Spring+SpringMvc+Mybatis框架集成搭建教程二(依赖配置及框架整合)

依赖导入以及框架整合

(1).打开项目的pom.xml文件，声明依赖

(2).在项目的resources文件夹下新建jdbc.properties文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.20.196:3306/dev?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456
jdbc.maxActive=30
jdbc.minIdle=5

(3).在项目的resources文件夹下新建log4j.properties文件

### set log levels ###log4j.rootLogger = ERROR ,  stdout , D , E , F

### 输出到控制台 ###log4j.appender.stdout = org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern =  %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %l-%t:%r ] - [ %X{ip} %X{userName}]  %m%n

## 输出到日志文件 ###log4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.DatePattern = ‘.‘yyyyMMddlog4j.appender.D.File = logs/wap/warn.loglog4j.appender.D.Append = truelog4j.appender.D.Threshold = WARNlog4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.encoding=UTF-8log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %l-%t:%r ] - [ %X{ip} %X{userName}]  %m%n

(4).在项目的resources文件夹下新建mapper、spring、mybatis三个文件夹分别用来存放mybatis的mapper xml文件以及spring的配置文件以及mybatis的配置文件。

(5).在项目的resources文件夹下的mybatis文件夹下新建mybatis.xml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>

    <!-- 全局配置setting,根据需要进行配置 -->
    <!--<settings>
        <setting name="" value=""/>
    </settings>-->

    <!-- 设置别名 -->
    <typeAliases>
        <!-- 批量进行设置别名 -->
        <package name="com.hafiz.www.po"/>
    </typeAliases>

    <!-- 使用自动扫描器时，mapper.xml文件如果和mapper.java接口在一个目录则此处不用定义mappers -->
    <!-- <mappers>

        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxActive" value="${jdbc.maxActive}"/>
        <property name="minIdle" value="${jdbc.minIdle}" />
    </bean>

    <!-- 配置sqlSessionFactory交由spring进行管理 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 设置数据源引用 -->
        <property name="dataSource" ref="dataSource"></property>

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>

</beans>

    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <!--配置组件扫描，只扫描Controller注解之外的组件-->
    <context:component-scan base-package="com.hafiz.www">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

</beans>

        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

        <!-- 事务管理器

         -->
         <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <!-- 配置视图解析器
        解析jsp视图，默认使用jstl标签，classpath下得有jstl包
     -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 配置jsp文件的前缀和后缀 -->
        <property name="prefix" value="/WEB-INF/jsp/"/>

    <!--配置注解控制器映射器-->
    <!--<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>-->

    <!-- 使用mvc:annotation-driven代替上边的 注解控制器适配器 和 注解控制器映射器 配置，
        mvc:annotation-driven默认加载了很多参数绑定方法，比如：
        json转换器就默认加载了，如果使用mvc:annotation-driven就不用再进行上面RequestMappingHandlerAdapter和RequestMappingHandlerMapping的配置
        实际开发过程中往往使用mvc:annotation-driven
    -->
    <!-- 扫描注解驱动，如:@Required, @Autowired, @PostConstruct, @PersistenceContext, @ Resource, @ PreDestroy.... -->
    <!--<context:annotation-config />-->

    <!-- 扫描mvc注解驱动，如：@RequestMapping, @Controller,@RequestBody,@ResponseBody.... -->

        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 配置全局异常处理器
        只要实现了HandlerExceptionResolver接口就是全局异常处理器类，每个系统只能有一个全局异常处理器类
     -->
     <!--<bean class="com.hafiz.www.exception.CustomExceptionResolver"/>-->

     <!-- 配置文件上传 -->
     <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 设置上传文件的最大尺寸为5MB -->

<web-app 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/j2ee
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">
  <display-name>pegasus-scm</display-name>

    <param-value>classpath:log4j.properties</param-value>
  </context-param>
  <!-- 60s 检测日志配置 文件变化 -->
  <context-param>
    <param-name>log4jRefreshInterval</param-name>
    <param-value>60000</param-value>
  </context-param>

  <!-- EncodingFilter -->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>

    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- listener -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
  </listener>
  <!-- 配置Log4j监听器 -->
  <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>

    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

(7).在webapp下面创建js、css、img三个文件夹分别用来存放网站的脚本文件、样式文件以及图片文件

至此，Spring、SpringMvc、Mybatis的整合完毕！
