mybtis plus 3.2.0 SQL injector configuration

A. Create a class definition method

public class MyMethod extends AbstractMethod {
    @Override
    public MappedStatement injectMappedStatement(Class<?> mapperClass, Class<?> modelClass, TableInfo tableInfo) {
        //自定义sql
        String sql = "delete from "+tableInfo.getTableName();
        //mapper接口的方法名
        String method = "deleteAllData";
        SqlSource sqlSource = languageDriver.createSqlSource(configuration, sql, modelClass);
        return addDeleteMappedStatement(mapperClass,method,sqlSource);
    }
}

II. Custom SQL injector

@Component
public class MyInjector extends DefaultSqlInjector {
    @Override
    public List<AbstractMethod> getMethodList(Class<?> mapperClass) {
        List<AbstractMethod> methodList = super.getMethodList(mapperClass);
        methodList.add(new MyMethod());
        return methodList;
    }
}

III. Adding just defined method in your class Mapper

@Repository
public interface UserMapper extends BaseMapper<User> {
    int deleteAllData();
}

IV. Test

@Test
    public void testInject(){
        userMapper.deleteAllData();
    }

operation result:
