Spring Framework JSP表單發佈

我正在嘗試使用GlassFish Server 4.1.1在NetBeans 8.1中使用Maven和Spring Framework創建我的第一個JSP表單發佈。Spring Framework JSP表單發佈

當我運行應用程序，我的主頁打開罰款這是我的index.jsp和URL是localhost：8080/mavenproject1。

當我點擊表單上的提交按鈕時，我的URL是localhost：8080/selectSearch，404找不到錯誤。以下是我認爲會參與這項工作和項目結構的文件。

的pom.xml

發生了什麼事是不能找到x.jsp。如果你要註釋方法

public String x(ModelMap map)

這樣

public @ResponseBody String x(ModelMap map)

然後，它會簡單地返回「X」，但目前的情況是，它試圖找到x.jsp不存在。

或者，你可以改變它返回selectSearch，而不是因爲你具有對應名稱的視圖，就像這樣：

@RequestMapping(value = "/searchSelect", method = RequestMethod.POST) 
public String x(ModelMap map) { 
    return "searchSelect"; 
}

我曾與一些變化並沒有什麼發揮各地似乎解決這個問題。我注意到的是，如果我從DefaultController中刪除任何映射到selectSearch並將表單上的動作設置爲selectSearch或x，則錯誤是相同的。這看起來像我的代碼只是跳過默認的控制器。我是Java的新手，所以我不確定是否需要每個jsp的控制器。 – dutchlab

我找到了searchSelect jsp，但現在它顯示的是x的返回值，而不是searchSelect.jsp中的html – dutchlab

@dutchlab然後它實際上並沒有找到「searchSelect jsp」，它只是調用Controller中的處理程序方法。你需要從你的方法中返回字符串「searchSelect」，並且_do not_使用「@ ResponseBody」註釋 –
