创建名为“sessionFactory”的 bean 时出错：MalformedParameterizedTypeException答案

【问题标题】：Error creating bean with name 'sessionFactory' : MalformedParameterizedTypeException创建名为“sessionFactory”的 bean 时出错：MalformedParameterizedTypeException

欢迎任何建议。我被难住了……

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桌面和我同事的桌面/笔记本电脑。但是在我的笔记本电脑上它会抛出这个错误。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）

什么可能导致这个错误在一个地方而不是另一个地方？下面是相关 bean 的 sn-p 和错误...

                to arrive at an appropriate value. Though maxStatements is the JDBC standard

编辑：

更新 - 我刚刚发现了另一个线索，我们与数据库相关的 JUnit 测试都不起作用。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，但有以下例外：

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！

【问题讨论】：

我认为是@Bozho 和其他人。我知道这不太可能，但是您确定两个 CLASSPATH 环境变量相同吗？

标签： java eclipse hibernate spring maven-2

【解决方案1】：

我会假设你有错误的弹簧罐 - 也许一个用于 spring 2.5 和一个用于 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。

我建议检查您的 maven 依赖关系图并删除所有冗余的依赖关系图。如有必要，请在您的 pom 中使用<exclusions>。

在此之前清理所有机器上的项目。

【讨论】：

我也想过。但是为什么行为与其他机器不一致？
@Pascal - 可能是最近没有清理那里的构建。或者（这是一个疯狂的猜测）Mac JVM 的类加载器正在以不同的顺序加载 jar。
很可能在正确的轨道上；它抱怨的方法 - 构造函数 InjectionMetadata(Class, Collection) - 仅存在于 3.0 中。
嗯，显然某处有鬼。我只是看不到它在哪里。
事实证明，简而言之，代码是使用两个不同的类路径编译和执行的。当然，实际问题要复杂几个数量级。当我手动编译并运行 JUnit 测试时，它运行良好！基本问题是，AspectJ 插件使用其类路径处理编译，而我在 JUnit 中的运行配置使用了一个极其不同的类路径（以及 spring jar 的版本）。运行配置（默认情况下不受版本控制）是两台机器略有不同的一件事。

【解决方案2】：

尝试在嵌入在 Tomcat 中的 Mule ESB 上运行 Mule 服务时，我遇到了类似的错误。解决方案是更改默认的 JDK：

java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8.1) (6b18-1.8.1-0ubuntu1)
OpenJDK 64-Bit Server VM (build 16.0-b13, mixed mode)

致老 Sun JDK：

java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

当然，可能是版本/补丁问题。要是我有时间去调查就好了……

【讨论】：

【解决方案3】：

我遇到了同样的问题，另一个措施有所帮助：删除整个 .metadata 文件夹。稍后从他们的地方导入项目或从 svn 签出它们（如果你使用一些）。问题是我们真的不知道，哪些元数据被破坏了，所以下一步自然是删除所有这些元数据。我认为，除了重新安装 Eclipse + 插件之外，这是最深入的清理。
