Redis搭建：Maven+Spring+SpringMVC+Redis

ookkl

一、搭建Redis环境 3.2.1
Redis gitHub 下载地址

下载之后直接解压得到以下目录结构

点击redis-server.exe即可启动Redis数据库

输出信息：启动成功、端口号、pid 即启动成功。

二、搭建开发环境
1>搭建springmvc支持

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

<!-- 搭建springmvc -->     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-webmvc</artifactId>         <version>4.3.4.RELEASE</version>     </dependency>         <dependency>         <groupId>javax.servlet</groupId>         <artifactId>javax.servlet-api</artifactId>         <version>3.1.0</version>     </dependency>     <dependency>         <groupId>com.fasterxml.jackson.core</groupId>         <artifactId>jackson-core</artifactId>         <version>2.8.4</version>     </dependency>     <dependency>         <groupId>com.fasterxml.jackson.core</groupId>         <artifactId>jackson-databind</artifactId>         <version>2.8.4</version>     </dependency>

2>集成Redis

1 2 3 4 5 6 7 8 9 10 11 12

<!-- 集成Redis -->     <dependency>         <groupId>org.springframework.data</groupId>         <artifactId>spring-data-redis</artifactId>         <version>1.7.5.RELEASE</version>     </dependency>     <!-- Redis客户端 -->     <dependency>         <groupId>redis.clients</groupId>         <artifactId>jedis</artifactId>         <version>2.9.0</version>     </dependency>

3>配置Redis:spring-redis.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

<?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.xsd         http://www.springframework.org/schema/context http://www.springframework.org/s ... ing-context-4.3.xsd">     <!-- 引入redis配置 -->     <context:property-placeholder location="classpath:redis.properties" ignore-unresolvable="true"/>     <!-- Redis 配置 -->     <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">         <property name="maxTotal" value="${redis.pool.maxTotal}" />         <property name="maxIdle" value="${redis.pool.maxIdle}" />         <property name="maxWaitMillis" value="${redis.pool.maxWaitMillis}" />         <property name="testOnBorrow" value="${redis.pool.testOnBorrow}" />     </bean>     <!-- redis单节点数据库连接配置 -->     <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">         <property name="hostName" value="${redis.ip}" />         <property name="port" value="${redis.port}" />         <!-- <property name="password" value="${redis.pass}" /> -->         <property name="poolConfig" ref="jedisPoolConfig" />     </bean>     <!-- redisTemplate配置，redisTemplate是对Jedis的对redis操作的扩展，有更多的操作，封装使操作更便捷 -->     <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">         <property name="connectionFactory" ref="jedisConnectionFactory" />     </bean> </beans>

4>配置redis.properties

1 2 3 4 5 6

redis.pool.maxTotal=105 redis.pool.maxIdle=10 redis.pool.maxWaitMillis=5000 redis.pool.testOnBorrow=true redis.ip=127.0.0.1 redis.port=6379

三、配置Servlet
此处不在web.xml中配置，采取硬编码方式

1.DispatchServlet拦截器

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

package com.redis.init; import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; /** * 配置拦截器 * @author hc * */ public class DispatcherServletInit extends AbstractAnnotationConfigDispatcherServletInitializer{     /**      * 配置应用上下文      */     @Override     protected Class<?>[] getRootConfigClasses() {         return new Class<?>[]{RootConfig.class};     }     /**      * 配置web上下文      */     @Override     protected Class<?>[] getServletConfigClasses() {         return new Class<?>[]{WebConfig.class};     }     @Override     protected String[] getServletMappings() {         return new String[]{"/"};     } }

2.应用上下文WebConfig

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

package com.redis.init; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.FilterType; import org.springframework.context.annotation.ImportResource; import org.springframework.context.annotation.ComponentScan.Filter; import org.springframework.stereotype.Controller; import org.springframework.web.servlet.config.annotation.EnableWebMvc; /** * 应用上下文 * @author hc * */ @Configuration @ComponentScan(basePackages={"com.redit"},excludeFilters={         @Filter(type=FilterType.ANNOTATION,value=Controller.class),         @Filter(type=FilterType.ANNOTATION,value=EnableWebMvc.class) }) @ImportResource("classpath:spring-*.xml")//引入redis配置文件 public class RootConfig { }

3.web上下文

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

package com.redis.init; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import org.springframework.web.servlet.view.InternalResourceViewResolver; @Configuration @EnableWebMvc @ComponentScan({"com.web"}) public class WebConfig extends WebMvcConfigurerAdapter{     /**      * 配置视图解析器      * @return      */     @Bean     public ViewResolver viewResolver(){         InternalResourceViewResolver resolver = new InternalResourceViewResolver();         resolver.setPrefix("/WEB-INF/views/");         resolver.setSuffix(".html");         resolver.setExposePathVariables(true);         return resolver;     }           /**      * 配置静态资源管理器      */     @Override     public void configureDefaultServletHandling(             DefaultServletHandlerConfigurer configurer) {         super.configureDefaultServletHandling(configurer);         configurer.enable();     } }

4.Controller

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

package com.redis.web; import java.util.List; import javax.annotation.Resource; import org.springframework.data.redis.core.ListOperations; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller @RequestMapping("user") public class UserController {     @Resource(name="redisTemplate")     private ListOperations<String, String[]> listUser;           @RequestMapping("/list")     @ResponseBody     public List<String[]> list(){         List<String[]> list=listUser.range("user", 0, -1);         return list;     }           @RequestMapping("/add")     @ResponseBody     public void add(String... user){         listUser.leftPush("user", user);     } }

基本配置完毕，待测试

四、使用Jedis客户端来测试
1.启动redis服务器

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<dependency>         <groupId>redis.clients</groupId>         <artifactId>jedis</artifactId>         <version>2.7.2</version>     </dependency>     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-test</artifactId>         <version>2.5</version>         <scope>test</scope>     </dependency>     <dependency>       <groupId>junit</groupId>       <artifactId>junit</artifactId>       <version>4.4</version>       <scope>test</scope>     </dependency>

junit尽量用高版本的，不然测试的时候会有版本冲突
2.配置参数

1 2 3 4 5 6 7 8 9 10 11 12 13

<!-- 配置Jedis链接服务器参数 -->     <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">         <property name="maxTotal" value="4096"/>         <property name="maxIdle" value="200"/>         <property name="maxWaitMillis" value="3000"/>         <property name="testOnBorrow" value="true" />         <property name="testOnReturn" value="true" />     </bean>     <bean id="jedisPool" class="redis.clients.jedis.JedisPool">         <constructor-arg index="0" ref="poolConfig"/>         <constructor-arg index="1" value="127.0.0.1"/>         <constructor-arg index="2" value="6379" type="int"/>     </bean>

3.测试

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

package redis_demo; import org.junit.Assert; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; /** * 使用Jedis来测试redis * @author hc * */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring-redis.xml") public class RedisTestByJedis extends AbstractJUnit4SpringContextTests{     @Autowired     private JedisPool jedisPool;           @Test     public void basicTest(){         Jedis jedis = jedisPool.getResource();         //存值         jedis.set("user.name", "aaa");         jedis.set("user.pass", "123");                   //取值         String name = jedis.get("user.name");         String pass = jedis.get("user.pass");         //断言         Assert.assertEquals("aaa", name);         //Assert.assertEquals("1234", pass);//错误         Assert.assertEquals("123", pass);                   jedis.del("user.name");         Boolean result = jedis.exists("user.name");         Assert.assertEquals(false, result);                   result = jedis.exists("user.pass");         Assert.assertEquals(true, result);                   jedis.close();     } }

显示通过测试
