Redis--普通工程集成redis

###新建maven工程
創建一個普通的maven工程，加入以下包，與redis相關的在最後，前面是spring相關jar包

<properties>
  	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  	<spring.version>4.2.0.RELEASE</spring.version>
  	<jackson-core.version>2.6.1</jackson-core.version>
  </properties>
  
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>

	<!-- servlet -->
	<dependency>
		<groupId>javax.servlet</groupId>
		<artifactId>javax.servlet-api</artifactId>
		<version>3.1.0</version>
	</dependency>
    
    <!-- spring -->
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-core</artifactId>
		<version>${spring.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-webmvc</artifactId>

	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-context</artifactId>
		<version>${spring.version}</version>
	</dependency>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-tx</artifactId>
		<version>${spring.version}</version>
	</dependency>
	<dependency>

	</dependency>

	<!-- redis -->

	</dependency>
	<dependency>

		<version>1.7.1.RELEASE</version>
	</dependency>

	<!-- slf4j -->
	<dependency>
		<groupId>org.slf4j</groupId>
		<artifactId>slf4j-log4j12</artifactId>

	</dependency>

###創建spring-redis.xml文件

<?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"
	xmlns:p="http://www.springframework.org/schema/p"
	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-4.2.xsd">

	<context:component-scan base-package="com.test.redis" annotation-config="true"></context:component-scan>
 	<!--  <context:property-placeholder location="classpath:redis.properties"/> -->
	<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
		<property name="maxIdle" value="10"></property>
		<property name="maxWaitMillis" value="20000"></property>
	</bean>
	<bean id="jedisConnectionFactory" 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=""></property>
		<property name="poolConfig" ref="jedisPoolConfig"></property>
	</bean>
	
	<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
		<property name="connectionFactory" ref="jedisConnectionFactory"></property>
		<!-- 序列化方式 -->
		<property name="keySerializer" >
			<bean class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
		</property>
		<property name="hashKeySerializer">
			<bean class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
		</property>
		<property name="valueSerializer">
			<bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"></bean>
		</property>
		<property name="hashValueSerializer">
			<bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"></bean>
		</property>
	</bean>
	
	<!-- 對String的操做進行封裝 -->
	<bean id="stringRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
		<property name="connectionFactory" ref="jedisConnectionFactory"></property>
	</bean>
	
</beans>

###建立源代碼
Order類

package com.test.redis;

import java.io.Serializable;
import java.util.Date;

public class Order implements Serializable {
	private static final long serialVersionUID = 1L;
	
	private String id;
	private String orderNo;
	private double price;
	private Date createDate;
	
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getOrderNo() {
		return orderNo;
	}
	public void setOrderNo(String orderNo) {
		this.orderNo = orderNo;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	public Date getCreateDate() {
		return createDate;
	}
	public void setCreateDate(Date createDate) {
		this.createDate = createDate;
	}
	@Override
	public String toString() {
		return "Order [id=" + id + ", orderNo=" + orderNo + ", price=" + price + ", createDate=" + createDate + "]";
	}
}

OrderDao類

package com.test.redis;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Repository;

@Repository
public class OrderDao {
	
	@Autowired
	private RedisTemplate<String, Order> redisTemplate;
	
	public boolean save(Order order) {
		ValueOperations<String, Order> valueOperations = redisTemplate.opsForValue();
		//valueOperations.set(order.getId(), order);
		boolean cc = valueOperations.setIfAbsent(order.getId(), order);
		return cc;
	}
	
	public Order read(String id) {
		ValueOperations<String, Order> valueOperations = redisTemplate.opsForValue();
		Order order = valueOperations.get(id);
		return order;
	}
	
	public void delete(String id) {
		ValueOperations<String, Order> valueOperations = redisTemplate.opsForValue();
		RedisOperations<String, Order> redisOperations = valueOperations.getOperations();
		redisOperations.delete(id);
	}
}

main測試方法

package com.test.redis;

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
	
	OrderDao orderDao = new OrderDao();
	
	@SuppressWarnings("resource")
	@Before
	public void setup(){
		ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-redis.xml");
		orderDao = ctx.getBean(OrderDao.class);
	}
	
	@Test
	public void saveTest(){
		Order order = new Order();
		order.setId("2");
		order.setPrice(30);
		boolean cc = orderDao.save(order);
		System.out.println(cc);
		Order order2 = orderDao.read("1");
		System.out.println(order2);
	}

}
