    public List<Spittle> findSpittles(long max, int count) {
        List<Spittle> spittles = new ArrayList<Spittle>();
        for (int i = 0; i < count; i++) {
            spittles.add(new Spittle("Spittle " + i, new Date()));
        }
        return spittles;
    }
}

执行程序后查看

点击Spittles进入另一个页面
