我正在尝试将项目从传统（工作）Java servlet 应用程序迁移到 NetBeans IDE 中的 Spring MVC，但我的程序绝对拒绝 ping 控制器。在客户端，我看到以下 404 错误：
index.do?displayType=table:1 加载资源失败：服务器响应状态为 404（未找到）
index.do?displayType=table:1 加载资源失败：服务器响应状态为 404（未找到）
我像这样调用控制器方法：
$.get("index.do","displayType=table", function( data ) {
jstring = JSON.parse(data.substr(12).slice(0, -1));
});
$.get("index.do","displayType=pivot",function(unparsedJSON) {});
$.post("index.do","jsonString=" + JSON.stringify(hot.getData()));
以下是我的控制器和 xml 配置文件：
映射控制.java
package controllers;
import infoLoader.JsonWriter;
import infoLoader.getJSON;
import java.util.logging.Level;
import java.util.logging.Logger;
import static org.springframework.http.HttpMethod.GET;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
@RequestMapping("/")
public class MappingControl {
@RequestMapping(value="/index.do", method=RequestMethod.GET)
public String populatePivotAndSheet(@RequestParam("displayType") String type) {
String returnedJSON = "";
try {
returnedJSON = getJSON.getJSON(type);
} catch (Exception ex) {
System.out.println("Unable to retrieve JSON");
}
return returnedJSON;
}
@RequestMapping(value="/index.do", method=RequestMethod.POST)
public void deliverSheet(@RequestParam("jsonString") String writableJSON) {
String returnedJSON = "";
JsonWriter.writeJSON(writableJSON);
}
}

define an explicit mapping for it.

我一直在基于 NetBeans 提供的默认 Spring-MVC 模板构建它，所以如果你们中的任何人认为该模板格式不正确并且应该以某种方式进行更改，我将不胜感激您的任何意见。
非常感谢您的时间，伙计们，如果有任何不清楚的地方，请告诉我。
