SSM環境搭建回顧-有解無憂

編輯器：IDEA

系統：Win 10

包管理：maven

SSM：SpringMvc、Spring、MyBatis

一、搭建 maven的父子工程

先建立 ssm 的父工程 review_ssm

再分別建立 domain、dao、service、utils子模塊，以及最后創建使用maven的webapp骨架構建的 web模塊

構建 web骨架的時候記得補全目錄

二、導包

在父工程中匯入相關的依賴，

        <slf4j.version>1.6.6</slf4j.version>

        <oracle.version>11.2.0.1.0</oracle.version>
        <mybatis.version>3.4.5</mybatis.version>
        <spring.security.version>5.0.1.RELEASE</spring.security.version>

            </plugins>

三、開始 ssm整合組態檔的撰寫

撰寫物體類（domain），撰寫業務介面（service），撰寫持久層介面（dao）

spring環境搭建（applicationContext）撰寫業務層實作類（使用注解Service）

==========applicationContext============

<!-- 開啟注解掃描，管理service和dao -->
<context:component-scan base-package="com.cnblogs.ssm.service">
</context:component-scan>
<context:component-scan base-package="com.cnblogs.ssm.dao">
</context:component-scan>

springmvc環境搭建以及，spring和mvc的整合

========web.xml========


<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://xmlns.jcp.org/xml/ns/javaee"

	<!-- 配置加載類路徑的組態檔 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>

	</context-param>

<!-- 配置監聽器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 配置監聽器，監聽request域物件的創建和銷毀的 -->
	<listener>
		<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
	</listener>

	


	<!-- 前端控制器（加載classpath:springmvc.xml 服務器啟動創建servlet） -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 配置初始化引數，創建完DispatcherServlet物件，加載springmvc.xml組態檔 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<!-- 服務器啟動的時候，讓DispatcherServlet物件創建 -->
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

	<!-- 解決中文亂碼過濾器 -->
	<filter>
		<filter-name>characterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>

		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>characterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 委派過濾器 -->
	<filter>

		<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
	</filter>
	<filter-mapping>

=========spring-mvc.xml=========

	<!-- 掃描controller的注解，別的不掃描 -->

	<!-- 配置視圖決議器 -->

	<mvc:resources location="/img/" mapping="/img/**" />
	<mvc:resources location="/js/" mapping="/js/**" />
	<mvc:resources location="/plugins/" mapping="/plugins/**" />

	<!-- 開啟對SpringMVC注解的支持 -->
	<mvc:annotation-driven />

	<!-- 
		支持AOP的注解支持，AOP底層使用代理技術
		JDK動態代理，要求必須有介面
		cglib代理，生成子類物件，proxy-target- 默認使用cglib的方式
	-->
	<aop:aspectj-autoproxy proxy-target-/>
	
</beans>

spring和 mybatis的整合（主要是配置資料源和sqlsessionFactory）

=========applicationContext=============

<context:property-placeholder location="classpath:db.properties"/>
	<!-- 配置連接池 -->
	<bean id="dataSource" >
   		<property name="driverClass" value="https://www.cnblogs.com/llf7/p/${jdbc.driver}" />
   		<property name="jdbcUrl" value="https://www.cnblogs.com/llf7/p/${jdbc.url}" />
