Spring源码-SpringMVC-搭建springmvc环境

一、新建模块myself-web
新建gradle的web项目，右键项目名，选择NEW-Moudle.

左边选择Gradle，右下选择web即可。

build.gradle

plugins {
id 'java'
id 'war'
id "com.bmuschko.tomcat" version "2.7.0"
}

group 'org.springframework'
version '5.3.6-SNAPSHOT'

repositories {
    maven { url 'https://maven.aliyun.com/repository/public/' }
    mavenLocal()
    mavenCentral()
    jcenter()
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine'
    implementation project(":spring-context")
    implementation project(":spring-beans")
    compile('org.aspectj:aspectjweaver:1.9.6')
    compile(project(":spring-web"))
    compile(project(":spring-webmvc"))

    providedCompile group: 'javax.servlet', name: 'javax.servlet-api', version: '4.0.1'
    implementation 'org.slf4j:slf4j-log4j12:1.7.32'
    implementation 'log4j:log4j:1.2.17'

    def tomcatVersion = '9.0.1'
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
            "org.apache.tomcat.embed:tomcat-embed-logging-juli:9.0.0.M6",
            "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}"
}

tomcat {
    httpPort = 8090
    httpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol'
    ajpProtocol  = 'org.apache.coyote.ajp.AjpNio2Protocol'
}

test {
    useJUnitPlatform()
}

使用tomcat插件，地址是https://github.com/bmuschko/gradle-tomcat-plugin

二、项目结构

IndexController.java

@Controller
@RequestMapping("/")
public class IndexController {

	@RequestMapping("/main")
	public ModelAndView index() {
		Date date=new Date();
		ModelAndView modelAndView=new ModelAndView();
		modelAndView.addObject("date",date);
		modelAndView.setViewName("main");
		return modelAndView;
	}

}

app-mvc.xml

							use-default-filters="true">
		<context:exclude-filter type="annotation"

	</context:component-scan>

</beans>

log4j.properties

项目结构如下：

下图中

点击tomcatRunWar运行项目

浏览器访问http://localhost:8090/myself-web/main,结果如下
