Full Stack Java Web Application Framework with Java & HTML5 - GitHub - axboot/ax-boot-framework: Full Stack Java Web Application Framework with Java & HTML5
打开之前创建好的 dev space，如果没有，新创建一个。类型要选择成 Full Stack Cloud Application：进入 space 之后，我们在浏览器里看到了一个类似 Visual Studio Code 的在线编辑器，打开一个新的命令行窗口：我们当前的工作目录为：/home/user/projects:运行如下命令行：mvn -B archetype:generate -D...

1、通过jstat命令监控GC情况,看到Full GC次数非常多,并且次数在不断增加。说明jvm在做fgc引起。但是fgc不足引起jvm进程占用cpu高达2500%。 我们增加堆内存: 修改堆内存 -Xmx16g -Xms16g -Xmn4G。问题没有解决,还是出现大量fgc。 修改堆内存 -Xmx32g -Xms32g -Xmn4G。问题没有解决,还是出现大量fgc。
这些成型的full-stack框架,加上最经典的Java full-stack框架……Hibernate/Spring/Struts组合(或者Hibernate/Spring/Webwork组合),一夜之间,Java开源世界的full-stack框架如千树万树梨花开,让我们这些Java开发人员挑花了眼,有人说,选择太多,即是Java开发人员之福,也是Java开发人员之痛,如何挑选适合自己需要的框架,则成为...
Creating complex Java applications from scratch takes a lot of time, and adding a framework to your stack simplifies this process. There are many common functionalities that almost every application needs, like data retrieval, security, or privacy. The best Java frameworks include many of these fea...
