三、编写配置文件

3.1、spring配置文件

在src/resources目录下创建spring-config.xml配置文件

    
<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 https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx https://www.springframework.org/schema/tx/spring-tx.xsd">

    
    <context:component-scan base-package="com.zkt.ssm">
        
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>
    
    <context:property-placeholder location="classpath:jdbc.properties"/>

    
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    bean>

    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        
        <property name="configLocation" value="classpath:mybatis.xml"/>
    bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="com.zkt.ssm.mapper"/>
    bean>

    
    
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    bean>
    
    <tx:annotation-driven transaction-manager="transactionManager"/>

beans>

3.2、springMVC配置文件

在src/resources下创建SpringMVC.xml配置文件（视图解析器以thymeleaf测试）

<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 https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
    <context:component-scan base-package="com.zkt.ssm.controller"/>

    
    <bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
        <property name="order" value="1"/>
        <property name="characterEncoding" value="UTF-8"/>
        <property name="templateEngine">
            <bean class="org.thymeleaf.spring5.SpringTemplateEngine">
                <property name="templateResolver">
                    <bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">

                        
                        <property name="prefix" value="/WEB-INF/templates/"/>

                        
                        <property name="suffix" value=".html"/>
                        <property name="templateMode" value="HTML5"/>
                        <property name="characterEncoding" value="UTF-8" />
                    bean>
                property>
            bean>
        property>
    bean>

    
    <mvc:view-controller path="/" view-name="index"/>

    
    <mvc:annotation-driven/>

beans>

3.3、Mybatis映射文件

在src/resouces/下与mapper层相同包的地方创建接口映射文件，如UserMapper.xml

DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zkt.ssm.mapper.UserMapper">
    <update id="addMoney">
        update t_account set money = money - 100 where id = #{id};
    update>
    <update id="deMoney">
        update t_account set money = money + 100 where id = #{id};
    update>
mapper>

3.4、Mybatis核心文件

在src/resouces下创建mybatis.xml核心配置文件

DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    settings>
    <typeAliases>
        <package name="com.zkt.ssm.pojo"/>
    typeAliases>
    <mappers>
        
        <package name="com.zkt.ssm.mapper"/>
    mappers>
configuration>

3.5、数据库连接信息文件

在src/recouces下创建jdbc.properties下创建数据库连接信息文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/userdb
jdbc.username=root
jdbc.password=root

3.6、Web.xml文件

在src下创建webapp目录

之后通过以下操作创建web.xml配置文件

创建完出现在webapp下出现WEB-INF则说明创建成功

<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>contextConfigLocationparam-name>
        <param-value>classpath:spring-config.xmlparam-value>
    context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
    
    <filter>
        <filter-name>CharacterEncodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
        <init-param>
            <param-name>forceResponseEncodingparam-name>
            <param-value>trueparam-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

    <filter>
        <filter-name>HiddenHttpMethodFilterfilter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilterfilter-class>
    filter>
    <filter-mapping>
        <filter-name>HiddenHttpMethodFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

    
    <servlet>
        <servlet-name>springMVCservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        
        <init-param>
            
            <param-name>contextConfigLocationparam-name>
            
            <param-value>classpath:SpringMVC.xmlparam-value>
        init-param>
        
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>springMVCservlet-name>
        
        <url-pattern>/url-pattern>
    servlet-mapping>
web-app>

3.7、log4j.xml文件

在src/resources下创建log4j.xml(名字不可变)日志文件

<configuration status="INFO">
    
    <appenders>
        
        <console name="Console" target="SYSTEM_OUT">
            
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} 【%t】 %-5level %logger{36} - %msg%n"/>
        console>
    appenders>
    
    
    <loggers>
        <root level="info">
            <appender-ref ref="Console"/>
        root>
    loggers>
configuration>

整体创建完如下

四、创建整体架构

4.1、创建controller层

测试如下

@Controller
public class UserController {

    @Autowired
    UserService userService;

    @RequestMapping("/testUser")
    public String testUser(){
        userService.updateMoney();
        return "success";
    }
}

4.2、创建service层

测试如下

service接口

//@Service
public interface UserService {
    public int addMoney(int id);
    public int deMoney(int id);
    public void updateMoney();
}

service实现类

package com.zkt.ssm.service.impl;

import com.zkt.ssm.mapper.UserMapper;
import com.zkt.ssm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author zhangKaiTao
 * @date 2022/4/13 9:31
 */
@Service(value="userService")
//@Transactional()
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;


    public int addMoney(int id) {
        System.out.println("userMapper:"+userMapper);
        return userMapper.addMoney(id);
    }

    public int deMoney(int id) {
        return userMapper.deMoney(id);
    }

    public void updateMoney() {
        userMapper.addMoney(1);
//        int j = 10/0;
        userMapper.deMoney(2);
    }

    public UserMapper getUserMapper() {
        return userMapper;
    }

    public void setUserMapper(UserMapper userMapper) {
        this.userMapper = userMapper;
    }

    @Override
    public String toString() {
        return "UserServiceImpl{" +
                "userMapper=" + userMapper +
                '}';
    }
}

4.3、创建mapper层

测试如下

package com.zkt.ssm.mapper;

/**
 * @author zhangKaiTao
 * @date 2022/4/13 8:47
 */
public interface UserMapper {
    public int addMoney(int id);
    public int deMoney(int id);
}

4.4、创建实体类对象pojo

测试如下

package com.zkt.ssm.pojo;

/**
 * @author zhangKaiTao
 * @date 2022/4/13 8:45
 */
public class User {
    private int id;
    private String name;
    private int money;
}

五、测试

5.1、创建视图

在WEB-INF下创建包templates

创建index.html

DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<body>
<h1>首页h1>
<a th:href="@{/testUser}">测试转账a>
body>
html>

创建success.html

DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<body>
<h1>successh1>
body>
html>

5.2、创建数据库

CREATE TABLE `t_account` (
  `id` int(20) NOT NULL,
  `username` varchar(255) DEFAULT NULL,
  `money` int(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

5.3、配置tomcat并发布

5.4、测试结果

启动服务，开启tomcat

启动之后

点击测试转账之后

数据库变化
