当我向域 Class 添加更多字符串变量时，Grails 项目无法编译
Grails Project not compiling when I add more String variable to Domain Class
我正在尝试向我的对象影片中添加更多字符串变量。
class Film {
String nom, note, date //this work!!
String description //Doesn't work :(
static constraints={
/*
nom unique:true
nom blank:false
*/
}
}
我收到了一条厄运消息供解释：
java.lang.NullPointerException: null

我试图删除我的其他代码的 must，但我没有发现任何区别。
看起来 description 是基础数据库中的保留关键字。尝试将其重命名为 myDescription
我实际上找到了解决方案，也许是原因。问题出在我编译或执行时生成的填充文件中。在 netbeans 中，您可能 "reload the project"。它确实有效。
感谢您尝试回答。
我正在尝试向我的对象影片中添加更多字符串变量。
class Film {
String nom, note, date //this work!!
String description //Doesn't work :(
static constraints={
/*
nom unique:true
nom blank:false
*/
}
}
我收到了一条厄运消息供解释：
