为什么JpaRepository.findAll（）方法从Oracle数据库中获取错误的数据？
[英]Why is the JpaRepository.findAll() method fetching the wrong data from my Oracle database?
问题描述
My Spring Boot application fetches the wrong data from my Oracle database, as in It retrieves the right amount of rows but the content is not correct (data is missing, other rows are [propably] duplicated). 
我的Spring Boot应用程序从Oracle数据库中提取了错误的数据，如中所述：它检索了正确数量的行，但是内容不正确（数据丢失，[适当地]重复了其他行）。
I'm new to Spring Boot and Oracle Databases. 我是Spring Boot和Oracle数据库的新手。 I read a lot of Tutorials and coded along. 我阅读了很多教程并进行了编码。 Now i try to create my first prototype of a webservice that fetches data from an Oracle 12c Database and makes them accessible via an HTTP Endpoint. 现在，我尝试创建Web服务的第一个原型，该原型从Oracle 12c数据库中获取数据，并使其可以通过HTTP端点进行访问。
I use SQL Developer to check the content of the table i want to display and it shows different stuff then in my Spring Boot application. 我使用SQL Developer检查要显示的表的内容，然后在Spring Boot应用程序中显示不同的内容。 I use Spring Boot 2.1.4. 我使用Spring Boot 2.1.4。
The table I want to display contains information about daily running cronjobs. 我要显示的表包含有关日常运行cronjobs的信息。
This is the Controller 这是控制器
import de.dat.verguetung.entity.DailyJobsEntity;
import de.dat.verguetung.service.DailyJobsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@CrossOrigin(origins = "http://localhost:4200")
@RestController
@RequestMapping("/dailyjobs")
public class DailyJobsController {
@Autowired
DailyJobsService dailyJobsService;
@CrossOrigin(origins = "*")
@RequestMapping(value = "/all", method = RequestMethod.GET)
public List<DailyJobsEntity> getAllDailyJobs() {
return dailyJobsService.getAllDailyJobs();
}
}
This is my Repository Interface 这是我的存储库界面
import de.prototype.entity.DailyJobsEntity;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface DailyJobsRepository extends JpaRepository<DailyJobsEntity, Integer> {
}
This is my model 这是我的模特
import javax.persistence.*;
import java.util.Date;
@Entity
@Table(name = "LOG_DAILY_JOBS")
public class DailyJobsEntity {
@Id
@Column(name = "JOB_TITLE", nullable = false, length = 100)
private String jobTitle;
@Column(name = "OK", nullable = false, length = 10)
private Integer ok;
@Column(name = "JOB_RESULT", nullable = true, length = 1000)
private String jobResult;
@Column(name = "EXECUTION_DATE", nullable = false)
@Temporal(TemporalType.DATE)
private Date executionDate;
protected DailyJobsEntity() {}
public DailyJobsEntity(String jobTitle, Integer ok, String jobResult, Date executionDate) {
this.jobTitle = jobTitle;
this.ok = ok;
this.jobResult = jobResult;
this.executionDate = executionDate;
}
public Date getExecutionDate() {return executionDate;}
public void setExecutionDate(Date executionDate) {this.executionDate = executionDate;}
public String getJobResult() {return jobResult;}
public void setJobResult(String jobResult) {this.jobResult = jobResult;}
public Integer getOk() {return ok;}
public void setOk(Integer ok) {this.ok = ok;}
public String getJobTitle() {return jobTitle;}
public void setJobTitle(String jobTitle) {this.jobTitle = jobTitle;}
}
This is my Service 这是我的服务
import de.dat.verguetung.dao.DailyJobsRepository;
import de.dat.verguetung.entity.DailyJobsEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class DailyJobsService {
@Autowired
DailyJobsRepository dailyJobsRepository;
public List<DailyJobsEntity> getAllDailyJobs(){
return this.dailyJobsRepository.findAll();
}
}
And this is my Main Class 这是我的主班
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class VerguetungApplication {
public static void main(String[] args) {
SpringApplication.run(VerguetungApplication.class, args);
}
}
The table has 156 rows. 该表有156行。 The application fetches 156 rows. 该应用程序获取156行。 Thats fine. 没关系。 But 95% of these rows are filled with the wrong content. 但是这些行中有95％填充了错误的内容。 I have a column named 'EXECUTION_DATE'. 我有一列名为“ EXECUTION_DATE”。 The entries for this column range from 2019-04-02 until 2019-04-16. 该列的输入范围为2019-04-02至2019-04-16。 The application displays every row with an execution date of 2019-04-02. 该应用程序显示执行日期为2019-04-02的每一行。
I can provide more details about the content of the table if needed. 如果需要，我可以提供有关表内容的更多详细信息。
I hope someone can help my and point out my mistakes. 我希望有人能帮助我并指出我的错误。 Thanks in advance :) 提前致谢 ：）
Edit: This is the content in the table: 编辑：这是表中的内容：

Edit 2 The code for printing the fetched rows 编辑2用于打印获取的行的代码
@CrossOrigin(origins = "http://localhost:4200")

If I'm not mistaken, your DailyJobsRepository uses DailyJobsRepository extends JpaRepository<DailyJobsEntity, Integer> to indicate that the primary key ID is of type Integer , while your entity DailyJobsEntity defines the ID to be of type String: 如果我没记错的话，您的DailyJobsRepository使用DailyJobsRepository extends JpaRepository<DailyJobsEntity, Integer>来表示主键ID的类型为Integer ，而您的实体DailyJobsEntity则将ID定义为String类型：
@Id
@Column(name = "JOB_TITLE", nullable = false, length = 100)
private String jobTitle;`
Is jobTitle the primary key of the entity? jobTitle是实体的主键吗？ Because I would expect the PK to be of type Integer. 因为我希望PK的类型为Integer。
