Question

有没有办法用通配符自动包装所有搜索？

e.g：

 Book.search("*${params.q}*", params)

Answer 1

我不熟悉.search（你使用插件吗？）。但是，对于模型中的通配符搜索，我通常在域模型类中创建一个方法。在您的示例中，

在Book模型类中：

class Book {
   String title
   String author
   int year

   static List wildSearch(par, val) {
      def foundList = this.executeQuery("select b FROM Book b WHERE ${par} like \'%${val}%\'")
      return foundList
   }
}

在您的控制器中：

def searchBook = {
   def b1 = new Book(title: "Farewell To Arms", author: "Ernest Hemingway").save()
   def b2 = new Book(title: "The Brother's Karamazov", author: "Anton Chekov").save()
   def b3 = new Book(title: "Brothers in Arms", author: "Cherry Dalton").save()

   // If you search for "Arms", This returns b1 and b3 
   def found = Book.wildSearch("title", params.title)
}
