spring-session-redis共享的配置

2020-07-23 分类：优质文章 阅读(1005)

spring-session-redis共享的配置，为了复制方便特意做到这里。

一、 maven web项目的依赖

pom.xml中添加properties

    <properties>
        <!-- 文件拷贝时的编码 -->
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <!-- 编译时的编码 -->
        <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
        <!-- spring版本号 -->
        <spring.version>4.3.10.RELEASE</spring.version>
    </properties>

pom.xml添加web项目和spring的依赖

        <!-- servlet -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>

        </dependency>

        <!-- spring-mvc -->
        <dependency>

            <artifactId>spring-web</artifactId>

        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>

        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <!-- spring-orm -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-orm</artifactId>
            <version>${spring.version}</version>

            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
        </dependency>

pom.xml添加spring-session-redis的依赖

        <!-- spring-session-data-redis -->
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
            <version>1.3.1.RELEASE</version>
        </dependency>

二、 修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee" xmlns:web="http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee">

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <listener>
      <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>

    <filter>
        <filter-name>springSessionRepositoryFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>springSessionRepositoryFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

    <session-config>
        <session-timeout>2</session-timeout>
    </session-config>

</web-app>

在web.xml中添加了spring的配置，spring-mvc的配置，已经ContLoaderListener和RequestContextListener的监听。

附带提下ContextLoaderListener与RequestContextListener的区别

ContextLoaderListener extends ContextLoader implements ServletContextListener
RequestContextListener implements ServletRequestListener

ServletContextListener extends EventListener。
ServletContextListener只负责监听Web容器的启动和关闭的事件。
ContextLoaderListener(或ContextLoaderServlet)将Web容器与spring容器进行整合。

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener> 

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext.xml</param-value>
</context-param>

如果没有显式声明，则 系统默认 在WEB-INF/applicationContext.xml，多个文件可以使用逗号分开。

ServletRequestListener extends EventListener。
ServletRequestListener监听HTTP请求事件，Web服务器接收的每次请求都会通知该监听器。
RequestContextListener将Spring容器与Web容器结合的更加密切。这是可选配置，并且后者与scope=”request”搭配使用。

<listener>
  <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

三、 配置下applicationContext.xml和springmvc-servlet.xml

applicationContext.xml配置


    <!-- spring 扫描基础包，但最好不扫描controller的包 -->
    <context:component-scan base-package="com.imddy.tsession">
        <!-- <context:exclude-filter> -->
        <!-- 指定不扫描的 -->
        <!-- <context:include-filter> -->
        <!-- 指定需要扫描的 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> 
    </context:component-scan>

    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="30" />
        <property name="maxIdle" value="10" />
        <property name="minIdle" value="1" />
        <property name="maxWaitMillis" value="30000" />
        <property name="testOnBorrow" value="true" />
        <property name="testOnReturn" value="false" />
        <property name="testWhileIdle" value="false" />
    </bean>

    <context:annotation-config />

    <bean id="redisHttpSessionConfiguration"
        class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <property name="maxInactiveIntervalInSeconds" value="600" />
    </bean>

    <bean id="jedisConnectionFactory"
        class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        destroy-method="destroy">
        <property name="hostName" value="127.0.0.1" />
        <property name="port" value="6379" />
        <property name="timeout" value="3000" />
        <property name="usePool" value="true" />
        <property name="poolConfig" ref="jedisPoolConfig" />
    </bean>

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory" />
    </bean>

springmvc-serlvet.xml配置

    <!-- spring-mvc 扫描controller的包 -->
    <context:component-scan base-package="com.imddy.tsession.controller" />

    <!-- 这个要放在扫描的后面  -->
    <!-- spring-mvc 驱动注解 -->
    <mvc:annotation-driven />

    <!-- 启用spring mvc 注解 -->
    <context:annotation-config />

    <!-- 静态资源 -->
    <mvc:resources mapping="/js/**" location="/js/" />
    <mvc:resources mapping="/css/**" location="/css/" />
    <mvc:resources mapping="/images/**" location="/images/" />
    <mvc:resources mapping="/jslib/**" location="/jslib/" />

    <!-- spring-mvc 解析器的配置 -->
    <!-- ViewResolver -->  
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <!-- <property name="prefix" value="/WEB-INF/jsp/"/> -->
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 开启默认处理 -->
    <!-- 这样静态资源就可以访问了 -->
    <mvc:default-servlet-handler />

<!--    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
        <property name="defaultEncoding" value="utf-8"></property>   
        <property name="maxUploadSize" value="10485760000"></property>  
        <property name="maxInMemorySize" value="40960"></property>  
    </bean> -->

log4j的配置就不贴了。

四、 测试对应的controller和jsp页面

login.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<link href="./jslib/bootstrap/css/bootstrap-theme.min.css" rel="stylesheet">
<link href="./jslib/bootstrap/css/bootstrap.min.css" rel="stylesheet">

<script src="./jslib/jquery/1.12.4/jquery.min.js"></script>
<script src="./jslib/bootstrap/js/bootstrap.min.js"></script>

<script type="text/javascript">

</script>

<title>login.jsp</title>
</head>
<body>

    <form role="form" action="loginPost.do">
        <input type="text" name="username" class="form-control" placeholder="请输入用户名" required autofocus>
        <input type="password" name="password" class="form-control" placeholder="请输入密码" required>
        <button class="btn btn-lg btn-primary btn-block" type="submit">登陆</button>
    </form>

</body>
</html>

sessioninfo.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<link href="https://cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap-theme.min.css" rel="stylesheet">
<link href="https://cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet">

<script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

<script type="text/javascript">

</script>

<title>sessioninfo.jsp</title>
</head>
<body>

    <%String s = session.getId(); //获取session ID号  %>
    <%=s %>

    <%String username = (String)session.getAttribute("username"); //获取session ID号  %>
    <br/>
    <%=username %>

</body>
</html>

TestController

package com.imddy.tsession.controller;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class TestController {

    private static Log log = LogFactory.getLog(TestController.class);

    @RequestMapping("/loginGet")
    public String loginGet(){
        log.info("do loginGet ...");
        return "/login";
    }

    @RequestMapping("/loginPost")
    public String loginPost(HttpServletRequest request){
        log.info("do loginPost ...");
        String username = request.getParameter("username");
        request.getSession().setAttribute("username", username);
        return "redirect:/sessioninfo.do";
    }

    @RequestMapping("/sessioninfo")
    public String sessioninfo(){
        return "/sessioninfo";
    }

}

测试到2个不通的tomcat中一个端口是8080,另一个端口是8090，测试结果如下图：
