Java 布尔表达式，doPost servlet返回的游戏太多
Java 布尔表达式，doPost servlet返回的游戏太多,java,html,json,servlets,boolean,Java,Html,Json,Servlets,Boolean,doPost正在返回游戏时间超过5分钟的游戏，即使我在HTML表单中输入了最大5分钟的参数。为什么？我不知道。我已经打印出了布尔表达式中使用的所有参数，以查看它们是否包含正确的值，并且它们似乎是这样做的。以下是该打印的示例： 信息：拥有：虚假minPlayers:3 chosenPlayers:1 maxPlayers:6 chosenPlaytime:5游戏时间：90信息：拥有：真实玩家：2 chosenPlayers:1名maxPlayers:-1名chosenPlaytime:5名游戏时间
doPost布尔表达式中使用的所有参数，以查看它们是否包含正确的值，并且它们似乎是这样做的。以下是该打印的示例：
信息：拥有：虚假minPlayers:3 chosenPlayers:1 maxPlayers:6
chosenPlaytime:5游戏时间：90信息：拥有：真实玩家：2
chosenPlayers:1名maxPlayers:-1名chosenPlaytime:5名游戏时间:-1名信息：
拥有：假minPlayers:2 chosenPlayers:1 maxPlayers:6
chosenPlaytime:5游戏时间：90信息：拥有：虚假玩家：1
chosenPlayers:1个maxPlayers:1个chosenPlaytime:5个游戏时间：50个信息：
拥有：假minPlayers:-1名chosenPlayers:1名maxPlayers:-1名
chosenPlaytime:5游戏时间：-1信息：拥有：真实玩家：2
游戏时间：5游戏时间：30
