JDK, JSON serialization and using Redis Hash type to save 50,000 user random objects to Redis

 

Configuration file:

                 <!-- jdk序列化 -->
 		 <!-- <property name="valueSerializer">
			<bean
				class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
		</property>  -->
		
		<!-- json序列化 -->
		<property name="valueSerializer">
			<bean
				class="org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer" >
				<constructor-arg value="java.lang.Object"></constructor-arg>	
			</bean>
		</property>  
		

		<!-- hash小键的序列化 -->
		<property name="hashKeySerializer">
			<bean
				class="org.springframework.data.redis.serializer.StringRedisSerializer" />
		</property>

		System.out.println("所用时间："+(t2-t1));
	}
}

Test Results:

The JSON serialization method has the shortest use time, and the JDK method has the longest use time
