spring官网或github找到官方示例,照着拷到自己的工程里来。
在web.xml中了解过滤器的配置
有些了解作用就好,如
CharacterEncodingFilter,就是转字符集用的
有些可以详细了解,如
RequestContextListener(web容器启动关闭事件监听器)
ContextLoaderListener(web容器和spring整合)
DispatcherServlet(servlet拦截器)
在其上按下ctrl键就能看到源码
接下来看applicationContext.xml,本体比较简略,只有个自动扫包和aop
但是引入了2个xml,看来大头在那两个import里。
<?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:jdbc="http://www.springframework.org/schema/jdbc" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> <context:component-scan base-package="com.my" annotation-config="true"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <aop:aspectj-autoproxy/> <import resource="applicationContext-spring-session.xml"/> <import resource="applicationContext-datasource.xml"/> </beans>
打开applicationContext-spring-session.xml
因为要连接redis,并做redis分布式,用了jedis,并做了一些配置。
<?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:jdbc="http://www.springframework.org/schema/jdbc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"> <property name="maxInactiveIntervalInSeconds" value="1800" /> </bean> <bean id="defaultCookieSerializer" class="org.springframework.session.web.http.DefaultCookieSerializer"> <property name="domainName" value=".xxx.com" /> <property name="useHttpOnlyCookie" value="true" /> <property name="cookiePath" value="/" /> <property name="cookieMaxAge" value="31536000" /> </bean> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxTotal" value="20"/> </bean> <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"> <property name="hostName" value="127.0.0.1" /> <property name="port" value="6379" /> <property name="poolConfig" ref="jedisPoolConfig" /> </bean> </beans>
再看applicationContext-datasource.xml
实际设置的值在datasource.properties中
写的这么详细了,相信以后的自己和可能会有的读者也一定看的懂。。。
