所以我在新工作中继承了一个代码库，而这里唯一的其他 java 开发人员也很新。我正在尝试运行一个 spring-boot 项目，该项目需要文件并将内容插入数据库（据我所知），但在启动时出现以下错误：

`org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Missing table: header

主Application.java：

package com.mycompany.myproject.config;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.orm.jpa.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import javax.sql.DataSource;

@EnableAutoConfiguration
@Configuration
@ComponentScan(basePackages = "com.mycompany")
@EnableJpaRepositories("com.mycompany.myproject.database.repositories")
@EntityScan(basePackages = "com.mycompany.myproject.database.entities")
public class Application {

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

    @Bean(name = "primaryDataSource")
    @ConfigurationProperties(prefix = "datasource.primary")
    @Primary
    public DataSource configDataSource() {
        return DataSourceBuilder.create().build();
    }

}

它似乎认为缺少“标题”的 bean：

package com.mycompany.myproject.database.entities;

import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;

import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Table;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.FetchType;
import javax.persistence.OneToMany;
import javax.persistence.Temporal;

@Data
@Entity
@Table(name = "header")
public class Header extends EntityBase {

    @Column(nullable = false)
    @Temporal(javax.persistence.TemporalType.TIMESTAMP)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd hh:mm:ss")
    private Date startDate;

    @Temporal(javax.persistence.TemporalType.TIMESTAMP)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd hh:mm:ss")
    private Date endDate;

    @Column(nullable = false)
    private String processName;

    @Column(nullable = false)
    private String fileName;

    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "header")
    private List<Item> itemList;

}

我在这里搜索了所有我能找到的模糊相关的问题，但没有一个答案对我有用。

如果需要，很乐意发布更多代码或特定配置详细信息。

【问题讨论】：

该表是否真的存在于您的数据库中？
值得关注这篇帖子stackoverflow.com/questions/18716204/…
@elyor 我实际上无法弄清楚这是指向哪个数据库（任何有关其配置位置的线索将不胜感激）但目前有生产和 UAT 版本服务在不同的服务器上运行，所以我假设这些表是有序的。为了让事情变得更加混乱，我尝试将战争和 application.properties 从 UAT 服务器复制到一个新实例上，但在启动时我遇到了同样的错误（我可以在当前 UAT 服务器上重新启动而不会出现问题）。跨度>
@wayne649 您可以尝试找出您的休眠连接的数据库/主机实例（您可以编写日志或调试您的应用程序）。这里有一些提示：stackoverflow.com/questions/4351443/…
所以我在本地调试似乎找不到数据库信息，我想这可能是因为它没有设置。我试图弄清楚那里和工作服务器之间有什么不同，它似乎正在使用 HSQLDB 创建我认为是一个临时数据库，但这主要是我的猜测，我正在努力寻找背后的任何配置它。

【解决方案1】：

日志说：

Caused by: org.hibernate.HibernateException: Missing table: header

检查应用是否配置正确，表是否存在于 DDBB 中。

【解决方案2】：

原来生成的 hsqldb.script 文件中有问题，这意味着数据库用户身份验证失败，我仍然不完全确定出了什么问题或该文件是如何生成的，但我从其中一台工作的服务器允许服务启动。
