SSM——Spring整合SpringMVC,MyBatis
一、環境搭建
1.建立資料庫 account賬戶表
2.建立Maven web工程
3.匯入座標並建立依賴

4.編寫log4j.properties配置檔案
# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE debug info warn error fatal
log4j.rootCategory=info, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
5.編寫實體類
package com.beizhen.domain;
import java.io.Serializable;
/**
* 賬戶實體類
* @author : Bei-Zhen
* @date : 2020-11-21 18:37
*/
public class Account implements Serializable {
private Integer id;
private String name;
private Double money;
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 Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\'' +
", money=" + money +
'}';
}
}
6.編寫持久化層
package com.beizhen.dao;
import com.beizhen.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* 賬戶的持久化層介面
* @author : Bei-Zhen
* @date : 2020-11-21 18:39
*/
@Repository
public interface IAccountDao {
/**
* 查詢所有賬戶
* @return
*/
@Select("select * from account")
List<Account> findAll();
/**
* 儲存賬戶資訊
* @param account
*/
@Insert("insert into account (name,money) values (#{name},#{money})")
void saveAccount(Account account);
}
7.編寫業務層
package com.beizhen.service;
import com.beizhen.domain.Account;
import java.util.List;
/**
* 賬戶的業務層介面
* @author : Bei-Zhen
* @date : 2020-11-21 18:42
*/
public interface IAccountService {
/**
* 查詢所有賬戶
* @return
*/
List<Account> findAll();
/**
* 儲存賬戶資訊
* @param account
*/
void saveAccount(Account account);
}
package com.beizhen.service.impl;
import com.beizhen.dao.IAccountDao;
import com.beizhen.domain.Account;
import com.beizhen.service.IAccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* 賬戶的業務層實現類
* @author : Bei-Zhen
* @date : 2020-11-21 18:43
*/
@Service("accountService")
public class AccountServiceImpl implements IAccountService {
@Autowired
private IAccountDao accountDao;
/**
* 查詢所有賬戶
* @return
*/
@Override
public List<Account> findAll() {
System.out.println("業務層:查詢所有賬戶...");
return accountDao.findAll();
}
/**
* 儲存賬戶資訊
* @param account
*/
@Override
public void saveAccount(Account account) {
System.out.println("業務層:儲存賬戶...");
accountDao.saveAccount(account);
}
}
二、編寫spring框架
1.編寫spring主配置檔案: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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 開啟註解的掃描,只處理service和dao-->
<context:component-scan base-package="com.beizhen">
<!-- 配置哪些註解不掃描-->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--Spring整合MyBatis框架-->
<!--配置連線池-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql:///ssm"/>
<property name="user" value="root"/>
<property name="password" value="root"/>
</bean>
<!--配置SqlSessionFactory工廠-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean>
<!--配置IAccountDao介面所在包-->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.beizhen.dao"/>
</bean>
<!--配置Spring框架宣告式事務管理-->
<!--配置事務管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!--配置事務通知-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" read-only="true"/>
<tx:method name="*" isolation="DEFAULT"/>
</tx:attributes>
</tx:advice>
<!--配置AOP增強-->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.beizhen.service.impl.*ServiceImpl.*(..))"/>
</aop:config>
</beans>
2.使用註解配置業務層和持久層
3.測試spring層是否單獨執行成功
三、編寫spring框架
1.配置web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<!--配置Spring的監聽器,預設只載入WEB-INF目錄下的applicationContext.xml配置檔案-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--設定配置檔案的路徑-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<context-param>
<param-name/>
<param-value/>
</context-param>
<context-param>
<param-name/>
<param-value/>
</context-param>
<!--配置前端控制器-->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--載入springmvc.xml配置檔案-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!--啟動伺服器,建立該servlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--解決中文亂碼的過濾器-->
<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>
2.編寫 SpringMVC 的配置檔案
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
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">
<!--開啟註解掃描,只掃描Controller註解-->
<context:component-scan base-package="com.beizhen">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<!--配置的檢視解析器物件-->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!--過濾靜態資源-->
<mvc:resources location="/css/" mapping="/css/**" />
<mvc:resources location="/images/" mapping="/images/**" />
<mvc:resources location="/js/" mapping="/js/**" />
<!--開啟SpringMVC註解的支援-->
<mvc:annotation-driven/>
</beans>
3.編寫 Controller 和 jsp 頁面
package com.beizhen.controller;
import com.beizhen.domain.Account;
import com.beizhen.service.impl.AccountServiceImpl;
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 javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;
/**
* 賬戶web層
* @author : Bei-Zhen
* @date : 2020-11-21 18:51
*/
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountServiceImpl accountService;
@RequestMapping("/findAll")
private String findAll(Model model){
System.out.println("表現層:查詢所有賬戶...");
// 呼叫service的方法
List<Account> list = accountService.findAll();
model.addAttribute("list",list);
return "list";
}
/**
* 儲存
* @return
*/
@RequestMapping("/save")
public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
accountService.saveAccount(account);
response.sendRedirect(request.getContextPath()+"/account/findAll");
return;
}
}
index.jsp

4.測試spring層是否單獨執行成功
5.整合 Spring 和 SpringMVC
四、編寫MyBatis框架
1.編寫 SqlMapConfig 主配置檔案
<?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">
<configuration>
<!-- 配置properties-->
<properties resource="jdbcConfig.properties">
</properties>
<!-- 配置domain中類的別名,別名不區分大小寫-->
<typeAliases>
<package name="com.beizhen.domain"/>
</typeAliases>
<!-- 配置環境-->
<environments default="mysql">
<!-- 配置mysql的環境-->
<environment id="mysql">
<!-- 配置事務-->
<transactionManager type="JDBC"></transactionManager>
<!-- 配置連線池-->
<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</dataSource>
</environment>
</environments>
<!-- 配置對映檔案的位置-->
<mappers>
<!-- 用於指定dao介面所在的包-->
<package name="com.beizhen.dao"/>
</mappers>
</configuration>
2.編寫jdbcConfig.properties資料庫配置檔案
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm
jdbc.username=root
jdbc.password=root
3.使用註解配置dao層的類
4.測試spring層是否單獨執行成功
5.整合 Spring 和 MyBatis
五、測試ssm是否整合成功
如圖所示,已經執行成功了!!!
