When using spring-declared transactions and spring-provided templates for the persistent layer to operate databases, in principle, do not write transaction control statements (COMMIT) in the code ).1. When jdbctemplate and JDBC are used for integration: public void testInsert(int id, String val) {this.jdbcTemplate.update("insert into A (ID, VAL) values (?, ?)", id, val);try {jdbcTemplate.getDataSource().ge

Spring Framework The Spring framework is a lightweight container that can be used in combination with many Web applications such as struts and webwork, or it can be used alone. First, the characteristics of spring: Face Tangent (aspect-oriented programming AOP), control rollover (inversion of control IOC) Lightweight:

Although I have read the book for a while, I can still feel that spring is very abstract.Introduction to Spring:leads to:Dependency Injection . The way is: constructor injection. (+ interface-oriented) for loose coupling.The behavior of creating collaboration between application components (objects) is called Assembly.

Spring is an open source framework that is a lightweight control inversion (IOC) and aspect-oriented (AOP) container frameworkReason:(1) Spring is lightweight in terms of size and overhead, and its capacity is small, and the cost

1, when loading the configuration file definition, determine which authenticationmanager to useWhen the configuration file Security.xml is loaded, a providermanager is created first, and thenIf you configured the default Authenauthmanager (HTTP attribute authentication-manager-ref), use the default as the parent of ProvidermanagerIf no default authenauthmanager (HTTP attribute authentication-manager-ref)

-oriented programming is provided in spring, allowing for the development of cohesion through the separation of application business logic with system-level services such as auditing (auditing) and transaction (transaction) management. The Application object only implements what they should do-complete the business logic-that's all. They are not responsible (or e

Today in the "Spring Technology Insider", the first chapter has repeatedly mentioned the use of Pojo to complete the development, Baidu a bit, in this reserve1.

to present the functions to be implemented in the form of test cases. This is similar to the way in rest to design the system structure through URL. We only need to design reasonable URLs as needed. These URLs do not have to be linked to the specified page or complete some actions, as long as they can intuitively display the user interfaces of the system. Based on these URLs, we can easily design the system structure. From the concept of the rest arc
