Redis 简单案例
1.在pox.xml中添加对Redis的依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
2.添加一个实体对象Person
//必须序列化对象
public class Person implements Serializable{
private String name;
private String password;
private int age;
public Person() {
super();
}
public Person(String name, String password, int age) {
super();
this.name = name;
this.password = password;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
3.添加一个PersonDao
@Repository
public class PersonDao {
// @Autowired
// StringRedisTemplate stringRedisTemplate; //1
private StringRedisTemplate stringRedisTemplate;
public StringRedisTemplate getStringRedisTemplate() {
return stringRedisTemplate;
}
public void setStringRedisTemplate(StringRedisTemplate stringRedisTemplate) {
this.stringRedisTemplate = stringRedisTemplate;
}
@Resource(name = "stringRedisTemplate")
ValueOperations<String, String> valOpsStr; //3
@Autowired
RedisTemplate<Object, Object> redisTemplate; //2
@Resource(name = "redisTemplate")
ValueOperations<Object, Object> valOps; //4
public void stringRedisTemplateDemo() { //5
valOpsStr.set("xx", "dairui");
}
public void save(Person person) { //6
valOps.set(person.getName(), person);
}
public String getString() {//7
return valOpsStr.get("xx");
}
public Person getPerson() {//8
return (Person) valOps.get("1");
}
}
4.创建DataController类
@RestController
public class DateController {
@Autowired
PersonDao personDao;
@RequestMapping("/set") //1
public void set(){
Person person = new Person("1","wyf", 32);
personDao.save(person);
personDao.stringRedisTemplateDemo();
}
@RequestMapping("/getStr") //2
public String getStr(){
return personDao.getString();
}
@RequestMapping("/getPerson") //3
public Person getPerson(){
return personDao.getPerson();
}
5.Application类
@SpringBootApplication
public class RedisApplication {
public static void main(String[] args) {
SpringApplication.run(RedisApplication.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); //1
// template.setKeySerializer(new StringRedisSerializer()); //2
//
// template.afterPropertiesSet();
// return template;
// }
}
