# imitation-sql

#### 介绍
java代码中像写编写SQL语句一样，编写代码

#### 软件架构
软件架构说明

#### 使用说明

##### 1.基本用法

```java
//1.select
SqlBuilder<UserEntity> sqlBuilder = new SqlBuilder<>(UserEntity.class);
String sql = sqlBuilder.select().buildSql();

//2.select where
SqlBuilder<UserEntity> sqlBuilder = new SqlBuilder<>(UserEntity.class);
String sql = sqlBuilder.select().where(o -> o.and(UserEntity::getUserName, "11").and(UserEntity::getPassword, "1234")).buildSql();

//3.select Where group by order by
SqlBuilder<UserEntity> sqlBuilder = new SqlBuilder<>(UserEntity.class);
String sql = sqlBuilder.select().where(o -> o.and(UserEntity::getUserName, "11").and(UserEntity::getPassword, "1234")).groupBy(o -> o.groupBy(UserEntity::getUserName)).orderBy(o -> o.asc(UserEntity::getUserName)).buildSql();

//4.select  join where
SqlBuilder<UserEntity> sqlBuilder = new SqlBuilder<>(UserEntity.class);
String sql = sqlBuilder.select().leftJoin(o -> o.eq(UserRoleEntity.class, UserEntity::getId, UserRoleEntity::getUserId))
        .innerJoin(o -> o.eq(UserRoleEntity.class, RoleEntity.class, UserRoleEntity::getRoleId, RoleEntity::getId))
        .where(o -> o.and(UserEntity::getUserName, "11").and(UserRoleEntity.class, UserRoleEntity::getRoleId, "1")).buildSql();
        
```

##### 2.自动生成的api接口

```java
使用方法
在实体类上，继承BaseEntity，添加@EnableAutoApi注解即可

示例
@Setter
@Getter
@TableName("t_user")
@EnableAutoApi
public class UserEntity extends BaseEntity {

private String userName;

private String password;
}
```

自动生成的接口

#{entityName} 代表具体的实体类名称

| 接口名称     | 接口地址                           | 接口方法 | Content-Type     |
| ------------ | ---------------------------------- | -------- | ---------------- |
| 详情         | /#{entityName} /detail/{id}        | GET      |                  |
| 分页查询     | /#{entityName}/page                | POST     | application/json |
| 列表查询     | /#{entityName}/list                | POST     | application/json |
| 新增         | /#{entityName}                     | POST     | application/json |
| 修改         | /#{entityName}                     | POST     | application/json |
| 删除         | /#{entityName}                     | DELETE   |                  |
| 批量删除     | /#{entityName}/batchDelete         | DELETE   |                  |
| 物理删除     | /#{entityName}/physicalDelete      | DELETE   |                  |
| 批量物理删除 | /#{entityName}/physicalBatchDelete | DELETE   |                  |

{
  "code": "0", //返回码 0-成功；-1失败
