Method One: How to load some initialization data that is needed for startup.To solve this problem, spring Boot provides a way for us to implement the interface Commandlinerunner. No additional configuration is required, so just create a class to implement the interface Commandlinerunner. After the Spring

Spring Boot RestTemplate: three methods for submitting form data: springresttemplate In the REST interface design, using RestTemplate for interface testing is a common method, but in the process of use, due to the large number of method parameters, many people confuse the differences between the form submission and Payload submission methods, and the interface de

The Redis cache data used in Spring can be directly manipulated via redistemplate or @cacheable annotations (as described in another article: Spring cachable key definition and application). Regardless of the method used, the key, value is serialized into a byte array, or a string is saved. Redistemplate source code ca

If we want to use a third-party JSON parsing framework in spring boot:1) We need to introduce third-party package dependencies in the Pom.xml file;2) Implementation method:Method 1 requires inheriting the Webmvcconfigureradapter class in the startup class and overriding the Configuremessageconverters method of the class.Method 2. We use @bean to inject third-party analytic frameworks directly.1, the introdu
