这篇文章主要介绍 Redis 框架如何搭建 SpringBoot2.X，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
一、使用 Spring Initializr 创建项目 web 项目
1、File→New→Project
2、点击 Next 如图所示，命名好 Group 和 Artifact
3、Next 后如图所示，勾选中需要的依赖，Spring Initializr 会自动导入所需的 starter
4、创建项目成功后，pom.xml 文件中的依赖如下
?xml version= 1.0 encoding= UTF-8 ?
project xmlns= http://maven.apache.org/POM/4.0.0 xmlns:xsi= http://www.w3.org/2001/XMLSchema-instance
xsi:schemaLocation= http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd

5、在 pom.xml 文件中添加 redis 的 starter
dependency
groupId org.springframework.boot /groupId
artifactId spring-boot-starter-data-redis /artifactId
/dependency6、创建 JavaBean 用于封装数据库数据，需要实现 Serializable
package com.henya.springboot.bean;
import java.io.Serializable;
public class Employee implements Serializable{
private Integer id;
private String lastName;
private String email;
private Integer gender; // 性别 1 男 0 女
private Integer dId;
public Employee(Integer id, String lastName, String email, Integer gender, Integer dId) {super();
this.id = id;
this.lastName = lastName;
this.email = email;
this.gender = gender;
this.dId = dId;
public Integer getId() {
return id;
public void setId(Integer id) {
this.id = id;
public String getLastName() {
return lastName;
public void setLastName(String lastName) {
this.lastName = lastName;
public String getEmail() {
return email;
public void setEmail(String email) {
this.email = email;
public Integer getGender() {
return gender;
public void setGender(Integer gender) {
this.gender = gender;
public Integer getdId() {
return dId;
public void setdId(Integer dId) {
this.dId = dId;
@Override
public String toString() {
return Employee [id= + id + , lastName= + lastName + , email= + email + , gender= + gender + , dId=
+ dId + ]
} 注意：
在写 JavaBean 对象时需要实现 Serializable 接口否则会报以下错误：
Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException
7、整合 Mybatis 操作数据库，在 application.properties 配置文件中配置数据源信息
#serverTimezone 用于指定时区，不然会报错
spring.datasource.url=jdbc:mysql://localhost:3306/cache?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
# 开启驼峰命名法规则
mybatis.configuration.map-underscore-to-camel-case=true
#日志级别
logging.level.com.henya.springboot.mapper=debug8、使用注解版 Mybatis 创建 Mapper
package com.henya.springboot.mapper;
@Select(SELECT * FROM employee WHERE id=#{id} )
public Employee getEmpById(Integer id);
@Update(UPDATE employee SET lastName=#{lastName},email=#{email},gender=#{gender},d_id=#{dId} WHERE id=#{id} )
public void updateEmp(Employee employee);
@Delete(DELETE FROM emlpoyee WHERE id=#{id} )
public void delEmpById(Integer id);
@Insert(INSERT INTO employee(lastName, email, gender, d_id) VALUES (#{lastName}, #{email}, #{gender}, #{dId}) )
public Employee insertEmp(Employee employee);
@Select(SELECT * FROM employee WHERE lastName=#{lastName} )
public Employee getEmpByLastName(String lastName);
} 注意：
需要使用使用 @MapperScan 注解扫描 Mapper 所在的接口，只需要加在主程序类上即可。除此之外，还要使用 @EnableCaching 用于开启缓存。
@MapperScan(com.henya.springboot.mapper)
@SpringBootApplication
@EnableCaching // 开启缓存
public class SpringBootRedisApplication {public static void main(String[] args) {SpringApplication.run(SpringBootRedisApplication.class, args);
}9、编写 Service 类，用于访问数据库或 redis 缓存
package com.henya.springboot.service;
import com.henya.springboot.bean.Employee;
import com.henya.springboot.mapper.EmployeeMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.*;
import org.springframework.stereotype.Service;
@CacheConfig(cacheNames = emp) // 抽取缓存的公共配置
@Service
public class EmployeeService {
@Autowired
EmployeeMapper employeeMapper;
* @param id
* @return
@Cacheable(cacheNames = { emp},keyGenerator = myKeyGenerator )
public Employee getEmpById(Integer id) {
System.err.println( 开始查询 + id + 号员工
Employee employee = employeeMapper.getEmpById(id);
return employee;
* @CachePut：既调用方法（这个方法必须要执行），又更新缓存数据
* @param employee
* @return
@CachePut(value = emp ,key = #result.id)
public Employee updateEmp(Employee employee){System.err.println( 开始更新 + employee.getId() + 号员工
employeeMapper.updateEmp(employee);
return employee;
* @CacheEvict：缓存清除
* @param id
@CacheEvict(value = emp ,beforeInvocation = true)
public void deleteEmp(Integer id){
System.err.println( 删除 + id + 员工
int i = 10/0;
}10、编写 Controller 类
package com.henya.springboot.controller;
import com.henya.springboot.bean.Employee;
import com.henya.springboot.service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
* @Description:
* @Author：HenYa
* @CreatTime：2019/12/1 12:44
@RestController
public class EmployeeController {
@Autowired
EmployeeService employeeService;
@GetMapping(/emp/{id} )
public Employee getEmpById(@PathVariable( id) Integer id){Employee employee = employeeService.getEmpById(id);
return employee;
@GetMapping(/emp)
public Employee updateEmp(Employee employee){Employee emp = employeeService.updateEmp(employee);
return emp;
}二、测试 SpringBoot 整合 Redis 是否成功
1、在浏览器访问，也可以使用测试类，笔者使用了浏览器访问 http://localhost:8080/emp/ 1 进行测试，初次访问时，控制台会提示开始查询 1 号员工，如图所示。
2、再次访问时，控制台并没有 sql 日志，如图所示。
3、此时使用 RedisDesktopManager 工具查看 redis 时有数据，并且 cacheName 为 emp，如图所示
只是 emp 对象被序列化了。查看源码可知 Redis 默认使用 Jdk 进行序列化。
static RedisSerializer Object java(@Nullable ClassLoader classLoader) {return new JdkSerializationRedisSerializer(classLoader);
}
查看 RedisSerializer 接口的实现有以下几种：
我们常用的就是以 json 的格式进行序列化。但是需要自定义 RedisCacheManager。
三、自定义 RedisCacheManager
package com.henya.springboot.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.cache.RedisCacheWriter;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import org.springframework.data.redis.serializer.RedisSerializer;
* @Description:
* @Author：HenYa
* @CreatTime：2019/12/6 20:50
@Configuration
public class MyRedisConfig {
@Bean
public RedisCacheManager empCacheManager(RedisConnectionFactory redisConnectionFactory){//RedisCacheManager redisCacheManager = new RedisCacheManager(redisConnectionFactory);
RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory);
RedisSerializer Object redisSerializer = new GenericJackson2JsonRedisSerializer();
RedisSerializationContext.SerializationPair Object pair = RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer);
RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig().serializeValuesWith(pair);
// 默认会将 CacheName 作为 key 的前缀
return new RedisCacheManager(redisCacheWriter, redisCacheConfiguration);
}
