Question

关于我的环境的几句话： Geoserver部署在容器（env Tomcat 7，dev Jetty）上，模块使用postgresql 9.xx. 事实是，geoserver使用postgresql 8.4，我们用web-inf / lib上的9.3替换它（不要问为什么等等）在我需要从Postgres引入LargeObjects处理之前，一切都运行良好。在dev env（jetty + netbeans）上一切都很好，但是一旦在tomcat上部署了WAR，我就会发现：

java.lang.NoSuchMethodError：     org.postgresql.PGConnection.getLargeObjectAPI（）Lorg / PostgreSQL的/ largeobject / LargeObjectManager;

以下是导致上述内容的代码段：

PGConnection pgDbconn = (PGConnection) dbConn;
LargeObjectManager largeObjectAPI = pgDbconn.getLargeObjectAPI(); // first method
LargeObjectManager lobj = new LargeObjectManager((BaseConnection) pgDbconn); // second - directly

我在http://grepcode.com/file/repo1.maven.org/maven2/postgresql/postgresql/8.4-702.jdbc4/org/postgresql/PGConnection.java#PGConnection.getFastpathAPI%28%29和http://grepcode.com/file/repo1.maven.org/maven2/org.postgresql/postgresql/9.3-1102-jdbc41/org/postgresql/PGConnection.java#PGConnection.getLargeObjectAPI%28%29上看到的内容方法存在于两个罐子里。任何想法为什么我得到NoSuchMethodError，并解决方案是什么？

编辑：只有web-inf / lib上的postgresql9.xxx。完整的堆栈跟踪

Answer 1

那么好吧。检查你的神秘PGConnection类如下：

PGConnection pgDbconn = (PGConnection) dbConn;
Class<PGConnection> clazz = pgDbconn.getClass();
for(Method m : clazz.getDeclaredMethods()) {
   log.info(m.getReturnType() + " " + m.getName());
}

也许这会对你的问题有所了解。

Answer 2

我解决了。在我的WEB-INF / LIB上，违规类是7KB JAR，名为postgis-stubs。可能它被加载而不是postgresql，导致NSME。 PGCONNECTION from postgis stubs

感谢@kayaman，感谢第二位用户，他提到了错误的驱动程序已加载。
