Spring Boot Web框架：智慧社区设计新思路概念模式的设计方法是在需求分析的基础上，用概念数据模型（例如E-R模型）表示数据及数据之间的相互联系，设计出反映用户信息需求和处理需求的数据库系统概念模式。概念设计的目标是准确描述应用领域的信息模式，支持用户的各种应用，这样既容易转换为数据库系统逻辑模式，又容易为用户理解。在概念模式的设计中，E-R模型法是最常见的设计方法。概念设计的目标是设计出反映某个组织部门信息需求的数据库系统概念模式，数据库系统的概念模式独立于数据库系统的逻辑结构、独立于数据库管理系统（DBMS）、独立于计算机系统。阅读详情

第一步:
导入ssm框架所需坐标比如spring,springmvc,mybatis

首先来配置一下spring和springmvc的配置文件
spring的配置文件: 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: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
">
<!--        配置组件扫描-->
    <context:component-scan base-package="com.zking">
<!--        排除controller的扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

<!--    加载properties-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
<!--    配置数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property  name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
<!--    配置mybatis的sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
<!--        加载mybatis核心文件-->
        <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
    </bean>

<!--    配置扫描mapper所在的包  为mapper创建实现类 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.zking.mapper"></property>
    </bean>
<!--    声明式事务控制-->
<!--    配置平台事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

<!--    配置事务增强-->
    <tx:advice id="txAdvice">
        <tx:attributes>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>

<!--    事务aop的织入-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.zking.service.impl.*.*(..))"></aop:advisor>
    </aop:config>
</beans>

springmvc的配置文件:

<?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:mvc="http://www.springframework.org/schema/mvc"
       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/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
">
<!--    配置组件扫描-->
    <context:component-scan base-package="com.zking.controller"/>
<!--    配置mvc注解驱动-->
    <mvc:annotation-driven/>
<!--    配置内部资源视图扫描器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="suffix" value=".jsp"/>
        <property name="prefix" value="/"/>
    </bean>
<!--    配置静态资源访问器-->
    <mvc:default-servlet-handler/>
</beans>

下面就是mybatis的配置文件了
这是核心配置文件:我这里用spring整合了mybatis所以配置文件中不用写什么代码

<?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>
<!--    定义别名-->
    <typeAliases>
        <typeAlias type="com.zking.domain.Account" alias="account"></typeAlias>
    </typeAliases>
</configuration>

这是mybatis的映射文件它也可以省略,它可以使用注解代替

<?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.zking.mapper.AccountMapper">
    <select id="findAll" resultType="account">
        select * from account
    </select>
    <insert id="save" parameterType="account">
        insert into account values(#{id},#{name},#{money})
    </insert>
</mapper>

下面就是实体类了:

public class Account implements Serializable {
    private Integer id;
    private String name;
    private String money;
    //由于set和get代码太多而且大家都知道所以我就不写了

业务层代码:

public interface AccountService {
    /**
     * 保存账户数据
     * @param account
     */
    void save(Account account) throws IOException;

    /**
     * 查询账户数据
     * @return
     */
    List<Account> findAll() throws IOException;
}

业务层实现:

@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Autowired
    private AccountMapper accountMapper;
    @Override
    public void save(Account account) {
        accountMapper.save(account);
    }

    @Override
    public List<Account> findAll() {
        return accountMapper.findAll();
    }
}

mapper层代码:

public interface AccountMapper {

    void save(Account account);

    List<Account> findAll();
}

controller层代码:

@Controller
@RequestMapping("/account")
public class AccountController {
    @Autowired
    private AccountService accountService;
//    保存
    @RequestMapping(value = "/save",produces = "text/html;charset=UTF-8")
    @ResponseBody
    public String save(Account account) {
       accountService.save(account);
        return "保存成功";
    }
    //查询功能
    @RequestMapping("/findAll")
    public ModelAndView findAll(){
        List<Account> accounts=null;
        ModelAndView modelAndView=new ModelAndView();
        accounts = accountService.findAll();
        modelAndView.addObject("accounts",accounts);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}

还有最后两个前端页面代码:
绑定数据的:我这里写的就是一个简单的表格,因为时间的原因就没用js了直接使用的c标签

<html>
<head>
    <title>Title</title>
</head>
<body style="text-align:center;">
<h1>展示账户数据</h1>
<table border="1" content="auto" align="center">
    <thead>
    <tr>
        <td>编号</td>
        <td>姓名</td>
        <td>金额</td>
    </tr>
    </thead>
    <tbody>
    <c:forEach items="${accounts}" var="a">
    <tr>
        <td>${a.id}</td>
        <td>${a.name}</td>
        <td>${a.money}</td>
    </tr>
    </c:forEach>
    </tbody>
</table>
</body>
</html>

下面就是一个简单的增加页面

<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>添加账户信息表单</h1>
<form name="accountForm" action="${pageContext.request.contextPath}/account/save" method="post">
    账户名称:<input type="text" name="name"><br/>
    账户金额:<input type="text" name="money"><br/>
    <input type="submit" value="保存"><br/>
</form>
</body>
</html>

差点忘记了最后一个文件
web.xml

<?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"

         version="3.1">
