java.lang.IllegalArgumentException：不支持的类文件主要版本 58

Question

我已经在 Eclipse 中包含了 TomEE，以便开始开发动态 Web 项目（我还是新手）。

在将项目添加到 TomEE 服务器之前，我可以毫无问题地启动它。

但是当我将项目添加到服务器并尝试运行它时，我收到错误： java.lang.IllegalArgumentException: Unsupported class file major version 58

我试图做的是为了解决它：

• 更改服务器端口号
• 删除并重新创建服务器
• 检查web.xml文件以确保 servlet 映射正常
• 重新配置项目的目标运行时
• 重新配置eclipse的运行环境

版本：

• TomEE: v8.0.3 羽
• JDK：15.0.1
• 日食：4.17.0

测试项目代码

测试服务程序

package my.test.project;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class TestServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.println("Hello this is a test");
        out.close();
    }
}

项目方面

非常感谢我的帮助，因为我已经使用了很长一段时间，但似乎无法弄清楚问题是什么。

谢谢你。

Answer 1

您提到您的版本是 JDK: 15.0.1，项目的 Java Facet 是 14。

供参考：

• Java 13 使用主要版本 57
• Java 14 使用主要版本 58
• Java 15 使用主要版本 59
• Java 16 使用主要版本 60

可以通过以下方式检查版本：

javap -verbose MyClass | grep "major"
