SSM中的模板

前言

Spring SpringMVC Mybatis：

在使用SSM时，我们常常会用到很多模板，这篇文章便来记录这些常用的模板。

以下是本篇文章正文内容，下面模板可供参考

一、pom.xml

maven项目中的pom.xml模板分别做了：集中定义版本编号、配置多种依赖、插件配置、识别所有文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

二、jdbc.properties

jdbc.properties文件放在resources文件夹中

位置src / main / java / resources / jdbc.properties

注意：jdbc.properties存放的是连接池用到的值，我这里的值用于连接MySQL8.0
（MySQL8.0以上和MySQL5.x在连接配置上有差别，请自行上网了解）

jdbc.driverClassName=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmuser?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true
jdbc.username=root
jdbc.password=root

三、SqlMapConfig.xml

MyBatis要用的配置文件，放到resources文件夹中

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>

configuration>

四、applicationContext_mapper.xml

resources文件夹

<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"
       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">

    
    <context:property-placeholder location="classpath:jdbc.properties"/>

    
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    bean>

    
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        
        <property name="dataSource" ref="dataSource"/>
        
        <property name="configLocation" value="classpath:SqlMapConfig.xml"/>
        
        <property name="typeAliasesPackage" value="包路径.pojo包"/>
    bean>

    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="包路径.mapper包"/>
    bean>
beans>

总结

ssm项目需要用到的配置文件比较多，总会有遗漏的地方，这时通过模板来补遗，是个很不错的选择。

此处为笔记（上），下期的笔记（下）包含三个：

• applicationContext_service.xml
• springmvc.xml
• web.xml
