SSM整合

ssm整合配置文件

1.新建一个maven项目

（1）：maven的注意事项

1）maven版本问题：

maven与idea版本关系：

1.IDEA22021兼容maven3.8.1以及之前的版本

2.IDEA2020兼容maven3.6.3以及之前的版本

3.IDEA2018兼容maven3.6.1以及之前的版本

因版本不对提示的报错信息：

Unable to import maven project: See logs for details

日志中的信息：

2021-12-22 19:48:40,564 [ 690796] ERROR - plication.impl.ApplicationImpl - Last Action: ShowIntentionActions

    <!--在build中配置resources，来防止我们资源导出失败的问题-->
    <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>

                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

2.mybatis的配置文件

（1）：mybatis配置文件的命名：mybatis-config.xml（推荐）

（2）：mybatis-config：配置文件内容

<?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>
    <!--配置数据源，交给spring去做-->

       <!--typeAliases
        typeAliases:别名处理器，可以为java类型起别名：
            1.typeAliases:为某个java类型起别名
                type：指定要起别名的类型的全类名，默认为类名首字母小写：employee
                alias；指定新的别
            2.package:为某个包下的所有类批量起别名(默认别名)
                name:指定包名
            3.可以在需要起别名的类上加上@Alias()为其起别名
        -->
    <typeAliases>
        <package name="SSM.pojo"></package>
    </typeAliases>

    <mappers>
        <mapper resource="BookMapper.xml"></mapper>
    </mappers>

</configuration>

3.Spring的配置文件

为便于理解将spring配置文件拆来来写：

拆开后记得将配置文件合起来：

具体配置如下：

（1）applicationContext.xml:将spring配置文件整合

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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">

    <import resource="classpath:spring-dao.xml"></import>
    <import resource="classpath:spring-service.xml"></import>
    <import resource="classpath:spring-mvc.xml"></import>

</beans>

（2）spring-dao.xml:配置数据库文件以及创建出SqlSessionFactory对象

数据库文件：database.properties

对应的mysql版本为8.0以上：

jdbc.driver=com.mysql.cj.jdbc.Driver
#时区配置 &serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=123456

<?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"
       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">

    <!-- 引入数据库的配置文件 -->
    <context:property-placeholder location="classpath:database.properties" />
    <!-- Spring用来控制业务逻辑。数据源、事务控制、aop -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--创建出SqlSessionFactory对象  -->
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!-- configLocation指定全局配置文件的位置 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
        <!--mapperLocations: 指定mapper文件的位置-->
        <!--<property name="mapperLocations" value="classpath:*.xml"></property>-->
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
      <property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"></property>
      <property name="basePackage" value="SSM.dao"></property>
  </bean>
</beans>

（3）spring-service.xml:service层主要用于实现事务的操作

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

    <!--扫描service下的包-->
    <context:component-scan base-package="SSM"></context:component-scan>
    <!--声明式事务-->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!-- 开启基于注解的事务 -->
    <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>
</beans>

（4）spring-mvc：见SpringMVC配置文件

4.SpringMVC配置文件

（1）生成web项目：

（2）web.xml配置文件：

着重注意：classpath：只能找到web.xml的上下文路径，直接配置spring-mvc并不能找到spring-mvc.xml文件，因此需要配置成spring的总文件applicationContext.xml。

<param-value>classpath:applicationContext.xml</param-value>

<?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_3_1.xsd"
         version="3.1">
    <!--DispathchServlet-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!--乱码过滤-->
    <filter>
        <filter-name>encodingFilter</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>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

（3）spring-mvc.xml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
       https://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">


    <!--1.注解驱动-->
    <mvc:annotation-driven></mvc:annotation-driven>
    <!--2.静态资源过滤-->
    <!--开放对静态资源的访问-->
    <mvc:default-servlet-handler/>
    <!--3.扫描包-->
    <!--扫描组件-->
    <context:component-scan base-package="SSM.controller"></context:component-scan>
    <!--4.视图解析器-->
    <!--配置页面解析器-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <!-- 视图前缀 -->
          <property name="prefix" value="/WEB-INF/jsp/"/>
          <!-- 视图后缀 -->
          <property name="suffix" value=".jsp"/>
    </bean>

</beans>
