SSM框架整合
SSM框架整合
学完SSM之后，感觉记忆并不深刻，因此留笔记，以待后用。
1.开发环境搭建
自行百度
2.Java web项目创建
自行百度
3.SSM框架整合
这次整合分成了6个配置文件，分别是applicationContext.xml，jdbc.properties，spring-dao.xml，spring-service.xml，spring-mvc.xml，mybatis-config.xml。
3.1 Maven引入需要的JAR包
pom.xml文件
<!--?xml version="1.0" encoding="UTF-8"?-->

3.2 jdbc属性文件
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/easy_integration?characterEncoding=utf8&useSSL=true&useUnicode=true
jdbc.username=root
jdbc.password=123456
3.3 创建mybatis-config的文件
mybatis-config
<!--?xml version="1.0" encoding="UTF-8" ?-->
<configuration>
<!--配置日志-->
<!--
<settings>
<setting name="logImpl" value="LOG4J"/>
<setting name="cacheEnabled" value="true"/>
<setting name="autoMappingBehavior" value="FULL"/>
</settings>
-->
<!--别名-->
<typealiases>
<package name="com.bean">
</package></typealiases>
<!--<mappers>
<mapper class="com.dao.CommodityMapper"/>
</mappers>-->
</configuration>
3.4 创建spring的文件
spring-dao
<!--?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" xsi:schemalocation="http://www.springframework.org/schema/beans

</context:property-placeholder></beans>
spring-service
<!--?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" xsi:schemalocation="http://www.springframework.org/schema/beans

<!--扫描service下的包-->

<!--aop事务支持-->
</context:component-scan></beans>
spring-mvc
<!--?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemalocation="http://www.springframework.org/schema/beans

<!-- <com.bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxInMemorySize" value="5000000"/>
<property name="defaultEncoding" value="UTF-8"/>
</com.bean>-->
</mvc:default-servlet-handler></context:component-scan></mvc:annotation-driven></beans>
3.5 创建applicationContext.xml文件
applicationContext.xml
<!--?xml version="1.0" encoding="UTF-8"?-->
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="spring-dao.xml">
<import resource="spring-service.xml">
<import resource="spring-mvc.xml">
</import></import></import></beans>
3.6 配置web.xml文件
这里面对spring-mybatis.xml的引入以及配置的spring-mvc的Servlet就是为了完成SSM整合。
web.xml
<!--?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_4_0.xsd" version="4.0">
<!--配置核心控制器DispatcherServlet-->
<servlet>

<param-name>contextConfigLocation</param-name>

<load-on-startup>1</load-on-startup>
</servlet>
<!-- <context-param>
