1. 项目环境准备
1.1. 技术选型
整个项目使用的SSM框架 SpringMVC，Spring，MyBatis，mysql数据库，Shiro安全框架
1.2. 使用Maven创建Web项目
|
|
1.3. 引入maven项目pom文件依赖的和插件配置
Maven的pom文件集成了整个项目所需要的绝大部分框架依赖，后期其他依赖在实际开发中按需引入集合
|

2. 框架集成配置
整个框架的 Spring，SpringMVC采用 xml方式配置（也可以自定义使用注解配置），
所以需要创建准备对应的xml配置文件
|
spring.xml |
Spring框架的主配置文件，主要 |
|
springmvc.xml |
SpringMVC配置文件 |
|
db.properties |
数据库连接配置文件 |
|
log4j.properties |
Log4j日志配置文件 |
其他配置文件后面使用到按需配置
使用Web项目，需要将框架位置到web.xml中才能生效
2.1. spring.xml文件配置
Spring.xml配置文件，主要配置spring注解配置包扫描组件位置，MyBatis代理对象创建
事务管理的配置
|
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd ">
<!-- 配置包扫描位置 --> <context:component-scan base-package="cn.zj.logistics" />
<!-- 读取 db.properties数据库配置文件 --> <context:property-placeholder location="classpath:db.properties" />
<!-- 配置 druid 连接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="maxActive" value="${jdbc.maxActive}" /> </bean>
<!-- 配置SqlSessionFactory对象的创建 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入插件 --> <property name="plugins"> <array> <bean class="com.github.pagehelper.PageInterceptor"> <property name="properties"> <value> <!-- 方言 --> helperDialect=mysql </value> </property> </bean> </array> </property> <property name="dataSource" ref="dataSource" />
<!-- 配置映射文件 --> <property name="mapperLocations"> <array> <value>classpath:cn/sxt/edu/mapper/*Mapper.xml</value> </array> </property>
<!-- 配置别名，使用包扫描配置 --> <property name="typeAliasesPackage" value="cn.zj.logistics.pojo" />
<!-- 读取mybatis-config.xml文件（使用个性化配置，日志，缓存等等） --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean>
<!-- 使用包扫描的方式创包下面所有接口对应的代理对象 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 配置包扫描创建代理对象的位置 --> <property name="basePackage" value="cn.zj.logistics.mapper" />
<!-- 注意： 需要注入SqlSessionFactory工厂对象的名称 ！！！ --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean>
<!-- MyBatis的事务配置 -->
<!-- 配置事务管理器 ： what？ -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 注入数据源 --> <property name="dataSource" ref="dataSource" /> </bean>
<!-- Spring事务配置 ： when? --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- dql操作，一般都是只读事务 --> <tx:method name="get*" read-only="true" propagation="REQUIRED" /> <tx:method name="find*" read-only="true" propagation="REQUIRED" /> <tx:method name="select*" read-only="true" propagation="REQUIRED" /> <tx:method name="query*" read-only="true" propagation="REQUIRED" /> <!-- dml操作，非只读事务 --> <tx:method name="*" read-only="false" /> </tx:attributes> </tx:advice> <!-- 配置AOP切面，将事务切到Service层 --> <aop:config> <!-- 切入点 ：where？ --> <aop:pointcut expression="execution(* cn.zj.logistics.service.impl.*.*(..))" id="pt" /> <!-- 切面：切入点+通知 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="pt" /> </aop:config> </beans>
|
2.2. springmvc.xml配置
Springmvc.xml主要配置一些springmvc框架相关配置，开启注解驱动，视图解析器，静态资源处理等等
|
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd ">
<!-- 开启SpringMVC的注解驱动 --> <mvc:annotation-driven />
<!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 支持静态资源处理 --> <mvc:default-servlet-handler/>
</beans> |
2.3. db.properties配置文件
数据库连接配置文件
|
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/logistics?characterEncoding=utf-8 jdbc.username=root jdbc.password=root jdbc.maxActive=10 |
2.4. log4j.properties日志配置文件
|
# Global logging configuration log4j.rootLogger=ERROR, stdout # MyBatis logging configuration... log4j.logger.cn.zj.logistics=TRACE # Console output... log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n |
2.5. web.xml
Web.xml作为动态web项目的入口文件，spring和springmvc框架集成相关配置需要放到在此文件下配置
|
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
<!-- 配置spring的授权过滤器，让spring来管理shiro框架 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <!-- 配置shirofilter的生命周期交给servlet管理 --> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<!-- 字符编码过滤器 --> <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>
<!-- 1.配置SpringMVC的前端控制器(总控) --> <servlet> <servlet-name>MVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring*.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>
<servlet-mapping> <servlet-name>MVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping>
<!-- 设置项目的欢迎页面 --> <welcome-file-list> <welcome-file>/login.jsp</welcome-file> </welcome-file-list> </web-app> |
1.1. Springmvc框架集成的测试
1.1.1. 新建一个AdminController
|
package cn.zj.logistic.controller;
import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;
@Controller @RequestMapping("/admin") public class AdminController {
//后台用户列表显示页面 @RequestMapping("/adminPage.do") public String adminPage() {
return "admin_list"; } } |
1.1.2. adminPage.jsp管理员操作jsp文件
因为springmvc框架配置了视图解析器，所有SpringMVC控制器请求默认都请求转发
到 WEB-INF/view 目录下面
在WEB-INF目录下面新建一个view目录，在下面再创建一个 adminPage.jsp文件
