mybatis遍历集合List和数组Array

一、遍历集合

1.不用注解

public void insertList(List users);

insert into user (id,name,password,sex,age)
values 

    (#{item.id,jdbcType=INTEGER}, #{item.name,jdbcType=VARCHAR}, 
    #{item.password,jdbcType=VARCHAR}, #{item.sex,jdbcType=TINYINT}, 
    #{item.age,jdbcType=INTEGER})

2.使用@Param注解

public void insertList(@Param("list") List users);

insert into user (id,name,password,sex,age)
values 

    (#{item.id,jdbcType=INTEGER}, #{item.name,jdbcType=VARCHAR}, 
    #{item.password,jdbcType=VARCHAR}, #{item.sex,jdbcType=TINYINT}, 
    #{item.age,jdbcType=INTEGER})

二、遍历数组Array

1.不用注解

public List selectAllUsers(Integer[] ids);

select * from user where id in

       #{item,jdbcType=INTEGER}

 
  
2.使用@Param注解
 
  
public List selectAllUsers(@Param("ids") Integer[] ids);
 
  

select * from user where id in

       #{item,jdbcType=INTEGER}

三、遍历两个集合

List selectSubOrgDetail(@Param("params") Map;

SELECT org.org_id,org.org_name,t.goods_id,t.num,`user`.user_pic 
FROM 
organization org 
INNER JOIN 
    (SELECT belong_org,num,goods_id 
    FROM
    org_goods
    WHERE
    now_org = 1 AND
    belong_org in
    
        #{id}
    
    AND goods_id in         
    
        #{id}
    ) t
ON
org.org_id=t.belong_org
INNER JOIN
`user`
ON
`user`.org_id=t.belong_org
