SSMp项目的环境搭建

　　Spring+SpringMVC+MybatisPlus 项目的环境搭建如下：

1、pom.xml文件

　　导入相关依赖：spring、servlet、jsp、jstl、mybatis-plus、mysql、连接池以及junit4

            <scope>compile</scope>
        </dependency>
        
    </dependencies>

2、/ webapp / WEB-INF / web.xml 文件

　　web项目启动时首先加载该文件，web.xml文件将指定配置文件、配置必要的Servlet、Filter 和 Listener。

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<!--  Spring配置 以及 Spring监听器 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
<!--  Spring MVC DispatcherServlet -->
  <servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

<!--  乱码过滤器-->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

3、/ resource / spring.xml 文件（applicationContext.xml）

　　Spring配置文件，组件扫描、加载数据库的properties文件、配置数据源、SessionFactory、Mapper、事务管理器以及开启事务注解。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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">
    <!--    加载文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!--    组件扫描-->
    <context:component-scan base-package="com.miz">
        <!--    排除 Spring 对 Controller 的扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--    配置数据源 -->
    <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}"/>
        <property name="initialSize" value="${jdbc.initialSize}"/>
        <property name="maxActive" value="${jdbc.maxActive}"/>
    </bean>

    <!--    配置SessionFactory -->
    <bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis.xml"/>
        <property name="globalConfig" ref="globalConfig"/>
        <property name="typeAliasesPackage" value="com.miz.entity"/>
    </bean>

    <!--    mybatis plus -->
    <bean id="globalConfig" class="com.baomidou.mybatisplus.core.config.GlobalConfig">
        <property name="dbConfig" ref="dbConfig"/>
    </bean>

    <bean id="dbConfig" class="com.baomidou.mybatisplus.core.config.GlobalConfig$DbConfig">
        <property name="idType" value="AUTO"/>
        <!--        <property name="tablePrefix" value="tbl_"></property>-->
    </bean>


    <!-- 定义Mapper接口扫描器-->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.miz.mapper"/>
    </bean>


    <!--定义事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 开启事务注解支持 -->
    <tx:annotation-driven transaction-manager="transactionManager" />

</beans>

4、/ resource / jdbc.properties 文件

　　数据库的参数配置文件

jdbc.driverClassName=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/dcms_ssm
jdbc.username=root
jdbc.password=123456
# 初始化连接数量
jdbc.initialSize=5
# 最大连接数
jdbc.maxActive=10

5、/ resource / mybatis.xml 文件

　　对mybatis进行配置，而数据源、bean以及mapper 在本文都交由Spring管理

<?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>

</configuration>

6、/ resource / springMVC.xml 文件

　　对SpringMVC进行配置，开启组件扫描、注解驱动、视图解析器以及开放静态资源访问

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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
">
<!--    启动注解驱动-->
    <mvc:annotation-driven/>

<!--    bean注解扫描-->
    <context:component-scan base-package="com.miz.controller"/>

<!--    配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

<!--    原始容器查找,配置静态资源-->
    <mvc:default-servlet-handler/>

</beans>
