一、搭建环境

     1、创建数据库表和表结构

create table account(
id INT identity(1,1) primary key,
name varchar(20),
[money] DECIMAL
)

   2、创建maven的工程SSM，在pom.xml文件引入依赖

 3、部署ssm_web的项目，只要把ssm_web项目加入到tomcat服务器中即可

 4、编写实体类

技术图片技术图片
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 +
                ‘}‘;
    }
}
View Code

 5、编写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 findAll();
}

  6、编写service接口和实现类

package com.mingqi.service;
import com.mingqi.domain.Account;
import java.util.List;
public interface IAccountService {
    public void  saveAccount(Account account);
    public List 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 findAll() {
        System.out.println("业务层：查询所有账户...");
        List accounts=accountDao.findAll();
        return accounts;
        //return null;
    }
}

二、Spring框架代码的编写

    1. 搭建和测试Spring的开发环境

 在webapp项目中创建applicationContext.xml的配置文件，编写具体的配置信息。

技术图片技术图片
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"

    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>
    
    bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        property name="dataSource" ref="dataSource" />
    bean>
    
    bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        property name="basePackage" value="com.mingqi.dao"/>
    bean>
    
    
    bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        property name="dataSource" ref="dataSource" />

    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>

三、Spring整合SpringMVC框架

   1、搭建和测试SpringMVC的开发环境

   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" >

2、测试SpringMVC的框架搭建是否成功

     编写index.jsp和list.jsp编写，超链接

@ page contentType="text/html;charset=UTF-8" language="java" %>
html>
body>
h2>查询所有!h2>
a href="account/findAll">查询所有a>
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>
技术图片技术图片
@ 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>Titletitle>
head>
body>
h3>查询所有的帐户h3>
c:forEach items="${list}" var="account">
    ${account.name}
c:forEach>
body>
html>
View Code

2、创建AccountController类，编写方法，进行测试

技术图片技术图片
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;
    /**
     * 查询所有数据
     * @return
     */

    @RequestMapping("/findAll")
    public String findAll(Model model)
    {

        System.out.println("表现层查询所有");
        accountService.findAll();
        List 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;
    }
}
