配置pom.xml、spring.xml、spring-mvc.xml、spring-mybatis.xml、web.xml

原博客

（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="

    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd  
    http://www.springframework.org/schema/aop   
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd  
    ">  
      
        <!-- JNDI方式配置数据源 -->  
        <!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> -->

            <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->  
            <property name="minEvictableIdleTimeMillis" value="25200000" />  
      
            <!-- 打开removeAbandoned功能 -->  
            <property name="removeAbandoned" value="true" />  
            <!-- 1800秒，也就是30分钟 -->  
            <property name="removeAbandonedTimeout" value="1800" />  
            <!-- 关闭abanded连接时输出错误日志 -->  
            <property name="logAbandoned" value="true" />  
      
            <!-- 监控数据库 -->  
            <!-- <property name="filters" value="stat" /> -->  
            <property name="filters" value="mergeStat" />  
        </bean>  
      
        <!-- myBatis文件 -->  
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
            <property name="dataSource" ref="dataSource" />  
            <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->  
            <property name="mapperLocations" value="classpath:wqh/mapping/*.xml" />

            <property name="basePackage" value="wqh.dao" />  
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />  
        </bean>  
      
        <!-- 配置事务管理器 -->  
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
            <property name="dataSource" ref="dataSource" />

        <!-- 注解方式配置事物 -->  
        <!-- <tx:annotation-driven transaction-manager="transactionManager" /> -->  
      
        <!-- 拦截器方式配置事物 -->  
        <tx:advice id="transactionAdvice" transaction-manager="transactionManager">  
            <tx:attributes>  
                <tx:method name="add*" propagation="REQUIRED" />  
                <tx:method name="append*" propagation="REQUIRED" />  
                <tx:method name="insert*" propagation="REQUIRED" />  
                <tx:method name="save*" propagation="REQUIRED" />  
                <tx:method name="update*" propagation="REQUIRED" />  
                <tx:method name="modify*" propagation="REQUIRED" />  
                <tx:method name="edit*" propagation="REQUIRED" />  
                <tx:method name="delete*" propagation="REQUIRED" />  
                <tx:method name="remove*" propagation="REQUIRED" />  
                <tx:method name="repair" propagation="REQUIRED" />  
                <tx:method name="delAndRepair" propagation="REQUIRED" />  
      
                <tx:method name="get*" propagation="SUPPORTS" />  
                <tx:method name="find*" propagation="SUPPORTS" />  
                <tx:method name="load*" propagation="SUPPORTS" />  
                <tx:method name="search*" propagation="SUPPORTS" />  
                <tx:method name="datagrid*" propagation="SUPPORTS" />  
      
                <tx:method name="*" propagation="SUPPORTS" />  
            </tx:attributes>  
        </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srcmainwebappWEB-INFweb.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">
