java.lang.IllegalArgumentException：方法不能爲空

Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.beans.factory.config.PropertyPlaceholderConfigurer#0': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Method must not be null:java.lang.IllegalArgumentException: Method must not be null

我在部署我的應用程序時遇到此部署錯誤。java.lang.IllegalArgumentException：方法不能爲空

java -version 
java version "1.6.0_20" 
Java(TM) SE Runtime Environment (build 1.6.0_20-b02) 
Java HotSpot(TM) Server VM (build 16.3-b01, mixed mode)

而同一個構建被成功部署在相同的服務器碼頭6.1.3與以下conf。使用

java version "1.6.0_17"

春季版2.5.6.SEC01

如何克服，谷歌搜索沒有工作？

你能展示更多的堆棧跟蹤嗎？包括根本原因。 – Espen 2010-05-13 10:10:18

完整的堆棧跟蹤會有幫助，即'PropertyPlaceholderConfigurer'中的哪一行是這樣的？ – 2010-05-13 10:11:27

@abc：你可以編輯你的問題，並把堆棧跟蹤。 – 2010-05-13 10:26:53

這可能是由不同版本的Spring庫的髒類路徑導致的。清理它並將它與正確的版本依賴關係對齊到同一個Spring版本。

如果是這樣的話，那麼如何將相同的構建部署到另一個JVM？ – 2010-05-13 14:23:58

只需按照常規方式將庫存放在Web應用的'/ WEB-INF/lib'中。 JVM的lib或服務器庫。 – BalusC 2010-05-13 14:25:10

耶BalusC我做了同樣的事情，所有必需的庫都在/ WEB-INF/lib only.in Java版本「1.6.0_20」它拋出錯誤並且在具有java版本「1.6.0_17」的機器中工作良好，所有其餘配置保持原樣。相同的服務器，相同版本的服務器，相同的配置。） – 2010-05-13 14:37:11
