## 添加依赖
8+
## Add Dependency
9+
10+
### Maven
11+
#### 1. 在 pom.xml 中添加 JitPack 仓库
12+
#### 1. Add the JitPack repository to pom.xml
13+
```xml
14+
<repositories>
15+
<repository>
16+
<id>jitpack.io</id>
17+
<url>https://jitpack.io</url>
18+

23+
24+
<br />
25+
26+
#### 2. 在 pom.xml 中添加 apijson-mongodb 依赖
27+
#### 2. Add the apijson-mongodb dependency to pom.xml
28+
```xml
29+
<dependency>
30+
<groupId>com.github.APIJSON</groupId>
31+
<artifactId>apijson-mongodb</artifactId>
32+
<version>LATEST</version>
33+
</dependency>
34+
```
35+
36+
<br />
37+
38+
https://github.com/APIJSON/APIJSON-Demo/blob/master/APIJSON-Java-Server/APIJSONBoot/pom.xml
39+
40+
<br />
41+
<br />
42+
43+
### Gradle
44+
#### 1. 在项目根目录 build.gradle 中最后添加 JitPack 仓库
45+
#### 1. Add the JitPack repository in your root build.gradle at the end of repositories
46+
```gradle
47+
allprojects {
48+
repositories {
49+
maven { url 'https://jitpack.io' }
50+
}
51+
}
52+
```
53+
<br />
54+
55+
#### 2. 在项目某个 module 目录(例如 `app`) build.gradle 中添加 apijson-mongodb 依赖
56+
#### 2. Add the apijson-mongodb dependency in one of your modules(such as `app`)
57+
```gradle
58+
dependencies {
59+
implementation 'com.github.APIJSON:apijson-mongodb:latest'
60+
}
61+
```
62+
63+
<br />
64+
<br />
65+
<br />
66+
67+
## 使用
68+
## Usage
69+
70+
在你项目继承 AbstractSQLExecutor 的子类重写方法 getValue <br/>
71+
Override getValue in your SQLExecutor extends AbstractSQLExecutor
72+
```java
73+
@Override
74+
protected Object getValue(SQLConfig<Long> config, ResultSet rs, ResultSetMetaData rsmd, int tablePosition, JSONObject table, int columnIndex, String lable, Map<String, JSONObject> childMap) throws Exception {
75+
Object v = super.getValue(config, rs, rsmd, tablePosition, table, columnIndex, lable, childMap);
76+
return MongoUtil.getValue(v);
77+
}
78+
```
79+
80+
#### 见 [MongoUtil](/src/main/java/apijson/mongodb/MongoUtil.java) 的注释及 [APIJSONBoot](https://github.com/APIJSON/APIJSON-Demo/blob/master/APIJSON-Java-Server/APIJSONBoot) 的 [DemoSQLExecutor](https://github.com/APIJSON/APIJSON-Demo/blob/master/APIJSON-Java-Server/APIJSONBoot/src/main/java/apijson/demo/DemoSQLExecutor.java) <br />
81+
82+
#### See document in [MongoUtil](/src/main/java/apijson/mongodb/MongoUtil.java) and [DemoSQLExecutor](https://github.com/APIJSON/APIJSON-Demo/blob/master/APIJSON-Java-Server/APIJSONBoot/src/main/java/apijson/demo/DemoSQLExecutor.java) in [APIJSONBoot](https://github.com/APIJSON/APIJSON-Demo/blob/master/APIJSON-Java-Server/APIJSONBoot)
