概述

当我们使用单元测试来验证应用程序代码时，如果代码中需要访问Redis，那么为了保证单元测试不依赖Redis，需要将整个Redis mock掉。在Spring Boot中结合mockito很容易做到这一点，如下代码：

import org.mockito.Mockito;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.data.redis.connection.RedisConnection;import org.springframework.data.redis.connection.RedisConnectionFactory;import org.springframework.data.redis.core.*;import org.springframework.test.context.ActiveProfiles;import static org.mockito.Mockito.when;/** * mock掉整个RedisTemplate */@ActiveProfiles("uttest")@Configurationpublic class RedisTemplateMocker { @Bean public RedisTemplate redisTemplate() { RedisTemplate redisTemplate = Mockito.mock(RedisTemplate.class); ValueOperations valueOperations = Mockito.mock(ValueOperations.class); SetOperations setOperations = Mockito.mock(SetOperations.class); HashOperations hashOperations = redisTemplate.opsForHash(); ListOperations listOperations = redisTemplate.opsForList(); ZSetOperations zSetOperations = redisTemplate.opsForZSet(); when(redisTemplate.opsForSet()).thenReturn(setOperations); when(redisTemplate.opsForValue()).thenReturn(valueOperations); when(redisTemplate.opsForHash()).thenReturn(hashOperations); when(redisTemplate.opsForList()).thenReturn(listOperations); when(redisTemplate.opsForZSet()).thenReturn(zSetOperations); RedisOperations redisOperations = Mockito.mock(RedisOperations.class); RedisConnection redisConnection = Mockito.mock(RedisConnection.class); RedisConnectionFactory redisConnectionFactory = Mockito.mock(RedisConnectionFactory.class); when(redisTemplate.getConnectionFactory()).thenReturn(redisConnectionFactory); when(valueOperations.getOperations()).thenReturn(redisOperations); when(redisTemplate.getConnectionFactory().getConnection()).thenReturn(redisConnection); return redisTemplate; }}

上面的代码已经mock掉大部分的Redis操作了，网友想mock掉其他操作，自行加上即可。
