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
