jquery的ajax success回調函數不執行

     弄了好長時間，執行ajax請求的接口一直返回404，請求壓根就沒有傳到後臺，調試了半天，原因找到了ajax請求裏面的參數一定得跟java後臺裏面的請求參數保持一致才行；

data.productName = productname;
					data.functionName = functionname;
					data.producter = producter;
					data.backstage = backstage;
					data.front = front;
					data.tester = tester;
					data.branch = branch;
					data.fabuSystem = fabusystem;
					data.schedule = ispaiqi;
					data.sqlValid = issql;

public Map<String,String> createNewFunction(
			@RequestParam("productName") String productName,
			@RequestParam("functionName") String functionName,
			@RequestParam("producter") String producter,
			@RequestParam("backstage") String backstage,
			@RequestParam("front") String front,
			@RequestParam("tester") String tester,
			@RequestParam("branch") String branch,
			@RequestParam("fabuSystem") String fabuSystem,
			@RequestParam("schedule") String schedule,
			@RequestParam("sqlValid") String sqlValid){

這兩部分的參數一定得保持一致，修改好後問題就可以解決；
