后端的接口调用如下：

package com.aynu.handler;

import com.aynu.beans.People;
import com.aynu.service.ILoginService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
@CrossOrigin
public class LoginController {
    @Autowired
    private ILoginService iLoginService;

    @RequestMapping("login")
    public People JudgeLogin(People people) {
        System.out.println(people.getAccountNumber()+"<----->"+people.getPassword());
//        String accountNumber = people.getAccountNumber();
//        String password = people.getPassword();
        People people2 = iLoginService.JudgeLogin(people);
        System.out.println("people2="+people2);
        if(people2!=null) return people2;
        else return null;
    }
}
