# MybatisPlus-Generator Demo
22+
## Introduction
23+
24+
This demo shows how to use IoTDB-MybatisPlus-Generator
25+
26+
### Version usage
27+
28+
IoTDB: 2.0.1-beta
29+
mybatisPlus: 3.5.10
30+
31+
### 1. Install IoTDB
32+
33+
please refer to [https://iotdb.apache.org/#/Download](https://iotdb.apache.org/#/Download)
34+
35+
### 2. Startup IoTDB
36+
37+
please refer to [Quick Start](http://iotdb.apache.org/UserGuide/Master/Get%20Started/QuickStart.html)
38+
39+
Then we need to create a database 'test' by cli in table model
40+
```
41+
create database test;
42+
use test;
43+
```
44+
Then we need to create a database 'table'
45+
```sql
46+
CREATE TABLE mix (
47+
time TIMESTAMP TIME,
48+
region STRING TAG,
49+
plant_id STRING TAG,
50+
device_id STRING TAG,
51+
model_id STRING ATTRIBUTE,
52+
maintenance STRING ATTRIBUTE,
53+
temperature FLOAT FIELD,
54+
humidity FLOAT FIELD,
55+
status Boolean FIELD,
56+
arrival_time TIMESTAMP FIELD
57+
) WITH (TTL=31536000000);
58+
```
59+
60+
### 3. Build Dependencies with Maven in your Project
61+

### 4. Start the Main.java
133+
134+
### 5. the target file location
135+
136+
You can see the target file in your Project
137+
```
138+
org/apache/iotdb/controller/MixController.java
139+
org/apache/iotdb/entity/Mix.java
140+
org/apache/iotdb/mapper/MixMapper.xml
141+
org/apache/iotdb/service/MixService.java
142+
org/apache/iotdb/service/MixServiceImpl.java
143+
org/apache/iotdb/MixMapper.xml
144+
145+
```
146+
147+
### 6. add & alter Annotations
148+
149+
The generated code files `entity/Table1.java` and `entity/Table2.java` need to be manually adjusted to support multi-primary key queries.
150+
151+
```java
152+
// add import
153+
import com.github.jeffreyning.mybatisplus.anno.MppMultiId;
154+
155+
// add @MppMultiId
156+
@MppMultiId
157+
// alter @TableId() -->> @TableField()
158+
@TableField("time")
159+
private Date time;
160+
161+
// add @MppMultiId
162+
@MppMultiId
163+
// alter @TableId() -->> @TableField()
164+
@TableField("region")
165+
private String region;
166+
167+
// add @MppMultiId
168+
@MppMultiId
169+
// alter @TableId() -->> @TableField()
170+
@TableField("plant_id")
171+
private String plantId;
172+
173+
// add @MppMultiId
174+
@MppMultiId
175+
// alter @TableId() -->> @TableField()
176+
@TableField("device_id")
177+
private String deviceId;
178+
//
179+
180+
```
