PHP Management Dependency (dependency) Relationship Tool Composer Auto-load (autoload), dependencyautoload
For example, assuming that our project wants to use the Monolog log tool, we need to tell composer in Composer.json that we need it:
{"Require": { "Monolog/monolog": "1.*"}}
After execution:
PHP Composer.phar Install
OK, now that the installation is done, how to use it? Composer automatically generat
The following classes are designed to have editpsndocaction and refreshpsndocaction this two class,And the final effect I want is:The following explains the process "As shown: Because spring's dependency injection is used in the NC product. So I can call it this way. A bean that calls the refresh button directly、In the Editpsndocaction class, a way of using spring's dependency injection. Assigning a value
Unity is a dependency injection container, and natural dependency injection is its most important function. From previous discussions, contradictions have focused on unity's intrusion into the object of dependence, which may be the unity in the preview version of the document did not say, plus a foreign cow of an article caused by the consequences. Because Unity can also support non-invasive
First, Pcre installation
./configure--prefix=/usr/local/pcre-8.38--libdir=/usr/local/lib/pcre--includedir=/usr/local/include/pcre
--libdir=dir
Specifies the location where the library files are installed.
--includedir=dir
Specifies the installation location of the C header file. This option is also available for other languages such as header files for C + +.
Second, install zlib Library
./configure--prefix=/usr/local/zlib-1.2.8
Third,
installation
SSL
./config--prefix=/usr/local/openssl-1
Dependency-inversion principle
A. High-level modules should not depend on low-level modules. Both of them should depend on abstraction.
B. abstraction should not depend on details, but on abstraction.
The high-level module containsProgramImportant policy selection and business model in. it is these high-level modules that make all their applications different from others. if the upper layer depends on the lower layer, the changes to the lower lay
The construction of the Springboot project generally has the following dependencies:If you delete this dependency, it will appear as a problem:Workaround, introduce maven dependencies:J tested, packaged words, can not run, can not use Java-jar Demo.jar run, will error no master list.You must add the following pluginsAfter testing, packaging, using the command Java-jar Demo.jar project can start normally.Springboot project does not apply to parent
Composer will automatically look for Composer.json this file when it is in use. Composer.json will be used to define the dependency package for the entire project. For example:
{
"require": {"Monolog/monolog":
"1.2.*"
}
}
Depending on the package simple description, our project requires some Monolog/monolog packages starting with any version of 1.2.

Java reads Excel files without dependency, and java reads excel files with dependencySpeaking of Java reading Excel files, it is of course a lot of use POI or jxls, but when I read a book today, it is mentioned that the JdbcOdbcDriver driver class can also be used to read Excel files without relying on third-party libraries. I searched the internet for the reason and wrote an example and ran through, record it here.Java is familiar with reading databa
Because many jar packages are interdependent, it is easy to generate versioning problems when using MAVEN to build a project.
Problem: Compile compilation passed, but test tests or install after the program error
Tip method is not found, by looking at the class that throws the exception, you can see that the referenced class does not have this method, because when it is run, a different version of the jar package is referenced.
Workaround:
Step 1: Open Pom.xml through MyEclipse, open
version number of spring--also need to understand this very not intuitive fact, spring Security 3.1.x also does not rely on the spring 3.1.x version number ! This is because spring Security 3.1.x was announced prior to spring 3.1. Spring plans to keep these dependencies as consistent as possible in a future version number, and want to know a lot of other information to take a look at their Jira plan, but this is certainly not the case now, and we'll
Reproduced from a Sdn-4o4notfoundMany new features have been updated in Spring 4.0, and one of the more important is the support for dependency injection of beans with generics. This change in Spring4 allows the code to use generics for further refinement optimizations.1. Benefits of generic Dependency InjectionGeneric dependency injection allows us to use spring

Note: The classifier of the project cannot be defined directly, because the subordinate artifacts are not generated directly by default, but are generated by the additional plug-in Help.

Lightweight containers have recently been surging in the Java community, and these containers have been able to build a cohesive application from different projects. These containers are based on a common pattern, which determines how the container completes the assembly of components, which people call the "control inversion" "inve

Before I introduce the dependency properties, let me introduce the history of the propertiesAttribute history: Early C + + classes, only fields and methods, exposing the data is the method, but the direct exposure of the field is not safe, so the method to expose, in the setting of the time to add some constraints, in MFC is the case. However, in order to access a field, there are always set up and get two methods, too fragmented, not conducive to man
