SSM整合环境搭建demo

1.项目目录结构

2.项目中用的jar包

3.web.xml（其中主要配置spring与springmvc）

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
 3 <web-app id="WebApp_ID">
 4     <!-- spring配置 -->
 5     <context-param>
 6         <param-name>contextConfigLocation</param-name>
 7         <param-value>classpath:applicationContext.xml</param-value>
 8     </context-param>
 9     <listener>
10         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
11     </listener>
12
13     <!-- springmvc配置 -->
14     <servlet>
15         <servlet-name>springmvc</servlet-name>
16         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
17         <init-param>
18             <param-name>contextConfigLocation</param-name>
19             <param-value>classpath:springMVC-servlet.xml</param-value>
20         </init-param>
21         <load-on-startup>1</load-on-startup>
22     </servlet>
23     <servlet-mapping>
24         <servlet-name>springmvc</servlet-name>
25         <url-pattern>/</url-pattern>
26     </servlet-mapping>
27 </web-app>

4.spring配置文件applicationContext.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

27     </bean>
28
29     <bean id="transactionManager"
30         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

36     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
37         <property name="dataSource" ref="dataSource" />
38         <!-- 指定mybatis配置文件 -->
39         <property name="configLocation" value="classpath:mybatis-config.xml"></property>
40     </bean>
41
42     <mybatis-spring:scan base-package="com.hxlz.mapper"/>
43 </beans>

5.springmvc配置文件springMVC-servlet.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 8         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
 9
10     <!-- 只扫描标了controller注解的控制器 -->
11      <context:component-scan base-package="com.hxlz" use-default-filters="false">
12         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
13     </context:component-scan>
14
15     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
16         <property name="prefix" value="/WEB-INF/view/"></property>
17         <property name="suffix" value=".jsp"></property>
18     </bean>
19
20     <mvc:view-controller path="/" view-name="index"/>
21
22     <mvc:annotation-driven></mvc:annotation-driven>
23     <mvc:default-servlet-handler/>
24 </beans>

6.mybatis配置文件mybatis-config.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE configuration
 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
 4 "http://mybatis.org/dtd/mybatis-3-config.dtd">
 5 <configuration>
 6     <settings>
 7         <setting name="mapUnderscoreToCamelCase" value="true" />
 8         <setting name="lazyLoadingEnabled" value="true"/>
 9         <setting name="aggressiveLazyLoading" value="false"/>
10     </settings>
11
12     <typeAliases>
13         <typeAlias alias="Employee" type="com.hxlz.bean.Employee" />
14     </typeAliases>
15
16 </configuration>

7.具体的业务逻辑的代码就不贴了，整合的环境基本上就是这个样子了。

内附上mybaits整合spring的官方给的demo：https://github.com/mybatis/jpetstore-6，希望一起成长，交流，学习。
