如何自动装配 RedisTemplate<String,Object>

Question

我想在 Spring Boot 中使用 RedisTemplate。我可以成功使用StringRedisTemplate，但无法使用RedisTemplate。这是代码。

\n\n

@RunWith(SpringRunner.class)\n@SpringBootTest\npublic class RedisEntityTests {\n\n    @Autowired\n    private StringRedisTemplate stringRedisTemplate;\n\n    @Autowired\n    private RedisTemplate<String, RedisEntity> redisTemplate;\n\n    // This test case can run successfully.\n    @Test\n    public void testString() {\n        // save string\n        stringRedisTemplate.opsForValue().set("aaa", "111");\n        Assert.assertEquals("111", stringRedisTemplate.opsForValue().get("aaa"));\n    }\n\n    // This test case I got error.\n    @Test\n    public void testObject() throws Exception {\n        // save object\n        RedisEntity redisEntity = new RedisEntity("Tom", 20);\n        redisTemplate.opsForValue().set(redisEntity.getName(), redisEntity);\n\n        Assert.assertEquals(20, (redisTemplate.opsForValue().get("Tom")).getAge().longValue());\n    }\n}\n

然后，运行测试方法\xef\xbc\x9atestObject()，这里是错误报告\xef\xbc\x9a

您还没有定义要用于在 RedisTemplate 中注入的 Bean。您可以通过创建配置文件来解决它。

@Bean
    JedisConnectionFactory jedisConnectionFactory() {
        return new JedisConnectionFactory();
    }

    @Bean
    RedisTemplate< String, Object > redisTemplate() {
        final RedisTemplate< String, Object > template =  new RedisTemplate< String, Object >();
        template.setConnectionFactory( jedisConnectionFactory() );
        template.setKeySerializer( new StringRedisSerializer() );
        template.setHashValueSerializer( new GenericToStringSerializer< Object >( Object.class ) );
        template.setValueSerializer( new GenericToStringSerializer< Object >( Object.class ) );
        return template;
    }
