SSM框架搭建（配置文件篇）

一. 增加项目依赖

修改pom.xml增加SpringMVC Spring Mybatis相关项目依赖

                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.7</source>

                    <version>2.1</version>
                    <configuration>
                        <!-- 通过maven tomcat7:run运行项目时，访问项目的端口号 -->
                        <port>80</port>

                        <uriEncoding>UTF-8</uriEncoding>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

二. 分类建立配置文件目录

在resources文件目录下建立两个子目录spring和mapper用于存放spring的各个模块配置以及mybatis的mapper文件。这一步你也可以省略，只是以后配置文件显得比较杂乱。建立项目总控文件applicationContext.xml

<?xml version="1.0"encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    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/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd"
        default-autowire="byName">
    <!-- 注册组件扫描器 -->
    <context:component-scan base-package="com.pz.web.study.ssm.*"></context:component-scan>
    <bean id="propertyConfigurer"
              class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="ignoreUnresolvablePlaceholders" value="true" />
        <property name="locations">
            <list>
                <value>classpath:db.properties</value>
            </list>
        </property>
    </bean>
    <import resource="spring/spring-mybatis.xml"/>
    <import resource="spring/spring-service.xml"/>
    <import resource="spring/spring-tx.xml"/>
    <import resource="spring/spring-mvc.xml"/>
</beans>

三. 指定配置web.xml

<?xml version="1.0"encoding="UTF-8"?>
<web-app version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>order-center</display-name>
    <!-- 配置字符编码处理Filter-->
    <filter>
        <filter-name>EncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>EncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- 配置SpringMVC前端控制器 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:ApplicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

四. 配置mybatis总控文件

<?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>
    <typeAliases>
        <typeAlias type="com.pz.web.study.ssm.domain.TravelRoute" alias="TravelRoute" />
    </typeAliases>
    <mappers>
        <!--注册映射文件 -->
        <mapper resource="mapper/TravelRouteMapper.xml"/>
    </mappers>
</configuration>

五. 配置spring整合mybatis的文件

spring-mybatis.xml

<?xml version="1.0"encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    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/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd"
        default-autowire="byName">
    <!-- 数据库连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
          destroy-method="close">
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <!-- 配置初始化大小、最小、最大 -->
        <property name="initialSize" value="5" />
        <property name="minIdle" value="5" />
        <property name="maxActive" value="20" />
        <!-- 配置获取连接等待超时的时间 -->
        <property name="maxWait" value="3000" />
        <property name="useUnfairLock" value="true" />
        <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
        <property name="timeBetweenEvictionRunsMillis" value="5000" />
        <!--最小空闲时间 jed同事建议30s -->
        <property name="minEvictableIdleTimeMillis" value="30000" />
        <property name="validationQuery" value="SELECT 1" />
        <property name="testWhileIdle" value="true" />
        <property name="testOnBorrow" value="false" />
        <property name="testOnReturn" value="false" />
        <!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
        <property name="poolPreparedStatements"value="false" />
        <property name="maxPoolPreparedStatementPerConnectionSize"
                     value="0"/>
    </bean>
    <!-- 让spring管理sqlsessionfactory使用mybatis和spring整合包中的 -->
    <bean id="mybatiSqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 加载mybatis的全局配置文件 -->
        <property name="configLocation" value="classpath:mybatis.xml" />
    </bean>
    <!-- 自动扫描 将Mapper接口生成代理对象 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="mybatiSqlSessionFactory"/>
        <property name="basePackage" value="com.pz.web.study.ssm.dao" />
    </bean>
</beans>

六. 配置spring-mvc相关文件

spring-mvc.xml

<?xml version="1.0"encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"

        <property name="resolveLazily" value="true" />
    </bean>
    <mvc:default-servlet-handler />
</beans>

七. 配置service层相关文件

spring-service.xml

<?xml version="1.0"encoding="UTF-8"?>
