使用ssm框架编写简单图书管理系统（一）
1.创建项目 编写配置文件
可参考上一篇文章 https://blog.csdn.net/xyz1995920/article/details/79901324
贴上配置文件：
1、pom.xml：
xml version="1.0" encoding="UTF-8"?>
xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
2、web.xml:
xml version="1.0" encoding="UTF-8"?>
version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
3、applicationContext.xml （spring配置文件）
xml version="1.0" encoding="UTF-8"?>
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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

">
<context:property-placeholder location="classpath:jdbc.properties"/>
<context:annotation-config/>
<context:component-scan base-package="cn.vp">

context:component-scan>

name="maxWait" value="5000"/>
id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

name="mapperLocations" value="classpath:cn/vp/dao/*.xml"/>
name="typeAliasesPackage" value="cn.vp"/>
class="org.mybatis.spring.mapper.MapperScannerConfigurer">

name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
name="dataSource" ref="druidDataSource"/>
<tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>
4、springmvc-servlet.xml（springmvc配置文件）
xml version="1.0" encoding="UTF-8"?>
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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="cn.vp.controller">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>
<mvc:annotation-driven conversion-service="formattingConversionServiceFactoryBean"/>
<mvc:resources location="/images/" mapping="/images/**"/>
id="formattingConversionServiceFactoryBean"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
name="converters">
id="dateConverter" class="cn.vp.controller.DateConverter"/>
id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
name="prefix" value="/WEB-INF/jsp/"/>
name="suffix" value=".jsp"/>
name="viewClass"
value="org.springframework.web.servlet.view.JstlView"/>
id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" >
name="defaultEncoding" value="utf-8"/>
name="maxInMemorySize" value="10240"/>
name="uploadTempDir" value="/images/"/>
name="maxUploadSize" value="-1"/>
<mvc:resources location="/images/" mapping="/images/**" />
<mvc:resources location="/js/" mapping="/js/**"/>
5、generatorconfig.xml（自动生成javabean和dao）
xml version="1.0" encoding="UTF-8"?>
generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://www.mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
resource="jdbc.properties"/>
location="H:\Maven\LocalWarehouse\mysql\mysql-connector-java\5.1.6\mysql-connector-java-5.1.6.jar" />
id="DB2Tables" targetRuntime="MyBatis3">
type="org.mybatis.generator.plugins.SerializablePlugin"/>
name="suppressDate" value="true" />
name="suppressAllComments" value="true" />
driverClass="${driver}"
connectionURL="${url}" userId="${username}" password="${password}">
name="forceBigDecimals" value="false" />
targetPackage="cn.vp.bean"
targetProject="src/main/java">
name="enableSubPackages" value="true" />
name="trimStrings" value="true" />
targetPackage="cn.vp.dao"
targetProject="src/main/java">
name="enableSubPackages" value="true" />
type="XMLMAPPER"
targetPackage="cn.vp.dao" targetProject="src/main/java">
name="enableSubPackages" value="true" />
tableName="book_info"
domainObjectName="BookInfo"
enableCountByExample="false"
enableUpdateByExample="false"
enableDeleteByExample="false"
enableSelectByExample="false"
selectByExampleQueryId="false"/>
tableName="book_type" domainObjectName="BookType"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false"/>
6、jdbc.properties和log4j.properties
2. 生成代码并修改
1.配置generator
2.配置tomcat
3.生成代码
4.根据需求修改实体类代码
在BookInfoMapper类加上查询所有图书的方法
在对应的xml里面加上sql语句 并修改上面因为实体类变化要改的代码
xml version="1.0" encoding="UTF-8"?>

到目前为止框架大致搭完
