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
<!-- 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
<!-- 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
<?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/schema/context/spring-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
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
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
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
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
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
<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
<!-- 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
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.SpringJUnit4Cla***unner;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
/**
* 使用Jedis来测试redis
* @author hc
*
*/
@RunWith(SpringJUnit4Cla***unner.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
