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;
@Override
public 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<user> 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<User> findAll();
}
4.实现userServiceImpl,并给userServiceImpl 起别名userService
@Service("userService")
public class userServiceImpl implements userService {
@Override
public List<user> 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
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-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/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<!--只处理Service和dao -->
<context:component-scan base-package="club.twzw">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
</beans>
6.书写测试方法
@Test
public 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class
service.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
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<servlet>
<servlet-name>spring-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--加载springmvc.xml配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!--启动服务器时，创建该servlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置中文乱码过滤器-->
<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>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
</web-app>
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
<?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/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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--开启注解扫描，只扫描controller-->
<context:component-scan base-package="club.twzw">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--配置视图解析器-->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="suffix" value=".jsp"/>
<property name="prefix" value="/WEB-INF/views/"/>
</bean>
<!--过滤静态资源-->
<!-- <mvc:resources mapping="/css/**" location="/css/"/>-->
<!-- <mvc:resources mapping="/images/**" location="/images/"/>-->
<!-- <mvc:resources mapping="/js/**" location="/js/"/>-->
<!--开启springmvc注解支持-->
<mvc:annotation-driven/>
</beans>
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 {
@Autowired
private UserService service;
@RequestMapping("/findAll")
public String findAll(Model model){
System.out.println("success");
List<User> all = service.findAll();
model.addAttribute("user",all);
return "list";
}
}
index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<body>
<a href="/findAll">查看所有用户</a>
</body>
</html>
success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>scuccess</title>
</head>
<body>
<h1>scuccess</h1>
</body>
</html>
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
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<!--加载Spring-->
<!--配置监听器,默认只加载web-inf目录下的applicationContext.xml-->
<!--但是我们的文件在resources文件夹下--> <<<<------
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件路径--> <<<<------
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--加载spring mvc-->
<!--配置前端控制器-->
<servlet>
<servlet-name>spring-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--加载springmvc.xml配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!--启动服务器时，创建该servlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置中文乱码过滤器-->
<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>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
</web-app>
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 {
@Autowired
private 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<User> findAll();
}
创建mybatis的核心配置文件mysqlConfig.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org.//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<!-- mybatis 的 主配置文件-->
<configuration>
<environments default="mysql">
<!--配置mysql-->
<environment id="mysql">
<!--配置事务类型-->
<transactionManager type="JDBC"/>
<!--配置数据源/连接池-->
<dataSource type="POOLED">
<!--配置连接数据库的基本信息-->
<property name="driver" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://xx.xx.xx:3306/learn?useSSL=false"/>
<property name="username" value="learn"/>
<property name="password" value="123456"/>
</dataSource>
</environment>
</environments>
<!--指定映射配置文件的位置，映射配置文件指的是每个dao独立的配置文件-->
<mappers>
<!--使用xml进行查询-->
<!--<mapper resource="mapper/UserDao.xml"/>-->
<!--使用注解-->
<!--<mapper class="club.twzw.dao.UserDao"/>-->
<!--扫描mapper下所有注解-->
<package name="mapper"/>
</mappers>
</configuration>
书写测试方法
@Test
public 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<User> 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！
<?xml version="1.0" encoding="UTF-8"?>

</bean>
<!--配置dao所在的包-->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="club.twzw.dao"/>
</bean>
</beans>
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<User> 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 {
@Autowired
private UserDao dao;
public List<User> 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 {
@Autowired
private UserService service;
@RequestMapping("/findAll")
public String findAll(Model model){
System.out.println("success");
List<User> all = service.findAll();
model.addAttribute("user",all);
return "list";
}
}
添加list.jsp

public String save(Model model){
System.out.println("success");
User u = new User();
u.setEmail("184611875@qq.com");

这样我们的ssm框架就完成整合了，可以去干大事了！！！！
