Maven项目下详细的SSM整合流程

文章目录

🎉SSM整合流程
- 一、两个容器整合✨
- - 1、先准备好数据库config.properties连接、mybatis-config.xml🎊
  - 2、容器一：优先配置spring.xml文件🎊
  - 3、容器二：配置springMVC.xml文件🎊
  - 4、Tomcat整合spring容器、springMVC容器，webapp文件下的web.xml文件🎊
- 二、一个容器整合
- - 1、现在去掉了spring.xml文件，将spring.xml文件的内容放到springMVC🎊
  - 2、Tomcat整合springMVC容器，webapp文件下的web.xml文件🎊

🎉SSM整合流程

分为两种：两个容器整合

一个容器整合

本项目的路径参考：

注意：优先maven项目的pom.xml文件里导入jar包依赖：

一、两个容器整合✨

1、先准备好数据库config.properties连接、mybatis-config.xml🎊

（1）数据库config.properties连接

driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/emp?serverTimeZone=Asia/ShangHai&useUnicode=true&characterEncoding=utf8&useSSL=false
username=root
password=nigx=0128

（2）mybatis-config.xml

<?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>

    <!-- <properties resource="config.properties"> -->
    <!-- </properties> -->

    <settings>
        <!--将表中字段的下划线自动转换为驼峰-->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
        <!-- 如果需要更改一级缓存的范围，可以在Mybatis的配置文件中，在下通过localCacheScope指定。 -->
        <!-- <setting name="localCacheScope" value="STATEMENT"/> -->
    </settings>

    <!--  类型别名
      配置各个标签时，需要遵守前后顺序-->
    <typeAliases>
        <package name="com.pojo"/>
    </typeAliases>

    <!--    <typeAliases>-->
    <!--        <typeAlias alias="user" type="com.pojo.User"></typeAlias>-->
    <!--        <typeAlias type="com.pojo.Employee"></typeAlias>-->
    <!--        <typeAlias type="com.pojo.Log"></typeAlias>-->
    <!--        <typeAlias type="com.pojo.Dept"></typeAlias>-->
    <!--    </typeAliases>-->
    <!--  environments：配置数据库的连接环境信息，可以配置多个environment，通过default属性切换不同的environment  -->
    <!-- <environments default="development"> -->

    <!--     <environment id="development"> -->
    <!--         <transactionManager type="JDBC"/> -->
    <!--         &lt;!&ndash;数据库连接池&ndash;&gt; -->
    <!--         <dataSource type="POOLED"> -->
    <!--             &lt;!&ndash;数据库的连接信息&ndash;&gt; -->

    <!--         </dataSource> -->
    <!--     </environment> -->
    <!-- </environments> -->


    <mappers>
        <!--加载SQL映射文件-->
        <!--<mapper resource="nigaoxian\mapper\UserMapper.xml"/>-->

        <!--  Mapper 代理方式，在spring容器映射过就不需要配置了-->
        <!-- <package name="com.dao"/> -->
    </mappers>
</configuration>

2、容器一：优先配置spring.xml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"

           http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 2*3+1 -->

    <!--扫描组件（除控制层）-->
    <context:component-scan base-package="com.service,com.service.serviceImpl,com.interceptor,com.exception">
        <!-- 按照注解进行排除，标注了指定注解的组件不要扫描 -->
        <!--        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>-->
        <!-- 指定排除某个具体的类，按照类排除  -->
        <!-- <context:exclude-filter type="assignable" expression="com.controller.EmpController"/> -->
    </context:component-scan>


    <!-- 配置数据源 -->
    <!--引入config.properties-->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:config.properties</value>
            </list>
        </property>
    </bean>

        <property name="user" value="${username}"></property>
        <property name="password" value="${password}"></property>
    </bean>

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

    <!--
         开启事务的注解驱动，
         将使用注解 @Transactional 标识的方法或类中所有的方法进行事务关联
    -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

    <!-- 配置SqlSessionFactoryBean，可以直接在Spring的IOC中获取SqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 设置MyBatis的核心配置文件的路径 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!-- 设置数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 设置类型别名，默认为类名 -->
        <!-- <property name="typeAliasesPackage" value="com.pojo"/> -->
        <!-- 设置映射文件所在的包，只有在映射文件的包和mapper接口的包不一致时需要设置 -->
        <property name="mapperLocations" value="classpath:com/dao/*.xml"/>
        <!--引入分页插件-->

       <!--     </array> -->
       <!-- </property> -->
    </bean>

    <!--
          配置mapper接口的扫描配置，由mybatis-spring提供，可以将指定包下所有的mapper接口创建动态代理，
          并将这些动态代理作为IOC容器的bean管理，可以直接在Spring的IOC中获取Mapper接口了。
    -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="com.dao"/>
    </bean>
</beans>

3、容器二：配置springMVC.xml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"
       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/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 启动mvc注解驱动 -->
    <mvc:annotation-driven/>

    <!-- 配置扫描的包 -->
    <context:component-scan base-package="com.controller"/>

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

    <mvc:cors>
        <mvc:mapping path="/**" allowed-origins="*" allowed-headers="*" allowed-methods="*" allow-credentials="false"
                     max-age="3600"/>
    </mvc:cors>
    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean id="corsInterceptor" class="com.interceptor.CORSInterceptor"/>

            <bean id="loginInterceptor" class="com.interceptor.LoginInterceptor"/>
        </mvc:interceptor>
    </mvc:interceptors>
</beans>

4、Tomcat整合spring容器、springMVC容器，webapp文件下的web.xml文件🎊

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

         version="4.0">


    <!-- tomcat整合spring -->

    </listener>

    <!--设置spring配置文件自定义的位置和名称-->
    <context-param>
        <param-name>contextConfigLocation</param-name>

二、一个容器整合

1、现在去掉了spring.xml文件，将spring.xml文件的内容放到springMVC🎊

springMVC.xml文件如下：

<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"
       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/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
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<!-- 2*3+1 -->

    <!--扫描组件（除控制层）-->
    <context:component-scan base-package="com.service,com.service.serviceImpl,com.interceptor,com.exception">
        <!-- 按照注解进行排除，标注了指定注解的组件不要扫描 -->
        <!--        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>-->
        <!-- 指定排除某个具体的类，按照类排除  -->
        <!-- <context:exclude-filter type="assignable" expression="com.controller.EmpController"/> -->
    </context:component-scan>


    <!-- 配置数据源 -->
    <!--引入config.properties-->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:config.properties</value>
            </list>
        </property>
    </bean>
    <!-- 配置数据参数与连接属性 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${driver}"></property>
        <property name="maxPoolSize" value="100"></property>
        <property name="minPoolSize" value="30"></property>
        <property name="jdbcUrl" value="${url}"></property>
        <property name="user" value="${username}"></property>
        <property name="password" value="${password}"></property>
    </bean>

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

    <!--
         开启事务的注解驱动，
         将使用注解 @Transactional 标识的方法或类中所有的方法进行事务关联
    -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

    <!-- 配置SqlSessionFactoryBean，可以直接在Spring的IOC中获取SqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 设置MyBatis的核心配置文件的路径 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!-- 设置数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 设置类型别名，默认为类名 -->
        <!-- <property name="typeAliasesPackage" value="com.pojo"/> -->
        <!-- 设置映射文件所在的包，只有在映射文件的包和mapper接口的包不一致时需要设置 -->
        <property name="mapperLocations" value="classpath:com/dao/*.xml"/>
        <!--引入分页插件-->
       <!-- <property name="plugins"> -->
       <!--     <array> -->
       <!--         <bean class="com.github.pagehelper.PageInterceptor"/> -->
       <!--     </array> -->
       <!-- </property> -->
    </bean>

    <!--
          配置mapper接口的扫描配置，由mybatis-spring提供，可以将指定包下所有的mapper接口创建动态代理，
          并将这些动态代理作为IOC容器的bean管理，可以直接在Spring的IOC中获取Mapper接口了。
    -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="com.dao"/>
    </bean>

    <!-- 启动mvc注解驱动 -->
    <mvc:annotation-driven/>

    <!-- 配置扫描的包 -->
    <context:component-scan base-package="com.controller"/>

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

    <mvc:cors>
        <mvc:mapping path="/**" allowed-origins="*" allowed-headers="*" allowed-methods="*" allow-credentials="false"
                     max-age="3600"/>
    </mvc:cors>
    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean id="corsInterceptor" class="com.interceptor.CORSInterceptor"/>
        </mvc:interceptor>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <mvc:exclude-mapping path="/login"/>
            <mvc:exclude-mapping path="/register"/>
            <bean id="loginInterceptor" class="com.interceptor.LoginInterceptor"/>
        </mvc:interceptor>
    </mvc:interceptors>
</beans>

2、Tomcat整合springMVC容器，webapp文件下的web.xml文件🎊

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<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">


   
    <!-- tomcat整合springMVC -->
    <!-- 配置SpringMVC的前端控制器 -->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 设置SpringMVC的配置文件的位置和名称 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springMVC.xml</param-value>
        </init-param>
        <!-- 将DispatcherServlet的初始化时间提前到服务器启动时-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 为什么使用/，并且这里为什么会默认放行jsp？
     设置/是为了兜底的，因为只有一个servlet，就是默认为DispatcherServlet的servlet，需要使用这个servlet拦截
     请求。因为jsp底层本身就是servlet，设置多个servlet此时只映射的是DispatcherServlet
     -->
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>


</web-app>
