19 SSM整合,SSM框架快速搭建

零、SSM框架demo下载


 

以下配置与demo均为maven项目。

一、依赖添加(pom.xml)


主要配置的依赖包有:

spring框架(spring-context),springMVC框架(spring-webmvc),MyBatis框架(mybatis与mybatis-spring),模板解析框架(thymeleaf与thymeleaf-spring4),JDBC(spring-jdbc与mysql-connector-java)

可选依赖包:

数据库连接池(commons-dbcp),Junit单元测试(junit)

			<artifactId>junit</artifactId>
			<version>4.13</version>
			<scope>test</scope>
		</dependency>
	</dependencies>

  

二、web.xml配置


配置springMVC(DispatcherServlet的配置)

第8行表示:在resource文件夹下寻找spring与springmvc的配置文件spring-mvc.xml(名称可改)

第15行表示:对所有以.do结尾的请求进行拦截对其分配处理方法(SpringMVC原理)。

配置全局编码

固定写法

<!-- 配置springMVC的DispatcherServlet -->
	<servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
	<!-- param-value节点:配置需要加载的Spring的配置文件的位置 -->
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<!-- url-pattern节点:配置SpringMVC框架处理哪些请求 -->
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	<!-- 配置全局编码 -->
	<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>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

  

三、spring-dao.xml与spring-mvc配置


spring-dao.xml与spring-mvc.xml存放在resource文件夹下。

1.spring-dao.xml

spring-dao即mybatis相关的配置信息。需要自行改动的两个地方:

  • mapper xml文件位置:在下面配置中,<property name="mapperLocations">中的value表示resource文件夹下的mappers下的所有.xml文件,value为可能改动的属性。
  • mapper接口位置:在下面配置中,<property name="basePackage">中的value表是mapper对应的mapper接口所在的包,value为可能改动的属性。
<?xml version="1.0" encoding="UTF-8"?>

	<!-- 读取jdbc.properties -->
	<util:properties id="jdbc" location="classpath:jdbc.properties"></util:properties>
	
	<!-- 配置数据源:BasicDataSource -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

	</bean>
	
	<!-- 配置MapperScannerConfigurer -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	    <property name="basePackage" value="cn.tedu.mybatis"></property>
	</bean>
	<!-- SqlSessionFactoryBean -->
	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
	    <!-- 指定配置SQL语句的XML文件在哪里 -->
	    <property name="mapperLocations" value="classpath:mappers/*.xml"></property>
	    <!-- 自定连接数据库的配置文件源 -->
	    <property name="dataSource" ref="dataSource"></property>
	</bean>
</beans>

  

2.spring-mvc.xml

spring-mvc.xml即spring与springMVC的配置文件,名字可以任意,但是要和web.xml中引用时保持一致。

其中,需要自定义的地方有:

  • 组件扫描根包:base-package
  • 模板解析器的perfix与suffix,分别表示前缀与后缀,前缀表示页面模板所在的地址(这里为resource文件夹下的templates文件夹),后缀表示模板类型(这里为 .html)
<?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:jdbc="http://www.springframework.org/schema/jdbc"  
	xmlns:jee="http://www.springframework.org/schema/jee" 
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:mvc="http://www.springframework.org/schema/mvc"

		http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd">
	
	<!-- 组件扫描 -->
	<!-- 可修改处1:base-package属性:被扫描的根包 -->
	<context:component-scan base-package="cn.tedu.spring"></context:component-scan>
	
	<!-- 配置模版解析器 -->
	<!-- ClassLoaderTemplateResolver:当把模版页面放在src/main/resources下时,必须使用这个模版解析器 -->
	<!-- ServletContextTemplateResolver:当把模版页面放在webapp下时,必须使用这个模版解析器 -->
	<!-- 注入prefix属性:配置前缀 -->
	<!-- 注入suffix属性:配置后缀 -->
	<!-- 前缀 + 处理请求的方法的返回值 + 后缀 必须对应html文件的位置 -->
	<bean id="templateResolver" class="org.thymeleaf.templateresolver.ClassLoaderTemplateResolver">
		<property name="prefix" value="/templates/"></property>
		<property name="suffix" value=".html"></property>
		<property name="characterEncoding" value="utf-8"></property>
		<property name="cacheable" value="false"></property>
		<property name="templateMode" value="HTML"></property>
	</bean>
	
	<!-- 配置模版引擎 -->
	<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
		<property name="templateResolver" ref="templateResolver"></property>
	</bean>
	
	<!-- 配置Thymeleaf视图解析器 -->
	<bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
		<property name="templateEngine" ref="templateEngine"></property>
		<property name="characterEncoding" value="utf-8"></property>
	</bean>

	
</beans>

  

四、properties文件配置


 1.jdbc.properties文件

文件存放在resource文件下,文件名称不可改,文件中数据可改。

其中,此字符串不改:useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai

url=jdbc:mysql://localhost:3306/tedu_ums?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
driver=com.mysql.cj.jdbc.Driver
username=root
password=xiaohei1120
initialSize=10
maxActive=50
