动作链配置如下：

var chain={
  "default": {
    "ps": [
      "cn.wizzer.app.web.commons.processor.LogTimeProcessor",
      "cn.wizzer.app.web.commons.processor.GlobalsSettingProcessor",
      "org.nutz.mvc.impl.processor.UpdateRequestAttributesProcessor",
      "org.nutz.mvc.impl.processor.EncodingProcessor",
      "org.nutz.mvc.impl.processor.ModuleProcessor",
      "cn.wizzer.app.web.commons.processor.NutShiroProcessor",
      "cn.wizzer.app.web.commons.processor.XssSqlFilterProcessor",
      "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": 'org.nutz.mvc.impl.processor.FailProcessor'
  }
};

public class NutShiroProcessor extends AbstractProcessor {

    protected NutShiroMethodInterceptor interceptor;

    @Inject
    protected WeixinUserService weixinUserService;

注入失败，要怎么处理
