关于我的环境: Geoserver部署在容器上( enviroment 7，dev Jetty)，模块使用PostgreSQL9.xx。问题是，geoserver使用PostgreSQL8.4，我们在web/lib上用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，一切都很顺利。在dev env(jetty+netbeans)上，一切都很好，但是一旦在tomcat上部署了WAR，我就很高兴：

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

下面是导致上述情况的代码片段：

代码语言：javascript
复制
PGConnection pgDbconn = (PGConnection) dbConn;
LargeObjectManager largeObjectAPI = pgDbconn.getLargeObjectAPI(); // first method
LargeObjectManager lobj = new LargeObjectManager((BaseConnection) pgDbconn); // second - directly

根据我在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方法上所看到的，这两个jars都存在。你知道我为什么要得到NoSuchMethodError吗?解决方案是什么？

编辑:在web/lib上只有postgresql9.xxx。全叠迹

我解决了。在我的WEB/LIB上，这个违规的类是7KB JAR，名为postgis-stubs。可能是它被加载而不是postgresql，从而导致了NSME。后根的PGCONNECTION

谢谢@kayaman，谢谢第二个用户，他提到了加载错误的驱动程序。

那好吧。检查神秘的PGConnection类如下：

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

也许这会让你对问题有更多的了解。
