## diboot-core: 全新优化内核
|
|||
|
全新精简内核,主要实现:
|
|||
|
1. 多表关联的自动绑定, 实现单表CRUD和多表关联的无SQL化
|
|||
|
2. 提供其他常用开发场景的简单封装。
|
|||
|
|
|||
|
#### 单表CRUD无SQL
|
|||
|
> 基于Mybatis-Plus实现(Mybatis-Plus具备通用Mapper方案和灵活的查询构造器)
|
|||
|
#### 多表关联查询无SQL(适用于大多数场景,拆分成单表查询自动实现结果绑定)
|
|||
|
> 通过注解实现多数场景下的关联查询无SQL
|
|||
|
##### 1. 注解自动绑定元数据(枚举值)的显示值Label
|
|||
|
~~~java
|
|||
|
@BindMetadata(type="GENDER", field = "gender")
|
|||
|
private String genderLabel;
|
|||
|
~~~
|
|||
|
##### 2. 注解自动绑定其他表的字段
|
|||
|
~~~java
|
|||
|
// 支持关联条件+附加条件绑定字段
|
|||
|
@BindField(entity=Department.class, field="name", condition="department_id=id AND parent_id>=0")
|
|||
|
private String deptName;
|
|||
|
|
|||
|
// 支持通过中间表的级联关联绑定字段
|
|||
|
@BindField(entity = Organization.class, field="name", condition="this.department_id=department.id AND department.org_id=id")
|
|||
|
private String orgName;
|
|||
|
~~~
|
|||
|
##### 3. 注解自动绑定其他表实体Entity
|
|||
|
~~~java
|
|||
|
// 支持关联条件+附加条件绑定Entity
|
|||
|
@BindEntity(entity = Department.class, condition="department_id=id")
|
|||
|
private Department department;
|
|||
|
|
|||
|
// 通过中间表的级联关联绑定Entity(支持附加条件)
|
|||
|
@BindEntity(entity = Organization.class, condition = "this.department_id=department.id AND department.org_id=id AND department.deleted=0")
|
|||
|
private Organization organization;
|
|||
|
~~~
|
|||
|
##### 4. 注解自动绑定其他表实体集合List<Entity>
|
|||
|
~~~java
|
|||
|
// 支持关联条件+附加条件绑定多个Entity
|
|||
|
@BindEntityList(entity = Department.class, condition = "id=parent_id")
|
|||
|
private List<Department> children;
|
|||
|
|
|||
|
// 通过中间表的 多对多关联 绑定Entity(支持附加条件)
|
|||
|
@BindEntityList(entity = Role.class, condition="this.id=user_role.user_id AND user_role.role_id=id")
|
|||
|
private List<Role> roleList;
|
|||
|
