First, prefaceSome time ago, the company has an app project needs to support different platforms, so the use of Ionic2 + Cordova + ANGULAR2, in the process of building the environment encountered a lot of problems, just recently have time to sort out.Second, the development environment constructionRefer to this site steps to build:Https://github.com/DonaldTdz/Ionic2QuickStartNote: Nodejs to install 6.0 +lts the latest version, do not install 8.

In the ANGULAR2 framework of the general Interactive parsing JSON is to use the service, in fact, in addition to the service is still a lot of, today first write the simplest front-end data interactionHmm ~ ~First, I'll create the service directly under the app package.All rightWhat about here? Angular2 has a well-encapsulated HTTP interface directly referenced (to, here HTTP seems to have been abolished,,

1. IntroductionLogger is one of the three core carriers of Log4net, and it is of great significance to make it clear. The other two were Appender and Layout. The corresponding relationship is one logger corresponding to multiple appender, and one appender corresponds to one layout.For the internal implementation of Log4net, ILogger is the interface (all logs need to be implemented--interface that all loggers implement).Why not the ILog interface we us
log4j: Specify the output level of a logger individually--
Generally for production systems, log levels are adjusted to info to avoid excessive output logs.But at some point, you need to keep track of specific issues, so you have to turn on the debug log.But if you open the Log4j.rootlogger, the information you need will be submerged in the log ocean.At this point, you need to specify that a log level of one or some
Recent tasks often involve log records, and have been deliberately logging to learn how to record them again. Like Java, Python's logging is a tedious thing, writing a lot of things before writing a record. The procedure for typical logging is this:
Create Logger
Create Handler
Define Formatter
Add formatter to Handler
Add handler to Logger
The code is almost the same as the sa

A sample code that uses Java.util.logging.Logger for log output is as follows:
Package com.sample; Import Java.io.File; Import Java.util.logging.FileHandler; Import Java.util.logging.Handler; Import Java.util.logging.Level; Import Java.util.logging.Logger; Import Java.util.logging.SimpleFormatter; public class Loggersample {protected Logger Log=logger.getlogger (This.getclass ().

Logging via Logger commandLogger is a shell command interface that allows you to use Syslog system log modules and write a line of information directly from the command line to the system log file.----------------------------------------------------------Logger syntaxlogger [options] [messages]**options (option): * *-D,--UDPUse datagram (UDP) instead of using the default stream connection (TCP)-I.,--idRecor
Before learning the use of the Logger module, you can customize a logger implementation to both file and screen output. However, when using the Software Catalog development specification to organize the code, it is necessary to make the code a block of code, and a series of problems are encountered.The first is an example of a custom logger:importlogging# first create a Loggerlogger=logging.getlogger (__nam

The significance of logstore in programs of medium size or above is needless to say, especially in some parallel programs, it plays a "De
By the name of logger can know the meaning of this sentence is to use the Logger factory to obtain logger instance, but do not understand the principle, looked at the source code:
The GetLogger method in Loggerfactory returns an instance of a static binding named after name, which is typically named after the class in which the
Excerpt from official documentation: that is, logger is a subclass of category, with more functions than the parent class
Logger is a subclass of category, i.e. it extends category. In the other words, a loggeris a category. Thus, all operations The can is performed on a category can is performed on a logger. Internally, whenever log4j is asked to produce a Categ
3 Complete Solutions
Sunny company developers decided to use the factory method model to design the logger, the basic structure of which is shown in Figure 3:

In Figure 3, the Logger interface acts as an abstract product whose subclasses FileLogger and Databaselogger act as specific products, and the Loggerfactory interface acts as an abstract factory, Its subclasse
If the required UI control does not require any other detailed controls, that is, it only encapsulates HTML elements of a certain part, but also listens to the size, size, and layout control provided by the layout manager, the extension object is Ext. boxcomponent. For example, if a logger class intends to simply display log information, it can be defined as follows:
Ext. NS ('ext. UX. logger ');
There are
First, the problem arises.Project wrote a logger, originally is code, everyone can be used alone, but later project integration, everyone's part into the Lib, and the front end will be logger packaged together into LIB, the background according to reason should not include. cpp files can also be used in logger, Because if the background is also included and compi

When pomelo is used, it is found that log4js logs cannot be output to log files. The solution is as follows:1. Delete the./node_modules/pomelo-logger folder under the project directory.2. Modify the./node_modules/pomelo/package. JSON file under the project directory, find the pomelo-logger in dependencies, and delete the modified line.It is also found that the logs in pomelo-Admin cannot be output to the lo
