redis配置文件：
key序列化为String；
value序列化为json对象；
package org.example.config; 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.*; import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer; import org.springframework.data.redis.serializer.RedisSerializer; @Configuration public class RedisConfig { @Bean public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) { // 创建一个RedisTemplate对象 RedisTemplate<String, Object> template = new RedisTemplate<>(); // 设置连接工厂 template.setConnectionFactory(redisConnectionFactory); // 创建json序列化工具 GenericJackson2JsonRedisSerializer jsonRedisSerializer = new GenericJackson2JsonRedisSerializer(); //配置key序列化 template.setKeySerializer(RedisSerializer.string()); template.setHashKeySerializer(RedisSerializer.string()); //配置value序列化 template.setValueSerializer(jsonRedisSerializer); template.setHashValueSerializer(jsonRedisSerializer); return template; } }
POJO类：
package org.example.Entity; public class MyUser { private int id; private String name; public MyUser() { } public MyUser(int id, String name, int age) { this.id = id; this.name = name; this.age = age; } private int age; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } @Override public String toString() { return "MyUser{" + "id=" + id + ", name='" + name + '\'' + ", age=" + age + '}'; } }
controller：
package org.example.controller; import org.example.Entity.MyUser; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.web.bind.annotation.*; @RestController public class MyUserController { @Autowired private RedisTemplate<String,Object> redisTemplate; /** * 查询所有用户信息 * @return */ @GetMapping(value = "/get") public MyUser get() { redisTemplate.opsForValue().set("abc",new MyUser(10,"a",11)); MyUser s = (MyUser) redisTemplate.opsForValue().get("abc"); System.out.println(s); return s; } }
