Question

我正在使用ExtJS4，Spring JPA，Restful服务和Hibernate技术开发书籍存储库应用程序。我需要在Extjs中创建一个gridpanel，在加载页面时列出所有书籍，并且网格下面应该有一个表格，可以添加书籍。一旦用户点击表单上的“添加”按钮，网格就会自动刷新并显示新书。

从头开始构建所有东西对我来说是一种挑战。我已经构建了服务器端代码并获得了listBooks和saveBook方法的响应。现在我需要构建一个ExtJS页面来调用我在Spring中定义的服务来显示书籍列表并添加一本书。我正在努力将ExtJS与服务器端集成在一起。我无法通过extjs调用服务。我将衷心感谢您的帮助！我附上一些截图。我也为他们各自的Impl类创建了Dao和Service类。

＆＃13; [BookController的[BookDaoImpl [BookServiceImpl [其余 - web.xml[ProjectStructure] 1 servlet.xml中

Answer 1

您的代码存在一些问题。

由于您希望在List之后使用表单，因此您应该创建Panel而不是Window。
您正在将表单窗口呈现给正文但不是列表

这是更新的代码。
