A more modern framework for Java application development: faster, smaller, and freer. No Spring, no Servlet, no JavaEE;Independent lightweight ecology. The main frame is only 0.1 MB.

@Controller
public class App {
    public static void main(String[] args) {
        Solon.start(App.class, args);
    }

    @Get
    @Socket
    @Mapping("/hello")
    public String hello(@Param(defaultValue = "java") String name) {
        return String.format("Hello %s!", name);
    }
}

Getting started exploration video (user recorded):

Projects relative to Spring Boot and Spring Cloud:

• Startup is 5 to 10 times faster. (faster)
• qps is 2 to 3 times higher. (higher)
• Save 1/3 ~ 1/2 of memory at runtime. (less)
• Packing can be reduced to 1/2 ~ 1/10; for example, 300Mb becomes 23Mb. (smaller)
• Registration discovery based on service name corresponds to k8s svc
• Support Service Mesh architecture deployment scheme
• Support jdk8, jdk11, jdk17, jdk19 at the same time
• No Spring, no Servlet, no JavaEE; independent lightweight ecology

This update:

• Add fastdfs-solon-cloud-plugin plugin
• Plug-in file-s3-solon-plugin increases content size acquisition
• Plug-in aws-s3-solon-plugin increases content size acquisition
• Add CloudFileService::exists(…) and CloudFileService::getTempUrl(…) interfaces
• Add Meda::contentSize() and DownloadedFile::getContentSize() interfaces
• Add Media::bodyAsBytes() interface, the old Media::bodyAsByts() is marked as deprecated
• Add core detection of startup class and package name
• Add server.wrapHost, server.wrapPort configuration support! ! ! (more friendly to docker monomer registration and discovery)
