方法模板-乘法定义-我在做什么错了？

Question

我是c ++的新手，我在类中的模板方法方面遇到问题。

---建议后的完整代码---

serializerService.h

// Copyright (c) 2019 All rights reserved.
//
#pragma once

#include <string>
#include "ThorSerialize/SerUtil.h"
#include "ThorSerialize/JsonThor.h"

class SerializerService {
public:

    template <class T>
    std::string serialize(T &entity){
        using ThorsAnvil::Serialize::jsonExport;
        using ThorsAnvil::Serialize::PrinterInterface;

        std::stringstream stream;
        stream << jsonExport(entity, PrinterInterface::OutputType::Stream);
        return stream.str();
    };
};

serializerService.cpp

//#include "serializerService.h"

和 mainEndpoint.cpp ，其中还包含serializerService.h

#include <user.h>
#include "serializerService.h"
#include "mainEndpoint.h"

void MainEndpoint::doMain(const Pistache::Rest::Request &request, Pistache::Http::ResponseWriter response) {

    User user("admin@admin.com");
    user.setUsername("admin");

    SerializerService serializer;

    std::string data = serializer.serialize(user);


    response.cookies()
            .add(Pistache::Http::Cookie("lang", "pl_PL"));
    response.headers()
            .add<Pistache::Http::Header::Server>("Sandbox server v0.1")
            .add<Pistache::Http::Header::ContentType>(MIME(Application, Json));
//    response.send(Pistache::Http::Code::Ok, "{}");
    response.send(Pistache::Http::Code::Ok, data);
}

当我在包含头文件的serializerService.cpp行中启用时，出现错误：
