创建名称为'sessionFactory'的bean时出错：MalformedParameterizedTypeException

Question

任何建议将不胜感激。我难过…

问题

在我的笔记本电脑上，只要我们的应用程序尝试加载application-
config.xml，我都会收到java.lang.reflect.MalformedParameterizedTypeException。

完全相同的代码可在我的台式机和同事的台式机/笔记本电脑上使用。但是在我的笔记本电脑上，它将引发此错误。由于我的笔记本电脑和台式机是完全相同的开发环境（Mac
OS X Leopard上的Eclipse中的Java 1.6 Maven项目），我通过执行以下操作缩小了原因：

• 从Subversion签出了一个新项目（因此没有代码差异）
• 复制并替换了我的整个Eclipse目录（因此没有Eclipse版本/插件差异）
• 复制并替换了我的整个.m2目录（因此没有maven / project依赖项差异）

在一个地方而不是另一个地方可能导致此错误的原因是什么？以下是相关bean和错误的摘要…

                only the per-connection maximum. maxStatements controls the total number

                large number, as each pooled Connection requires its own, distinct flock 
                of cached statements. As a guide, consider how many distinct PreparedStatements 
                are used frequently in your application, and multiply that number by maxPoolSize 
                to arrive at an appropriate value. Though maxStatements is the JDBC standard 
                parameter for controlling statement caching, users may find c3p0's alternative 
                maxStatementsPerConnection more intuitive to use. -->

编辑：

更新-我只是找到了另一个线索，我们所有与数据库相关的JUnit测试都不起作用。在我的桌面上，它们全部通过。在我的笔记本电脑上，它们全部失败，但出现以下异常：

java.lang.NoSuchMethodError: org.springframework.beans.factory.annotation.InjectionMetadata.<init>(Ljava/lang/Class;Ljava/util/Collection;)V

任何建议都欢迎！谢谢！

Answer 1

我认为您的弹簧瓶有误-也许一个用于弹簧2.5，另一个用于3.0。例如，类加载器加载3.0版的spring-core，其余的加载2.5版。这将导致此类错误。

我建议仔细检查您的Maven依赖关系图并删除所有多余的依赖关系图。如有必要，请<exclusions>在pom中使用。

在此之前，请在所有计算机上清理项目。
