FinalDb
建库
[java] view
plaincopyprint?
-
FinalDb db = FinalDb.create(context, "mytest.db", true);
有实体bean
[java] view
plaincopyprint?
-
@Table(name = "user")
-
public class User {
-
private int id;
-
private String name;
-
private String email;
-
private Date registerDate;
-
private Double money;
-
-
-
public int getId() {
-
return id;
-
}
-
public void setId(int id) {
-
this.id = id;
-
}
-
public String getName() {
-
return name;
-
}
-
public void setName(String name) {
-
this.name = name;
-
}
-
public String getEmail() {
-
return email;
-
}
-
public void setEmail(String email) {
-
this.email = email;
-
}
-
public Date getRegisterDate() {
-
return registerDate;
-
}
-
public void setRegisterDate(Date registerDate) {
-
this.registerDate = registerDate;
-
}
-
public Double getMoney() {
-
return money;
-
}
-
public void setMoney(Double money) {
-
this.money = money;
-
}
-
}
建表
[java] view
plaincopyprint?
-
db.save(user);
主键注解:
FinalDB OneToMany懒加载使用方法:
public
class Parent{
private
int id;
@OneToMany(manyColumn=
"parentId")
private OneToManyLazyLoader<Parent,Child>children;
/*....*/
}
public
class Child{
private
int id;
private Stringtext;
@ManyToOne(column=
"parentId")
private Parentparent;
/*....*/
}
List<Parent>all
= db.findAll(Parent.class);
for(Parent
item :
all){
if(item.getChildren().getList().size()>0)
Toast.makeText(this,item.getText()+
item.getChildren().getList().get(0).getText(),Toast.LENGTH_LONG).show();
}
必须有一个主键。默认列名为id,并自增。使用注解@Id(column="id")
实际bean中没有id属性,使用@id(column="name") 使name成主键 ,非integer等整数类型,不会自增
属性注解
@Property(column=“uname") , 将属性name映射成表中的uname字段
取消orm的注解
@Transient 表示不将某属性映射到表中
一对多关系
@OneToMany(manyColumn="parentid")
多对一关系
@ManyToOne(column="parentid")
模型定义:
使用:
FinalDb对象,有很多方法,CRUD等操作。
