MyBatis简单批量删除小示例forOracle

建立一个Vo类

public class Vo {

	private List<Integer> ids;

    public List<Integer> getIds()
    {
        return ids;
    }

    public void setIds(List<Integer> ids)
    {
        this.ids = ids;
    }
}

原因是Swagger拼入的字符串不一定是数组 所以借助一个Vo类

Controller

@PostMapping("deletevideos")
	@ApiOperation(value = "删除摄像头")
	public boolean deleteCarByIds(@RequestBody Vo voids){
		return videoService.deletevideos(voids);
	}

Service

	public boolean deletevideos(Vo voids) {
		// TODO Auto-generated method stub
		
		try {
			List<Integer> ids = voids.getIds();
			
			videoMapper.deletevideos(ids);
			return true;
		
		} catch (Exception e) {
			log.error("deletevideos————批量删除摄像头异常: ");
			log.error(e.getMessage());
		}
		return false;
	}

Dao

void deletevideos(List<Integer> voids);

Mapper

<delete id="deletevideos" parameterType="java.lang.Integer">
	DELETE FROM T_DEVICE_VIDEO 
	 WHERE ID 
            IN
        <foreach item="item" collection="list" open="(" separator="," close=")">
            #{item,jdbcType=INTEGER}
        </foreach>
</delete>

或者可以 让开始参数传入一个字符串 我们自己来分割成 数组。

String[] arrids = ids.split(",");
List<String> list=Arrays.asList(arrids);
