借用之前cassandra学习建了user表，

user.java

@Table
public class User {

    @PrimaryKey
    private UUID id;

    private String userName;

    @Override
    public String toString() {
        return String.format("User[id=%s, userName='%s']", this.id,
                this.userName);
    }
}

userDao.java

@Repository
public class UserDao{
	@Autowired
	private CassandraTemplate cassandraTemplate; 
	
	public List<User> getAll() {
		return cassandraTemplate.select("SELECT ID, user_name FROM user", User.class);
		
	}  
}

UserController.java

@RestController
public class UserController {
	@Autowired
	private UserDao userDao;  
	@RequestMapping("/list")
	public List<User> list() {
		return userDao.getAll();
	}
}
