1.創建基本項目結構
Idea會自動開始下載所依賴的包,等待其完成。
創建完後的項目結構(沒有的文件夾可以自己創建):
2.修改pom.xml
因爲使用Maven管理項目,所以可以通過直接在pom.xml中配置來直接引入對應的包和管理對應的包

3.Spring-MVC配置:
配置springmvc,使用註解的方式來提高開發效率,讓程序員能夠更關注於業務的實現而不是重複枯燥的配置操作。

4.Spring-Mybatis配置
通過mybatis的配置,簡化所有的數據庫操作,只需要寫基本的sql語句就可以通過配置來操作對應的數據庫。
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<!-- 基本屬性 url、user、password -->
<property name="url"
value="jdbc:mysql://localhost/icekredit_platform?useUnicode=true&characterEncoding=utf-8"/>
<property name="username" value="root"/>
<property name="password" value="ICK64-mysql"/>
<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="1"/>
<property name="minIdle" value="1"/>
<property name="maxActive" value="20"/>
<!-- 配置獲取連接等待超時的時間 -->
<property name="maxWait" value="60000"/>
<!-- 配置間隔多久才進行一次檢測,檢測需要關閉的空閒連接,單位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000"/>
<!-- 配置一個連接在池中最小生存的時間,單位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000"/>
<property name="validationQuery" value="SELECT 'x'"/>
<property name="testWhileIdle" value="true"/>
<property name="testOnBorrow" value="false"/>
<property name="testOnReturn" value="false"/>
<!-- 打開PSCache,並且指定每個連接上PSCache的大小 -->
<property name="poolPreparedStatements" value="true"/>
<property name="maxPoolPreparedStatementPerConnectionSize"
value="20"/>
<!-- 配置監控統計攔截的filters -->
<property name="filters" value="stat"/>
</bean>
<!-- spring和MyBatis整合,不需要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<!-- 自動掃描mapping.xml文件 -->
<property name="mapperLocations" value="classpath*:com/icekredit/credit/mapper/xml/*.xml"></property>
</bean>
<!-- DAO接口所在包名,Spring會自動查找其下的類 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.icekredit.credit.mapper"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>

至此,一個ssm項目的框架就建立好了。隨着框架的增多,技術的發展,就基本的開發來說是越來越智能,越來越方便了。但是這並不代表寫程序就很簡單,除了實現基本的業務邏輯以爲,程序員應該在項目中更加關注高併發,高性能的實現。
