To use MyBatis Plus to retrieve a list of data, you can follow these steps:
1. Make sure you have MyBatis Plus configured in your project. If not, you can add the MyBatis Plus dependency to your project.
2. Create a mapper interface that extends the `BaseMapper` interface provided by MyBatis Plus. For example, suppose you have an entity called `User`, and you want to retrieve a list of users. You can create a `UserMapper` interface like this:
```java
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.yourpackage.User;
public interface UserMapper extends BaseMapper<User> {
}
```
3. Use the `selectList` method from the `BaseMapper` interface to retrieve the list of data. For example:
```java
@Autowired
private UserMapper userMapper;
public List<User> getUserList() {
return userMapper.selectList(null);
}
```
In this example, `null` passed to the `selectList` method means no specific conditions are applied, so it will retrieve all the users from the corresponding database table.
Remember to replace `com.yourpackage.User` with the actual package and class name for your entity.
This is a basic example of retrieving a list of data using MyBatis Plus. You can modify it according to your specific requirements.
