Grails 自定义服务器页面（自定义 gsp）

我有一个控制器和一个 gsp。我继续尝试构建该项目，但在我的 gsp 上收到问题。

它告诉我“当前作用域已经包含一个名为 it 的变量”

<html>
  <head>
    <title>Book Collector</title>
    <meta name="layout" content="main" />
  </head>
  <body>
    <h1>Book Editor</h1>
    <table>
      <tr>
        <th>Book Name</th>
        <th>Author</th>
        <th>Page Number</th>
        <th>Vendor</th>
        <th>Date Scanned</th>
        <th>Date Read</th>
      </tr>
      <% bookList.each { it -> %>
      <tr>
        <td><%= it.bookName %></td>    //this is where the error starts
        <td><%= it.author %></td>      //error (it)
        <td><%= it.pageNumber %></td>  //error (it)
        <td><%= it.lastScan %></td>    //error (it)
        <td><%= it.lastRead %></td>    //error (it)
        <% } %>
      </tr>
    </table>
  </body>
</html>

我不允许这样使用“it”吗？或者我遗漏了一些明显的东西？

I have a controller and a gsp. I go ahead and attempt to build the project but receive issues on my gsp.

It is telling me "The current scope already contains a variable of the name it"

<html>
  <head>
    <title>Book Collector</title>
    <meta name="layout" content="main" />
  </head>
  <body>
    <h1>Book Editor</h1>
    <table>
      <tr>
        <th>Book Name</th>
        <th>Author</th>
        <th>Page Number</th>
        <th>Vendor</th>
        <th>Date Scanned</th>
        <th>Date Read</th>
      </tr>
      <% bookList.each { it -> %>
      <tr>
        <td><%= it.bookName %></td>    //this is where the error starts
        <td><%= it.author %></td>      //error (it)
        <td><%= it.pageNumber %></td>  //error (it)
        <td><%= it.lastScan %></td>    //error (it)
        <td><%= it.lastRead %></td>    //error (it)
        <% } %>
      </tr>
    </table>
  </body>
</html>

Am I not allowed to use 'it' like that? Or is there something obvious that I'm missing?
