我正在尝试从MySQL数据库获取数据，PDO但不幸的是PDO将结果作为字符串数组返回。我想将本地MySQL数据类型保留在结果数组中。
我尝试设置PDO::ATTR_DEFAULT_FETCH_MODE为PDO::FETCH_ASSOCAND，PDO::FETCH_OBJ但是它仍以INT字符串形式返回数据。
这是转储的结果：
array (size=1)
0 =>
object(stdClass)[27]
public 'id' => string '3' (length=1)
public 'avatar' => string '' (length=0)
public 'fullName' => string 'Mikheil Janiashvili' (length=19)
public 'email' => string 'xxxxx@yyyyy.com' (length=17)
public 'phone' => string '23 3537 20 03544' (length=12)
public 'educationGE' => string '' (length=0)
public 'educationEN' => string '' (length=0)
public 'educationRU' => string '' (length=0)
public 'experienceGE' => string '' (length=0)
public 'experienceEN' …我有一个这样的集合:
[[patient1,value1], [patient2,value2]]
例如.
x = [[1, 20.28], [1, 11.11], [2, 4.60], [2, 3.68]]
我用它countBy来得到每位患者的计数:
def counts = x.countBy{patient, value -> patient}
我试图得到每个病人的总和没有运气:
def sums = x.groupBy({patient, value -> patient }).collectEntries{p, v -> p:v.sum()}
有什么我想念的吗？
注意:这里的总体目标是获得患者使用的平均值:
def avgs = sums.collect{patient, value -> (value / counts[patient]) }
谢谢!
我正在运行SpringBoot Application刚检查的服务器日志,并得到了这样的几个错误.由于每天12/24小时后出现错误,我无法理解是什么原因造成的.
运行Tomcat版本 8.5.11
