Spring Boot / JPA：为什么 war 转换中断功能 and/or JPA 搜索？

Question

我是运行一个基于社区版Broadleaf Commerce演示站点（辣酱）的应用。

为了试验 CI 和部署选项，我们已按照 broadleaf and spring 文档将库存 spring 引导包（jar）转换为 war。

转换后，应用程序将正常启动，但似乎某些数据库 (JPA) 交互已中断（搜索和数据库更新时出错）。

我有几个相关的问题：

当从 jar 转换为 war 时，initialize/access JPA（通过 Hibernate）资源是否需要额外的配置或注意事项？spring 文档中指定的内容以上？
运行通过 Maven 目标 mvn spring-boot:run（成功）与运行 java -jar <war-file> 之间有什么区别（失败）？
特别是与我看到的关于 JPA 标准路径的错误（复制在下面）相关，我发现这个 SO post 表明它可能是一个实现问题。但回到问题 #2，如果是这样的话，如果是代码问题，为什么我运行应用程序的方式很重要？

可能相关的信息：

我已验证数据库正在通过其他客户端响应。

错误信息：

Spring 引导应用程序配置文件：

  @SpringBootApplication
  @EnableAutoConfiguration
  public class SiteApplication extends SpringBootServletInitializer {

    @Configuration
    @EnableBroadleafSiteAutoConfiguration
    public static class BroadleafFrameworkConfiguration {}

      @Override
      protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SiteApplication.class);
      }

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

存档状态class（根据错误消息）

@Embeddable
public class ArchiveStatus implements Serializable, SandBoxNonProductionSkip {

    @Column(name = "ARCHIVED")
    @AdminPresentation(friendlyName = "archived", visibility = VisibilityEnum.HIDDEN_ALL, group = "ArchiveStatus")
    protected Character archived = 'N';

    public Character getArchived() {
        return archived;
    }

    public void setArchived(Character archived) {
        this.archived = archived;
    }
}

产品Class（嵌入存档状态）

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@javax.persistence.Table(name = "BLC_PRODUCT")
//multi-column indexes don't appear to get exported correctly when declared at the field level, so declaring here as a workaround
@org.hibernate.annotations.Table(appliesTo = "BLC_PRODUCT", indexes = {
        @Index(name = "PRODUCT_URL_INDEX",
                columnNames = {"URL", "URL_KEY"}
        )
})
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region = "blProducts")
... (BLC-specific overrides ommitted) ...
public class ProductImpl implements Product, ProductAdminPresentation, Status, AdminMainEntity, Locatable, TemplatePathContainer {
    ...
    @Embedded
    protected ArchiveStatus archiveStatus = new ArchiveStatus();
    ...
}

DAO 方法：

    public List<SearchFacet> readAllSearchFacets(FieldEntity entityType) {
        CriteriaBuilder builder = em.getCriteriaBuilder();
        CriteriaQuery<SearchFacet> criteria = builder.createQuery(SearchFacet.class);

        Root<SearchFacetImpl> facet = criteria.from(SearchFacetImpl.class);

        criteria.select(facet);

        Path<Character> archived = facet.get("archiveStatus").get("archived");

        criteria.where(
                builder.equal(facet.get("showOnSearch").as(Boolean.class), true),
                builder.or(builder.isNull(archived.as(String.class)),
                           builder.notEqual(archived.as(Character.class), 'Y')),
                facet.join("fieldType")
                        .join("indexField")
                        .join("field")
                        .get("entityType")
                        .as(String.class)
                        .in(entityType.getAllLookupTypes())
        );

        TypedQuery<SearchFacet> query = em.createQuery(criteria);
        query.setHint(QueryHints.HINT_CACHEABLE, true);
        query.setHint(QueryHints.HINT_CACHE_REGION, "query.Search");

        return query.getResultList();
    }

Answer 1

我在运行 DemoSite 通过编译的 jarfile 时发现了同样的错误。

看看这个话题：https://github.com/BroadleafCommerce/DemoSite/issues/51

在我的例子中，我必须在站点的 pom.xml 中包含 spring-instrument 依赖项，并使用 -javaagent 参数指定其 jar 位置：

$ java -Xmx1024m -javaagent:./path/to/spring-instrument.jar -jar site.jar
