项目整体布局
- 整合说明:SSM整合可以使用多种方式,咱们会选择XML + 注解的方式
- 整合的思路
先搭建整合的环境
先把Spring的配置搭建完成
再使用Spring整合SpringMVC框架
最后使用Spring整合MyBatis框架
说明
因为 Spring MVC 是 Spring 框架中的一个子模块,所以 Spring 与 SpringMVC 之间不存在整合的问题。实际上,SSM 框架的整合只涉及 Spring 与 MyBatis 的整合以及 Spring MVC 与 MyBatis 的整合。
1.创建数据库和表结构
create database ssm; use ssm; create table account( id int primary key auto_increment, name varchar(20), money double );
web依赖于service,service依赖于dao,dao依赖于domain
2.pom.xml文件中引入坐标依赖

3.在domain中编写实体类
package com.domain; import java.io.Serializable; /** * 帐户 */ 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 + '}'; } }
4.编写dao接口
package com.dao; import com.domain.Account; import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.Select; import org.springframework.stereotype.Repository; import java.util.List; /** * 帐户dao接口 */ @Repository public interface AccountDao { // 查询所有账户 @Select("select * from account") public List<Account> findAll(); // 保存帐户信息 @Insert("insert into account (name,money) values (#{name},#{money})") public void saveAccount(Account account); }
5.编写service接口和实现类
package com.service; import com.domain.Account; import java.util.List; public interface AccountService { // 查询所有账户 public List<Account> findAll(); // 保存帐户信息 public void saveAccount(Account account); }
package com.service.impl; import com.dao.AccountDao; import com.domain.Account; import com.service.AccountService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service("accountService") public class AccountServiceImpl implements AccountService { @Autowired private AccountDao accountDao; public List<Account> findAll() { System.out.println("业务层:查询所有账户..."); return accountDao.findAll(); } public void saveAccount(Account account) { System.out.println("业务层:保存帐户..."); accountDao.saveAccount(account); } }
6.编写Controller 层创建AccountController类,编写方法
package com.controller; import com.domain.Account; import com.service.AccountService; 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; /** * 帐户web 控制器 */ @Controller @RequestMapping("/account") public class AccountController { // 自动类型注入 @Autowired private AccountService accountService; @RequestMapping("/findAll") public String findAll(Model model){ System.out.println("表现层:查询所有账户..."); // 调用service的方法 整合spring List<Account> list = accountService.findAll(); model.addAttribute("list",list); return "list"; } /** * 保存 * @return */ @RequestMapping("/save") public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException { accountService.saveAccount(account); response.sendRedirect(request.getContextPath()+"/account/findAll"); return; } }
7.编写index.jsp和list.jsp编写
index.jsp
<%-- Created by IntelliJ IDEA. User: Administrator Date: 2018/5/6 Time: 0:22 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> <a href="account/findAll">测试查询</a> <h3>测试包</h3> <form action="account/save" method="post"> 姓名:<input type="text" name="name" /><br/> 金额:<input type="text" name="money" /><br/> <input type="submit" value="保存"/><br/> </form> </body> </html>
list.jsp
<%-- Created by IntelliJ IDEA. User: Administrator Date: 2018/5/6 Time: 0:24 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <head> <title>Title</title> </head> <body> <h3>查询所有的帐户</h3> <c:forEach items="${list}" var="account"> ${account.name} </c:forEach> </body> </html>
8.创建相关配置文件在web.xml中配置springmvc相关的
在 WEB-INF 目录下创建 web.xml 文件,并在该文件中实例化 ApplicationContext 容器、启动 Spring 容器、配置 DispatcherServlet 以及配置字符编码过滤器。具体代码如下:
<!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的监听器,默认只加载WEB-INF目录下的applicationContext.xml配置文件--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--设置配置文件的路径 加载spring的配置文件--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</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> <!--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,创建该servlet--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--解决中文乱码的过滤器--> <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>
9.创建springmvc.xml的配置文件,编写配置文件
在 WEB-INF 目录下创建 Spring MVC 的核心配置文件 springmvc.xml,在该文件中仅配置控制器扫描包和视图解析器
<?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"> <!--开启注解扫描,只扫描Controller注解--> <context:component-scan base-package="com"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!--配置的视图解析器对象--> <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"/> <property name="suffix" value=".jsp"/> </bean>## 标题 <!--过滤静态资源--> <mvc:resources location="/css/" mapping="/css/**" /> <mvc:resources location="/images/" mapping="/images/**" /> <mvc:resources location="/js/" mapping="/js/**" /> <!--开启SpringMVC注解的支持--> <mvc:annotation-driven/> </beans>
10.创建applicationContext.xml的配置文件,编写具体的配置信息
<?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/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/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--spring的配置文件--> <!--开启注解的扫描,希望处理service和dao,controller不需要Spring框架去处理--> <context:component-scan base-package="com" > <!--配置哪些注解不扫描--> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!--Spring整合MyBatis框架--> <!--配置连接池--> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"/> <property name="user" value="root"/> <property name="password" value="root"/> </bean> <!--配置SqlSessionFactory工厂--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean> <!--配置AccountDao接口所在包--> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.dao"/> </bean> <!--配置Spring框架声明式事务管理--> <!--配置事务管理器--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!--配置事务通知--> <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增强--> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.service.impl.*ServiceImpl.*(..))"/> </aop:config> </beans>
11.加log4j.properties,日志文件
# 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
12.测试结果
