NUTZ中處理系統未捕獲異常

關鍵內容

---

• mvc-chain.js
• ViewProcessor
• ai.setFailView(“redirect:/sysError.html”);
• log.error(this.trrowableToString(ac.getError()));

---

首先，在mvc-chain.js中配置系統異常處理類

var chain={
    "default" : {
        "ps" : [
              "com.carforu.processor.SystemLogProcessor",
"org.nutz.mvc.impl.processor.UpdateRequestAttributesProcessor",         "org.nutz.mvc.impl.processor.EncodingProcessor",         "org.nutz.mvc.impl.processor.ModuleProcessor",          "org.nutz.integration.shiro.NutShiroProcessor",
"org.nutz.mvc.impl.processor.ActionFiltersProcessor",
"org.nutz.mvc.impl.processor.AdaptorProcessor",
"org.nutz.mvc.impl.processor.MethodInvokeProcessor",
              "org.nutz.mvc.impl.processor.ViewProcessor"
              ],
        "error" : 'com.carforu.data.SysUncaughtException'
    }
};

---

然後自己寫一個實例繼承ViewProcessor

---

最後在它的方法中設置自己的錯誤提示頁面

 public void init(NutConfig config, ActionInfo ai) throws Throwable {
     ai.setFailView("redirect:/sysError.html");
    view = evalView(config, ai, ai.getFailView());

 }
