ssm框架 spring的主配置文件 spring-mvc主配置文件 web.xml配置文件(基礎的配置文件)

1、spring主配置文件

<?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:context="http://www.springframework.org/schema/context" 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/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--第一步，掃描service-->
        <context:component-scan base-package="com.zmh.ssm.service.impl"></context:component-scan>
        <!--第二步，加載jdbc.properties-->
        <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
        <!--第三步，創建dbcp數據源連接池-->
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${driver}"></property>
            <property name="url" value="${url}"></property>
            <property name="username" value="${user}"></property>
            <property name="password" value="${password}"></property>
        </bean>
        <!--第四步，創建mybatis的工廠類對象-->
        <bean class="org.mybatis.spring.SqlSessionFactoryBean">
            <!--指定數據源-->
            <property name="dataSource" ref="dataSource"></property>
            <!--加載mybatis的映射文件  在value中可以使用*號通配符-->
            <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
        </bean>
        <!--第五步，在spring的工廠中生成dao接口的實現類對象-->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <!--指定要掃描哪個包下面所有的dao接口-->
            <property name="basePackage" value="com.zmh.ssm.dao"></property>
        </bean>
        <!--第六步，創建spring的事物管理器-->
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"></property>
        </bean>
        <!--第七步，聲明以注解的方式配置聲明式事物-->
        <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

2、spring-mvc主配置文件

<?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:context="http://www.springframework.org/schema/context"
       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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--掃描控制器包-->
    <context:component-scan base-package="com.zmh.ssm.controller"></context:component-scan>
        <!--聲明以注解的方式配置spring mvc 相當於配置類
            RequestMappingHandlerMapping   處理器映射器
            RequestMappingHandlerAdapter   處理器適配器
        -->
        <mvc:annotation-driven></mvc:annotation-driven>
        <!--配置spring mvc默認的jsp視圖解析器-->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <!--配置返回視圖的前綴-->
            <property name="prefix" value="/WEB-INF/jsp/"></property>
            <!--配置返回視圖的后綴-->
            <property name="suffix" value=".jsp"></property>
        </bean>
</beans>

3、web.xml配置文件

<?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"

         version="4.0">
    <!--配置spring的核心控制器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!--手動指定spring的主配置文件的位置和名稱-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>
    </context-param>
    <!--配置spring mvc的前端控制器-->
    <servlet>
        <servlet-name>spring-mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--指定spring mvc的主配置文件的位置和名稱-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring-mvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    <!--配置編碼過濾器，解決post請求中文亂碼問題-->
    <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>
        <init-param>
            <param-name>forceResponseEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>
