Redis causes the spring boot project unit test to fail to start

Background and usage scenarios

Redis is a product of the development of the Internet, as a key-value efficient storage system, providing efficient solutions for Internet applications. Redis is developed based on the C language, and provides basic data structures list, set, map, and supports many languages ​​such as java, c++, .net and so on. The data stored by redis is generally stored in memory, which speeds up the reading speed.

The application of redis is unlimited. According to its characteristics, you can imagine an unlimited number of application scenarios. The following are the frequently used scenarios:

1. Used as a cache, many people use this solution when the number of concurrent websites is large, including the cache of persistent data, including the cache of stateful data.

2. Queuing for use. Many websites have the function of flashing and snapping up purchases. This function is very instant and requires an efficient mechanism. When releasing inventory, you can store inventory information in redis, so that redis will be reduced after users purchase. Will not cause short-term blockage.

3. Asynchronous communication, with service A as the producer and service B as the consumer, which can replace bulky webservice or http and efficiently serve as the communication between services.

4. Logging, using redis and logstash to deal with the problem of distributed logging system. The logstash agent collects logs and sends them to redis, and another central logstash reads logs from redis for centralized processing.

Of course, there are more usage scenarios in reality, and use your imagination.

     A project requires the use of data caching, so redis is used. But after adding redis to the project, there is no problem with the function, but the unit test code written before can not run. (The code and error are posted, as follows, and can be ignored)

solve

Find the solution from the spring-boot document, it is very simple, SpringBootTest adds webEnvironment parameter.

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

You can use the above methods to solve such problems! !
