1.文件組織結構html

 

  

2.所需jar包：前端

連接：https://share.weiyun.com/51uCJBcjava

 

3.建立數據庫mybatis：mysql

create database mybatis;
use mybatis;
create table t_customer
(
    id       int(32) primary key auto_increment,
    username varchar(50),
    jobs     varchar(50),
    phone    varchar(16)
);
insert into t_customer(username, jobs, phone)
values ('June', 'student', '1862223890*');

3.配置文件web

　　3.1數據庫常量配置文件db.properties：spring

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost/mybatis
jdbc.username=root
jdbc.password=root
jdbc.maxTotal=30
jdbc.maxIdle=10
jdbc.initialSize=5

　　3.2Spring配置文件applicationContext-db.xml：sql

　　首先定義了讀取db.properties文件的配置和數據源配置，而後配置了事務管理器並開啓了事務註解。接下來配置了用於整合MyBatis框架的MyBatis工廠信息，最後定義了mapper掃描器DAO層以及Service層的配置。數據庫

<?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"
       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">
    <context:property-placeholder location="classpath:db.properties"/>
    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxTotal" value="${jdbc.maxTotal}"/>
        <property name="maxIdle" value="${jdbc.maxIdle}"/>
        <property name="initialSize" value="${jdbc.initialSize}"/>
    </bean>
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.sky.dao"/>
    </bean>
    <context:component-scan base-package="com.sky.service"/>
</beans>

　　3.3MyBatis配置文件mybatis-config.xml：apache

　　因爲在Spring中已經配置了數據源信息以及mapper接口文件掃描器，因此在MyBatis的配置文件中只須要根據POJO類路徑進行別名配置便可。瀏覽器

<?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>
    <typeAliases>
        <package name="com.sky.po"/>
    </typeAliases>
</configuration>

3.4Spring配置文件springmvc-config.xml：

　　主要配置了用於掃描@Controller註解的包掃描器、註解驅動器以及視圖解析器。

<?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:mvc="http://www.springframework.org/schema/mvc"
       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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <context:component-scan base-package="com.sky.controller"/>
    <mvc:annotation-driven/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

　　3.5web.xml：

　　配置Spring的文件監聽器、編碼過濾器以及Spring MVC的前端控制等信息。

<?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"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener

        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

4.整合應用測試

　　4.1建立持久化類Customer：com.starrysky.po:Customer.java

package com.sky.po;

public class Customer {
    private Integer id;
    private String username;
    private String jobs;
    private String phone;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getJobs() {
        return jobs;
    }

    public void setJobs(String jobs) {
        this.jobs = jobs;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }
}

　　4.2建立接口文件CustomerDao：com.starrysky.dao:CustomerDao.java

package com.sky.dao;

import com.sky.po.Customer;

public interface CustomerDao {
    public Customer findCustomerById(Integer id);
}

　　4.3根據接口文件的方法編寫執行語句信息：com.starrysky.dao:Customer.xml

<?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.sky.dao.CustomerDao">
    <select id="findCustomerById" parameterType="Integer" resultType="Customer">
        select * from t_customer where id = #{id}
    </select>
</mapper>

　　4.4建立接口文件CustomerService：com.starrysky.service:CustomerService.java

package com.sky.service;

import com.sky.po.Customer;

public interface CustomerService {
    public Customer findCustomerById(Integer id);
}

　　4.5建立CustomerService接口實現類CustomerServiceImpl：com.starrysky.service.impl:CustomerServiceImpl.java

package com.sky.service.impl;

import com.sky.dao.CustomerDao;
import com.sky.po.Customer;
import com.sky.service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class CustomerServiceImpl implements CustomerService {
    @Autowired
    private CustomerDao customerDao;

    @Override
    public Customer findCustomerById(Integer id) {
        return this.customerDao.findCustomerById(id);
    }
}

　　4.6建立用於處理頁面請求的控制器類CustomerController：com.starrysky.controller:CustomerController.java

package com.sky.controller;

import com.sky.po.Customer;
import com.sky.service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class CustomerController {
    @Autowired
    private CustomerService customerService;

    @RequestMapping("/findCustomerById")
    public String findCustomerById(Integer id, Model model) {
        Customer customer = customerService.findCustomerById(id);
        model.addAttribute("customer", customer);
        return "customer";
    }
}

　　4.7建立用於展現客戶詳情的頁面文件：WEB-INF/jsp/customer.jsp

<%--
  Created by IntelliJ IDEA.
  User: Starry-Sky
  Date: 2019/10/9
  Time: 23:33
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>客戶信息</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<table border="1">
    <tr>
        <td>編號</td>
        <td>名稱</td>
        <td>職業</td>
        <td>電話</td>
    </tr>
    <tr>
        <td>${customer.id}</td>
        <td>${customer.username}</td>
        <td>${customer.jobs}</td>
        <td>${customer.phone}</td>
    </tr>
</table>
</body>
</html>

　5.發佈項目到tomcat服務器並啓動，在瀏覽器訪問地址：http://localhost:8080/ssm/findCustomerById?id=1
