bean overflow

With the applicationProgramAs the scale increases, the growth of spring configuration files is faster. When there are more and more components in the application, the bean configuration in the spring configuration file also increases greatly, and a phenomenon will gradually emerge: a large number of bean configurations are identical, only a small number of configurations are different. Is there a way to sim

This blog focuses on the life cycle of the different beans provided by CDI and how they are used in the project.IntroductionWhen a bean is initialized by CDI, the Bean usually has its own scope. The scope given to it usually determines the entire life cycle of the bean. The life cycle of the bean provided by CDI:

Introduction to bean Validation Framework write bean Validation standardizes constraint definition, declaration and Validation for the Java PLATFO Rm.The general meaning is: Bean Validation standardizes the definition, description, and validation of constraints on the Java platform.For more information, please refer to: http://beanvalidation.org/

Scope of Bean in spring:In the spring container, the scope of the bean is by default a single mode, Singleton, and the single case pattern can be accessed concurrently by multiple threads, if We want to change the scope of the bean and change it to multiple patterns, that is, each time you get the same bean from the co

-time use, it is easy to memory overflow; Therefore, a better solution is to add the Applicationcontextaware implementation class Springcontextutil to the spring configuration file, Let spring do a service or DAO bean initialization at initialization time, so that the util can be used to get the initialized instance in the job, instead of creating the context each time. Package com.framework.util; Import

The scope of scope is studied today. The default is the singleton mode, which is scope= "singleton". In addition, scope also has prototype, request, session, global session scope. Scope= "prototype" multiple examples. When you configure the scope of the bean, its header file is as follows:How to use the scope of spring:id= "role" class= "Spring.chapter2.maryGame.Role" scope= "Singleton"/> This scope is used to configure the scope of the spring

Use the @Autowired to eliminate the set, get method.

Basic concepts Automatic assembly (Autowire) means that the entire assembly process is automatically completed and is no longer specified by US manually. There are several ways to assemble automatically in Spring: The name specification no means no automatic assembly, at which point you must manually specify the dependent bean byname to automatically assemble based on the property name, which checks the entire container for the same
