我正在尝试为每个列添加TTL,同时使用spring boot应用程序插入和更新数据.为此我使用spring-data-cassandra 1.1.3.RELEASE

为此,我编写了一个接口CustomTTLRepository:

@NoRepositoryBean

public interface CustomTTLRepository<T, ID extends Serializable> extends TypedIdCassandraRepository<T, ID> {

    <S extends T> S save(S s, int ttl);

}

实现CustomTTLRepositoryImpl:

@NoRepositoryBean

public class CustomTTLRepositoryImpl<T, ID extends Serializable> extends SimpleCassandraRepository<T, ID> implements CustomTTLRepository<T, ID> {

    public CustomTTLRepositoryImpl(CassandraEntityInformation<T, ID> metadata, CassandraTemplate template) {
         super(metadata, template);
         this.entityInformation = metadata;
         this.template = template;
    }   

    @Override
    public <S extends T> S save(S s, int ttl) {
        WriteOptions writeOptions=new WriteOptions();
        writeOptions.setTtl(ttl);
        return template.insert(s, writeOptions);
    }

}

但是,当我尝试部署此应用程序时,我收到以下错误:
