(1)修改pom.xml文件,引入jar包

        </build>  
    </project>  

修改完保存该文件是会去自动下载spring、mybatis、json、jdbc等相关jar包,需要保持联网状态。

(2)在src/main/resources文件夹下面新建config.properties文件,内容如下

[plain] view plain copy

    #hibernate.dialect=org.hibernate.dialect.OracleDialect  
    #driverClassName=oracle.jdbc.driver.OracleDriver  
    #validationQuery=SELECT 1 FROM DUAL  
    #jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl  
    #jdbc_username=wqhpro  
    #jdbc_password=wqhpro  
      
    hibernate.dialect=org.hibernate.dialect.MySQLDialect  
    driverClassName=com.mysql.jdbc.Driver  
    validationQuery=SELECT 1  
    jdbc_url=jdbc:mysql://localhost:3306/wqh?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull  
    jdbc_username=root  
    jdbc_password=root  
      
    #hibernate.dialect=org.hibernate.dialect.SQLServerDialect  
    #driverClassName=net.sourceforge.jtds.jdbc.Driver  
    #validationQuery=SELECT 1  
    #jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/wqh  
    #jdbc_username=sa  
    #jdbc_password=123456  
      
    #hibernate.dialect=org.hibernate.dialect.DerbyDialect  
    #driverClassName=org.apache.derby.jdbc.EmbeddedDriver  
    #validationQuery=SELECT 1  
    #jdbc_url=jdbc:derby:sy;create=true  
    #jdbc_username=wqhpro  
    #jdbc_password=wqhpro  
      
    #jndiName=java:comp/env/dataSourceName  
      
    hibernate.hbm2ddl.auto=update  
    hibernate.show_sql=false  
    hibernate.format_sql=true  
      
    sessionInfoName=sessionInfo  
      
    uploadFieldName=filedata  
    uploadFileMaxSize=20971520  
    uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid  
    uploadDirectory=attached  

 该文件配置了,连接数据库的地址、用户名、密码等信息。

(3)在src/main/resources文件夹下面新建spring.xml文件,内容如下

[html] view plain copy

    <?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="  
    http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.0.xsd  
    ">  
      
        <!-- 引入属性文件 -->  
        <context:property-placeholder location="classpath:config.properties" />  
      
        <!-- 自动扫描(自动注入) -->  
        <context:component-scan base-package="wqh.service" />  
      
      
    </beans>  

 spring配置,引入数据库相关的配置文件和自动扫描并注入wqh.service包下面的添加注解的类。

(4)在src/main/resources文件夹下面新建spring-mybatis.xml文件,内容如下

[html] view plain copy

    <?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="

                <tx:method name="add*" propagation="REQUIRED" />  
                <tx:method name="append*" propagation="REQUIRED" />

                <tx:method name="datagrid*" propagation="SUPPORTS" />  
      
                <tx:method name="*" propagation="SUPPORTS" />

        </tx:advice>  
        <aop:config>  
            <aop:pointcut id="transactionPointcut" expression="execution(* wqh.service..*Impl.*(..))" />  
            <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" />  
        </aop:config>  
      

注意:expression="execution(* com.test.testAda.test.model.service.*.*(..))"
       其中第一个*代表返回值,第二*代表service下子包,第三个*代表方法名,“(..)”代表方法参数。
      
        <!-- 配置druid监控spring jdbc -->  
        <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor">  
        </bean>  
        <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype">  
            <property name="patterns">  
                <list>  
                    <value>wqh.service.*</value>  
                </list>  
            </property>  
        </bean>  
        <aop:config>  
            <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />  
        </aop:config>  
      
    </beans>  

 该文件的相关配置:配置了数据源的bean,即使用阿里巴巴开发的DruidDataSource数据源,配置了一个名叫dataSource的bean;配置myBatis的SqlSessionFactoryBean的bean,为其指明dataSource属性值为上面配的名叫dataSource的bean,mapperLocations属性值为Mapper.xml文件的路径;

配置mybatis的MapperScannerConfigurer类的相关属性值,basePackage属性代表Mapper.xml的namespace所指的java接口的文件路径,sqlSessionFactoryBeanName属性代表了该MapperScannerConfigurer使用哪个SqlSessionFactoryBean;剩下的配置就是使用切面式的方式配置了事务管理。

(5)在src/main/resources文件夹下面新建spring-mvc.xml文件,内容如下

[html] view plain copy

    <?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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" xsi:schemaLocation="http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
    http://www.springframework.org/schema/context   
    http://www.springframework.org/schema/context/spring-context-3.0.xsd   
    http://www.springframework.org/schema/mvc   
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">  
      
        <!-- 自动扫描controller包下的所有类,使其认为spring mvc的控制器 -->  
        <context:component-scan base-package="wqh.controller" />  
      
        <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->  
        <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
            <property name="supportedMediaTypes">  
                <list>  
                    <value>text/html;charset=UTF-8</value>  
                </list>  
            </property>  
        </bean>  
      
        <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 -->  
        <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  
            <property name="messageConverters">  
                <list>  
                    <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->  
                </list>  
            </property>  
        </bean>  
      
        <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 -->  
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" />  
      
        <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
            <property name="defaultEncoding">  
                <value>UTF-8</value>  
            </property>  
            <property name="maxUploadSize">  
                <value>32505856</value><!-- 上传文件大小限制为31M,31*1024*1024 -->  
            </property>  
            <property name="maxInMemorySize">  
                <value>4096</value>  
            </property>  
        </bean>  
      
    </beans>  

 该文件内容比较少就不讲解了,直接看注释吧。

(6)在src\main\webapp\WEB-INF\web.xml文件,内容如下
[html] view plain copy

    <?xml version="1.0" encoding="UTF-8"?>  
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

到现在已经配置完成下一篇进行测试吧。
