First, we'll write a custom annotationthen we declare three classes to testFirst, declare an abstract parent class in declaring two subclasses, inheriting from our parent classSon Sub-categoryDaughter sub-classThe next step is to finish writing our functional class .Test ResultsA small example of annotation injection of the IOC implementation of spring

In order to be in the computer is not connected, the writing label in Beans.xml has the prompt function, need to import the constraint file locally on the computer, belowNote: Add the location suffix to the back of beans in keyNote: The method of importing the CONTEXT,AOP,TX constraint is consistent with the import beans method, notThis is four constraints all import success!!!Next, write the constraint to the XML configuration file and write the root element beansOther constraints import XML in

This example describes the Java Development Spring Connection database method. Share to everyone for your reference, specific as follows:Interface: Package cn.com.service; Import java.util.List; Import Cn.com.bean.PersonBean; Public interface Personservice { //Save the public void Save (Personbean); Update public void update (Personbean person); Gets the person public Personbean Getpe

the program execution process, so also no longer draw sequence diagram.2, attention to the example of the IOC, the use of Di is based on Reportservice for the client (that is, the component requirement), while the test code in the client class main () in the code is the end user of the service component, but it needs not the component but the service that the component has.3, actually in the spring box, in

Using the underlying API: RedisConnection operation of Redis requires manual conversion of data ( String ), which requires most repetitive work and is inefficient; org.springframework.data.redis.core.RedisTemplate classes provide a high level of abstraction for interacting with Redis, which is responsible for serialization and connection management, encapsulating most of the repetitive work. And RedisTemplate is a thread-safe class.In addition, the template provides an operation view for handli

Using JUnit to test an example of a spring static factory instantiation Bean, all the code is fine, but there is a java.lang.IllegalArgumentException exception,As shown in the following:　　began to think that the code is wrong, find out, the code is not a problem, the original JDK version is too high, modify the JDK version of the project, reduce the version from 1.8 to 1.7, as shown in:　　Test, success, as s

Excerpt from the Spring Handbook, an example of dependency injection The following example uses Xml-based configuration metadata for setter-based DI. A small part of a Spring XML configuration file specifies some bean definitions:

Take Jdkregexpmethodpointcut as an example to show how to use a static pointcut using a complete example (see routine 4.3 for the complete engineering code). In engineering we define a people class and a slice, and link them to the spring XML configuration file. When the People object executes the method defined in our pointcut, the logerpeople will give the appr

Mybatis can be used in two ways: Use mapper for database operations; Use sqlsession for database operations; In fact, the 1st types are encapsulated on the basis of the 2nd types, mainly providing interface method extraction and parameter conversion, sqlsession is still used to add, delete, modify, and query databases. The following is an example of using spring without integration: (1) User bean carry

Implementation example of oau2logout in Spring Cloud, cloudoau22. Next, we will implement the oau2's logout Function Based on Spring Cloud based on the implementation of oau2's authentication and authorization. 1. added a custom logout Endpoint. The so-called deregistration only needs to invalidate access_token and refresh_token. We mimic org. springframework.
