SpringMVC源码解析一(在Spring源码项目中搭建SpringMVC源码模块)

1. 在Spring源码项目中右键,新建一个Module模块, 在弹窗中选择Gradle, 并且勾选Java和Web

2. 选择根目录并输入ArtifactId，点击确定 

3. 项目构建

  3.1 配置build.gradle

plugins {
    id 'java'
    id 'war'
}

group 'org.springframework'
version '5.0.16.BUILD-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile(project(":spring-beans"))
    compile(project(":spring-core"))
    optional(project(":spring-aop"))
    optional(project(":spring-context"))
    optional(project(":spring-oxm"))
    optional(project(":spring-jdbc"))
    optional(project(":spring-web"))
    optional(project(":spring-webmvc"))
    optional(project(":spring-test"))

    optional group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0'
    optional group: 'asm', name: 'asm', version: '3.3.1'
    optional group: 'junit', name: 'junit', version: '4.12'
    optional group: 'cglib', name: 'cglib', version: '2.2.2'
    optional group: 'org.jsoup', name: 'jsoup', version: '1.11.3'
    optional group: 'commons-dbcp', name: 'commons-dbcp', version: '1.4'
    optional group: 'mysql', name: 'mysql-connector-java', version: '5.1.38'

    optional("javax.annotation:javax.annotation-api:1.3.2")
    optional("javax.ejb:javax.ejb-api:3.2")
    optional("javax.enterprise.concurrent:javax.enterprise.concurrent-api:1.0")
    optional("javax.inject:javax.inject:1")
    optional("javax.interceptor:javax.interceptor-api:1.2.2")
    optional("javax.money:money-api:1.0.3")
    optional("javax.validation:validation-api:1.1.0.Final")
    optional("javax.xml.ws:jaxws-api:2.3.0")
    optional("org.aspectj:aspectjweaver:${aspectjVersion}")
    optional("org.codehaus.groovy:groovy:${groovyVersion}")
    optional("org.beanshell:bsh:2.0b5")
    optional("joda-time:joda-time:2.10")
    optional("org.hibernate:hibernate-validator:5.4.2.Final")
    optional("org.jetbrains.kotlin:kotlin-reflect:${kotlinVersion}")
    optional("org.jetbrains.kotlin:kotlin-stdlib:${kotlinVersion}")
    testCompile("org.codehaus.groovy:groovy-xml:${groovyVersion}")
    testCompile("org.codehaus.groovy:groovy-jsr223:${groovyVersion}")
    testCompile("org.codehaus.groovy:groovy-test:${groovyVersion}")
    testCompile("org.apache.commons:commons-pool2:2.6.0")
    testCompile("javax.inject:javax.inject-tck:1")
    testRuntime("javax.xml.bind:jaxb-api:2.3.0")
    testRuntime("org.glassfish:javax.el:3.0.1-b08")
    testRuntime("org.javamoney:moneta:1.3")
}

3.2  在resources资源文件下添加log4j.properties和spring-context.xml配置文件

  log4j.properties:

# Output pattern : date [thread] priority category - message   FATAL 0  ERROR 3  WARN 4  INFO 6  DEBUG 7
log4j.rootLogger=INFO, Console, RollingFile

#Console

log4j.logger.com.thinkgem.jeesite.modules.oa.dao.OaNotifyDao.findCount=WARN

spring-context.xml:

 3.3 在webapp下创建WEB-INF文件夹, 在WEB-INF下添加web.xml和spring-mvc-servlet.xml配置文件(spring-mvc为项目名)

  web.xml:

	
	spring-mvc

	
		org.springframework.web.context.ContextLoaderListener
	

	
		spring-mvc
		org.springframework.web.servlet.DispatcherServlet
		1
	
	
		spring-mvc
		/
	

	
		contextConfigLocation
		classpath:spring-context.xml
	

	
		characterEncodingFilter
		org.springframework.web.filter.CharacterEncodingFilter
		
			encoding
			UTF-8
		
		
			forceEncoding
			true
		
	
	
		characterEncodingFilter
		/
	

spring-mvc-servlet.xml:

4. 编写SpringMVC项目进行测试

  4.1 Model层

package com.lic.entity;

public class MyBean {
	private int age;
	private String name;

	public MyBean(int age, String name) {
		this.age = age;
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@Override
	public String toString() {
		return "MyBean{" +
				"age=" + age +
				", name='" + name + '\'' +
				'}';
	}
}

 4.2 View层, 在WEB-INF下新建pages文件夹并添加sayHello.jsp

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>



  
  


Hello world
姓名:${myBean.name}
年龄:${myBean.age}

 4.2 Control层

package com.lic.controller;

import com.lic.entity.MyBean;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class TestController {

	@RequestMapping("sayHello")
	@ResponseBody
	public ModelAndView sayHello(int age, String name) {
		ModelAndView mav = new ModelAndView();
		MyBean bean = new MyBean(age, name);
		mav.addObject("myBean", bean);
		mav.setViewName("sayHello");
		System.out.println(bean.toString());
		return mav;
	}
}

5. Tomcat启动配置, 以及启动

5.1  + -> TomcatServer -> local

5.2  启动程序命名 -> 选择Tomcat -> 设置项目名 -> 选择Java环境 

5.3  设置项目名 Deployment -> Application context 

5.4 浏览器输入地址: http://localhost:8080/spring-mvc/sayHello?age=12&name=lic

测试项目部署完成, 在该项目中引用的SpringMVC相关类都在源码项目中, 可以进行SpringMVC源码学习了!
