整合的思路是：

   先创建spring框架

   通过spring整合spring mvc

   通过spring整合mybatis

工程创建

   创建Maven工程–>create for archtype–>webapp

创建项目结构

在recourses目录下创建 dbconfig.properties、log4j.properties、mysqlConfig.xml、springmvc.xml、applicationContext.xml

在pom.xml添加相关依赖

基本思路

建立spring框架

1.创建实体

public class user implements Serializable {private Integer id;private String name;private String gender;private String email;@Overridepublic String toString() {return "user{" +"id=" + id +", name='" + name + '\'' +", gender='" + gender + '\'' +", email='" + email + '\'' +'}';}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 String getGender() {return gender;}public void setGender(String gender) {this.gender = gender;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}
}

 2.创建DAO

public interface userDao {public List findAll();
}

3.userService的接口

package club.twzw.service;import club.twzw.bean.User;
import org.springframework.stereotype.Service;import java.util.List;public interface UserService {public List findAll();}

4.实现userServiceImpl,并给userServiceImpl 起别名userService

@Service("userService")		
public class userServiceImpl implements userService {@Overridepublic List findAll() {System.out.println("查询所有用户。。。");return null;//service.findAll();}
}

5.在resources文件下创建文件applicationContext.xml

6.书写测试方法

    @Testpublic void testQueryUserList() {ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");userService service = (userService) ac.getBean("userService"); // 因为给service起了别名，所以通过id的方式获取classservice.findAll();}

运行效果：

建立spring mvc

在web.xml文件中修改并配置过滤器，中文乱码过滤

spring-dispatcherorg.springframework.web.servlet.DispatcherServletcontextConfigLocationclasspath:springmvc.xml1spring-dispatcher/characterEncodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingUTF-8characterEncodingFilter/

在resources文件夹下创建springmvc.xml文件,开启注解扫描，视图解析器以及过滤静态资源和springmvc注解支持

书写controller

package club.twzw.controller;import club.twzw.bean.User;
import club.twzw.service.UserService;
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 java.util.List;@Controller
public class UserController {@Autowiredprivate UserService service;@RequestMapping("/findAll")public String findAll(Model model){System.out.println("success");List all = service.findAll();model.addAttribute("user",all);return "list";}
}

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
查看所有用户

success.jsp

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

页面如果做成显示，自此已成功添加spring mvc框架

在整合之前需要明白，我们需要在controller中调用service，最快捷的便是使用依赖注入，而至今使用Tomcat服务器只加载了springmvc.xml文件，并没有applicationContext.xml的加载（也就是spring并没有被加载），所以可以通过监听ServeltContext域对象，在创建时加载spring的配置文件（applicationContext.xml）

配置监听器

在web.xml文件下添加listener,context-param设置监听和applicationContext.xml的文件路径

    					<<<<------org.springframework.web.context.ContextLoaderListener											<<<<------contextConfigLocationclasspath:applicationContext.xmlspring-dispatcherorg.springframework.web.servlet.DispatcherServletcontextConfigLocationclasspath:springmvc.xml1spring-dispatcher/characterEncodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingUTF-8characterEncodingFilter/

这样我们就可以使用依赖注入了

使用依赖注入并从新发布,如果正常，就可以在控制台看到两句话

package club.twzw.controller;
import club.twzw.service.impl.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
public class UserController {@Autowiredprivate UserService service;@RequestMapping("/findAll")public String findAll(){System.out.println("success");service.findAll();return "success";}
}

这样spring mvc 就已经整合完毕了

建立mybatis环境

在UserDao中使用注解查询

package club.twzw.dao;import club.twzw.bean.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;import java.util.List;
@Repository
public interface UserDao {@Select("select * from user")public List findAll();}

创建mybatis的核心配置文件mysqlConfig.xml

书写测试方法

    @Testpublic void test() throws IOException {InputStream resourceAsStream = Resources.getResourceAsStream("mysqlConfig.xml");SqlSessionFactoryBuilder builder = new SqlSessionFactoryBuilder();SqlSessionFactory factory = builder.build(resourceAsStream);SqlSession session = factory.openSession(true);UserDao mapper = session.getMapper(UserDao.class);List all = mapper.findAll();for (User user : all) {System.out.println(user);}}

输出结果：

说明了mybatis可用，那么可以开始整合了
整理mybatis,思路相同，同样使用依赖注入，将mysqlConfig.xml添加到容器中，并自动注入

在spring的文件中整合mybatis,配置连接池，factory，dao所在的包,此时有无将mysqlConfig.xml都不重要！

使用依赖注入

在dao类上添加@Repository注解

@Repository
public interface UserDao {@Select("select * from user")public List findAll();
}

在serviceimpl中注入接口

package club.twzw.service.impl;import club.twzw.bean.User;
import club.twzw.dao.UserDao;
import club.twzw.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;
@Service("UserService")
public class UserServiceImpl implements UserService {@Autowiredprivate UserDao dao;public List findAll() {System.out.println("查询所有用户。。。");return dao.findAll();}
}

修改controllerfindAll方法

package club.twzw.controller;import club.twzw.bean.User;
import club.twzw.service.impl.UserService;
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 java.util.List;@Controller
public class UserController {@Autowiredprivate UserService service;@RequestMapping("/findAll")public String findAll(Model model){System.out.println("success");List all = service.findAll();model.addAttribute("user",all);return "list";}
}

添加list.jsp

<%--Created by IntelliJ IDEA.User: AdministratorDate: 2019/10/29Time: 21:07To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>



${user.id}${user.name}${user.gender}${user.email}

实现访问

实现插入

controller

    @RequestMapping("/save")public String save(Model model){System.out.println("success");User u = new User();u.setEmail("184611875@qq.com");u.setGender("男");u.setName("comi");boolean b = service.Save(u);System.out.println(b);return "success";}

UserService

package club.twzw.service;import club.twzw.bean.User;
import org.springframework.stereotype.Service;import java.util.List;public interface UserService {public List findAll();public boolean Save(User u);
}

UserServiceImpl

package club.twzw.service.impl;import club.twzw.bean.User;
import club.twzw.dao.UserDao;
import club.twzw.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;
@Service("UserService")
public class UserServiceImpl implements UserService {@Autowiredprivate UserDao dao;public List findAll() {System.out.println("查询所有用户。。。");return dao.findAll();}@Overridepublic boolean Save(User u) {return dao.Save(u);}
}

dao

package club.twzw.dao;import club.twzw.bean.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;import java.util.List;
@Repository
public interface UserDao {@Select("select * from user")public List findAll();@Insert("insert into user (name,gender,email) values(#{name},#{gender},#{email})")public boolean Save(User u);
}

输出：

 访问路径(http://localhost:8080/ssmWork_war_exploded/save)
这样我们的ssm框架就完成整合了，可以去干大事了！！！！
