+ hibernate, while my idea was tapestry + hibernate.However, franksoo is very open. After I showed him the typical sample workbench of tapestry and introduced the component-based programming method of tapestry, he agreed to use Tapestry as the framework for implementing the WEB presentation layer. I think franksoo's previous struts development experience (painful) is also one of the factors for his decision. Franksoo gave me a nice introduction of

PrefaceEncountering a problem with the user experience in development, each time an operation is updated to restart the server, it causes the logged-in user of the membership platform to be dropped. This is because the session information and status of each user are saved by a session, and the session object is created by the server, and the

: Data is not modified by third parties, data size is acceptable, data update frequency is low, the same data is frequently used by the system, non-critical datac) Implementation of third-party cachesFirst-level caching: Session-level caching is also called transaction-level caching, caching entities only, the lifecycle and session consistency. It cannot be managed.No calls are displayed.Second level cache:

Simple Example of Spring Session to implement distributed session, springsession example Previously, tomcat-redis-session-manager was used to implement distributed session management, but it has some limitations, mainly because it is too tight to bind with tomcat, here, we u

Spring Integration Hibernate1 What exactly is integrated?I: In order to let spring's IOC container to generate sessionfactoryII: In order for Hibernate to be able to use spring's declarative transactions2 How to integrate (integration steps)1 Add hibernate must jar package, then add Commons-logging-1.1.3.jar, and MySQL jar package Mysql-connector-java-5.1.7-bin.j

directly inherit the spring-to-Hibernate wrapper class Hibernatedaosupport, and then use this class to provide such things as saveorupdate (), Saveorupdatecopy (), and find () and so on. In addition, hibernate classes, such as query, Session, type, are also used when implementing some of the more complex

Why use the Hibernate framework? This is already mentioned in the hibernate introduction blog. Since the Hibernate framework is used to access and manage the persistent layer, why does spring be used to manage and integrate hibernate? First, let's take a look at the

About session sharing, there are a lot of articles on the Internet, but very few articles are others have seen, can be practical operation can be realized, I do not know what is missing out of the article or what reason, may be my ability to not reach the required capacity of the article required it. Regardless of the number, I'll take the actual configuration of the installation deployment instance to tell me how to implement

Spring configuration file so that SessionFactory can process Lob data. Reference the bean in SessionFactory: 2. Use native Hibernate API By injecting SessionFactory, we can directly get the Session bound to the current thread through getCurrentSession. Hibernate has the ability to obtain the

already supports hibernate, this example inherits the hibernatedaosupport class directly. This class is very useful. We can refer to hibernatetemplate (which is mainly used for hibernatedaosupport: for details, refer to the srping API ). The Dao interface code is as follows: Code: Public interface iorderdao {Public Abstract Order findorderbyid (Final int ID );Public abstract list findordersplacebyuser (Final string placedby );Publ

reduces the number of database operations and provides better running performance . Customer customer =NewCustomer (); customer =NewCustomer ();//First set the attributes of the customer object, and then save its session. Save (customer );Customer. setname ("Tom ");//Save the customer object and modify its attributes.Session. Save (customer); customer. setname ("Tom"); Transaction. Commit (); transaction. Commit (); // clear the cache at this time

components. The Spring dao:jdbc DAO Abstraction Layer provides a meaningful exception hierarchy that can be used to manage exception handling and error messages thrown by different database vendors. The exception hierarchy simplifies error handling and greatly reduces the number of exception codes that need to be written (such as opening and closing connections). Spring DAO's JDBC-oriented exception co

Today, when I was learning Shiro, I built a springmvc+spring+hibernate integration framework, and then I made an error when I ran the one-many,many-one mapping relationship with lazy loading. Could not initialize proxy-no the session and then went on the internet to find data, which means that since Hibernate and

Know it, but also know why. This article describes the principle of the entire implementation of spring-session. And the core of the source code for a simple introduction. Introduction to the principle of realization Implementation principle here is a brief description: When the Web server receives the HTTP request, and when the request enters the corresponding filter, the process that originally needs to b
