当我在macOS上运行IntelliJ IDEA 2021.1.2（终极版或社区版）时，我观察到所有网络接口（eth0、lo、…）上都有3个随机端口打开。一个随机端口由创意进程打开，另外两个端口由IntelliJ IDEA启动的不同java进程打开。

我已经删除了我明确安装的唯一插件SonarLint。

在端口63342上运行的调试器绑定到localhost这可以在首选项菜单中配置。

以下是lsof-i|grep LISTEN输出的相关部分：

    idea   3328    orto  187u  IPv4 0x3c332685aa6872fd   0t0  TCP localhost:6942 (LISTEN)
    idea   3328    orto  686u  IPv4 0x3c332685aa623815   0t0  TCP localhost:63342 (LISTEN)
    idea   3328    orto  752u  IPv4 0x3c332685aa676de5   0t0  TCP *:53212 (LISTEN)
    java   3341    orto   33u  IPv6 0x3c332685aa5f899d   0t0  TCP *:61070 (LISTEN)
    java   3341    orto   77u  IPv6 0x3c332685b9885edd   0t0  TCP *:53210 (LISTEN)

正如所问，这是ps-ef|grep 3341的相关部分（它是一个RemoteMavenServer）：

如何将这三个随机打开的端口绑定到localhost?

注释

• 这里创建了一个问题：https://youtrack.jetbrains.com/issue/IDEA-175889.
• IDEs Support（IntelliJ Platform）上有关于此问题的问题

==2023年3月28日更新==

使用IntelliJ 2022.3.3（终极版），我没有更多的TCP端口绑定到通配符接口。但是两个UDP端口仍然绑定到通配符接口，如CrazyCoder答案的屏幕截图所示。
