使用嵌入式 Tomcat 启动 Spring Boot 应用程序时，如何配置堆大小? [英] How can I configure the heap size when starting a Spring Boot application with embedded Tomcat?

问题描述

我正在尝试将 Spring Boot 支持的 Web 应用程序部署到生产环境中.该应用程序使用 Spring Boot 1.0.1 构建，并嵌入了默认的 Tomcat 7 作为应用程序服务器.使用 java -jar myapp.jar 命令行启动应用程序时，我想为应用程序分配更大的内存.

I am trying to deploy a Spring Boot powered web app to production. The app is built with Spring Boot 1.0.1 and has the default Tomcat 7 embedded as application server. I want to allocate larger memory to the app when start the app with java -jar myapp.jar command line.

我应该使用 JVM 参数，例如 -Xms -Xmx或使用环境变量，例如JAVA_OPTS?我试图在文档或谷歌中寻找答案，但没有得到答案.谁能给点提示?

Should I use JVM parameter such as -Xms -Xmx or use environment variable such as JAVA_OPTS? I have tried to look for the answer in documentation or google it, but I did not get an answer. Can anyone give some hints?

推荐答案

只需使用任何常规机制来设置 JVM.可在命令行上获取文档:

Just use whatever normal mechanism you would to set up the JVM. Documentation is available on the command line:

$ java -X
...
-Xms<size>        Set initial Java heap size
-Xmx<size>        Set maximum Java heap size
...
