repository.save（）

Question

我正在努力解决这个问题。我每次在repository.save（CustomerDetails）中添加主类时都会收到错误消息。当我点击错误时，我要求添加一个依赖项，但它并没有告诉我要添加的依赖项。

我怎么知道？

这是我的班级：

package com.example.Customer.Application;

import com.example.Customer.CustomerRepository.CustomerDetailRepository;
import com.example.Customer.Model.CustomerDetails;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import java.util.ArrayList;
import java.util.List;

@SpringBootApplication
public class AccountApplication {

    public static void main(String[] args) {

    }

    private void name(CustomerDetailRepository repository) {
        List<CustomerDetails> cd = new ArrayList<>();
        cd.add(new CustomerDetails(1, "Foo", "Bar"));
        cd.add(new CustomerDetails(2, "Foo1", "Bar1"));


        CustomerDetails cdd = new CustomerDetails(1, "a", "b");
        {

        }

        repository.save(CustomerDetails); this is where the error is. 

    }

}

这是我的主要课程：

package com.example.Customer.Model;

import com.example.Customer.CustomerApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;

import javax.annotation.Generated;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;


@Entity
public class CustomerDetails {


    private Long id;
    private String name;
    private String address;


    public CustomerDetails() {

      }

    public CustomerDetails(long id, String name, String address) {
        this.id = id;
        this.name = name;
        this.address = address;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

}

这是我的控制器代码

package com.example.Customer.Controller;

import com.example.Customer.Model.CustomerDetails;
import com.sun.org.apache.bcel.internal.generic.RETURN;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Generated;
import java.util.ArrayList;
import java.util.List;



@RestController
public class Customerapplication {

    @RequestMapping(method = RequestMethod.GET, path = "/findcustomer")
    public CustomerDetails createnewcustomerrecord() {

        return new CustomerDetails(1, "Sarah", "88 strong road");
    }

}

有任何帮助吗？你知道我可以添加什么依赖来修复这个bug吗？
