如何将IntelliJ思想随机打开的端口绑定到本地主机？

Question

当我在IntelliJ上运行macOS IDEA 2021.1.2 (终极版或社区版)时，我发现所有网络接口(eth0，lo，.)上都开放了3个随机端口。一个随机端口由IDEA进程打开，另外两个端口由IntelliJ idea启动的不同java进程打开。

我已经删除了唯一显式安装的插件，即SonarLint。

在端口63342上运行的调试器绑定到本地主机，这可以在Preferences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)

如前所述，以下是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本地主机？

备注

• 这里创建了一个问题：https://youtrack.jetbrains.com/issue/IDEA-175889。
• 在 IDEs Support (IntelliJ Platform)上有一个关于这个问题的问题

Answer 1

默认情况下，IntelliJ IDEA不绑定通配符接口上的任何端口，除了UDP并发许可检查(仅用于最终授权)。用于内部需要的所有端口(Netty库初始化、独占文件夹锁定、内置web服务器、调试器、编译器/maven/gradle/运行process )都是在localhost (127.0.0.1)接口上打开的：
