maven-springmvc项目搭建

参考文章： https://www.cnblogs.com/qixing/p/qixing.html

1.新建project->Maven->Maven Project->next ->选中 maven-archetype-webapp->next ->填写项目信息 com.test ->finish

2.右击project->Properties(特性)->Project Facets->勾选Dynamic Web Module 3.0 ->点击下部 Further configuration availabe->填写 content directory: src/main/webapp,勾选Generate web.xml....

会在main下面生产webapp文件

3.修改pom.xml 添加依赖包 参考：

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.test</groupId>
    <artifactId>Test</artifactId>
    <packaging>war</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>Test Maven Webapp</name>
    <url>http://maven.apache.org</url>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.0.1</version>
            <scope>compile</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.1.2.RELEASE</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.1.2.RELEASE</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>
    <build>
        <finalName>Test</finalName>
    </build>
</project>

查看项目列表中 Maven Dependencies 下类库是否加载完成

4.右键项目名->Properties->Deployment Assembly remove /src/test/java /src/test/resouces

右键项目名->Properties->Deployment Assembly->Add -> Java Build Path Entries -> Next -> Maven Dependencies -> Finish -> Ok

5.修改web.xml和创建 servlet.xml文件
web.xml

<?xml version="1.0" encoding="UTF-8"?>
<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">

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-servlet.xml</param-value>
    </context-param>

</web-app>

spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans.xsd 
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd 
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 配置扫描的包 -->
    <context:component-scan base-package="com.test" />

    <!-- 注册HandlerMapper、HandlerAdapter两个映射类 -->
    <mvc:annotation-driven />

    <!-- 访问静态资源 -->
    <mvc:default-servlet-handler />

    <!-- 视图解析器 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

</beans>

6.编写 controller 和 view/jsp

DemoController.java

package com.test;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class DemoController {


    @RequestMapping("/index")
    public String index(){
        return "demo";
    }
}

demo.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>首页</title>
</head>
<body>
    <h1>This is SpringMVC Demo</h1>
</body>
</html>

7.右击->Run As-> Run on Server ->选择之前配置 tomcat->next-> 右侧Configured 显示项目 ->finish

eclipse console无错误后自动 自动打开内置浏览器，出现 Hello World!主页

输入http://localhost:8080/Hello/index 出现This is SpringMVC Demo正常页面成功
