Spring 4 + jpa (hibernate 3/4) + spring mvc multi-data source configuration (2) + Druid connection pool, mvcdruid
Pick up a blog post (http://www.loveweir.com/html/18.html), no database connection pool, purely using the official link of jpa.
Therefore, we need to add the connection pool. In this article, we use the Druid connection pool to configure multiple data
details of the lower layer? This is a challenge for us. Here we will discuss an Integrated Framework Strategy (using three popular open-source frameworks): Presentation layer we use struts; business layer we use spring; persistence layer uses hibernate. You can also use other frameworks to achieve the same effect. See Figure 1 (Framework combination)

the transfer of control is called inversion. Dependency injection, in which the dependencies between components are determined by the container at run time, the image is that the container dynamically injects some kind of dependency into the componentThe main function is to decoupleThe role of struts, spring and hibernate in each layer1) Struts is responsible for the Web tier.Actionformbean receives the da
In Web projects, various web frameworks are generally used together, such as spring + hibernate, spring + ibatis, so that other frameworks are integrated into spring, A little inconvenience, of course, spring has made this integration very easy. I combined the
The previous blog has explained several common ways in which spring configures data sources. Next, this blog continues to explain. After configuring the data source, how does the DAO layer access the database?
Based on the most recent project using the SSH2 framework, the analysis summarizes the two common ways in which the DAO layer accesses the database after spring and
Next to a blog post, there is no database connection pool, purely with the official JPA link. So this time we're going to add a connection pool. This article uses Druid Connection pool to implement multi-data source configuration. Persistence.xml This file can be omitted, all configured in Applicationcontext.xml: other places do not need to be changed by the last configuration. That's good. reprinted from: Http://www.loveweir.com/html/19.htmlSpring 4+ JPA (

Franksoo is my project manager. Some time ago, the company decided to create a new J2EE secondary development platform to replace the company's original development platform. The company asked franksoo and I to form a platform development project team and franksoo as the project manager. Now the integrated development
mapped to the blobbytearraytype type provided by spring. blobbytearraytype is a user-defined data type, which implements the org. hibernate. usertype. usertype interface of hibernate. Blobbytearraytype saves byte [] data to blob database fields using the lob operation handle lobhandler obtained from sessionfactory. In this way, we no longer need to use a hard-co

I think the most important thing to learn about Spring is to integrate Spring + Struts2 + Hibernate. Spring is like a large container. After integrating struts2 and hibernate, the process is switched to spring's applicationContext. in the xml configuration file, paste the in
1. Manage sessionfactory
When we use spring to integrate hibernate, we do not need the hibernate. cfg. xml file. First, configure the data source bean and session factory bean in applicationcontext. xml. When configuring the session factory bean, the following information should be injected:
● Data source Bean
● Configuration files for all persistence classes
● A

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
