SSM框架整合（IntellIj IDEA+Maven+Spring+SpringMVC+MyBatis）之Spring Framework
1.配置SpringMVC
1.1编写Spring配置文件
applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd">
<context:component-scan base-package="com.jyh.controller" >context:component-scan>
<mvc:annotation-driven />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
bean>
beans>1.2编写web.xml配置文件
<web-app 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_3_1.xsd" version="3.1">

1.3编写Controller、jsp & 运行测试
UserController：
/**
* Created by OverrideRe on 2017/7/6.
*/
@Controller
@RequestMapping(value = "/user")
public class UserController {
@RequestMapping(value = "/getUser")
public String getUser(Model model) throws Exception {
User user = new User();
user.setUserName("OverrideRe");
user.setCity("上海");
model.addAttribute("user", user);
return "userInfo";
}
}WEB-INF/jsp/userInfo.jsp
<%--
Created by IntelliJ IDEA.
User: OverrideRe
Date: 2017/7/6
Time: 17:31

运行结果
2.整合SSM
2.1将MyBatis整合进Spring
在applicationContext.xml文件中整合MyBatis配置

beans>2.2编写service、controller
service
/**
* Created by OverrideRe on 2017/7/6.
*/
@Service("userService")
public class UserServiceImpl implements UserService {
@Resource(name = "userMapper")
private UserMapper userMapper;
public void setUserMapper(UserMapper userMapper) {
this.userMapper = userMapper;
}
public UserMapper getUserMapper() {
return userMapper;
}
public User findUserById(String userId){
return userMapper.selectByPrimaryKey(userId);
}
}controller
/**
* Created by OverrideRe on 2017/7/6.
*/
@Controller
@RequestMapping(value = "/user")
public class UserController {
@Resource(name = "userService")
private UserService userService;
@RequestMapping(value = "/getUser")
public String getUser(Model model) throws Exception {
User user = userService.findUserById("111");
model.addAttribute("user", user);
return "userInfo";
}
