我正在尝试在运行 Tomcat 5.5 + Java 1.5 的服务器中部署使用 Spring 3.1.2 构建的 Web 应用程序。这个应用程序在我的本地机器上运行良好，使用 Tomcat 6 + Java 1.6，你可以想象它不在服务器中。我可以用 JDK 1.5 编译我自己的类，但我不知道如何用 Spring 库来编译，知道吗？

更新：

在我的 pom.xml 中，我有这个以确保我使用 Java 1.5 进行编译：

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.5</source>
        <target>1.5</target>
    </configuration>
</plugin>

这是我得到的堆栈跟踪：

我认为您可能对为 Java 5 编译 Spring 类的必要性感到困惑。您不必重新编译 Spring（我很确定 Spring 3.x 仍在为 Java 5+ JVM 编译）。

我认为可能发生的情况是您的 war 文件包含为 Java 5 JVM 无法处理的 JDK6 编译的类。仔细检查项目的编译器设置以确保它正在创建 1.5 兼容的类文件。在 Eclipse 中，它位于 Project Properties/Java Compiler 区域中。对于 Ant，它是 javac 任务的一个属性。对于 Maven，它是编译器插件配置。

Package all spring jars in your "WEB-INF/lib".

Per Spring 3.1.2. Documentation: http://static.springsource.org/spring/docs/3.1.2.RELEASE/spring-framework-reference/html/new-in-3.0.html#new-in-3.0-intro

Java SE and Java EE Support

The Spring Framework is now based on Java 5, and Java 6 is fully supported.

Furthermore, Spring is compatible with J2EE 1.4 and Java EE 5, while at the same time introducing some early support for Java EE 6.
