Spring boot also provides automatic configuration support for the JMS (Java message Service,java message Service), which mainly supports JMS implementations such as ACTIVEMQ, Artemis, and so on. Here take ACTIVEMQ as an example.First, the use of embedded ActiveMQ1. Add Activemq Start dependencyAdd Activemq dependency information to the pom.xml of the project: org.springframework.boot

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

1, what is Spring boot. With the popularity of dynamic languages (Ruby, Groovy, Scala, node.js), Java development is particularly cumbersome: a wide range of configurations, inefficient, complex deployment processes, and third-party technology integration are difficult. To address the above issues, Spring Boot is lau

In our actual work, there is always the need to do some initialization when the project starts, such as initializing the thread pool, loading the encryption certificate in advance. Today we will introduce a Spring boot artifact, specifically to help you solve the project start initialization resource operation.The artifact is CommandLineRunner that the CommandLineRunner interface Component will be

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

Spring boot also encapsulates the NoSQL database by automating the usual database support.About RedisRedis is the most widely used memory data store in the industry today. Supports a richer data structure than memcached,redis, such as hashes, lists, sets, etc., while supporting data persistence. In addition to this, Redis also provides some features of the class database, such as transactions, HA, and maste

1. "Failed to process import candidates for configuration class [Com.simple ...]":Main reasons:This is because your custom starter is packaged with Spring-boot-maven-plugin, which is configured in the Pom.xml of your custom starter project:This type of package, is based on the spring boot packaging, classpath settings,

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

When we are doing Web applications, it is very common for errors to occur during request processing. Spring Boot provides a default mapping: When an exception is thrown in processing, it is /error forwarded to the request for processing, and the request has a global error page to display the exception content.Choose a previously implemented web App (Chapter3-1-2) to start the app, access a nonexistent URL,

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
