1.创建web项目redis\_test。

![Center][]

2.所用jar包

![Center 1][]

3.spring配置文件application.xml代码

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:context="http://www.springframework.org/schema/context"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
          	http://code.alibabatech.com/schema/dubbo        
            http://code.alibabatech.com/schema/dubbo/dubbo.xsd
    		http://www.springframework.org/schema/context 
    		http://www.springframework.org/schema/context/spring-context-4.0.xsd">
        
        
        <bean id="jedisConfig" class="redis.clients.jedis.JedisPoolConfig">
        	<property name="maxTotal" value="1024"></property>  
            <property name="maxIdle" value="200"></property>  
            <property name="maxWaitMillis" value="10000"></property>  
            <property name="testOnBorrow" value="true"></property>  
        </bean>
        
        
        <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        	<property name="hostName" value="127.0.0.1"></property>  
            <property name="port" value="6379"></property>  
            <property name="password" value="yoostar403"></property>  
            <property name="poolConfig" ref="jedisConfig"></property>  
        </bean>
        
          
        <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">  
            <property name="connectionFactory" ref="connectionFactory" />  
          
            <property name="keySerializer" ref="StringRedisSerializer" />
            <property name="valueSerializer" ref="StringRedisSerializer" />
        </bean>
        
        
        <bean id="StringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" />
        
        
        <bean id="JdkSerializationRedisSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
        
        
        <bean id="testName" class="java.lang.String">
        	<constructor-arg value="lc" />
        </bean>
    </beans>

Web.xml中加入spring配置

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/application.xml</param-value>
      </context-param>
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>

3. RedisServlet.java代码

public class RedisServlet extends HttpServlet {
    	private String name;	//测试单例多例
    	@Autowired
    	@Qualifier("redisTemplate")
    	private RedisTemplate<String, String> redisTemplate;
    	@Autowired
    	private JedisConnectionFactory connectionFactory;
    	@Autowired
    	private String testName;
    	/* 
    	 * servlet中，要想使用@autowired，必须重写init
    	 */
    	@Override
    	public void init(ServletConfig config) throws ServletException {
    		SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this,  
                    config.getServletContext());
    	}
    	
    	@Override
    	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    		if("1".equals(req.getParameter("p1"))) {
    			name = "p1";
    		}
    		Jedis jedis = connectionFactory.getShardInfo().createResource();
    		System.out.println(jedis.get("name"));
    		System.out.println("servlet name：" + name);
    		System.out.println(redisTemplate.opsForValue().multiGet(Arrays.asList("name1", "张三", "name2", "李四", "name3", "王五")));
    		System.out.println(connectionFactory);
    	}
    	
    	@Override
    	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    		super.doPost(req, resp);
    	}
    	
    	@Override
    	public void destroy() {
    		System.out.println("销毁");
    		super.destroy();
    	}
    }

5.在web.xml中配置servlet。

<servlet>
      	<servlet-name>redis</servlet-name>
      	<servlet-class>com.lc.servlet.RedisServlet</servlet-class>
      </servlet>
      <servlet-mapping>
      	<servlet-name>redis</servlet-name>
      	<url-pattern>/redis</url-pattern>
      </servlet-mapping>

现在web.xml全部如下

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
      <display-name>redis_test</display-name>
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/application.xml</param-value>
      </context-param>
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      <servlet>
      	<servlet-name>redis</servlet-name>
      	<servlet-class>com.lc.servlet.RedisServlet</servlet-class>
      </servlet>
      <servlet-mapping>
      	<servlet-name>redis</servlet-name>
      	<url-pattern>/redis</url-pattern>
      </servlet-mapping>
      
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
    </web-app>

访问： [http://localhost:8080/redis\_test/redis][http_localhost_8080_redis_test_redis]，结果如下
