Spring+SpringMVC+Redis

1. 搭建Redis环境
   Redis github下载地址
   CSDN资源下载地址
   目前官方推荐的最新稳定版本为3.2.1
   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
   
   看到如下截图，Redis即启动成功
2. 搭建spring环境
   添加springmvc需要的依赖包

        <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需要的依赖包

        <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>

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>

redis.properties

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

4. 配置DispatcherServlet
这里采用硬编码的方式对DispatcherServlet进行配置，不依赖于web.xml

package white.yu;import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;import white.yu.config.RootConfig;import white.yu.config.WebConfig;/** * DispatchServlet 拦截器  * @author white * */public class MainDispatcherServletInitializer 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 };    }    /**     * 配置DispatcherServlet映射路径     */    @Override    protected String[] getServletMappings() {        return new String[] { "/" };    }}

应用上下文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;    }    /**     * 配置静态资源处理器     */    @Override    public void configureDefaultServletHandling(            DefaultServletHandlerConfigurer configurer) {        super.configureDefaultServletHandling(configurer);        configurer.enable();    }}

1. 编写测试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() {        // 获取Redis数据库中的所有user数据        // -1 表示获取数据库中的所有数据        List<User> range = listOps.range("user", 0, -1);        return range;    }    @RequestMapping("/add")    @ResponseBody    public User list(User user){        // 添加到Redis数据库        listOps.leftPush("user", user);        return user;    }}
