NUTZ中处理系统未捕获异常

关键内容

---

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

---

首先，在mvc-chain.js中配置系统异常处理类

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'
    }
};

---

然后自己写一个实例继承ViewProcessor

---

最后在它的方法中设置自己的错误提示页面

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

 }
