Spring Boot单元测试中使用mockito框架mock掉整个RedisTemplate的示例

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")
@configuration
public 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。
