springmvc 處理Ajax 請求

 設置請求按鈕事件

<button id="jumpPage" onclick="jumpPage()" class="btn btn-primary btn-pill"  >跳轉</button>

請求處理，想服務器請求

function jumpPage() {
    var dbName = document.getElementById("selectDataBase").value;  //數據庫下拉框對象
    var tbName = document.getElementById("selectTable").value;
    $.ajax({
        url: "db/index",  //請求路徑
        type: "post",   
        data: {dbName:dbName,tbName:tbName},   //頁面參數
        success: function (data) {
            alert(data);   //顯示返回的數據
        }
    })


}

服務器接收ajax請求，並自動返回至頁面 

@Controller
@RequestMapping("/db")
public class DbConfigController {

    @Autowired
    @Qualifier("dbConfig")
    private DbConfigService dbConfigService;  //數據庫配置

    @RequestMapping("/index")
    public String index(HttpServletRequest request){
       
        return "index";
    }
