Mybatis什么时候用resultMap,什么时候用resultType
今早上在用Mybatis的时候遇到了多表查询,一直用的resultType,以前的话都是把返回的实体bean里面添加两个表所有的字段,当然这样写的弊端很大的,很多没用的字段也查询出来了,然后早上百度了一下myBatis的多表查询,发现了有个resultType可以来解决(以前上学的时候学过,但是一直不理解,哈哈),废话不多说直接上代码
这是我的sql查询语句
以往都用的resultType,然后返回值类型直接写实体bean,这次改成了resultMap,既然引入resultMap,就需要写个resultMap咯,下面是我写的ResultMap
这个resultMap需要解释几个地方,懒得在代码上写备注了,就这么随便讲讲吧,这里面有几个地方需要注意,这里面的type就是你要回查询的第一表的实体bean,id就是sql语句面的那个resultMap对应的名字,column就是数据库中的表的名字,property这个就是你实体中的字段名字,collection 对应的另外一张表,可以有多个,两张表用一个这个,三张表就用两个,以此类推,oftype指定的是映射到list集合属性中实体的类型,然后直接运行,然后报错,如下

好吧,我的失误,实体bean里面少个字段,然后添加这个字段,然后继续运行

哈哈,有报错了,这次提示,找不到trail这个集合,也就是在关联表的时候,没找到要关联的表,嗯,来看下我的实体bean
@Data
public class Device {
public Integer id;
public String iot;
public String online;
public String name;
public String phone;
public String pic;
public String adress;
public String opinion;
public Date creattime;
public Integer groupid;
public Integer userid;
public Integer hidden;
public Double lon;
public Double lat;
public String power;
public int dwfs;
}
哦哦,果然没有那个List集合的trail,好的那我们加上去看看结果
@Data
public class Device {
public Integer id;
public String iot;
public String online;
public String name;
public String phone;
public String pic;

public Integer userid;
public Integer hidden;
public Double lon;
public Double lat;
public String power;
public int dwfs;
private List trail;
}
嗯,现在加上去了,这里有人问志伟,你咋不谢get,set啊,嗯,lombok了解一下,这里就不多说那个了,然后我们运行下我们的代码

嗯,得到了我想要的数据了,最新的一条设备和轨迹信息,就写到这里吧,呼呼
