# 简介 | Intro

Hibernate 增强工具包 - 只做增强不做改变，更加精简持久层`CRUD`操作

# 优点 | Advantages

- **纯正血统**：完全继承原生 `Hibernate` 的所有特性
- **最少依赖**：仅仅依赖 `Hibernate`
- **自动生成代码**：简化操作，使其专注于业务
- **自定义操作**：提供大量API，使开发更加顺畅
- **简化操作**：只需专注于业务，数据库操作请交给 `Hibernate-Plus`
- **无缝分页**：基于`Hibernate`分页，无需具体实现
- **数据库友好**：基于`Hibernate`，支持目前大多数主流数据库
- **避免Sql注入**：内置对特殊字符转义，从根本上预防Sql注入攻击
- **无配置文件**：无需编写SQL配置文件(例如：`Mybatis`的XML)，从而简化操作
- **主从分离**：简单配置即可实现主从分离

###DAO层

/*Dao接口类*/
	public interface DemoDao extends IDao<Tdemo> {

}

/*Dao接口实现类*/
	public class DemoDaoImpl extends DaoImpl<Tdemo> implements DemoDao {

}

###Service层
	
	/*Service接口类*/
	public interface DemoService extends IService<Vdemo> {

}

/*Service接口实现类*/
	public class DemoServiceImpl extends ServiceImpl<Tdemo, Vdemo> implements DemoService {
	
	}

###实体类注解
	    @Entity
		@Table(name = "demo")
		@DynamicInsert(true)
		@DynamicUpdate(true)
		public class Tdemo extends AutoPrimaryKey {
	
			private String demo1;
			private String demo2;
			private String demo3;
		
			@Column(name = "demo1")
			public String getDemo1() {
				return demo1;
			}
		
			public void setDemo1(String demo1) {
				this.demo1 = demo1;
			}
		
			@Column(name = "demo2")
			public String getDemo2() {
				return demo2;
			}
		
			public void setDemo2(String demo2) {
				this.demo2 = demo2;
			}
		
			@Column(name = "demo3")
			public String getDemo3() {
				return demo3;
			}
		
			public void setDemo3(String demo3) {
				this.demo3 = demo3;
			}
		}

####注解支持

>完全支持 `JPA` 注解，原生 `Hibernate` 用法

####强调

>不是表中字段的属性需要添加`@Transient`注解

####示例项目

##Hibernate-Plus - 简单用法示例

全部针对单表操作，每个实体类都需要继承Convert来PO、TO之间的装换

示例代码：

List<Vdemo> lists = new ArrayList<Vdemo>();
		for (int i = 0; i <= 100; i++) {
			Vdemo vdemo = new Vdemo();
			vdemo.setDemo1(i + "");
			vdemo.setDemo2(i + "");
			vdemo.setDemo3(i + "");
			lists.add(vdemo);
		}
		// 批量插入
		boolean insertBatch = demoService.insertBatch(lists);
		System.out.println(insertBatch);
		// Condition 链式查询列表
		List<Vdemo> vdemoList = demoService.selectList(SelectWrapper.instance().le("id", 10));
		System.out.println(vdemoList);
		Map map = new HashMap<>();
		map.put("id", 99L);
		// 根据Condition 查询单条记录
		Vdemo vdemo = demoService.selectOne(SelectWrapper.instance().eq("id", 10));
		System.out.println(vdemo);
		List<Map<String, Object>> mapList = demoService.selectMaps(SelectWrapper.instance().ge("id", 80));
		System.out.println(mapList);
		// 根据属性查询单条记录
		Vdemo vdemo1 = demoService.get("1");
		if (vdemo1 != null) {
			vdemo1.setDemo1("999");
			vdemo1.setDemo2("999");
			vdemo1.setDemo3("999");
			// 修改或保存
			demoService.saveOrUpdate(vdemo1);
		}

Vdemo vdemo2 = demoService.get("1");
		if (vdemo2 != null) {
			vdemo2.setId(null);
			demoService.saveOrUpdate(vdemo2);
		}

int selectCount2 = demoService.selectCount(SelectWrapper.instance().ge("id", 80));
		System.out.println(selectCount2);
		Page page = new Page(1, 20);
		page.setOrderByField("id");
		page.setAsc(false);
		// 查询分页
		Page selectPage = demoService.selectPage(SelectWrapper.DEFAULT, page);
		System.out.println(selectPage);
		// Condition链式查询分页返回Map
		Page selectMapPage = demoService.selectMapPage(SelectWrapper.instance().ge("id", 50), page);
		System.out.println(selectMapPage);
		// Condition链式查询分页返回VO
		Page selectPage2 = demoService.selectPage(SelectWrapper.instance().ge("id", 50), page);
		System.out.println(selectPage2);
		// Condition链式 删除单条记录
		demoService.delete(DeleteWrapper.instance().eq("id", 1));
		List<Vdemo> vdemos = demoService.selectList(SelectWrapper.instance());
		Iterator<Vdemo> iterator = vdemos.iterator();
		while (iterator.hasNext()) {
			Vdemo vdemo3 = iterator.next();
			vdemo3.setDemo1(vdemo3.getDemo1() + "Caratacus Plus 1");
			vdemo3.setDemo2(vdemo3.getDemo2() + "Caratacus Plus 2");
			vdemo3.setDemo3(vdemo3.getDemo3() + "Caratacus Plus 3");
		}
		// 批量修改
		demoService.updateBatch(vdemos);
		// Condition链式 删除所有记录
		demoService.delete(DeleteWrapper.DEFAULT);
