mybatis resultMap 嵌套，将部分属性对应封装到Map中，复杂映射mapper

 

XML文件 

    
        
        
        
        
        
        
        
        	
        	
            
            
        
    
    
        
    

//查询方法
	
		SELECT
			tc.type ,tc.column_code ,tc.label ,tc.placeholder , tc.b_required , tc.value ,tcd.value  as dicValue ,tcd.name as dicName,tcd.name as dic
		FROM
			template_column tc
			LEFT JOIN template_column_dict tcd ON tc.id = tcd.template_column_id
			where tc.tamplate_id= #{templateId}
			order by tc.order_by ,tcd.order_by
	

部分Java实体类 

@Data
public class ColumnValuesVO {

	private String name;

	private String value;

	private Map haha;

}

 结果如图：

参考文档连接：https://www.cnblogs.com/hamhog/p/3959451.html  介绍的是map的嵌套，讲解的很清楚，谢谢作者
