java.lang.NoSuchMethodException：com.mchange.v2.c3p0.PoolBackedDataSource.setUserOverridesAsString（java.lang.String）

我正在使用C3P0 0.9.1.2爲我的連接池配置數據源。java.lang.NoSuchMethodException：com.mchange.v2.c3p0.PoolBackedDataSource.setUserOverridesAsString（java.lang.String）

上下文加載時會引發錯誤。這裏是跟蹤：

我已經用Google搜索了這個問題，但我什麼也沒找到。任何想法？ 有人知道c3p0中是否有bug？

看起來像你使用Spring。很可能是因爲您的Spring XML配置不正確，所以如果您可以發佈相關位，這將有所幫助。

類PoolBackedDataSource顯然沒有setUserOverridesAsString方法。也許你想上課ComboPooledDataSource？

我已經「失序」了幾天。我在這個問題的主體中添加了我的Spring XML配置中最相關的部分。 – Alberthoven 2009-12-10 17:49:45

聽起來好像您正在使用的c3p0 jar（通常與Hibernate一起使用）的較舊版本或較新版本比預期的要好...嘗試確保您的所有依賴關係都得到了滿足。
