angular4中添加service的DI注入后，编译后在tomcat下运行，一直提示

首先少了

var __Metadata = (this && this.__Metadata) || function (k,v) {
    if (typeof Reflect === "object" && typeof Reflect.Metadata === "function") return Reflect.Metadata(k,v);
};

__Metadata("design:paramtypes",[TestService_1.TestService])

看来编译方式还得再调整

在grunt-ts可以增加编译项：

emitDecoratorMetadata:true danielinbiti
