无法使用 Heroku postgres 将数据添加到 Spring Boot 上的数据库

【中文标题】无法使用 Heroku postgres 将数据添加到 Spring Boot 上的数据库

【英文标题】：Cant add data to databases on Spring Boot using Heroku postgres

【问题描述】：

我一直在尝试使用 Heroku 启动和运行 Rest 存储库。但是，当我正在使用的表被添加到数据源时，我无法上传任何数据行。

Shows that my tables are being added to postgres datasource

我没有收到任何错误消息或部署服务的问题，我只是无法添加数据。

我在互联网上寻找解决方案，目前 application.properties 是一堆不同的代码，我在所有指南中复制了如何让数据库运行。

#spring.h2.console.enabled=true
#spring.datasource.url=jdbc:h2:mem:testdb
#spring.datasource.driverClassName=org.h2.Driver
#spring.datasource.username=sa
#spring.datasource.password=
#spring.h2.console.settings.web-allow-others=true


#spring.main.banner-mode=off
#logging.level.org.springframework=ERROR

spring.jpa.hibernate.ddl-auto=update

#spring.datasource.initialization-mode=always
spring.datasource.platform=postgres
#spring.datasource.url=postgres://npwovtbfrmcgap:[e-mail]:5432/deu5uhuf0in93s
#spring.datasource.url=$JDBC_DATABASE_URL
#spring.datasource.username=$SPRING_DATABASE_USERNAME
#spring.datasource.password=$SPRING_DATABASE_PASSWORD
#spring.jpa.show-sql=true
#spring.jpa.generate-ddl=true
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
spring.datasource.url=$JDBC_DATABASE_URL
spring.datasource.username=$JDBC_DATABASE_USERNAME
spring.datasource.password=$JDBC_DATABASE_PASSWORD
spring.jpa.show-sql=false
spring.jpa.generate-ddl=true

为了测试，我使用了 h2，它运行良好，没有任何问题。尽管我一直在关注使用 JDBC _DATABASE 以便于设置，但我已经制作了一个数据库配置文件。

package com.example.chess.Config;


import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import javax.sql.DataSource;

@Configuration
public class DatabaseConfig 

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource()
    
        return new org.apache.tomcat.jdbc.pool.DataSource();
    

这里没有很多，但据我了解，如果我使用的是 JDBC 数据库，我不应该需要一个。

我的一些想法......

Heroku 可能会迫使我使用他们的指南来准备用于生产的 Spring Boot 应用程序 https://devcenter.heroku.com/articles/preparing-a-spring-boot-app-for-production-on-heroku

我可以在我拥有的表的代码上输入更好的 @GeneratedValue。

package com.example.chess.Model;


import javax.persistence.*;

@Entity
public class Chat 

    @GeneratedValue
    @Id
    @Column
    private int chatID;

    @Column
    private String chatMsg;

    public int getChatID() 
        return chatID;
    

    public String getChatMsg() 
        return chatMsg;
    

    public void setChatID(int chatID) 
        this.chatID = chatID;
    

    public void setChatMsg(String chatMsg) 
        this.chatMsg = chatMsg;
    

过去我不太确定该怎么做。感谢您提供任何反馈。

感谢所有帮助，但我仍然没有得到它的工作。我使用 heroku 日志来查找更多数据。我还使用了 spring.database.platform 和 spring.datasource.driver-class-name。应用程序属性的代码已更新。

【问题讨论】：

日志中有任何内容吗？可以尝试将 PostgreSQL 方言添加到应用程序属性中。

不幸的是我没有使用日志记录。我已将 spring.datasource.platform=postgres 添加到 application.properties，但没有成功。我还能添加什么？如果我仍然没有让它工作，我会研究日志记录以及我必须让它在原始问题中工作的其他想法。

您应该添加日志。如果您在日志中发现任何异常，那么您就知道从哪里开始调试。

【参考方案1】：

终于修好了。男孩，我觉得自己很笨吗，问题出在我发布并从 localhost:8080 获取的角度前端。

$http.get("http://localhost:8080/letter").then(function (response)

        $scope.letter = response.data;


    );

  $scope.postLetter = function(letter)
  
      var data = 
          contactName: contactName,
          email: email,
          message: message
      ;
      $http.post("http://localhost:8080/letter", JSON.stringify(data));
      location.reload();
  ;

再次感谢所有尝试提供帮助的人。

【参考方案2】：

尝试添加方言、驱动程序类名称和数据库平台，就像您评论的那样。
