一.SSM框架整合
需求：使用ssm框架完成對account表的增刪改查操作。
（1）搭建Mybatis環境：
1.確定數據庫 和表
CREATE DATABASE /*!32312 IF NOT EXISTS*/`spring_db` /*!40100 DEFAULT CHARACTER SET utf8 */;
USE `spring_db`;
/*Table structure for table `account` */
DROP TABLE IF EXISTS `account`;
CREATE TABLE `account` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(32) DEFAULT NULL,
`money` double DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
/*Data for the table `account` */
insert into `account`(`id`,`name`,`money`) values (1,'tom',1000),(2,'jerry',1000);
2.創建web模塊，導入相關座標：
<!--依賴管理-->
<dependencies>
<!--mybatis相關座標-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.47</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.15</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.5.1</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.10</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
</dependencies>
Account實體
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Account {
private Integer id;
private String name;
private Double money;
}
AccountDao接口和映射
public interface AccountDao {
public List<Account> findAll();
}
同時在resources資源裏面創建mybaits相關的AccountDao.xml文件
<?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.wsl.dao.AccountDao">
<select id="findAll" resultType="com.wsl.domain.Account">
select * from account
</select>
</mapper>
SqlMapConfig.xml配置
<?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>
<!--加載properties屬性文件-->
<properties resource="jdbc.properties"></properties>
<!--設置java類型別名-->
<typeAliases>
<package name="com.wsl.domain"></package>
</typeAliases>
<!--環境配置-->
<environments default="mysql">
<!--mysql環境-->
<environment id="mysql">
<!--使用JDBC類型事務管理器 -->
<transactionManager type="JDBC"></transactionManager>
<!--使用連接池 POOLED-->
<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</dataSource>
</environment>
</environments>
<!--加載映射文件-->
<mappers>
<package name="com.wsl.dao"></package>
</mappers>
</configuration>
測試：
public class MyBatisTest {
@Test
public void test01() throws Exception {
// 1.加載核心配置文件
InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
// 2.構建工廠對象
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(in);
// 3.創建會話對象
SqlSession sqlSession = sqlSessionFactory.openSession();
// 4.創建代理對象
AccountDao accountDao = sqlSession.getMapper(AccountDao.class);
// 5.查詢
List<Account> list = accountDao.findAll();
for (Account account : list) {
System.out.println(account);
}
// 6.釋放資源
sqlSession.close();
}
}
此時搭建MyBatis環境完畢
（2）搭建spring環境
1.導入spring座標
<!--spring相關座標-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.1.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.9.5</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.1.5.RELEASE</version>
</dependency>
2.AccountService接口和實現
public interface AccountService {
List<Account> findAll();
}
@Service
public class AccountServiceImpl implements AccountService {
@Override
public List<Account> findAll() {
System.out.println("AccountServiceImpl執行了...");
return null;
}
}
3.applicationContext.xml配置
<?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:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
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/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">
<!--開啓註解組件掃描-->
<context:component-scan base-package="com.wsl.service"/>
</beans>
測試：
@RunWith(SpringRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SpringTest {
@Autowired
private AccountService accountService;
@Test
public void test01()throws Exception{
List<Account> list = accountService.findAll();
}
}
（3）spring整合MyBatis環境
思想：
原來我們使用mybatis框架，需要手動創建 sqlSessionFactory 、 sqlSession 、accountDao代理對象，被spring整合後，這些對象的創建權都交給ioc容器，我們的service層就可以直接使用@Autowired 完成依賴注入，整合就搞定了
MyBatis分析：
整合：
1.導入整合座標：
<!--spring整合mybatis座標-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.2</version>
</dependency>
<?xml version="1.0" encoding="UTF-8"?>

</bean>
<!--配置SqlSessionFactoryBean-->
<bean id="sessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定連接池 -->

<!-- 指定實體類型別名 -->
<property name="typeAliasesPackage" value="com.wsl.domain"/>
<!-- 加載mybatis的核心配置文件,如果mybatis核心配置空了，這一步可以省略....-->
<property name="configLocation" value="classpath:SqlMapConfig.xml"/>
</bean>
<!--配置dao層接口代理對象掃描-->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.wsl.dao"/>
</bean>
</beans>
修改AccountService實現
@Service
public class AccountServiceImpl implements AccountService {
// 依賴AccountDao
@Autowired
private AccountDao accountDao;
@Override
public List<Account> findAll() {
return accountDao.findAll();
}
}
測試：
@RunWith(SpringRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SpringTest {
@Autowired
private AccountService accountService;
@Test
public void test01()throws Exception{
List<Account> list = accountService.findAll();
for (Account account : list) {
System.out.println(account);
}
}
}
測試通過：
總結：
（4）搭建SpringMVC環境
導入springMVC座標
<!--springMVC座標-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.5.RELEASE</version>
</dependency>

<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
導入相關頁面資源：
web.xml
前端控制器，中文過濾器
<?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"

</beans>
AccountController和list.jsp頁面
@RequestMapping(value = "/account", name = "賬戶模塊")
public class AccountController {
@RequestMapping(value = "/findAll", name = "查詢賬戶列表")
public String findAll(Model model) {
// 模擬service，提供假數據...
List<Account> list = new ArrayList<>();
list.add(new Account(1, "jack", 200d));
list.add(new Account(2, "lucy", 100d));
list.add(new Account(3, "lufei", 200d));
list.add(new Account(4, "james", 3000d));
model.addAttribute("list", list);
return "/list.jsp"; // 使用默認視圖解析器
}
}
訪問測試：在index.jsp配置：
然後進行tomcat部署即可測試成功
（5）Spring整合（web容器）
思想：
springMVC和spring本身就是同一家公司，不需要編寫任何整合代碼，可以做到無縫對接....
雖然不需要寫任何整合代碼，但是web.xml 只加載了（DispatcherServlet）前端控制器，掃描了 spring-mvc.xml配置文件，並沒有去加載 applicationContext.xml配置文件，所以web層無法依賴注入service層代碼...
我們現在需要在web項目啓動時，加載spring環境，那麼springMVC就可以從spring容器獲得service對象了...
我們這裏需要藉助一個監聽器：ServletContextListener，就可以在web工程啓動時，加載spring的環境 applicationContext.xml,初始化spring容器，至此我們的web層就可以注入service層代碼了...
spring框架就提供了這個一個監聽器，專門加載applicationContext.xml,配置文件... 這裏需要導入一個座標
spring-web，springMVC的座標其實已經包含了它
在web.xml中配置監聽器：
<!--配置監聽器，加載Spring環境-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
修改AccountController
@Controller
@RequestMapping(value = "/account", name = "賬戶模塊")
public class AccountController {
// 依賴AccountService
@Autowired
private AccountService accountService;
@RequestMapping(value = "/findAll", name = "查詢賬戶列表")
public String findAll(Model model) {
List<Account> list = accountService.findAll();
model.addAttribute("list", list);
return "/list.jsp"; // 使用默認視圖解析器
}
}
自此，三大框架整合成功了
（6）賬戶新增：
add.jsp修改
web層
@RequestMapping(value = "/save",name = "添加賬戶")
public String save(Account account){
accountService.save(account);
return "redirect:/account/findAll.do";
}
service層
dao層：
測試完成即可
（7）聲明式事務
方式一：註解方式
applicationContext.xml文件
AccountService實現
（2）xml方式：
<!--配置事務管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="serviceOperation" expression="execution(* com.wsl.service..*.*(..))"></aop:pointcut>
<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"></aop:advisor>
</aop:config>
（8）賬戶修改:
list.jsp
web層：
service層：
dao層“
Account findById(Integer id);
<select id="findById" resultType="com.wsl.domain.Account">
select * from account where id=#{id}
</select>
update.jsp
修改數據：
update.jsp
web層
service層
dao層
void update(Account account);
一般sql執行方案：
update account set name=#{name},money=#{money} where id=#{id}
動態sql執行方案：
<update id="update">
update account
<set>
<if test="name !=null">
name=#{name},
</if>
<if test="money !=null">
money=#{money},
</if>
</set>
where id=#{id}
</update>
執行完畢即可成功
（9）刪除賬戶：
list.jsp
AccountController
@RequestMapping(value = "/delete",name = "賬戶刪除")
public String delete(Integer id){
accountService.delete(id);
return "redirect:/account/findAll.do";
}
service
@Override
public void delete(Integer id) {
accountDao.delete(id);
}
dao層
void delete(Integer id);
<delete id="delete">
delete from account where id=#{id}
</delete>
執行完畢即可
（10）批量刪除：
全選與反選：
運行流程：
web層：
service層
dao層：
測試完成成功。
二.用戶登錄權限控制：
在企業開發中，有的頁面需要進行權限控制。
思想：
（1）用戶登錄
準備user表與數據：
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(32) NOT NULL,
`password` varchar(32) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
insert into `user`(`id`,`username`,`password`) values (1,'jack','123'),(2,'tom','123');
User實體：
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {
private Integer id;
private String username;
private String password;
}
login.jsp
web層
@Controller
@RequestMapping(value = "/user", name = "用戶模塊")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value = "/login", name = "登錄功能")
public String login(User user, HttpServletRequest request, HttpSession session) {
User currentUser = userService.login(user);
if (currentUser == null) { // 登錄失敗
request.setAttribute("error", "用戶名或密碼錯誤...");
return "/login.jsp";
}
// 登錄成功，跳轉到查詢列表頁面
session.setAttribute("currentUser", currentUser);
return "redirect:/account/findAll.do";
}
}
service層
dao層
login.jsp:顯示錯誤信息
（2）權限攔截：
自定義登錄攔截器
/*
登錄攔截器
*/
public class LoginInterceptor implements HandlerInterceptor {
// 預處理攔截
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
// 1.從session中獲取登錄user對象
User currentUser = (User) request.getSession().getAttribute("currentUser");
// 2.判斷
if(currentUser == null){
try {
// 重定向到登錄頁面
response.sendRedirect(request.getContextPath()+"/login.jsp");
} catch (IOException e) {
e.printStackTrace();
}
// 未登錄，攔截
return false;
}
// 已登錄放行
return true;
}
}
在spring-mvc.xml中配置攔截器規則
<!--配置登錄攔截器規則-->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/account/*"/>
<bean class="com.wsl.web.interceptor.LoginInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>
三.Spring父子容器；
我們使用的spring框架，通過ContextLoaderListener加載的spring容器（父容器）
我們使用的springMVC框架，通過DispatcherServlet加載springMVC容器（子容器）
四，總結
ssm配置的總結項：
