一 安装Redis
1 Docker下安装。
安装完成后,执行下面命令:
docker run -d -p 6379:6379 redis:2.8.21
2 在VirtualBox下配置端口映射
3 下载Redis客户端管理软件
下载地址
https://github.com/caoxinyu/RedisClient
运行界面
二 新建项目
新增依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
三 新建领域模型
//此类必须实现序列化接口,因为使用Jackson做序列化需要一个空构造函数。
package com.wisely.ch8_6_2.dao;
import java.io.Serializable;
public class Person implements Serializable{
private static final long serialVersionUID = 1L;
private String id;
private String name;
private Integer age;
public Person() {
super();
}
public Person(String id,String name, Integer age) {
super();
this.id = id;
this.name = name;
this.age = age;
}
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;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
四 数据访问
package com.wisely.ch8_6_2.domain;
import javax.annotation.Resource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Repository;
import com.wisely.ch8_6_2.dao.Person;
@Repository
public class PersonDao {
@Autowired
StringRedisTemplate stringRedisTemplate; //Spring Boot已为我们配置StringRedisTemplate,此处可以直接注入
@Resource(name="stringRedisTemplate")
ValueOperations<String,String> valOpsStr; //@Resource注解指定stringRedisTemplate,可注入基于字符串的简单属性操作方法
@Autowired
RedisTemplate<Object, Object> redisTemplate; //Spring Boot已为我们配置了RedisTemplate,此处可直接注入
@Resource(name="redisTemplate")
ValueOperations<Object, Object> valOps; //@Resource注解指定redisTemplate,可注入基于对象的简单属性操作方法
public void stringRedisTemplateDemo(){ //存储字符串类型
valOpsStr.set("xx", "yy");
}
public void save(Person person){ //存储对象类型
valOps.set(person.getId(),person);
}
public String getString(){//获得字符串
return valOpsStr.get("xx");
}
public Person getPerson(){//获得对象
return (Person) valOps.get("1");
}
}
五 配置
@SpringBootApplication
public class Ch862Application {
public static void main(String[] args) {
SpringApplication.run(Ch862Application.class, args);
}
@Bean
@SuppressWarnings({ "rawtypes", "unchecked" })
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)
throws UnknownHostException {
RedisTemplate<Object, Object> template = new RedisTemplate<Object, Object>();
template.setConnectionFactory(redisConnectionFactory);
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
template.setValueSerializer(jackson2JsonRedisSerializer); //设置值的序列化为jackson2JsonRedisSerializer
template.setKeySerializer(new StringRedisSerializer()); //设置键的序列化为StringRedisSerializer
template.afterPropertiesSet();
return template;
}
}
六 控制器
package com.wisely.ch8_6_2.web;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.wisely.ch8_6_2.dao.Person;
import com.wisely.ch8_6_2.domain.PersonDao;
@RestController
public class DataController {
@Autowired
PersonDao personDao;
@RequestMapping("/set") //设置字符及对象
public void set(){
Person person = new Person("1","wyf", 32);
personDao.save(person);
personDao.stringRedisTemplateDemo();
}
@RequestMapping("/getStr") //获得字符
public String getStr(){
return personDao.getString();
}
@RequestMapping("/getPerson") //获得对象
public Person getPerson(){
return personDao.getPerson();
}
}
七测试
1 浏览器输入:http://localhost:8080/set
字符串存储如图:
对象存储如图:
2 获得字符
浏览器输入:http://localhost:8080/getStr
3 获得对象
