该文档主要记录SpringMVC-Maven 搭建及发布到Tomcat7操做流程html

Round 1: 使用Eclipse建立Maven项目

建立名称SpringMVC-studyDemo的Maven项目前端

其中index.jsp报错，错误信息：Multiple annotations found at this line: - The superclassjava

意思是缺乏servlet包，咱们能够导入javax.servlet-api-3.1.0.jar包. 只须要在pom.xml中添加依赖便可web

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <!--有关jar包 依赖 可登陆http://mvnrepository.com/ 查询对应jar包-->
    </dependency>

Round 2: 引入Spring MVC

这里主要是在pom.xml中增长对Spring的依赖spring

<properties>
       	  <spring.version>5.0.8.RELEASE</spring.version>
  	 </properties>
     <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

Round 3: web.xml 启动支持Spring MVC

这里主要是在web.xml中增长对Spring的启动配置设计模式

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name>Archetype Created Web Application</display-name>
  <servlet>
    	<!--DispatcherServlet是前端控制器设计模式的实现，提供Spring Web MVC的集中访问点，并且负责职责的分派-->
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--servlet 加载配置文件-->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springContext.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
    <!--全局加载 配置文件-->
	<context-param>
		<param-name>contextConfigLocation</param-name>
        <!--此处能够配置多项-->
        <!--classpath默认为 src/main/resources-->
		<param-value>classpath:springContext.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
  
</web-app>

Round 4: 配置 springContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<!-- 搜索spring控件 -->
    <!-- 这里 base-package 地址为 src/main/java 下创建 默认 controller的包名-->
	<context:component-scan base-package="com.spring.mvc.controller"></context:component-scan>
	<!-- 视图页面配置 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/views/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>
</beans>

Round 5: 建立Spring控制器和视图

Controller 文件api

package com.spring.mvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;


@Controller
public class HelloWorldController {
	
	@RequestMapping("/helleworld")
	public ModelAndView hellWorld() {
		ModelAndView view=new ModelAndView("index.jsp");
		
		return view;
	}
}

jsp 文件tomcat

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
	<p>this is helloworld jsp</p>

</body>
</html>

Round 6: 编译项目发布部署

Maven installmvc

在\study-demo\target\目录下生成study-demo.war 可直接部署到tomcat/webapp目录下。 app

Round 7: Q&A
