项目结构示意图：

首先配置web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>SSMTesting</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

    <!-- 1注册servletContext监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- ================================================ -->


    <!-- 2启动Spring的容器，加载spring配置文件 -->
    <!-- 指定spring配置文件的位置及名称 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-*.xml</param-value>
    </context-param>
    <!-- ================================================ -->

    <!-- 3注册字符编码过滤器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- ================================================ -->

    <!--4springmvc的前端控制器，拦截所有请求 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 注意：进行如下contextConfigLocation配置，则可以不另外写springmvc-servlet.xml文件 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    <!-- ================================================ -->

</web-app>

另外，springmvc-servlet.xml文件的配置可以写，也可以不写，其配置如下：

<?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:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
        
    <!-- 注意：本文件可以写也可以不写，可以参照web.xml文件中的servlet中的contextConfigLocation配置 -->


    <!--SpringMVC的配置文件，包含网站跳转逻辑的控制，配置  -->
    <context:component-scan base-package="com.wg" use-default-filters="false">
        <!--只扫描Controller控制器。  -->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <!--配置视图解析器，方便页面返回  -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    
    <!--两个标准配置  -->
    <!-- 将springmvc不能处理的请求交给tomcat -->
    <mvc:default-servlet-handler/>
    <!-- 能支持springmvc更高级的一些功能，比如JSR303校验、快捷的ajax...映射动态请求 -->
    <mvc:annotation-driven/>

</beans>

dbconfig.properties文件配置数据库基本信息：

#数据库基本信息配置
jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/ssm?characterEncoding=utf8&useUnicode=true
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=123456

springMVC的配置如下：

spring-mvc.xml:

        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">
        
    <!-- 注册组件扫描器 -->
    <context:component-scan base-package="com.wg.controller"></context:component-scan>
    
    <!--配置视图解析器，方便页面返回  -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>

    <!-- 能支持springmvc更高级的一些功能，比如JSR303校验、快捷的ajax...映射动态请求 -->
    <mvc:annotation-driven/>
    
    

</beans>

spring的配置如下：

spring配置事务管理，spring-tx.xml：

    </bean>

</beans>

项目所需的jar包如下：

现在开始测试项目搭建是否成功，写一个增加数据的实例：

新建数据库ssm和数据库表student，结构如下：

新建如下图所示的包和类：

StudentController.java:

@Controller
public class StudentController {
    @Autowired
    public StudentService studentService;
    
    @RequestMapping("/test/register.do")
    public String register(Student student) {
        System.out.println("public String register(Student student)");
        studentService.studentRegister(student);
        return "success";
        
    }

}

StudentMapper.java

public interface StudentMapper {
    
    void studentRegister(Student student);

}

StudentMapper.xml

<?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.wg.mapper.StudentMapper">
  
  <insert id="studentRegister" parameterType="com.wg.pojo.Student">
    insert into student(name,age) values(#{name}, #{age})
  </insert>
  
</mapper>

Student.java

package com.wg.pojo;
/**
* @desc    自定义一个实体类
* @title   Student
* @author  75399
* @version 1.0
*/
public class Student {
    private Integer id;
    private String name;
    private int age;
    public Student(Integer id, String name, int age) {
        super();
        this.id = id;
        this.name = name;
        this.age = age;
    }
    public Student() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", age=" + age + "]";
    }
    
    

}

StudentService.java

public interface StudentService {
    
    void studentRegister(Student student);

}

StudentServiceImpl.java

@Service
public class StudentServiceImpl implements StudentService {
    
    @Autowired
    public StudentMapper studentMapper;

    @Override
    public void studentRegister(Student student) {
        // TODO Auto-generated method stub
        studentMapper.studentRegister(student);
    }

}

index.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>Insert title here</title>
</head>
<body>
<form action="${pageContext.request.contextPath}/test/register.do" method="post">
姓名：<input type="text" name="name"><br>
年龄：<input type="text" name="age"><br>
<input type="submit" value="注册">
</form>
</body>
</html>

新建views文件夹，新建success.jsp文件格式如下：

success.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>Insert title here</title>
</head>
<body>
success page!!!
</body>
</html>

现在可以运行项目，项目运行环境jdk1.8，tomcat8.0。

运行效果展示：

姓名是字符串，年龄输入整数，点击注册即可。

查看数据库表：

如果有不当的地方，还请评论。
