大纲/内容

一、前期准备工作

1.创建SSM框架项目，选择骨架maven-archetype-webapp构建项目。要写achetypeCatagory、internal

2.groupId + artifactId + version（SNAP）提供当前项目的打包并发布的坐标

3.修改pom.xml，给maven项目添加上各种依赖的jar包

可以引入： ①spring大礼包（core,beans,context,expression,web,aop）：org.springframework  ~  spring-webmvc ②mysql驱动：mysql  ~  mysql-connector-java ③druid数据库连接池：com.alibaba  ~  druid ④mybatis持久层框架：org.mybatis  ~  mybatis ⑤spring整合mybatis：org.mybatis  ~  mybatis-spring ⑥分页插件：com.github.pagehelper  ~  pagehelper ⑦spring数据库相关的jdbc，tx（和事务aop有关）：org.springframework  ~  spring-jdbc ⑧servlet,jsp,jstl：javax.servlet  ~  servlet-api、jsp-api、jstl ⑨json解析：com.fasterxml.jackson.core  ~  jackson-core、jackson-databind、jackson-annotations ⑩日志log4j：org.slf4j  ~  slf4j-api；log4j  ~  log4j 11.文件上传：commons-io  ~  commons-io；commons-fileupload  ~  commons-fileupload 12.校验：org.hibernate.validator  ~  hibernate.validator 13.spring整合junit：org.springframework  ~  spring-test；junit  ~  junit 14.添加 aspectj的支持,它是AOP的具体实现：org.aspectj  ~  aspectjweaver 15.类中快速创建各种方法的lombok：org.projectlombok  ~  lombok

4.创建项目目录结构

5.准备数据库（前提是安装好了mybatis插件，可以之后给我们反向工程）

6.创建tomcat服务器，未上线阶段时添加 war exploded版本

二、开发阶段 ！！！（必须检查MemberController，MemberServiceImpl头上是否有添加注解）

1.选中要反向工程的表，自动生成entity、dao、mapper.xml

2.创建service层，并实现（在实现里调用dao接口）

3.创建controller层并实现

三、配置文件

1.jdbc.properties 数据库连接属性文件

可配置： ①驱动位置 ②数据库地址 ③用户名（mysql） ④密码（mysql）

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/member_db jdbc.user=root jdbc.password=root

2.log4j.properties mybatis框架的日志格式属性文件

直接引：

#log4j默认的配置文件，myBatis框架就去找log4j.properties日志文件 #log4j               级别      变量 #OFF(关闭日志输出)、FATAL(灾难) >ERROR(错误) > WARN(警告)、INFO(消息)> DEBUG(调试)、ALL(所有级别) log4j.rootCategory=DEBUG, stdout #定义stdout = 把日志类型信息写在终端上 log4j.appender.stdout=org.apache.log4j.ConsoleAppender #定义stdout日志的布局，使用的是样板布局 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout #定义stdout日志布局的转换样板 # %p: 级别   %t: thread  %C:类 %M:方法名  %L:行   %m: 日志信息  %n 换行 log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd} %p [%t] %C.%M(%L) | %m%n #只要是调用dao中的方法就会打印日志 #定义日志对应包中的类如果有日志输出的级别必须>=WARN的才输出 log4j.logger.com.liying.dao=DEBUG

3.mybatis-config.xml mybatis的核心配置文件

可配置： ①使用log4j实现mybatis框架的日志 ②设置别名（为了让mapper文件那边省事） ③分页插件

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration         PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration>               <settings>         <setting name="logImpl" value="log4j"/>     </settings>               <typeAliases>         <package name="com.liying.entity"/>     </typeAliases>          <plugins>         <plugin interceptor="com.github.pagehelper.PageInterceptor">             <property name="property" value="mysql"/>         </plugin>     </plugins> </configuration>

4.spring-mvc.xml springmvc配置文件 配置MVC结构所需要的东西

可配置： ①扫描包路径 ⑩格式转换器（由于该xml头上引得那些资源，已经定下了各种东西的配置顺序，所以放这） ②注解驱动（如果使用了格式转换器，就要加上conversion-service，不然用不了） ③配置视图处理器 ④上传文件 ⑤拦截器 ⑥静态资源处理 ⑦静态资源映射 ⑧跨域处理 ⑨异常处理

<?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">          <context:component-scan base-package="com.liying"/>          <bean name="csfb" class="org.springframework.context.support.ConversionServiceFactoryBean">         <property name="converters">             <list>                 <bean class="com.liying.util.StringToDateConvertor"/>             </list>         </property>     </bean>               <mvc:annotation-driven conversion-service="csfb"/>     <mvc:annotation-driven/>          <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">         <property name="prefix" value="/WEB-INF/jsp/"/>         <property name="suffix" value=".jsp"/>     </bean>          <bean class="org.springframework.web.multipart.commons.CommonsMultipartResolver">         <property name="defaultEncoding" value="utf-8"/>         <property name="uploadTempDir" value="/upload"/>         <property name="maxInMemorySize" value="1024000"/>         <property name="maxUploadSize" value="-1"/>     </bean>                    <mvc:default-servlet-handler/>          <mvc:resources mapping="/css/**" location="/static/css/"/>     <mvc:resources mapping="/js/**" location="/static/js/"/>     <mvc:resources mapping="/img/**" location="/static/img/"/>          <mvc:cors>         <mvc:mapping path="/**"                      allowed-origins="*"                      allow-credentials="false"                      allowed-headers="*"                      allowed-methods="GET,POST"                      max-age="3600"         />     </mvc:cors>           </beans>

5.spring-mybatis.xml spring整合的mybatis的配置文件 配置数据源>>创建 sqlsessionFactory>>生成 mapper 代理

可配置： ①引入属性文件 ②创建数据源 ③创建SqlSessionFactory ④扫描dao，做相应的映射 ⑤创建事务管理器 ⑥创建通知/监听者 ⑦设置切面/监听

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:context="http://www.springframework.org/schema/context"        xmlns:tx="http://www.springframework.org/schema/tx"        xmlns:aop="http://www.springframework.org/schema/aop"        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/tx http://www.springframework.org/schema/tx/spring-tx.xsd         http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">          <context:property-placeholder location="classpath:jdbc.properties"/>          <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">         <property name="driverClassName" value="${jdbc.driver}"/>         <property name="url" value="${jdbc.url}"/>         <property name="username" value="${jdbc.user}"/>         <property name="password" value="${jdbc.password}"/>     </bean>          <bean name="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">                  <property name="dataSource" ref="dataSource"/>                  <property name="configLocation" value="classpath:mybatis-config.xml"/>                  <property name="mapperLocations" value="classpath:com/liying/mapper/*.xml"/>     </bean>          <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">                  <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>                  <property name="basePackage" value="com.liying.dao"/>     </bean>          <bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">         <property name="dataSource" ref="dataSource"/>     </bean>          <tx:advice id="advice" transaction-manager="tx">         <tx:attributes>             <tx:method name="save*" propagation="REQUIRED" isolation="DEFAULT" read-only="false"/>             <tx:method name="remove*" propagation="REQUIRED" isolation="DEFAULT" read-only="false"/>             <tx:method name="update*" propagation="REQUIRED" isolation="DEFAULT" read-only="false"/>             <tx:method name="find*" propagation="SUPPORTS" isolation="DEFAULT" read-only="true"/>         </tx:attributes>     </tx:advice>          <aop:config proxy-target-class="true">         <aop:pointcut id="pc" expression="execution(* com.liying.service.impl.*.*(..))"/>         <aop:advisor advice-ref="advice" pointcut-ref="pc"/>     </aop:config> </beans>

6.web.xml 主配置文件

可配置： ①读取数据库（spring-mybatis） ②设置字符编码过滤器 ③springmvc上下文监听器 ④设置servlet，这样才能让程序读取spring-mvc.xml ⑤配置Session失效时间（默认半个小时） ⑥配置欢迎页面 ⑦配置错误页面
