idea 基于maven 的ssm 整合实现登录功能（第一篇）

创建maven 的javeweb 项目

1. 打开idea New – Project 一路next 下去，输入项目的名字，model 名字，项目就创建好了.
   

项目创建完成后 针对项目做下简单的配置

File – Project Structure 或者快捷键 ctrl+alt +shift+s 打开项目配置
选中module 右侧选择 Sources 在src -main 下创建 java 文件夹(源码文件夹),选中创建的java 文件夹 选择 上方的 Sources 作用是把这个java 文件夹定位成 源码文件夹

导入需要的Spring SpringMvc MyBatis 的jar maven 构建

• 这里目前是这么多，后续可能继续添加

把相关的包给创建一下，后面的文件要用到

文件夹 说明一下 – test 是测试包 可以忽略

创建jdbc.properties 文件

在resources 文件夹下创建jdbc.properties 文件,内容如下

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password= 

需要创建spring 相关的xml 配置 文件

在资源文件夹(resources)中创建sping 文件夹 存放spring 相关的配置

1. spring-dao.xml 文件配置

<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"
       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">

    
    
    <context:property-placeholder location="classpath:jdbc.properties" />

    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        
        <property name="maxPoolSize" value="30" />
        <property name="minPoolSize" value="10" />
        
        <property name="autoCommitOnClose" value="false" />
        
        <property name="checkoutTimeout" value="10000" />
        
        <property name="acquireRetryAttempts" value="2" />
    bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        
        <property name="dataSource" ref="dataSource" />
        
        <property name="configLocation" value="classpath:mybatis-config.xml" />
        
        <property name="typeAliasesPackage" value="com.stevefat.entity" />
        
        <property name="mapperLocations" value="classpath:mapper/*.xml" /> 
    bean>

    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
        
        <property name="basePackage" value="com.stevefat.dao" />
    bean>

beans>

1. spring-service.xml 文件配置

<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:tx="http://www.springframework.org/schema/tx"
       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">

    
    <context:component-scan base-package="com.stevefat.service" />

    
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        
        <property name="dataSource" ref="dataSource" />
    bean>

    
    <tx:annotation-driven transaction-manager="transactionManager" />

beans>

1. spring-web.xml 文件配置

<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: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/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    
    
    
    <mvc:annotation-driven />

    
    <mvc:default-servlet-handler/>

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    bean>

    
    <context:component-scan base-package="com.stevefat.web" />

创建log4j 相关的xml 配置文件

这里因为我的是demo所以我没有配置，如需配置可以百度搜索一下

创建mybatis 相关的xml 配置文件

<configuration>
    
    <settings>
        
        <setting name="useGeneratedKeys" value="true" />

        
        <setting name="useColumnLabel" value="true" />

        
        <setting name="mapUnderscoreToCamelCase" value="true" />
    settings>
configuration>

修改web.xml 的配置文件

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1" metadata-complete="true">
    
    
    <servlet>
        <servlet-name>seckill-dispatcherservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:spring/spring-*.xmlparam-value>
        init-param>

        <url-pattern>/url-pattern>
    servlet-mapping>

web-app>

文件配置暂时结束，下一章节开始使用这些配置文件
