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;

									  }

									}
