list of beans

A session bean represents a short session with the client program and may perform database read/write operations. A session bean may call JDBC by itself, or it may use entity bean to complete this call. In this case, the session bean is the customer of the Entity Bean. The domain of a session bean contains the session state and is short-lived. If the server or client program crashes, the Session Bean will be lost. This mode is usually used in database programming languages such as PL/SQL.An enti

Bean's definition inheritanceThe bean definition can contain a lot of configuration information, including the constructor parameters, property values, such as initialization methods, static factory method names, and other containers specific information. The child bean definition inherits configuration data from the parent definition. A child's definition can overwrite some values, or add additional as needed. The Spring bean defines inheritance regardless of the inheritance of the Java class

When the spring bean is configured, a singleton bean may appear dependent on a prototype bean. Because singleton beans have only one chance of initialization, their dependency pages are only set at initialization time, and at this point they initialize a prototype bean. This will lead to the prototype Bean became singleton, this contradictory solution has two:1. Discard the use of dependency injection and take the initiative to apply to the container

IOC IOC, the official definition is to rely on injection (Dependency injection) or control reversal (inversion). It's hard to understand the literal. But any mode is from people's behavior thinking way, as long as the imagination of the day-to-day production process, before the production is the customer orders, the list will specify the required products, including the product specifications of the attributes, and then the factory production. IOC is

enterprise|j2ee| Chinese translation: Software Institute Huang 1 Introduction. Enterprise Beans is part of the Java EE implementation of Enterprise JavaBeans (EJB) technology, which runs in the EJB container. EJB is the Run-time environment (Runtime environment) of a Java EE server. Although the EJB container is transparent to enterprise application developers, it provides services at the system level, such as enterprise

. If multiple construction methods have non-required annotation parameters, they will be candidates for automatic binding. Construction methods with a large number of dependencies can be constructed by matching beans in the spring container, and the default constructor is used if no candidate satisfies the criteria. The annotation constructor is not necessarily public.Field injection is done after the method is configured, this configuration field doe
