Spring的一些配置

好用请点赞收藏一波!

转发请带上作者名@LLLua和原文地址,谢谢!


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。。。
