我有一個形式，並且一個場其綁定到一個用戶類，形式及其本領域<form：checkbox>隱藏的值搞亂我的表單？
<tr>
<td>AcceptTerms:</td>
<td><form:checkbox path="acceptTerms"/><td>
</tr>
但是在提交表單中的錯誤的時刻出現
由所發送的請求客戶端在語法上不正確。
我用螢火檢查，並得到這個
Parameters application/x-www-form-urlencoded
_acceptTerms on
email ZX
password ZXZX
rol 2
username ZxZ
Fuente
username=ZxZ&password=ZXZX&email=ZX&rol=2&_acceptTerms=on
的_acceptTerms其隱藏價值的複選框，因爲我認爲它春天標籤<form:checkbox>的默認。
這對我產生3個問題： 請問這個字段（_acceptTerms）與我的表單提交混亂嗎？ 爲什麼_acceptTerms始終設置爲on？ 如果這個領域確實搞砸了我的表格，我該如何擺脫它，或者我應該如何處理它？添加到用戶模型？
在此先感謝
