Spring基于注解整合Redis完整实例

在《Redis之——Spring整合Redis》一文中，向大家介绍了如何将spring与Redis整合起来，但不是基于注解的形式，很多同学都希望能够通过注解的形式来简单的将Spring与Redis整合起来，这样，在使用的时候，只需要在相应的方法上加上注解，便可以使方法轻松的调用Redis的缓存。那么今天就来向大家介绍如何用基于注解的形式来整合Spring与Redis。

一、项目搭建

今天，我们不使用hibernate来操作数据库了，我们今天选择的框架是： Spring4(包括mvc、context、orm) + MyBatis3，所以，我们今天的基础架构是：Spring4(包括mvc、context、orm) + MyBatis3+Redis

1、构建pom.xml

        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

2、创建测试数据库：lyz，测试数据表：user

DROP DATABASE IF EXISTS `lyz`;
CREATE DATABASE `lyz`;
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) DEFAULT NULL,
 `sex` varchar(255) DEFAULT NULL,
 `age` int(11) DEFAULT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3、创建实体类user

package com.lyz.user.bean; 

import java.io.Serializable; 

import org.codehaus.jackson.map.annotate.JsonSerialize; 

import com.fasterxml.jackson.databind.PropertyNamingStrategy;
import com.fasterxml.jackson.databind.annotation.JsonNaming; 

/**
 * 用户实体类
 * @author liuyazhuang
 *
 */
@JsonSerialize
@JsonNaming(PropertyNamingStrategy.LowerCaseWithUnderscoresStrategy.class)
public class User implements Serializable{
  private static final long serialVersionUID = 1332643889208978231L; 

  /**
   * id
   */
  private Integer id; 

  /**
   * 姓名
   */
  private String name; 

  /**
   * 性别
   */
  private String sex; 

  /**
   * 年龄
   */
  private Integer age; 

  public User() {
    super();
  } 

  public User(Integer id, String name) {
    super();
    this.id = id;
    this.name = name;
  } 

  public User(String name, String sex, Integer age) {
    super();
    this.name = name;
    this.sex = sex;
    this.age = age;
  } 

  public Integer getId() {
    return id;
  } 

  public void setId(Integer id) {
    this.id = id;
  } 

  public String getName() {
    return name;
  } 

  public void setName(String name) {
    this.name = name;
  } 

  public String getSex() {
    return sex;
  } 

  public void setSex(String sex) {
    this.sex = sex;
  } 

  public Integer getAge() {
    return age;
  } 

  public void setAge(Integer age) {
    this.age = age;
  } 

  @Override
  public String toString() {
    return "User [id=" + id + ", name=" + name + ", sex=" + sex + ", age=" + age + "]";
  } 

}

4、创建UserMapper接口

此接口定义了与MyBatis交互的接口协议，通过此接口与MyBatis框架通信，由MyBatis框架实现对数据库的增删改查操作。

package com.lyz.user.mapper; 

import java.util.List; 

import com.lyz.user.bean.User; 

/**
 * UserMapper接口
 * @author liuyazhuang
 *
 */
public interface UserMapper { 

  /**
   * 保存用户
   * @param user
   */
  void saveUser(User user); 

  /**
   * 获取所有用户列表
   * @return
   */
  List<User> getAllUser(); 

  /**
   * 根据id查询用户信息
   * @param id
   * @return
   */
  User getUserById(Integer id); 

  /**
   * 更新用户的名称
   * @param user
   */
  void renameUser(User user); 

  /**
   * 根据id删除指定的用户
   * @param id
   */
  void deleteUserById(Integer id);
}

5、创建UserMapper.xml

此文件中主要实现了UserMapper接口定义的方法，即实现对数据库的增删改查操作。

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.lyz.user.mapper.UserMapper" > 

  <!-- 插入一条城市记录 -->
  <insert id="saveUser" parameterType="com.lyz.user.bean.User">
    insert into user (name, sex, age)
    values ( #{name}, #{sex}, #{age} )
  </insert> 

  <!-- 根据省份名称返回该省份下的所有城市列表 -->
  <select id="getAllUser" resultType="com.lyz.user.bean.User">
    select u.id, u.name, u.sex, u.age from user u
  </select> 

  <!-- 根据 city_code 查找城市信息 -->
  <select id="getUserById" resultType="com.lyz.user.bean.User" parameterType="java.lang.Integer">
    select u.id, u.name, u.sex, u.age from user u where u.id = #{id}
  </select> 

  <!-- 重命名城市 -->
  <update id="renameUser" parameterType="com.lyz.user.bean.User">
    update user set name = #{name} where id = #{id}
  </update>  

  <!-- 删除一个城市记录 -->
  <delete id="deleteUserById" parameterType="java.lang.Integer">
    delete from user where id = #{id}
  </delete>
</mapper>

6、创建UserDao接口

package com.lyz.user.dao; 

import java.util.List; 

import com.lyz.user.bean.User; 

/**
 * 用户dao接口
 * @author liuyazhuang
 *
 */
public interface UserDao {
   /**
   * 保存用户
   * @param user
   */
  void saveUser(User user); 

  /**
   * 获取所有用户列表
   * @return
   */
  List<User> getAllUser(); 

  /**
   * 根据id查询用户信息
   * @param id
   * @return
   */
  User getById(Integer id); 

  /**
   * 更新用户的名称
   * @param user
   */
  void rename(User user); 

  /**
   * 根据id删除指定的用户
   * @param id
   */
  void deleteById(Integer id);
}

7、创建UserDao的实现类UserDaoImpl

此类主要实现UserDao中定义的接口，主要实现方法是注入UserMapper接口的实例对象，调用UserMapper接口实例的方法来实现相应的操作。

package com.lyz.user.dao.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Repository;
import com.lyz.user.bean.User;
import com.lyz.user.dao.UserDao;
import com.lyz.user.mapper.UserMapper;
/**
 * Dao实现类
 * @author liuyazhuang
 *
 */
@Repository
public class UserDaoImpl implements UserDao {
  @Resource
  private UserMapper mUserMapper; 

  @Override
  public void saveUser(User user) {
    mUserMapper.saveUser(user);
  } 

  @Override
  public List<User> getAllUser() {
    return mUserMapper.getAllUser();
  } 

  @Override
  public User getById(Integer id) {
    return mUserMapper.getUserById(id);
  } 

  @Override
  public void rename(User user) {
    mUserMapper.renameUser(user);
  } 

  @Override
  public void deleteById(Integer id) {
    mUserMapper.deleteUserById(id);
  } 

}

8、创建UserService接口

package com.lyz.user.service;
import java.util.List;
import com.lyz.user.bean.User;
/**
 * 用户service接口
 * @author liuyazhuang
 *
 */
public interface UserService {
   /**
   * 保存用户
   * @param user
   */
  void saveUser(String name, String sex, Integer age); 

  /**
   * 获取所有用户列表
   * @return
   */
  List<User> getAllUser(); 

  /**
   * 根据id查询用户信息
   * @param id
   * @return
   */
  User getUserById(Integer id); 

  /**
   * 更新用户的名称
   * @param user
   */
  void renameUser(String name, Integer id); 

  /**
   * 根据id删除指定的用户
   * @param id
   */
  void deleteUserById(Integer id);
}

9、创建UserService接口实现类UserServiceImpl

package com.lyz.user.service.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import com.lyz.user.bean.User;
import com.lyz.user.dao.UserDao;
import com.lyz.user.service.UserService;
/**
 * UserService实现类
 * @author liuyazhuang
 *
 */
@Service
@Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
public class UserServiceImpl implements UserService {
  @Resource
  private UserDao mUserDao; 

  @Override
  @CacheEvict(value = { "saveUser"}, allEntries = true)
  public void saveUser(String name, String sex, Integer age) {
    User user = new User(name, sex, age);
    mUserDao.saveUser(user);
  } 

  @Override
  @Cacheable("getAllUser")
  public List<User> getAllUser() {
    return mUserDao.getAllUser();
  } 

  @Override
  @Cacheable("getUserById")
  public User getUserById(Integer id) {
    return mUserDao.getById(id);
  } 

  @Override
  @CacheEvict(value = { "getAllUser", "getUserById" }, allEntries = true)
  public void renameUser(String name, Integer id) {
    mUserDao.rename(new User(id, name));
  } 

  @Override
  @CacheEvict(value = { "getAllUser", "getUserById" }, allEntries = true)
  public void deleteUserById(Integer id) {
    mUserDao.deleteById(id);
  } 

}

10、创建UserController

package com.lyz.user.controller;
import java.util.List;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.lyz.user.bean.User;
import com.lyz.user.service.UserService;
/**
 * UserController类
 * @author liuyazhuang
 *
 */
@Controller
@RequestMapping("/user")
public class UserController {
  private final Log logger = LogFactory.getLog(this.getClass());
  @Autowired
  private UserService mUserService; 

  /**
   * 保存用户
   * @param name
   * @param sex
   * @param age
   * @return
   */
  @RequestMapping("/save")
  @ResponseBody
  public Integer save(@RequestParam(value="name", defaultValue="") String name,
      @RequestParam(value="sex", defaultValue="") String sex,
      @RequestParam(value="age", defaultValue="0") String age){
    logger.debug(name);
    mUserService.saveUser(name, sex, Integer.parseInt(age));
    return 1;
  } 

  /**
   * 获取所有用户列表
   * @return
   */
  @RequestMapping("/getall")
  @ResponseBody
  public Object getAllUser(){
    List<User> users = mUserService.getAllUser();
    for(User u : users){
      logger.debug(u.toString());
    }
    return users;
  }
  /**
   * 根据用户id获取用户信息
   * @return
   */
  @RequestMapping("/getUserById")
  @ResponseBody
  public Object getUserById(@RequestParam(value="id", defaultValue="0") String id){
    User user = mUserService.getUserById(Integer.parseInt(id));
    logger.debug(user.toString());
    return user;
  } 

  /**
   * 根据用户id获取用户信息
   * @return
   */
  @RequestMapping("/renameUser")
  @ResponseBody
  public Integer renameUser(@RequestParam(value="id", defaultValue="0") String id,
               @RequestParam(value="name", defaultValue="") String name){
    logger.debug(id + "=========" + name);
    mUserService.renameUser(name, Integer.parseInt(id));
    return 1;
  }
  /**
   * 根据用户id获取用户信息
   * @return
   */
  @RequestMapping("/delete")
  @ResponseBody
  public Integer delete(@RequestParam(value="id", defaultValue="0") String id){
    logger.debug(id);
    mUserService.deleteUserById(Integer.parseInt(id));
    return 1;
  }
}

到此，只要再创建相应的配置文件，我们就可以实现Spring+MyBatis框架的整合了，下面我们创建一个整合Redis的关键类RedisCacheConfig，这个类继承CachingConfigurerSupport。

11、创建RedisCacheConfig类

package com.lyz.cache.redis;
import java.lang.reflect.Method;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate; 

/**
 * 以Spring与配置文件来管理的redis缓存配置类
 * @author liuyazhuang
 *
 */
@Configuration
@EnableCaching
public class RedisCacheConfig extends CachingConfigurerSupport { 

  private volatile JedisConnectionFactory mJedisConnectionFactory;
  private volatile RedisTemplate<String, String> mRedisTemplate;
  private volatile RedisCacheManager mRedisCacheManager; 

  public RedisCacheConfig() {
    super();
  } 

  public RedisCacheConfig(JedisConnectionFactory mJedisConnectionFactory, RedisTemplate<String,String> mRedisTemplate,
      RedisCacheManager mRedisCacheManager) {
    super();
    this.mJedisConnectionFactory = mJedisConnectionFactory;
    this.mRedisTemplate = mRedisTemplate;
    this.mRedisCacheManager = mRedisCacheManager;
  } 

  public JedisConnectionFactory redisConnectionFactory() {
    return mJedisConnectionFactory;
  } 

  public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {
    return mRedisTemplate;
  } 

  public CacheManager cacheManager(RedisTemplate<?, ?> redisTemplate) {
    return mRedisCacheManager;
  } 

  @Bean
  public KeyGenerator customKeyGenerator() {
    return new KeyGenerator() {
      @Override
      public Object generate(Object o, Method method, Object... objects) {
        StringBuilder sb = new StringBuilder();
        sb.append(o.getClass().getName());
        sb.append(method.getName());
        for (Object obj : objects) {
          sb.append(obj.toString());
        }
        return sb.toString();
      }
    };
  }
}

这个类中的所有属性、字段都是在Spring的配置文件lyz-applicationContext.xml文件中注入的，稍后我们介绍如何注入这些属性字段。

下面介绍每个配置文件的内容，注：所有的配置文件(除了web.xml)，都是放在classpath路径下的。

12、创建数据库的配置文件jdbc.properties

jdbc.host=127.0.0.1
jdbc.database=lyz
jdbc.port=3306
jdbc.username=root
jdbc.password=root

13、创建log4j日志配置文件log4j.properties

# Global logging configuration
log4j.rootLogger=WARN,stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c:%L - %m%n
# mybatis log
log4j.logger.com.lyz.user.mapper.UserMapper=DEBUG
# lyz log
log4j.logger.com.lyz.user.controller=DEBUG
log4j.logger.com.lyz.user.service=DEBUG 

14、创建redis配置文件redis.properties

# Redis settings
redis.host=192.168.157.130
redis.port=6379
redis.pass=liuyazhuang
redis.dbIndex=0
redis.expiration=3000
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true 

15、创建SpringMVC的配置文件lyzmvc-servlet.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:p="http://www.springframework.org/schema/p"
  xmlns:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="http://www.springframework.org/schema/beans 

http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 

  <!-- class annotation related... start -->
  <context:component-scan base-package="com.lyz.*.controller" />
  <!-- class annotation related... end --> 

  <!-- jsp page related... start -->
  <bean id="viewResolver"
    class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass"
      value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
  </bean>
  <!-- jsp page related... end --> 

  <!-- rest json related... start -->
  <bean id="mappingJacksonHttpMessageConverter"
     class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <property name="supportedMediaTypes">
      <list>
        <value>application/json;charset=UTF-8</value>
      </list>
    </property>
  </bean>
  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
      <list>
        <ref bean="mappingJacksonHttpMessageConverter"/>
      </list>
    </property>
  </bean>
  <!-- rest json related... end -->
</beans>

16、创建MyBatis配置文件mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
  <settings>
    <setting name="mapUnderscoreToCamelCase" value="true"/>
  </settings>
</configuration>

17、创建Spring核心配置文件lyz-applicationContext.xml

<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"

注：在lyz-applicationContext.xml配置文件中，配置了Spring的注解、注入了RedisCacheConfig中的属性字段。

18、完善web.xml文件

二、运行测试

这里我们使用Apache JMeter来测试我们的程序，大家可以到http://jmeter.apache.org/download_jmeter.cgi下载Apache JMeter。

1、启动程序，使用JMeter调用保存用户接口

首先按照图示配置JMeter,其中访问路径和端口按照实际需要配置：

点击启动按钮，也就是上方的

图标：

点击“查看结果树”并打开“响应数据”选项：

我们看到返回的结果是1，证明我们成功的调用了保存用户的接口。

下面我们来看看数据库表：

已经将数据保存到数据库了。

2、调用查询用户的接口

首先按照图示配置JMeter,其中访问路径和端口按照实际需要配置：

这些我们先看看redis服务器中是否存在相应的数据：

此时,redis服务器中并没有任何数据，下面我们点击启动，执行程序：

点击“查看结果数”并打开“响应数据”，如下：

返回了相应的数据。

我们再打开控制台看看输出的语句：

说明首次获取数据是从数据库中获取的。下面我们再看看redis缓存中是否存在数据了：

说明首次获取数据，从数据库中取出的数据已经放在了redis缓存服务器中。

我们再次点击Jmeter的启动按钮，执行查询用户的操作：

查看Jmeter的“查看结果数”中的“响应数据”选项：

返回了正确的结果，同时，我们再看看Eclipse的控制台：

已经没有再从数据库中获取数据了，说明再次执行查询用户的操作，程序是直接从Redis缓存中获取的数据。

至此，Spring基于注解整合Redis介绍完毕。

三、源码下载
