If we want to start Tomcat, we can start the components one by one, but it has many disadvantages, which is not only troublesome, in addition, it is easy to miss the component startup, and it will also cause trouble for subsequent dynamic component expansion. Is it hard for us

// Attach the fragment to the current activity.
Public void onattach (activity ){
// Todo auto-generated method stubSuper. onattach (activity );}
Public void oncreate (bundle savedinstancestate ){// Todo auto-generated method stubSuper. oncreate (savedinstancestate );}

JspLife cycleThe key to understanding the underlying functionality of the JSP is to understand the life cycle that they follow.The JSP lifecycle is the entire process from creation to destruction, similar to the servlet life cycle, except that the JSP life cycle also includes compiling the JSP file into a servlet.Here are a few stages of the JSP life cycle:
Compile phase:servlet container compiles servlet source file, generates Servlet class
process is at least as high as the B process.3. Because the service process has a higher priority than the background process, it is better to open a service than to create a worker thread for an activity that requires a long-time operation, especially if the operation is likely to exceed the duration of the activity.For example, to upload an image file, you should open a service to upload the work, so that when the user leaves the activity is still working. Using the service will ensure that t
What is lifecycle:Maven's lifecycle is to abstract and unify all the building processes. Maven learns from and reflects on a large number of projects and build tools, and then summarizes a set of highly complete and scalable lifecycles. This lifecycle includes almost all of the building steps for the project, such as cleaning, initialization, compilation, testing, packaging, integration testing, verificatio

This article gives you an introduction to the lifecycle of activity, and if you've learned about iOS partners, the activity lifecycleis very similar to the lifecycle of Viewcontroller in iOS.

The life cycle of activity in Android is the process of creating and disappear
Maven has been used in the project for almost a year. Recently, it was suddenly found that the maven Project Build in eclipse is very slow, because the clean install command is often used to build the project, and there are not so many problems, however, I have been unable to cope with the same build speed as the tortoise recently. So I am determined to go over Maven practice,For me, Maven has two main roles: one is the dependency solution function for the jar package, and the other is to manage

BackgroundIn Android development, we are familiar with the Activity's Lifecycle and will perform specific operations under a specific Lifecycle. Of course, we know that Lifecycle itself is a feature of Android, that try to imagine, what if 普通的 Java Class 也能自动感知 Lifecycle 呢 ? It doesn't seem to make much sense to listen
while, We may need to update the version of this app, and finally, we may remove the app, because we don't need it anymore.We accomplish the "lifecycle management" process for applications by doing these operations externally or internally. For non-modular applications, these operations are the object of the entire application, and if it is for modular applications, then we can have a finer granularity (for a module in the application) to manage the
