使用spring boot jpa存储库时出现Stackoverflow错误

【问题标题】：Stackoverflow error while using spring boot jpa repository使用spring boot jpa存储库时出现Stackoverflow错误

【问题描述】：

我正在尝试使用 Spring Boot 在 Spring Boot 中使用 JpaRepository 从 DB 获取数据。它适用于 findById 但对于 findAll StackOverflow 错误返回。 find 实现还有什么需要实现的。

我试图从数据库中获取的工作模型。

@Entity
@Table(name="job_table")
public class Job
{
  @Id
  private int id;
  private String status;
  private String type;
  private String data;
}

Repository 接口实现如下：

public interface JobRepository extends JpaRepository<Job, Integer>, JpaSpecificationExecutor<Job>
    {

    }

调用是使用 JPASpecifications 进行的：

Specification<Job> jobSpecification =null;
    if(allRequestParams.containsKey("status")){
      logger.info("Status :{}",allRequestParams.get("status"));
      jobSpecification =  jobSpecification.and(withStatus(allRequestParams.get("status").trim()));
    }
Iterable<Job> jobList=jobRepository.findAll(jobSpecification);

我得到以下堆栈跟踪：

   Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.StackOverflowError] with root cause

【问题讨论】：

  • 我认为您需要发布有关您的 Job 和 jobSpecification 对象的更多信息。可能有一些循环调用
  • @laabidiRaissi 我已根据您的要求添加了更多信息。当我使用 .findAll() 时，我也面临同样的问题。现在我的数据库只有一条记录。

标签： java spring spring-boot spring-data-jpa


【解决方案1】： 
org.hibernate.query.criteria.internal.QueryStructure.from(QueryStructure.java:134)

此代码从类路径加载查询的 EntityType，并且似乎存在与类加载相关的一些循环问题。类似（不准确）的问题here 似乎是 jar 文件的不当打包导致了此类问题。

【讨论】：

  • 它似乎不起作用。我有一个非常简单的实体描述。
  • 您能否在 github 上以尽可能少的代码以及可以重现此问题的构建文件共享您的代码。这将是帮助解决问题的最快方法。
【解决方案2】：

尝试将标识符更改为 Integer 而不是 int。
