一、搭建環境
1、創建數據庫表和表結構
create table account(
id INT identity(1,1) primary key,
name varchar(20),
[money] DECIMAL
2、創建maven的工程SSM，在pom.xml文件引入依賴
<?xml version="1.0" encoding="UTF-8"?>

3、部署ssm_web的項目，只要把ssm_web項目加入到Tomcat服務器中即可
4、編寫實體類
package com.mingqi.domain;
import java.io.Serializable;
public class Account implements Serializable {
public void setId(Integer id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public void setMoney(Double money) {
this.money = money;
}
public Integer getId() {
return id;
}
public String getName() {
return name;
}
public Double getMoney() {
return money;
}
private Integer id;
private String name;
private Double money;
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + ''' +
", money=" + money +
'}';
}
}
5、編寫dao接口
package com.mingqi.dao;
import com.mingqi.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface IAccountDao {
@Insert(value="insert into account (name,money) values (#{name},#{money})")
public void saveAccount(Account account);
@Select("select * from account")
public List<Account> findAll();
}
6、編寫service接口和實現類
package com.mingqi.service;
import com.mingqi.domain.Account;
import java.util.List;
public interface IAccountService {
public void saveAccount(Account account);
public List<Account> findAll();
}
package com.mingqi.service.impl;
import com.mingqi.dao.IAccountDao;
import com.mingqi.domain.Account;
import com.mingqi.service.IAccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountImpl implements IAccountService {
@Autowired
private IAccountDao accountDao;
@Override
public void saveAccount(Account account) {
accountDao.saveAccount(account);
}
@Override
public List<Account> findAll() {
System.out.println("業務層：查詢所有賬戶...");
List<Account> accounts=accountDao.findAll();
return accounts;
//return null;
}
}
二、Spring框架代碼的編寫
1. 搭建和測試Spring的開發環境
在webapp項目中創建applicationContext.xml的配置文件，編寫具體的配置信息。
<?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">
<!-- 開啟注解掃描，要掃描的是service和dao層的注解，要忽略web層注解，因為web層讓SpringMVC框架
去管理 -->
<context:component-scan base-package="com.mingqi">
<!-- 配置要忽略的注解 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 配置C3P0的連接池對象 -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/>
<property name="url" value="jdbc:sqlserver://localhost:1433;DatabaseName=test"/>
<property name="username" value="sa"/>
<property name="password" value="123sa"/>
</bean>
<!-- 配置SqlSession的工廠 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 配置掃描dao的包 -->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.mingqi.dao"/>
</bean>
<!--配置Spring框架聲明式事務管理-->
<!--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>
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(public * com.mingqi.service..ServiceImpl.*(..))"/>
</aop:config>
</beans>
三、Spring整合SpringMVC框架
1、搭建和測試SpringMVC的開發環境
1. 在web.xml中配置DispatcherServlet前端控制器
<!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，默認只加載WEB-INF目錄下的applicationContext.xml配置文件-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--設置配置文件的路徑-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<context-param>
<param-name/>
<param-value/>
</context-param>
<!--配置前端控制器-->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--加載springmvc.xml配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!--啟動服務器，創建該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、測試SpringMVC的框架搭建是否成功
1. 編寫index.jsp和list.jsp編寫，超鏈接
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<body>
<h2>查詢所有!</h2>
<a href="account/findAll">查詢所有</a>
<a href="account/findAll">測試查詢</a>
<h3>測試包</h3>
<form action="account/save" method="post">
姓名：<input type="text" name="name" /><br/>
金額：<input type="text" name="money" /><br/>
<input type="submit" value="保存"/><br/>
</form>
</body>
</html>
<%@ 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>查詢所有的帳戶</h3>
<c:forEach items="${list}" var="account">
${account.name}
</c:forEach>
</body>
</html>
2、創建AccountController類，編寫方法，進行測試
package com.mingqi.controller;
import com.mingqi.domain.Account;
import com.mingqi.service.IAccountService;
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;
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private IAccountService accountService;
/**
* 查詢所有數據
* @return
*/
@RequestMapping("/findAll")
public String findAll(Model model)
{
System.out.println("表現層查詢所有");
accountService.findAll();
List<Account> list = accountService.findAll();
model.addAttribute("list",list);
return "list";
}
@RequestMapping("/save")
public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException
{
accountService.saveAccount(account);
response.sendRedirect(request.getContextPath()+"/account/findAll");
return;
}
}
配置tomcat，啟動項目，進行測試
