springboot集成redis

springboot与Redis

---

主要介绍springboot与Redis集成，内容有如下几点：

Redis安装

下载Redis的windows系统安装包，安装文件为“Redis-x64-3.2.100.msi 地址如下
—— [ Redis官网 ]

pom.xml文件加入Redis工具包

springboot与Redis的连接配置

相关配置如下所示：

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/database
spring.datasource.username=root
spring.datasource.password=12345678
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
spring.datasource.min-idle=5
spring.datasource.initial-size=5
server.port=8088
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8

代码实现

1.管理类实现

package com.xmdf.proje.rediscfg;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;

@Configuration
@EnableCaching
public class RedisConfig {
    public static RedisTemplateredisTemplate;
    public static StringRedisTemplate stringRedisTemplate;

    @Bean
    public static RedisTemplate redisTemplate(RedisConnectionFactory factory) {
        redisTemplate=new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
        return redisTemplate;
    }

    @Bean
    public static StringRedisTemplate stringRedisTemplate(RedisConnectionFactory factory) {
        stringRedisTemplate=new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(factory);
        return stringRedisTemplate;

    }

}

2.服务接口

package com.xmdf.proje.rediscfg.service;

import java.util.Map;

/**
 * 
 * @author Houyer
 * @date 2018-04-24
 *  @category 获取、存入redis缓存值
 */
public interface RedisService {
    public void putRedisKeyObjectData(MapredisKVMap);
    public Object getRedisKeyObjectData(MapredisVKMap);
    public void putRedisKeyStringData(MapredisKVMap);
    public String getRedisKeyStringData(MapredisVKMap);
}

3.服务接口实现类

package com.xmdf.proje.rediscfg.serviceimpl;
import java.util.Map;
import org.springframework.stereotype.Service;
import com.xmdf.proje.rediscfg.RedisConfig;
import com.xmdf.proje.rediscfg.service.RedisService;

@Service
public class RedisServiceImpl implements RedisService{
    @Override
    public void putRedisKeyObjectData(Map redisKVMap) {
        String redisKey=(String) redisKVMap.get("key");
        Object objectData=redisKVMap.get("data");
        if (!RedisConfig.redisTemplate.hasKey(redisKey)) {
            RedisConfig.redisTemplate.opsForValue().set(redisKey, objectData);
        }
    }
    @Override
    public Object getRedisKeyObjectData(Map redisVKMap) {
        String redisKey=redisVKMap.get("key");
        Object objData=null;
        if (RedisConfig.redisTemplate.hasKey(redisKey)) {
            objData=RedisConfig.redisTemplate.opsForValue().get(redisKey);
        }
        return objData;
    }
    @Override
    public void putRedisKeyStringData(Map redisKVMap) {
        String redisKey=(String) redisKVMap.get("key");
        String stringData=redisKVMap.get("data");
        if (!RedisConfig.stringRedisTemplate.hasKey(redisKey)) {
            RedisConfig.stringRedisTemplate.opsForValue().set(redisKey, stringData);
        }   
    }
    @Override
    public String getRedisKeyStringData(Map redisVKMap) {
        String redisKey=(String) redisVKMap.get("key");
        String stringData="";
        if (RedisConfig.stringRedisTemplate.hasKey(redisKey)) {
            stringData=RedisConfig.stringRedisTemplate.opsForValue().get(redisKey);
        }
        return stringData;
    }
}

4.控制层

package com.xmdf.proje.controller;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.UUID;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.xmdf.proje.cfgbean.User;
import com.xmdf.proje.rediscfg.service.RedisService;

@RestController
public class HelloWordController {
      @Autowired
       private JdbcTemplate jdbcTemplate;
      @Autowired
       private StringRedisTemplate stringRedisTemplate;  
      @Autowired
      RedisService redisService;
    @RequestMapping("/index")
    public String index(){
        String redisSTR="";
        ValueOperationsvopt=this.stringRedisTemplate.opsForValue();
        String key="redis_key";
        if (this.stringRedisTemplate.hasKey(key)) {
            redisSTR=vopt.get(key);
        }
        return redisSTR;
    }
    @RequestMapping("/getUser")
    public List getUsers(){
        ListreturnList=new ArrayList();
        ValueOperationsvopt=this.stringRedisTemplate.opsForValue();
        User user=new User();
        String key="redis_key";
        if (this.stringRedisTemplate.hasKey(key)) {
            vopt.set(key,UUID.randomUUID().toString() );
        }
        for (int i = 0; i < 2; i++) {
            user=new User();
            user.setUserId(UUID.randomUUID().toString());
            user.setUserName(UUID.randomUUID().toString());
            user.setUserNo(UUID.randomUUID().toString());
            user.setUserSex(UUID.randomUUID().toString());
            returnList.add(user);
        }
        return returnList;
    }   
    @RequestMapping("/index_put_user")
    public boolean putTestRedis(){
        User user=new User();
        user.setUserId(UUID.randomUUID().toString());
        user.setUserName("Hello Word");
        user.setUserNo("123456");
        user.setUserSex("男");
        MapredisKVMap=new HashMap<>();
        redisKVMap.put("key", "user");
        redisKVMap.put("data", user);
        redisService.putRedisKeyObjectData(redisKVMap);
        return true;
    }
    @RequestMapping("/index_get_user")
    public User getTestUser() {
        MapredisMap=new HashMap<>();
        redisMap.put("key", "user");
        User user=(User) redisService.getRedisKeyObjectData(redisMap);
        return user;
    }
}

5.User类

package com.xmdf.proje.cfgbean;
import java.io.Serializable;
@SuppressWarnings("serial")
public class User  implements Serializable{
    private String userId;
    private String userName;
    private String userNo;
    private String userSex;
    public User(String userId, String userName, String userNo, String userSex) {
        super();
        this.userId = userId;
        this.userName = userName;
        this.userNo = userNo;
        this.userSex = userSex;
    }
    public User() {
        // TODO Auto-generated constructor stub
    }
    public String getUserId() {
        return userId;
    }
    public void setUserId(String userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getUserNo() {
        return userNo;
    }
    public void setUserNo(String userNo) {
        this.userNo = userNo;
    }
    public String getUserSex() {
        return userSex;
    }
    public void setUserSex(String userSex) {
        this.userSex = userSex;
    }
    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((userId == null) ? 0 : userId.hashCode());
        result = prime * result + ((userName == null) ? 0 : userName.hashCode());
        result = prime * result + ((userNo == null) ? 0 : userNo.hashCode());
        result = prime * result + ((userSex == null) ? 0 : userSex.hashCode());
        return result;
    }
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        User other = (User) obj;
        if (userId == null) {
            if (other.userId != null)
                return false;
        } else if (!userId.equals(other.userId))
            return false;
        if (userName == null) {
            if (other.userName != null)
                return false;
        } else if (!userName.equals(other.userName))
            return false;

    }
    /* (non-Javadoc)
