crucible annotations

The annotations in spring can be divided into two main categories:1) Spring bean Container-related annotations, or bean factory-related annotations;2) SPRINGMVC related annotations.Spring's bean container-related annotations are: @Required, @Autowired, @PostConstruct, @PreDestory, and the JSR-330 standard that Spring3.

Spring Framework Learning (v) annotationsAnnotation Annotation, which is a kind of annotation-like mechanism, adds annotations in code that can be used at a later time. Unlike annotations, annotations are for us, theJava virtual machine does not compile, the annotations are not compiled, but we can read the information

transaction management is built on the AOP. The essence is to intercept the method before and after it, and then create or join a transaction before the target method starts, committing or rolling back the transaction according to execution after the target method is executed. The greatest advantage of declarative transactions is that you do not need to programmatically manage transactions, so that you do not need to doping transaction-managed code in your business logic code, just make relevan

Use of Java annotationsOriginal: http://www.cnblogs.com/pepcod/archive/2013/02/16/2913474.htmlAnnotations (also known as metadata) have a simple syntax that is basically consistent with Java's inherent syntax, in addition to the use of the @ symbol. Java SE5 contains three types of annotations defined in Java.lang:(1) @Override(2) @Deprecated(3) Supresswarings: Improper compiler warning message is turned off.Java also provides four additional

since JDK1.5 introduced @override, @Deprecated. @SuppressWarnings these three annotations and their own definition annotations, the annotations begin to develop in full swing. Today, many frameworks support annotations, and annotations make our code look more concise and, to

To start using annotations in your project, make sure that the jar files in the Webcontent/web-inf/lib folder include the following: Struts2-convention-plugin-x.y.z.jar Asm-x.y.jar Antlr-x.y.z.jar Commons-fileupload-x.y.z.jar Commons-io-x.y.z.jar Commons-lang-x.y.jar Commons-logging-x.y.z.jar Commons-logging-api-x.y.jar Freemarker-x.y.z.jar Javassist-.xy.z.ga Ognl-x.y.z.jar Struts2-core-x.y.z.jar Xwork-core.x

Reprint https://www.cnblogs.com/acm-bingzi/p/javaAnnotation.htmlBrief introductionShould this be a problem for many first-time contact developers? Annontation is a new feature introduced by Java5, the Chinese name is called annotation. It provides a secure, comment-like mechanism for associating any information or metadata (metadata) with program elements (classes, methods, member variables, and so on). Add a more intuitive and straightforward description of the program's Elements (classes, meth

Understanding AnnotationsAnnotations are java1.5,jdk5.0 referenced techniques, with classes, interfaces, and enumerations at the same level. It can be declared in front of packages, classes, fields, methods, local variables, method parameters, and so on, to explain these elements, comments.In Java, there are three annotations, these three annotations exist in the Java.lang package, first of all we talk abou

The simplest understanding, the annotation is the same as the label, is the interpretation of abstract things;It's looking at http://blog.csdn.net/briblue/article/details/73824058.Blog When the first summed up a sentence but after reading the feeling annotation is a label but he is also a declaration of a method or class, for example, this class is I write, I can put a label on it, affixed with my nameI'm going to use the question I was reading at the time to explain, first of all, we have to as
