我是靠谱客的博主无辜项链，最近开发中收集的这篇文章主要介绍springmvc-源码调试-1配置建立Demo问题后言，觉得挺不错的，现在分享给大家，希望可以做个参考。

配置

参考之前文章导入源码等文章
新建Mdel，
修改当前项目的build.gradle
添加下面内容

plugins {
    id 'java'
}

group 'org.springframework'
version '5.3.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    compile(project(":spring-beans"))
    compile(project(":spring-oxm"))
    compile(project(":spring-aspects"))
    compile(project(":spring-core"))
    compile(project(":spring-aop"))
    compile(project(":spring-web"))
    compile(project(":spring-webmvc"))
    compile(project(":spring-context"))
    compileOnly 'org.projectlombok:lombok:1.18.6'
    annotationProcessor 'org.projectlombok:lombok:1.18.6'
    compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.5.32'
    compile group: 'com.alibaba', name: 'fastjson', version: '1.2.47'
    compileOnly group: 'junit', name: 'junit', version: '4.8'
}
tasks.withType(JavaCompile) {
    options.encoding = "UTF-8"
}

建立Demo

建立Controller

@RestController("test")
public class TestController {


    public TestController() {
        System.out.println("初始化成功过");
    }

    @RequestMapping("test")
    public void test() throws Exception {
        System.out.println("cc");
    }
}

建立启动类

为了方便，我是代码调试

@ComponentScan
public class AnnotatedBeanDefinitionReaderContext {

    public static void main(String[] args) throws LifecycleException {
        File base = new File(System.getProperty("java.io.tmpdir"));
        Tomcat tomcat = new Tomcat();
        tomcat.setPort(8080);
        tomcat.addContext("/",base.getAbsolutePath());
        tomcat.start();
        Wrapper wrapper = tomcat.addServlet("/","app",getDispatcherServlet());
        wrapper.setLoadOnStartup(1);
        wrapper.addMapping("/");
        tomcat.getServer().await();

    }


    public static DispatcherServlet getDispatcherServlet() {
        //容器添加需要启动的ApplicationContext
        AnnotationConfigWebApplicationContext annotationConfigWebApplicationContext
                = new AnnotationConfigWebApplicationContext();
        annotationConfigWebApplicationContext.register(AnnotatedBeanDefinitionReaderContext.class);
        annotationConfigWebApplicationContext.refresh();
        return new DispatcherServlet(annotationConfigWebApplicationContext);
    }

}
