.mb {margin-bottom: .5rem; }Controller層配置路由
涉及到兩個(gè)頁(yè)面，不允許直接訪問(wèn)，所以需要在Controller層配置路由轉(zhuǎn)發(fā)
com.artisan.o2o.web.shopadmin.ShopAdminController.java
@RequestMapping(value = "/shoplist", method = RequestMethod.GET)public String shopList() {return "shop/shoplist";}@RequestMapping(value = "/shopmanagement", method = RequestMethod.GET)public String shopManagement() {return "shop/shopmanagement";}單元測(cè)試
驗(yàn)證獲取店鋪列表
com.artisan.o2o.web.shopadmin.ShopController#getShopList方法加入斷點(diǎn)
tomcat以debug的模式啟動(dòng)，啟動(dòng)后 訪問(wèn) http://localhost:8080/o2o/shopadmin/shoplist
逐步調(diào)測(cè)
檢查結(jié)果是否符合預(yù)期，如果都沒(méi)問(wèn)題的話，就可以得到如下前端頁(yè)面
驗(yàn)證商鋪管理頁(yè)面
首先我們先回顧下控制層的邏輯
當(dāng)瀏覽器的請(qǐng)求 如下
http://localhost:8080/o2o/shopadmin/shopmanagement?shopId=5即shopId合法
Shop shop = new Shop(); shop.setShopId(shopId); // 將currentShop放到session中 request.getSession().setAttribute("currentShop", shop); modelMap.put("redirect", false);此時(shí)將shop放在session中，key為currentShop，并且告訴View層 無(wú)需跳轉(zhuǎn)，停留在該頁(yè)面。
如果訪問(wèn)的是http://localhost:8080/o2o/shopadmin/shopmanagement 沒(méi)有傳遞shopId，想直接訪問(wèn) 商鋪管理頁(yè)面 ， 我們首先獲取shopId,
工具類 ：
此時(shí)，shopId = -1 , 走如下邏輯
if (shopId < 0) {// 嘗試從當(dāng)前session中獲取Shop currentShop = (Shop) request.getSession().getAttribute("currentShop");if (currentShop == null) {// 如果當(dāng)前session中也沒(méi)有shop信息,告訴view層 重定向modelMap.put("redirect", true);modelMap.put("url", "/o2o/shopadmin/shoplist");}else{// 告訴view層 進(jìn)入該頁(yè)面modelMap.put("redirect", false);modelMap.put("shopId", currentShop.getShopId());}}首先嘗試從session中通過(guò)key來(lái)獲取該shop信息，取到的話，告訴前端View層，無(wú)需跳轉(zhuǎn)，并將shopId傳遞給View層，方便給 shopInfo 這個(gè)按鈕設(shè)置超鏈接，傳入shopId,點(diǎn)擊即為編輯商鋪。
如果session中還是沒(méi)有shop的信息，告訴view層跳轉(zhuǎn)到商鋪列表
if(data.redirect){window.location.href = data.url;}所以測(cè)試的時(shí)候，為了安全起見(jiàn)，請(qǐng)將瀏覽器的緩存清空。
首先訪問(wèn)
http://localhost:8080/o2o/shopadmin/shopmanagement ,因?yàn)榈谝淮卧L問(wèn)，沒(méi)有傳入shopId ,session中也沒(méi)有數(shù)據(jù)，會(huì)跳轉(zhuǎn)到 http://localhost:8080/o2o/shopadmin/shoplist 商鋪列表頁(yè)面
然后在訪問(wèn)一個(gè) http://localhost:8080/o2o/shopadmin/shopmanagement?shopId=5 ,進(jìn)入到shopId=5的店鋪管理頁(yè)面。
最后在http://localhost:8080/o2o/shopadmin/shopmanagement ，因?yàn)?第二次訪問(wèn)了shopId=5的店鋪，session中存入了數(shù)據(jù)，所以也進(jìn)入到shopId=5的店鋪管理頁(yè)面。
這部分僅僅是session的操作，是否有權(quán)限進(jìn)入改頁(yè)面后續(xù)會(huì)通過(guò)攔截器來(lái)實(shí)現(xiàn)。
我們還預(yù)留了幾個(gè)按鈕，接著繼續(xù)實(shí)現(xiàn)吧
