1.1 首先创建一个Maven工程
File --> New --> Other，然后选择Maven目录下的Maven Project，如下图：
然后在弹出的面板中选择配置后，下一步即可，如图：
Create a simple project (skip archetype selection) ：此选项表示跳过后续的配置选项框。
Use default Workspace location：表示将项目放置到默认的工作区域下。
配置好后，Next下一步，再进行如下图的配置：
点击Finish后，便完成了Maven工程的创建。
此时在你开发工具的Workspace工作区的树桩菜单中出现了SpringRedisStudy这个项目工程.如图：
这时，工程会报错，是因为一开始创建Maven工程时，选择的是 Create a simple project 属性，所以在webapp项目下可能会没有任何文件，如图：
这个时候就需要我们自己去创建它们。
首先在 webapp 下增加一个 WEB-INF 文件夹；然后在 WEB-INF 文件夹中增加一个 web.xml(部署描述符文件);
接下来我们就要在这个文件中进行一些配置工作。

1.2 配置maven 工程文件 pom.xml
接下来我们进行详细的项目搭建，首先配置maven 工程文件 pom.xml，
因为我们要搭建Spring MVC这个工程，所以就要将相关的jar包配置到Maven工程中进行引用管理；
pom.xml文件配置如下：
1 <project xmlns="http://maven.apache.org/POM/4.0.0" 2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 4

</project>
1.3 集成spring配置文件
Maven配置好后，我们就需要在项目中进行spring配置了；
在src/main/resources目录中增加一个 config.xml包，并新建文件spring-context.xml；
这个文件的作用是配置Spring的，内容如下：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xmlns:context="http://www.springframework.org/schema/context" 7 xmlns:util="http://www.springframework.org/schema/util" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 10 http://www.springframework.org/schema/context 11 http://www.springframework.org/schema/context/spring-context-3.0.xsd 12 http://www.springframework.org/schema/mvc 13 http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 14 http://www.springframework.org/schema/util 15 http://www.springframework.org/schema/util/spring-util-3.0.xsd"> 16 17 <!-- 激活@Controller模式 --> 18 <mvc:annotation-driven /> 19 <context:annotation-config /> 20 <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 需要更改 --> 21 <context:component-scan base-package="com.test.*" /> 22 23 <!-- 引入同文件夹下的redis属性配置文件 --> 24 <import resource="redis-context.xml"/> 25 <!-- 测试用的userDao依赖注入 --> 26 <bean id="userDao" class="com.test.dao.impl.UserDao" /> 27 </beans>
在该包config.xml下同时新建redis-context.xml文件，内容如下：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation=" 7 http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 9 http://www.springframework.org/schema/context 10 http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 11 12 <!-- 引入redis.properties配置文件 --> 13 <context:property-placeholder 14 location="classpath:/config/property/redis.properties" /> 15 <!-- redis 相关配置 --> 16 <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig" 17 p:maxTotal="${redis.maxTotal}" 18 p:maxIdle="${redis.maxIdle}" 19 p:testOnBorrow="${redis.testOnBorrow}" /> 20 21 <bean id="connectionFactory" 22 class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" 23 p:hostName="${redis.host}" 24 p:port="${redis.port}" 25 p:password="${redis.password}" 26 p:database="${redis.database}" 27 p:pool-config-ref="poolConfig" /> 28 <!-- redis template definition --> 29 <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" 30 p:connectionFactory-ref="connectionFactory" 31 p:keySerializer-ref="redisTemplateKeySerializer" 32 p:valueSerializer-ref="redisTemplateValueSerializer" 33 p:hashKeySerializer-ref="redisTemplateHashKeySerializer" 34 p:hashValueSerializer-ref="redisTemplateHashValueSerializer"/> 35 <bean id="redisTemplateKeySerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" /> 36 <bean id="redisTemplateValueSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" /> 37 <bean id="redisTemplateHashKeySerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" /> 38 <bean id="redisTemplateHashValueSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" /> 39 </beans>
在src/main/resources目录中增加一个config.property包，并新建文件redis.properties，这个文件是redis的属性配置文件，内容如下：
# Redis settings # server IP redis.host=127.0.0.1 # server port redis.port=6379 redis.password=myredis redis.maxTotal=600 #redis.maxActive=600 此属性在新版本中不可用 # use dbIndex redis.database=0 # 控制一个pool最多有多少个状态为idle(空闲的)的jedis实例 redis.maxIdle=300 # 表示当borrow(引入)一个jedis实例时，最大的等待时间，如果超过等待时间(毫秒)，则直接抛出JedisConnectionException； #redis.maxWait=3000 此属性在新版本中不可用 # 在borrow一个jedis实例时，是否提前进行validate操作；如果为true，则得到的jedis实例均是可用的 redis.testOnBorrow=true
在src/main/resources目录下新建log4j.properties文件，作为log4j的属性配置文件，内容如下：
#All level less than INFO will be logged
log4j.rootLogger=info,console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.ImmediateFlush=true
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} %m%n
在项目工程未上线前暂时放在该目录，方便测试，上线后可以移动到config.property目录，此时需要在web.xml文件的<listener>节点前加入如下内容：
1 …… 2 <display-name>SpringRedisStudy</display-name> 3 <!-- 设置由Sprng载入的Log4j配置文件位置 --> 4 <context-param> 5 <param-name>log4jConfigLocation</param-name> 6 <param-value>classpath:config/property/log4j.properties</param-value> 7 </context-param> 8 <!-- Spring刷新Log4j配置文件变动的间隔,单位为毫秒 --> 9 <context-param> 10 <param-name>log4jRefreshInterval</param-name> 11 <param-value>100000</param-value> 12 </context-param> 13 <!-- 加载其他配置文件至Spring应用上下文中 --> 14 <listener> 15 ……
1.4 编写java类
在SpringRedisStudy工程的src/main/java目录下新建com.test.entity包，并新建User.java类，内容如下：
package com.test.entity;
import java.io.Serializable;
public class User implements Serializable{
private static final long serialVersionUID = 8634600086311962551L;
private String id;
private String name;
public User() {
super();
}
public User(String id, String name) {
super();
this.id = id;
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
在SpringRedisStudy工程的src/main/java目录下新建com.test.dao包并在该包下新建抽象类AbstractBaseRedisDao.java和接口IUserDao.java文件，内容如下：
package com.test.dao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
public abstract class AbstractBaseRedisDao <K, V> {
@Autowired
protected RedisTemplate<K, V> redisTemplate;
/**
* 设置redisTemplate
* @param redisTemplate 给属性redisTemplate赋值
*/
public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) {
this.redisTemplate = redisTemplate;
}
/**
* 获取 RedisSerializer
*/
protected RedisSerializer<String> getRedisSerializer() {
return redisTemplate.getStringSerializer();
}
}
package com.test.dao;
import java.util.List;
import com.test.entity.User;
public interface IUserDao {
/**
* 新增
* @param User对象
* @return 是否新增成功
*/
boolean add(User user);
/**
* 批量新增 使用pipeline方式
* @param list
* @return 是否新增成功
*/
boolean add(List<User> list);
/**
* 删除
* @param key
*/
void delete(String key);
/**
* 删除多个
* @param keys
*/
void delete(List<String> keys);
/**
* 修改
* @param user对象
* @return 是否修改成功
*/
boolean update(User user);
/**
* 通过key获取User对象
* @param keyId
* @return User对象
*/
User get(String keyId);
}
在SpringRedisStudy工程的src/main/java目录下新建com.test.dao.impl包并在该包下新建接口的实现类UserDao.java文件，内容如下：
package com.test.dao.impl;
import java.util.ArrayList;
import java.util.List;
import org.springframework.dao.DataAccessException;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisCallback;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.util.Assert;
import com.test.dao.AbstractBaseRedisDao;
import com.test.dao.IUserDao;
import com.test.entity.User;
public class UserDao extends AbstractBaseRedisDao <String, User> implements IUserDao {
/**
* 新增
* @param User对象
* @return 是否新增成功
*/
public boolean add(final User user) {
boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
RedisSerializer<String> serializer = getRedisSerializer();
byte[] key = serializer.serialize(user.getId());
byte[] name = serializer.serialize(user.getName());
return connection.setNX(key, name);
}
});
return result;
}
/**
* 批量新增 使用pipeline方式
* @param list
* @return 是否新增成功
*/
public boolean add(final List<User> list) {
Assert.notEmpty(list);
boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
public Boolean doInRedis(RedisConnection connection)
throws DataAccessException {
RedisSerializer<String> serializer = getRedisSerializer();
for (User user : list) {
byte[] key = serializer.serialize(user.getId());
byte[] name = serializer.serialize(user.getName());
connection.setNX(key, name);
}
return true;
}
}, false, true);
return result;
}
/**
* 删除
* @param key
*/
public void delete(String key) {
if (key ==null || key.length() == 0) {
return;
}
List<String> list = new ArrayList<String>();
list.add(key);
delete(list);
}
/**
* 删除多个
* @param keys
*/
public void delete(List<String> keys) {
redisTemplate.delete(keys);
}
/**
* 修改
* @param user
* @return result 是否修改成功
*/
public boolean update(final User user) {
String key = user.getId();
if (get(key) == null) {
throw new NullPointerException("数据行不存在, key = " + key);
}
boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
public Boolean doInRedis(RedisConnection connection)
throws DataAccessException {
RedisSerializer<String> serializer = getRedisSerializer();
byte[] key = serializer.serialize(user.getId());
byte[] name = serializer.serialize(user.getName());
connection.set(key, name);
return true;
}
});
return result;
}
/**
* 通过key获取User对象
* @param keyId
* @return User对象
*/
public User get(final String keyId) {
User result = redisTemplate.execute(new RedisCallback<User>() {
public User doInRedis(RedisConnection connection)
throws DataAccessException {
RedisSerializer<String> serializer = getRedisSerializer();
byte[] key = serializer.serialize(keyId);
byte[] value = connection.get(key);
if (value == null) {
return null;
}
String name = serializer.deserialize(value);
return new User(keyId, name);
}
});
return result;
}
}
在SpringRedisStudy工程的src/test/java目录的默认default包下新建测试类RedisTest.java文件，内容如下：
import java.util.ArrayList;
import java.util.List;
import junit.framework.Assert;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import com.test.dao.IUserDao;
import com.test.entity.User;
/**

@ContextConfiguration(locations = {"classpath:config/xml/spring-context.xml"})
public class RedisTest extends AbstractJUnit4SpringContextTests {
@Autowired
private IUserDao userDao;
/**

*/
@Test
public void testAddUser() {
User user = new User();
user.setId("user1");
user.setName("java2000_wl1");
boolean result = userDao.add(user);
Assert.assertTrue(result);
}
/**
* 批量新增 普通方式
*/
@Test
public void testAddUsers1() {
List<User> list = new ArrayList<User>();
for (int i = 10; i < 50000; i++) {
User user = new User();
user.setId("user" + i);
user.setName("java2000_wl" + i);
list.add(user);
}
long begin = System.currentTimeMillis();
for (User user : list) {
userDao.add(user);
}
System.out.println(System.currentTimeMillis() - begin);
}
/**
* 批量新增 pipeline方式
*/
@Test
public void testAddUsers2() {
List<User> list = new ArrayList<User>();
for (int i = 50000; i < 100000; i++) {
User user = new User();
user.setId("user" + i);
user.setName("java2000_wl" + i);
list.add(user);
}
long begin = System.currentTimeMillis();
boolean result = userDao.add(list);
System.out.println(System.currentTimeMillis() - begin);
Assert.assertTrue(result);
}
/**
* 修改
*/
@Test
public void testUpdate() {
User user = new User();
user.setId("user1");
user.setName("new_password");
boolean result = userDao.update(user);
Assert.assertTrue(result);
}
/**
* 获取
*/
@Test
public void testGetUser() {
String id = "user1";
User user = userDao.get(id);
Assert.assertNotNull(user);
Assert.assertEquals(user.getName(), "java2000_wl1");
}
/**
* 通过key删除单个
*/
@Test
public void testDelete() {
String key = "user1";
userDao.delete(key);
}
/**
* 批量删除
*/
@Test
public void testDeletes() {
List<String> list = new ArrayList<String>();
for (int i = 0; i < 100000; i++) {
list.add("user" + i);
}
userDao.delete(list);
}
/**
* 设置userDao
* @param userDao the userDao to set
*/
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
}
1.5 测试
在RedisTest.java文件上右键run as --->Run Configurations，开始测试：
测试结果：
