我有一个合约实体，它与generatorState实体有一对一的Map
我保存一个合同，它工作，并保存合同和generatorState然而，当我在Postman中获得合同时，我有generatorState的详细信息，而我试图将其设置为LAZY
有没有人能告诉我如何让合同实体有/没有generatorState的细节
主要

@Override
    public void run(String... args) throws Exception {

        Contract c1 = new Contract (60,"TSTE");

//        GeneratorState gs = new GeneratorState(60,100);
//        c.setGeneratorState(gs);
//
//        contractRepository.save(c);
//        Contract c2 = contractRepository.findById(60).get();
//        System.out.println("coucou");
 
    }

    public int getGeneratorId() {
        return generatorId;

    public GeneratorState(int generatorId, double lastPrice) {
        this.generatorId = generatorId;
        this.lastPrice = lastPrice;
    }
}
