## README

## 介绍

让mybatisplus支持动态生成mapper接口（当前项目基于jdk21，点击[传送门](https://gitee.com/easy-framework/easy-apt-support)访问基于jdk8的版本）

## maven引用[点击查看最新版本](https://central.sonatype.com/artifact/com.xiaoyudeguang/mybatis-plus-apt-support)

<dependency>

```
如果想要自定义Mapper接口的内容，可以在pom文件中加入下面的代码：

```
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>21</source>
                <target>21</target>
                <release>21</release>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.18.30</version>
                    </path>
                    <path>
                        <groupId>com.xiaoyudeguang</groupId>
                        <artifactId>mybatis-plus-apt-support</artifactId>
                        <version>${最新版本号}</version>
                    </path>
                </annotationProcessorPaths>
                <compilerArgs>
                    <arg>-Amapper.package=com.example.mapper【需要改成自己的包名】</arg>
                    <arg>-Amapper.naming=%sDynamicMapper</arg>
                    <arg>-Ainterface.superClass=com.baomidou.mybatisplus.core.mapper.BaseMapper</arg>
                    <arg>-Ainterface.annotations=org.apache.ibatis.annotations.Mapper</arg>
                    <arg>-Averbose=true</arg>
                </compilerArgs>
            </configuration>
        </plugin>
    </plugins>
</build>
```

## 使用说明

### 新增一个实体类（一定要添加@TableName注解）

```
@TableName("sys_app")
public class SysApp {

    private String appNo;

    private String appName;
}
```

在idea里执行“maven compile”名称后就可以“{项目路径}/target/classes/{上面配置的包名}”下面就可以看到生成的mapper文件啦

### 验证

```
@Service
public class SysAppServiceImplimplements CommandLineRunner {

    @Autowired
    private SysAppDynamicMapper sysAppDynamicMapper;

    @Override
    public void run(String... args) throws Exception {
        JsonLambdaQueryWrapper<SysApp> sysAppDynamicMapperJsonWrapper = new JsonLambdaQueryWrapper<>();
        sysAppDynamicMapper.selectList(Wrappers.lambdaQuery());
    }
}
```
