public class Book extends SugarRecord {
String title;
String edition;
public Book(){
}
public Book(String title, String edition){
this.title = title;
this.edition = edition;
}
}
或者:
@Table
public class Book {
private Long id;
public Book(){
}
public Book(String title, String edition){
this.title = title;
this.edition = edition;
}
public Long getId() {
return id;
}
}
步骤4:基本使用方法
保存Entity:
Book book = new Book("Title here", "2nd edition")
book.save();
加载 Entity:
Book book = Book.findById(Book.class, 1);
更新 Entity:
Book book = Book.findById(Book.class, 1);
book.title = "updated title here"; // modify the values
book.edition = "3rd edition";
book.save(); // updates the previous entry with new values.
删除 Entity:
Book book = Book.findById(Book.class, 1);
book.delete();
批量操作:
List<Book> books = Book.listAll(Book.class);
Book.deleteAll(Book.class);
