2.配置web.xml

这里主要配置了:编码过滤器，spring配置监听器，springMVC的dispatcherServlet的配置,log4j

log4j.properties

 

 ### set log levels ### 

log4j.rootLogger = debug,stdout,D,E 

 

log4j.appender.stdout = org.apache.log4j.ConsoleAppender 

log4j.appender.stdout.Target = System.out 

log4j.appender.stdout.layout = org.apache.log4j.PatternLayout 

log4j.appender.stdout.layout.ConversionPattern = [%-5p]%d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n 

 

log4j.appender.D = org.apache.log4j.DailyRollingFileAppender 

log4j.appender.D.File = H://logs/log.log 

log4j.appender.D.Append = true 

log4j.appender.D.Threshold = DEBUG  

log4j.appender.D.layout = org.apache.log4j.PatternLayout 

log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-ddHH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n 

 

log4j.appender.E = org.apache.log4j.DailyRollingFileAppender 

log4j.appender.E.File =H://logs/error.log  

log4j.appender.E.Append = true 

log4j.appender.E.Threshold = ERROR  

log4j.appender.E.layout = org.apache.log4j.PatternLayout 

log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-ddHH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

3.配置spring

思路：1.先配数据源datasource

             2.配置工厂sqlSessionFactory

 3.配置事务管理器dataSourceTransactionManager

 4.配置事务属性通知txAdvice

 5.配置事务切入点 pointcut

 6.配置注解支持

 

例：

db.properties

 

driver=com.mysql.jdbc.Driver

url=jdbc:mysql:///test

name=root

password=wxniit

 

----------------------------------------------------------------------------------------------------

<!--读取属性文件 -->

<!--<context:property-placeholderlocation="classpath:db.properties"/>  -->

<beanid="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<propertyname="location">

          <value>classpath:db.properties</value>

</property>

</bean>

 

<!--配置datasource -->

<beanid="datasource"class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<propertyname="driverClassName"value="${driver}"></property>

<propertyname="url" value="${url}"></property>

<propertyname="username" value="${name}"></property>

<propertyname="password" value="${password}"></property>

</bean>

 

<!--配置工厂 -->

<beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean">

<propertyname="dataSource" ref="datasource"></property>

<propertyname="configLocation"value="classpath:mybatis-cfg.xml"></property>

</bean>

 

<!--配置声明式事务  -->

<!--事务管理器 -->

<beanid="txManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<propertyname="dataSource" ref="datasource"></property>

</bean>

<!--事务声明通知 -->

<tx:adviceid="txAdvice" transaction-manager="txManager">

<tx:attributes>

<tx:methodname="save" propagation="REQUIRED"/>

<tx:methodname="get" read-only="true"/>

<tx:methodname="*" propagation="REQUIRED"/>

</tx:attributes>

</tx:advice>

<aop:config>

<aop:pointcut expression="execution(* com.chenj.app.serivce.impl.*.*(..))"id="pointcut"/>

<aop:advisoradvice-ref="txAdvice" pointcut-ref="pointcut"/>

</aop:config>

 

<!--扫描controller -->

<context:component-scanbase-package="com.chenj.app"></context:component-scan>

 

4.配置springMVC

这里主要配置了 json，文件上传，视图解析，注解支持，拦截器（需要实现org.springframework.web.servlet.HandlerInterceptor）

例：

<!--启动Springmvc注解驱动 -->

<mvc:annotation-driven/>

<!--返回json方法一需要导入 fastjson.jar包-->

<!--<mvc:annotation-driven> <mvc:message-convertersregister-defaults="false">

避免IE执行AJAX时,返回JSON出现下载文件 <bean id="fastJsonHttpMessageConverter"class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">

<propertyname="supportedMediaTypes"> <list>这里顺序不能反，一定先写text/html,不然ie下出现下载提示

<value>text/html;charset=UTF-8</value><value>application/json;charset=UTF-8</value>

</list></property> </bean> </mvc:message-converters></mvc:annotation-driven> -->

 

 

<!--返回json方法二需要导入jackson-annotations.jar,jackson-core.jar,jackson-databind.jar -->

<bean

class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>

<bean

class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">

<propertyname="messageConverters">

<list>

<bean

class="org.springframework.http.converter.StringHttpMessageConverter">

<propertyname="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

<value>application/json;charset=UTF-8</value>

</list>

</property>

</bean>

<bean

class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

<propertyname="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

<value>application/json;charset=UTF-8</value>

</list>

</property>

</bean>

</list>

</property>

</bean>

 

<!--拦截器配置 -->

<!--<mvc:interceptors> <mvc:interceptor> <mvc:mappingpath="/**"/> <bean

class="com.chenj.app.interceptor.LoginInterceptor"><property name="allowedPass">

<list><value>login.do</value> </list> </property></bean> </mvc:interceptor>

</mvc:interceptors>-->

 

<!--文件上传配置 -->

<beanid="multipartResolver"

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<propertyname="defaultEncoding" value="utf-8"></property>

<propertyname="maxUploadSize"value="10485760000"></property>

<propertyname="maxInMemorySize" value="40960"></property>

</bean>

 

<!--配置视图解析器 -->

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<!--<property name="viewClass"value="org.springframework.web.servlet.view.JstlView"></property>-->

<propertyname="prefix" value="/WEB-INF/pages/" />

<propertyname="suffix" value=".jsp" />

</bean>

 

<!--配置注解支持-->

<context:component-scanbase-package="com.chenj.app"></context:component-scan>

 

5.配置mybatis

注：需要在spring配置工厂时加上<property name="configLocation"value="classpath:mybatis-cfg.xml"></property>

 

例：

<?xmlversion="1.0" encoding="UTF-8"?>

<!DOCTYPEconfiguration SYSTEM "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

<typeAliases>

   <packagename="com.chenj.app.entity"/>

</typeAliases>

<!--配置mapper的位置-->

<mappers>

<mapperresource="com/chenj/app/entity/userMapper.xml"/>

</mappers>

</configuration>
