如何摆脱新表的自动安装

问题描述 投票:0回答:1

问题:当我通过bash控制台发出发布请求时,就会创建一个新表。其余查询转到新表。比他不喜欢那些可用的数据库。据我了解-他们只是不知道,但是我不知道如何正确地进行指导。尽管所有变量也都被命名。

发现由于Message类中的Entity注释而创建的问题。请告诉我如何将其添加到现有表中,并尝试将@Table(name = "ApiTable")添加到现有表中,并生成一个新的api_table。也不太了解为接受json发布请求需要添加/更改的内容。] >

应用程序

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EnableJpaRepositories("com.example.api")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

MainController

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller    
@RequestMapping(path="/demo") /
public class MainController {
    @Autowired
    private UserRepository TestApi;

    @PostMapping(path="/add")
    public @ResponseBody String addNewUser (@RequestParam String name
            , @RequestParam String email) {
        Message n = new Message();
        n.setName(name);
        n.setEmail(email);
        TestApi.save(n);
        return "Saved";
    }

    @GetMapping(path="/all")
    public @ResponseBody Iterable<Message> getAllUsers() {
        return TestApi.findAll();
    }

import javax.persistence.*;
