Preparation of the project Use the source code of the previous section directly, Spring Boot tutorial (vii): Spring Boot integrated druid connection pool For convenience, the following sections no longer modify the package name and the startup class name according to the chapter content, so the source code for the

Spring Bootis a new framework provided by the pivotal team, designed to simplify Spring the initial construction and development of new applications. The framework uses a specific approach to configuration, which eliminates the need for developers to define boilerplate configurations. In this way, boot is committed to becoming a leader in the burgeoning field of

database connection pool selection algorithm By default, database connections can be configured automatically using the DataSource pool. Here is an algorithm for selecting a specific implementation: because of the performance and concurrency of the Tomcat data source connection pool, we always use it preferentially when Tomcat is available. If HIKARICP is available, we will use it. If Commons DBCP is available, we will use it, but it is not recommended in the production environment. Finally, if

way the spring application is developed.Spring Boot Starter: It consolidates common dependency groupings and merges them into a dependency so that they can be added to the project's Maven or Gradle build at once ；automatic configuration : Spring Boot's auto-configuration feature leverages

Springboot officially recommends that we use spring-boot-starter-parent. spring-boot-starter-parent contains the following information: 1. Use Java 6 for compilation 2. UTF-8 encoding 3. implemented a general testing framework (JUnit, Hamcrest, Mockito ). 4. SMART Resource Filtering 5. intelligent plug-in configuration

Classes that overwrite Auto-configuration Dynamic configuration with external properties "this article" Customizing the Error page "second article" The automatic configuration of Spring boot can save a lot of uninteresting configuration work, but not all automatic configuration can meet the requirements. For example, when you link a database, you need to use some or-mapping middleware, such as

integrity constraints that are defined on the data. Isolation (Isolation): There may be multiple transactions executing concurrently in the same environment, and each transaction should be performed independently. The effect of serially executing a series of transactions should be the same as executing them concurrently. This requires two things: During the execution of a transaction, the intermediate (possibly inconsistent) state of the data should not be exposed to all other transactions. T

, it is cumbersome to configure a fully available (web) environment, such as the need to configure logs, databases, caches, etc., and then configure Tomcat, Finally, publish the program to the Tomcat directory. Spring boot helps us greatly simplify this process by providing a lot of starter, as long as the corresponding jar package is introduced. For example, we need to integrate Tomcat, just to introduce T
