收到 org.postgresql.util.PGobject 类型的对象
Posted
技术标签:
【中文标题】收到 org.postgresql.util.PGobject 类型的对象【英文标题】：Received object of type org.postgresql.util.PGobject 【发布时间】：2018-02-20 04:50:10 【问题描述】：我可以从我的代码中将几何数据插入数据库，但我只能使用 SQL 编辑器（如 PGAdmin III）查询数据。我无法将几何数据检索回我的代码。每次尝试都以：“收到的 org.postgresql.util.PGobject 类型的对象”结束。即使运行一个简单的查询来测试两个几何值是否相等，我也会收到此错误。

在 persistence.xml 文件中，我使用了这个方言属性：
<property name="hibernate.dialect" value="org.hibernate.spatial.dialect.postgis.PostgisPG95Dialect"/>
PS：我已经尝试过 PostgisDialect
最后用一个简单的测试查询方法：
public void testar()
try
GeometryFactory gf = new GeometryFactory();
LinearRing shell = gf.createLinearRing(new Coordinate[]
new Coordinate(-43.56006145477295,-22.8861191211294), new Coordinate(-43.55607032775879,-22.8861191211294),

new Coordinate(-43.56006145477295,-22.8861191211294));
LinearRing[] holes = new LinearRing[0];
Polygon polygon = gf.createPolygon(shell, holes);
polygon.setSRID(4326);
Query q = entityManager.createQuery("from PontodeInteresse where equals(geometry, :geo) = true").setParameter("geo", polygon);
List<PontodeInteresse> pontos = q.getResultList();
catch(Exception e)
System.out.println(e.getMessage());
//try
我完全迷失在这里，没有想法。请帮忙。 谢谢
【问题讨论】：
createQuery() 需要一个 JPQL 查询。 JPQL 与 SQL 不是同一种语言。因此，就像您无法使用 C 编译器编译 Java 一样，您也无法使用 createQuery() 执行 SQL 查询。 @JBNizet，你能告诉我我的 JPQL 有什么问题吗？ 对不起。我读得太快了，错过了您使用 PostGis 方言的事实。我很抱歉。不过，您应该发布其完整且准确的堆栈跟踪，而不是仅仅发布异常消息。 好的@JBNizet。好建议。我刚刚更新了问题以提供堆栈跟踪。org.postgresql:postgresql 和 org.hibernate:* 依赖项应标记为 <scope>provided</scope>。它可能会从两个不同的类加载器中看到一个类型。
【参考方案1】：
在部署应用程序之前，您需要将 Postgis、hibernate-spatial 和其他相关库添加到 Wildfly，这是因为您使用的 hibernate 是与 wildfly 捆绑的，但其他库是与您的 war 捆绑的，所以他们使用不同的类加载器。
如果您检查this code，您可以看到转换是正确的，并且错误消息没有意义，这通常是类加载器的问题。
要解决此问题，您需要将所有库添加到 Wildfly，您可以这样做：
cd $JBOSS_PATH/modules/system/layers/base/org/hibernate/main
mvn dependency:copy -Dartifact=org.hibernate:hibernate-spatial:5.0.7.Final:jar -DoutputDirectory=.
mvn dependency:copy -Dartifact=org.geolatte:geolatte-geom:1.0.1:jar -DoutputDirectory=.
mvn dependency:copy -Dartifact=com.vividsolutions:jts:1.13:jar -DoutputDirectory=.
编辑module.xml 文件以添加您的部门：
<resource-root path="hibernate-spatial-5.0.7.Final.jar"/>
<resource-root path="jts-1.13.jar"/>
<resource-root path="geolatte-geom-1.0.1.jar"/>
并在依赖标签中添加：
<module name="org.slf4j"/>
另外如果你使用的是postgresql，你需要在依赖标签中添加：
<module name="org.postgresql"/>
在mvn 命令中使用正确的版本来下载正确的jar。
【讨论】：
再次感谢阿图罗。我将在这里留下一些关于我所做的细节： 再次感谢阿图罗。我将在这里留下一些关于我所做的细节：我使用的是 Hibernate 5.1.10.Final 附带的 Wildfly 11 CR1。因此，为了弄清楚应该下载哪些依赖项，我使用了“mvn dependency:tree”。我看到在我的情况下，我必须下载 geolatte-geom-1.0.6.jar、hibernate-spatial:5.1.10.Final、jts-1.13.jar 和 postgis-jdbc-2.2.1.jar。然后我一直按照你的指示去做。 @Maverick_Java 太棒了！您是直接在模块中还是在另一个模块中添加了 postgis jdbc？ 我将它添加到同一个模块中。回家后我会发布一个完整的示例。 @Maverick_Java 您能否发布“mvn dependency:tree”的输出，因为自 5.0 版以来，Hibernate Spatial 不再需要 postgis-jdbc jar。所以我很惊讶它仍然出现。【参考方案2】：这不仅适用于 Wildfly：我可以通过将 PostgreSQL jar 从 [tomcat]\webapps[WebApp]\WEB-INF\lib 移动到 [tomcat]\lib 来解决 Tomcat 上的相同问题。
顺便说一句：就我而言，问题只出现在客户的系统上；我们的开发服务器没问题 - 两种配置之间没有明显差异。
