需求:
替换redisTemplate中的默认序列化方式,可以不用强转得到指定对象
修改RedisConfig中的redistemplate@bean
@Bean(name = "stuRedisTemplate")
public RedisTemplate<String, Student> stuRedisTemplate(RedisConnectionFactory redisConnectionFactory){
log.info("objectTemplate");
RedisTemplate<String, Student> redisTemplate = new RedisTemplate<String, Student>();
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(Student.class));
//原本是GenericJackson2JsonRedisSerializer()
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
redisTemplate.setConnectionFactory(redisConnectionFactory);
return redisTemplate;
}
然后在调用处指定调用方式
@Resource(name = "stuRedisTemplate")
RedisTemplate<String, Student> redisTemplate;
@Test
public void test5() {
Optional<Student> optionalStudent = studentDao.findById(4);
Student student = optionalStudent.get();
log.info("student:{}", student);
redisTemplate.opsForValue().set("test-students:3",student );
Student student1 = redisTemplate.opsForValue().get("test-students:3");
//此处就不用强转,并且redis中的也是标准的json字符串,可读性也好
log.info("student1: {}",student1);
}
