EasyDB

闲时无聊拿来学习java的。

实体类 public class Dog extends EntityBase {

@Id(type=Type.String)   // -- 自定义ID，默认不需要声明id，则为自增int类型
private String id;
private String name;
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;
}
private int age;

}

数据操作

public static void main(String[] args) {

	//web系统在web.xml中配置服务器启动时加载该监听类
	
	//当前为测试，手动加载此监听类
	
	ContextLoaderListener listener=new ContextLoaderListener();
	
	Dog dog=new Dog();
	
	dog.setAge(3);
	
	dog.setId("testid");
	
	dog.setName("jeep");
	
	dog.save();//增
	
	dog.setId("testid");
	
	dog=dog.load();//根据id查询
	
	dog.setName("jeep2");
	
	dog.update();//修改name
	
	List<Dog> results=dog.findListBySQL("name = ?", "jepp2");//条件查询
	
	if(results.size()>0){
	
		dog=results.get(0);
		
	}
	
	dog.print();//打印属性值
	
	dog.delete();//删除
}
