我们将不胜感激任何建议。我很难过...

问题

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

完全相同的代码适用于我的台式机和我同事的台式机/笔记本电脑。但是在我的笔记本电脑上它抛出了这个错误。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 Eclipse 中的 Java 1.6 Maven 项目)，我通过执行以下操作缩小了原因范围:

  • 从 Subversion checkout 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 依赖差异)

可能是什么原因导致这个错误发生在一个地方而不是另一个地方？下面是相关 bean 和错误的片段......

                only the per-connection maximum. maxStatements controls the total number 
                of Statements cached, for all Connections. If set, it should be a fairly 
                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 - 我刚刚发现了另一条线索，我们与数据库相关的 JUnit 测试均无效。在我的桌面上，它们都通过了。在我的笔记本电脑上，它们都失败了，但出现以下异常:

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

欢迎提出任何建议!谢谢!

最佳答案

我假设您的 spring jar 有误 - 也许一个用于 spring 2.5，另一个用于 3.0。类加载器为 3.0 版本加载 spring-core，为 2.5 加载其余部分。这将导致此类错误。

我建议检查您的 Maven 依赖关系图并删除所有冗余的。如有必要，请使用 <exclusions>在你的 pom 中。

在此之前清理所有机器上的项目。

关于java - 创建名称为 'sessionFactory' 的 bean 时出错 : MalformedParameterizedTypeException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3971219/
