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 the runtime memory. (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:

• Added solon.test plugin
• Added solon-test-junit4 plug-in, relative to solon-test only supports junit4
• Added solon-test-junit5 plug-in, relative to solon-test only supports junit5
• Plug-in sentinel-solon-cloud-plugin console debugging
• The xml configuration of the plugin mybatis-solon-plugin is added ** expression support
• Adjusted AopContext::getProps() marked as deprecated, replaced by AopContext::cfg()
• Adjust Plugin::init() to Plugin::init(AopContext); Enhance support for solon cloud hot swap!!!
• Optimize the friendly prompt when the action parameter conversion fails
• Optimize the solon cloud plug-in to add support for hot swapping. Before, only the configuration of the main program can be used, but now the configuration of the plug-in can be used
• Optimize forest-solon-plugin to re-adapt in depth and support solon’s upstream!!!
• Optimize liteflow-solon-plugin re-deep adaptation!!!
• Optimize solon-test to add concurrent single test support for more scenarios!!!
• Optimize sa-token-solon-plugin to solve the problem that multiple StpLogic cannot be registered automatically
• Optimize the core global AopContext from the original static variable to the member variable of SolonApp!!!
• Optimize the core to support the running and switching of multiple SolonApps during the test to achieve the isolation effect of the single test!!!
• Optimize core Add Utils.resolvePaths(expr) for support /a/**/b/*.xml The resolution of this path
• Optimize core, adjust BeanWrap’s hashCode processing; and increase beanWrapsSet to collect name registration!!!
