Spring+SpringMVC+Redis

Spring+SpringMVC+Redis

1. 搭建Redis環境
   Redis github下載地址 CSDN資源下載地址
   目前官方推薦的最新穩定版本為3.2.1
   下載之後直接解壓得到以下目錄結構

點擊redis-server.exe即可啟動Redis資料庫

看到如下截圖，Redis即啟動成功

1. 搭建spring環境
   添加springmvc需要的依賴包

<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>

1. 集成Redis
   ①添加Redis需要的依賴包

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

②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-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.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單節點資料庫連接配置 --> <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是對Jedis的對redis操作的擴展，有更多的操作，封裝使操作更便捷 --> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="jedisConnectionFactory" /> </bean></beans>

redis.properties

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

1. 配置DispatcherServlet
   這裡採用硬編碼的方式對DispatcherServlet進行配置，不依賴於web.xml

package white.yu;import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;import white.yu.config.RootConfig;import white.yu.config.WebConfig;/** * DispatchServlet 攔截器 * @author white * */public class MainDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { /** * 配置應用上下文 */ @Override protected Class<?>[] getRootConfigClasses() { return new Class<?>[] { RootConfig.class }; } /** * 配置web上下文 */ @Override protected Class<?>[] getServletConfigClasses() { return new Class<?>[] { WebConfig.class }; } /** * 配置DispatcherServlet映射路徑 */ @Override protected String[] getServletMappings() { return new String[] { "/" }; }}

應用上下文RootConfig

package white.yu.config;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.ComponentScan.Filter;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.FilterType;import org.springframework.context.annotation.ImportResource;import org.springframework.stereotype.Controller;import org.springframework.web.servlet.config.annotation.EnableWebMvc;@Configuration@ComponentScan(basePackages = { "white.yu" }, excludeFilters = { @Filter(type = FilterType.ANNOTATION, value = Controller.class), @Filter(type = FilterType.ANNOTATION, value = EnableWebMvc.class) })@ImportResource("classpath:spring/spring-*.xml") //引入redis的配置文件public class RootConfig {}

web上下文 WebConfig

package white.yu.config;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({ "white.yu.web" })public class WebConfig extends WebMvcConfigurerAdapter { /** * 配置視圖解析器 * * @return */ @Bean public ViewResolver viewResolver() { InternalResourceViewResolver resolver = new InternalResourceViewResolver(); resolver.setPrefix("/WEB-INF/views/"); resolver.setSuffix(".html"); resolver.setExposePathVariables(true); return resolver; } /** * 配置靜態資源處理器 */ @Override public void configureDefaultServletHandling( DefaultServletHandlerConfigurer configurer) { super.configureDefaultServletHandling(configurer); configurer.enable(); }}

1. 編寫測試Controller

package white.yu.web;import java.util.List;import javax.annotation.Resource;import org.springframework.beans.factory.annotation.Autowired;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;import white.yu.cache.RedisCache;import white.yu.entity.User;@Controller@RequestMapping("user")public class UserController { @Resource(name = "redisTemplate") private ListOperations<String, User> listOps; @RequestMapping("/list") @ResponseBody public List<User> list() { // 獲取Redis資料庫中的所有user數據 // -1 表示獲取資料庫中的所有數據 List<User> range = listOps.range("user", 0, -1); return range; } @RequestMapping("/add") @ResponseBody public User list(User user){ // 添加到Redis資料庫 listOps.leftPush("user", user); return user; }}
