话不多说，直接开始，这里就不介绍怎么创建Springboot项目了，百度一下，多的是，先来一张项目的结构图：
安装Redis
网上很多安装教程，这里就不再赘述了，我安装的是Redis 3.2.100 windows版本
pom.xml

application.yml
这里我使用的是yml格式，个人比较喜欢而已。
spring: datasource: type: com.alibaba.druid.pool.DruidDataSource driverClassName: com.mysql.jdbc.Driver driver-class-name: com.mysql.jdbc.Driver platform: mysql url: jdbc:mysql://127.0.0.1:3306/joe?useUnicode=true&characterEncoding=utf-8&useSSL=false username: root password: 123456 initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT1FROMDUAL testWhileIdle: true testOnBorrow: false testOnReturn: false filters: stat,wall,log4j logSlowSql: true mybatis: mapper-locations: classpath:com/example/mapper/*Mapper.xml
mybatis-config
只是在里面取了一些别名而已，没有其他的什么配置。
<?xml version="1.0" encoding="utf-8" ?> <configuration> <typeAliases> <typeAlias alias="Integer" type="java.lang.Integer"/> <typeAlias alias="Long" type="java.lang.Long"/> <typeAlias alias="HashMap" type="java.util.HashMap"/> <typeAlias alias="LinkedHashMap" type="java.util.LinkedHashMap"/> <typeAlias alias="ArrayList" type="java.util.ArrayList"/> <typeAlias alias="LinkedList" type="java.util.LinkedList"/> </typeAliases> </configuration>
DruidConfiguration
这是阿里的一个数据库连接池，想详细了解的可以百度。
import com.alibaba.druid.pool.DruidDataSource; import com.alibaba.druid.support.http.StatViewServlet; import com.alibaba.druid.support.http.WebStatFilter; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.web.servlet.FilterRegistrationBean; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import javax.sql.DataSource; @Configuration public class DruidConfiguration { private static Logger logger = LoggerFactory.getLogger(DruidConfiguration.class); @Bean public ServletRegistrationBean druidServlet() { ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); servletRegistrationBean.addInitParameter("allow", "127.0.0.1"); servletRegistrationBean.addInitParameter("deny", "192.168.1.100"); servletRegistrationBean.addInitParameter("loginUsername", "admin"); servletRegistrationBean.addInitParameter("loginPassword", "admin"); servletRegistrationBean.addInitParameter("resetEnable", "false"); return servletRegistrationBean; } @Bean public FilterRegistrationBean filterRegistrationBean() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); filterRegistrationBean.addUrlPatterns("/*"); filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*"); return filterRegistrationBean; } @Bean @ConfigurationProperties(prefix = "spring.datasource") public DataSource druidDataSource() { DruidDataSource druidDataSource = new DruidDataSource(); return druidDataSource; } }
UserMapper.xml
<?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.example.mapper.UserDao"> <resultMap id="BaseResultMap" type="com.example.entity.User"> <id column="email" property="email"/> <result column="password" property="password"/> <result column="username" property="username"/> <result column="regTime" property="regTime"/> </resultMap> <select id="selectAllUser" resultMap="BaseResultMap"> select regTime, password, username, email from user </select> </mapper>

import javax.annotation.Resource; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.core.ValueOperations; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.data.redis.serializer.StringRedisSerializer; import org.springframework.stereotype.Service; @Service public class RedisService { @Resource private RedisTemplate<String,Object> redisTemplate; public void set(String key, Object value) { //更改在redis里面查看key编码问题 RedisSerializer redisSerializer =new StringRedisSerializer(); redisTemplate.setKeySerializer(redisSerializer); ValueOperations<String,Object> vo = redisTemplate.opsForValue(); vo.set(key, value); } public Object get(String key) { ValueOperations<String,Object> vo = redisTemplate.opsForValue(); return vo.get(key); } }

到这里，基本的项目就已经搭建完毕了
先启动Redis，然后启动项目就可以运行了
