java - 无法使用 spring 和 java 7 启动 mule

问题描述

我是 mule 开发新手，我正在使用 java 7 开发使用 mule 的应用程序。

问题是我无法启动 mule，我不确定但查看日志，我认为我的 spring 配置和 mule 存在问题。

在日志中有一个代码错误：MULE_ERROR-71999 !!!。

这是日志：

我还尝试在 jre 1.8 下运行 mule，当我这样做时，我收到以下错误：

JDK Version 1.8.0_241 and/or Vendor Oracle Corporation are not supported. Please use a supported version: [1.6.0,1.7),[1.7.0,1.8).

任何帮助或建议将不胜感激。

解决方案

确定使用 Java 7 启动 Mule 3.4？可能该版本与 Java 8 不兼容，这可能会导致此错误。如果您使用的是 Anypoint Studio 或较旧的 Mule Studio，请确保执行环境指向 Java 7 SDK。

如果您使用的是命令行，则需要检查 wrapper.conf 是否指向 Java 7 的正确 java 可执行文件（示例wrapper.java.command=/path/to/jdk7/bin/java）。

3.4 绝对是生命的终结和古老，与 Java 7 相同。我建议尽快迁移到当前版本。
