<实践>Voldemort与Objot集成的WAP高性能方案与简单实现（三）

3、以User为例进行CRU操作

Id.java //Model的父类，为了该死的JSTL我得加上get/set

public abstract class Id<T extends Id<T>> {

	@EncDec
	public long id;

	public long id() {
		return id;
	}

	@SuppressWarnings("unchecked")
	public T id(long id_) {
		id = id_;
		return (T)this;
	}

	public long getId() {
		return id;
	}

	public void setId(long id) {
		this.id = id;
	}
}

User.java //用户信息

public class User extends Id<User> {

	@EncDec
	public String name;

	@EncDec
	public int age;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}
}

DoUser.java //CRU操作，同时处理HTTP请求

public class DoUser extends Do {

	@Service
	@Transaction.Any //只是跳转用，没有数据操作
	public String create_() throws Exception {
		return "/create";
	}

	@Service
	public String create(String name, int age) throws Exception {
		User u = new User();
		u.name = name;
		u.age = age;
		data.put(u);
		return "redirect:/";
	}

	@Service
	@Transaction.Any
	public String update_(long id, ModelMap map) throws Exception {
		User u = data.get(User.class, id);
		map.put("user", u);
		return "/update";
	}

	@Service
	public String update(long id, String name, int age) throws Exception {
		User u = new User().id(id);
		u.name = name;
		u.age = age;
		data.put(u);
		return "redirect:/";
	}

	@Service
	public String get(long id, ModelMap map) throws Exception {
		User u = data.get(User.class, id);
		map.put("user", u);
		return "/index";
	}
}
