SSM框架搭建

Posted 2022-08-19 jump233

1.启动项从web.xml

<!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>
    <!--过滤器-->
    <filter>
        <filter-name>character</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>character</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--核心控制器-->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
<welcome-file-list>
    <welcome-file>/main.html</welcome-file>
</welcome-file-list>
</web-app>

2.springMVC-servlet.xml的配置在WEB-INF建立

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       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/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.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
">
<!--1.全局扫描包(spring):-->
<context:component-scan base-package="cn.kgc"/>

<!--2.MVC注解驱动(springMVC):-->
<mvc:annotation-driven/>

<!--3.驱动管理数据源-->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/kgc"/>
    <property name="username" value="root"/>
    <property name="password" value="ok"/>
</bean>

<!--4.SqlSessionFactoryBean-->
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="typeAliasesPackage" value="cn.kgc.vo"/>
    <!--sql语句写到xml里面-->
    <!--<property name="mapperLocations" value="classpath:mapper/*.xml"/>-->
    <!--引入分页插件-->
    <property name="plugins">
        <array>
            <bean class="com.github.pagehelper.PageHelper">
                <property name="properties">
                    <value>dialect=mysql</value>
                </property>
            </bean>
        </array>
    </property>
</bean>

<!--5.数据源事务管理：id必须是transactionMannger-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
    <property name="dataSource" ref="dataSource"/>
</bean>

<!--6.事务注解驱动:识别@Transactional :事务提交commit-->
<tx:annotation-driven/>

<!--7.映射扫描参数：spring+mybatis整合，不写实现类 ；帮助在底层去完成mapper实现类的类容，并在底层生成mapper实现的bean节点-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="cn.kgc.mapper"/>
</bean>

    <bean id="empServiceImpl" class="cn.kgc.service.EmpServiceImpl">

    </bean>
</beans>
