基于SSM的租赁管理系统1.0_20161225_框架搭建

搭建SSM底层框架

1. 利用mybatis反向工程generatorSqlmapCustom完成对数据库十表的映射

generatorConfig.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE generatorConfiguration
   PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
   "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

 <generatorConfiguration>
     <context id="testTables" targetRuntime="MyBatis3">
         <commentGenerator>
             <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
             <property name="suppressAllComments" value="true" />
         </commentGenerator>
         <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
         <jdbcConnection driverClass="com.mysql.jdbc.Driver"
             connectionURL="jdbc:mysql://localhost:3306/test" userId="root"
             password="root">
         </jdbcConnection>
         <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 和
             NUMERIC 类型解析为java.math.BigDecimal -->
         <javaTypeResolver>
             <property name="forceBigDecimals" value="false" />
         </javaTypeResolver>

         <!-- targetProject:生成PO类的位置 -->
         <javaModelGenerator targetPackage="org.guangsoft.po"
             targetProject=".\src">
             <!-- enableSubPackages:是否让schema作为包的后缀 -->
             <property name="enableSubPackages" value="false" />
             <!-- 从数据库返回的值被清理前后的空格 -->
             <property name="trimStrings" value="true" />
         </javaModelGenerator>
         <!-- targetProject:mapper映射文件生成的位置 -->
         <sqlMapGenerator targetPackage="mybatis"
             targetProject=".\src">
             <!-- enableSubPackages:是否让schema作为包的后缀 -->
             <property name="enableSubPackages" value="false" />
         </sqlMapGenerator>
         <!-- targetPackage：mapper接口生成的位置 -->
         <javaClientGenerator type="XMLMAPPER"
             targetPackage="org.guangsoft.mapper"
             targetProject=".\src">
             <!-- enableSubPackages:是否让schema作为包的后缀 -->
             <property name="enableSubPackages" value="false" />
         </javaClientGenerator>
         <!-- 指定数据库表 -->
         <table schema="" tableName="users"></table>
         <table schema="" tableName="roles"></table>
         <table schema="" tableName="privileges"></table>
         <table schema="" tableName="items"></table>
         <table schema="" tableName="cars"></table>
         <table schema="" tableName="clients"></table>
         <table schema="" tableName="loginlog"></table>
         <table schema="" tableName="systemlog"></table>
         <table schema="" tableName="rents"></table>
         <table schema="" tableName="checks"></table>
     </context>
 </generatorConfiguration>

2. 配置mybatis

SqlMapperConfig.xml

 <?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>
 <!-- 配置分页插件 -->
     <plugins>
         <plugin interceptor="com.github.pagehelper.PageHelper">
             <!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库-->
             <property name="dialect" value="mysql"/>
         </plugin>
     </plugins>
 </configuration>

3. 配置spring-dao

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root
