1.新建Maven工程，需要注意的是：在Archetype上，选择Artifact Id为maven-archetype-webapp的那项。

2.第一次构建Maven项目，会下载一些JAR包，由于Maven中央仓库速度太慢，我们选择阿里的镜像，在%MAVEN_HOME%/conf/settings.xml里，添加如下信息：（可选配置Maven本地仓库的地址。同样是在settings.xml里添加<localReposity>D:\Repositories\Maven</localReposity>）

除非你想每次下载JAR包都很慢，否则还是配置吧...

3.在Build Path里添加Tomcat的JAR包支持。成功之后的工程项目结构如图所示：

4.此时，已可以在Tomcat v8.5 Server at localhost里添加Guaipangpang项目，输入http://localhost:8080/Guaipangpang。如下图所示：

5.此时可以开始添加Spring，SpringMVC，Mybatis，MySQL，Druid，Log4j等支持。pom.xml依赖如下所示：

6.修改src/main/java/webapp/WEB-INF/web.xml

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <welcome-file>index.html</welcome-file>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

7.在src/main/resources下添加配置文件：

8.Java文件与JSP文件如下所示：

PersonController

package com.gpp.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.gpp.model.Person;
import com.gpp.service.IPersonService;

@Controller
@RequestMapping("/personController")
public class PersonController {
    
    private IPersonService personService;
    
    public IPersonService getPersonService() {
        return personService;
    }

    @Autowired
    public void setPersonService(IPersonService personService) {
        this.personService = personService;
    }

    @RequestMapping("/showPerson")
    public String showPersons(Model model){
        List<Person> persons = personService.loadPersons();
        model.addAttribute("persons", persons);
        return "showperson";
    }
}

PersonMapper

package com.gpp.dao;

import java.util.List;

import com.gpp.model.Person;

public interface PersonMapper {
    /**
     * 插入一条记录
     * @param person
     */
    void insert(Person person);
    
    /**
     * 查询所有
     * @return
     */
    List<Person> queryAll();
}

PersonMapper

<?xml version="1.0" encoding="UTF-8" ?>
 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.gpp.dao.PersonMapper">
    <!-- 查询所有person -->  
    <select id="queryAll" resultType="Person" >  
        select * from person  
    </select>
</mapper>

Person.java

package com.gpp.model;

/**
 * person 实体
 * @author Administrator
 *
 */
public class Person {

    private int id;
    private String name;
    private int age;
    
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;

    }
    
    @Override
    public String toString() {
        return "Person [id=" + id + ", name=" + name + "]";
    }
}

IPersonService

package com.gpp.service;

import java.util.List;

import com.gpp.model.Person;

public interface IPersonService {

    /**
     * 加载全部的person
     * @return
     */
    List<Person> loadPersons();
}

PersonServiceImpl

package com.gpp.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.gpp.dao.PersonMapper;
import com.gpp.model.Person;
import com.gpp.service.IPersonService;

@Service("personService")
public class PersonServiceImpl implements IPersonService {
    
    private PersonMapper personMapper;

    public PersonMapper getPersonMapper() {
        return personMapper;
    }
    @Autowired
    public void setPersonMapper(PersonMapper personMapper) {
        this.personMapper = personMapper;
    }
    
    public List<Person> loadPersons() {
        return personMapper.queryAll();
    }

    
}

9.项目结构如图所示：

11.输入http://localhost:8080/Guaipangpang/personController/showPerson。
即可得到如下所示的结果：

12.至此，由Maven搭建SSM框架正式完成。
