during operation. AOP: Plane-oriented programming AOP is the derivation of OOP, we are now object-oriented programming, we implement a module function is, the code is written as follows: Public class objecta{ publicvoid dosomething () { connbegin (); Tranbegn (); Dobesiness (); Tranend (); Connend (); }}In the above code, we can see that Connbegin () and Connend () are links and close links, Tranbegn () and Tranend () are the start and

spring is a lightweight Java development framework that emerged in 2003 by Rod Johnson in his book expert one-on-one development and Some of the concepts and prototypes elaborated in design are derived. It is created to address the complexities of enterprise application development. Spring uses basic JavaBean to accomplish things that were previously only possib

In the Java session, a bull named Rod Johnson found that the initial Java enterprise-level development was in a state of chaos. As a result, it is determined to write a common infrastructure that solves the problem. Because it is convinced that interface-oriented programming can control change to the minimum, but also conducive to expansion and change. As a result, it writes the following interface. In

So far, the basic framework of SSH has been built, and now, on top of that, with the authority control, which is the spring security framework, as in the previous order, first see which libraries need to be added.1. Pom.xmlSpring security only needs to add its own library to define the properties of a version:Properties> spring.version>4.0.4.RELEASEspring.version> hibernate.version>4.3.5.Finalhibernate.version>

development framework that emerged in 2003, it is derived from part of the concepts and prototype stated by Rod Johnson in his book "Expert One-On-One J2EE Development and Design. It is created to solve the complexity of enterprise application development. Spring uses the basic JavaBean to complete the previous tasks that may only be completed by EJB. However, Spring is not only used for server-side develo

I recently applied the Java RMI technology, so I will summarize the use of RMI. In addition, the implementation of EJB is also based on Java RMI. RMI remote method calls can be called across machines through the network, but Java RMI only supports Java programs on both sides. To achieve completely heterogeneous on both

, because it does not involve compilation, where one bean only needs to declare ' ref= ' Somebean "', leaving the rest to spring to be processed during container initialization. Of course, when using the @configuration class, the Java compiler has some limitations on configuration patterns, and references to other beans must be legitimate

:@RequestMapping ("/json") @ResponseBody public list json () { return userservice.getallusernames ();}Spring's role here is to inject the userservice needed by HomeController, run the program, and access the Http://localhost:8080/demo4springmvc-spring/json:["Zhangsan", "Lisi", "Wangwu"]SOURCE downloadAnother feature of spring is that AOP is not needed, and so on when the log is required to write, of

I. The xml configuration of spring is poor. XML abuse has been rampant. You need to know Program The most popular is reading. Code . When looking at a business logic, I found that I had to look at its parent class first, then the grandfather class, and then the grandfather class. Finally, I found that I still needed to find another class through spring configuration, when this class ref has another class,

Laravel makes many features easy, from security to scale and speed. This makes the Java framework awkward, such as spring MVC, which covers a lot of features, but is less developed than Laravel.

the property. Of course, this write will not distinguish the local and bean attributes in the ref element. In addition, if the bean property value is a set, you need to use the set element, Next we will transform a previously written com/sep/basic/service/impl/Lenovo class, which will contain multiple set attributes. 1 package com. sep. basic. service. impl; 2 3 import java. util. list; 4 import
