To learn more about starting a transaction with spring, let's take a look at this simple example:1. entity class user. Java Package Org. lab24.entity; 2. Abstract DAO class. Here it is set as an abstract class mainly to prevent it from directly instantiating objects (this design seems a bit redundant here. This should be a design pattern ): Package Org. lab24.dao; 3 DAO implementation class: Package Org

The Mapfactorybean class provides developers with a way to create a specific Map collection class (HashMap and TreeMap) in the Spring bean configuration file. Here is a mapfactorybean. For example, at run time it instantiates a hashmap and injects it into a bean property.Package Com.yiibai.common;import Java.util.map;public class Customer {private Map maps;//...}Spring's bean configuration file.In addition,

Example of an IOC in springThe approximate contents of the project are:When one is in China, greet everyone in Chinese, and greet everyone in English when they are abroad.whichIhellomessage is an interface used to define output greeting information Public Interface ihellomessage { public String SayHello ();}HelloWorld is an implementation class for an interface that outputs Hello world information to the user Public class Implements ihellomessage {

This example describes the basic management of spring beans. Share to everyone for your reference, specific as follows: One, using setter method to complete dependency injection The following are the beans and beans-config.xml files. public class Hellobean { private String Helloword; //... Omit getter, setter method } public class Springdemo {public static vo

Recently studied spring + IBATIS. It is one thing to find examples of others, and to write a complete application is another matter. I'm fed up with the smattering code posted online. Ibatis is a persistence framework that covers SQL procedures, although SQL statements need to be written by themselves. In addition, I think for beginners, the complete example is really important, otherwise I do not know if t

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

Spring MVC 3 is the simplest example. I recently reviewed springMVC and tried to find another demo online. It seems that domestic demos are too complicated. Later, I found a simple spring mvc demo on a foreign website. Here I will record it and give it to anyone who needs it. Step 1: Prepare the package: Log packages Jcl-over-slf4j-1.6.1.jarLogback-classic-0.9.29
