SSM框架可分爲三部分,持久層-dao,業務層-biz,表現層-web
項目結構可分爲如下部分:
持久層主要配置
數據源
<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/shh?useUnicode=true&characterEncoding=utf-8"/>
<property name="username" value="root"/>
<property name="password" value=""/>
</bean>
session工廠
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.summer.shh.entity"/>
<property name="configLocation" value="classpath:mybatisConfig.xml"></property>
</bean>
映射器幾口
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sessionFactory"/>
<property name="basePackage" value="com.summer.shh.dao"/>
</bean>
xml配置文件如下:
<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"
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">
//配置上下文掃描,自動掃描dao下所有類
<context:component-scan base-package="com.summer.shh.dao"/>
<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/shh?useUnicode=true&characterEncoding=utf-8"/>
<property name="username" value="root"/>
<property name="password" value=""/>
</bean>
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.summer.shh.entity"/>
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

表現層配置
導入事務層配置
<import resource="spring-biz.xml"/>
啓動上下文配置,自動掃描controller包下所有類
<context:component-scan base-package="com.summer.shh.controller"/>
開啓事務驅動
<mvc:annotation-driven/>
靜態資源處理
//靜態資源交給servlet處理,不用mvc處理
<mvc:default-servlet-handler/>
配置視圖轉換器
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
xml配置如下
<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"

注意
1.持久層,業務層創建的模塊都爲空模塊,而表現層創建的模塊是maven下的webapp模塊
2.表現層pom配置中注意這裏必須爲war包
<artifactId>shh_web</artifactId>
<packaging>war</packaging>
接下來配置web.xml配置,因爲web項目啓動只會讀一個配置文件,這個配置文件就是web.xml,我們希望它讀取mvc.xml,因此需要在web.xml配置
web.xml配置如下
<?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">
<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:spring-web.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>
</web-app>
注意web.xml在WEB-INF目錄下
SSM父模塊pom配置
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.summer</groupId>
<artifactId>shh</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<modules>
<module>shh_dao</module>
<module>shh_biz</module>
<module>shh_web</module>
</modules>
<properties>
<spring.version>4.0.2.RELEASE</spring.version>
</properties>
</project>
注意創建父模塊後,由於沒有具體的邏輯代碼,因此可刪除src目錄
SSM框架配置大概如此,結構大概如下
持久層結構
業務層結構
表現層結構
SSM框架搭建結束
