Today in the project encountered a very strange problem, the use of oclazyload lazy load angular module, refresh the page, click the rollback button can not return to the previous page. It is estimated that the lazy loading mechanism destroys the State association within the angula
With the oclazyload you can load AngularJS modules on demand. This was very handy for runtime loading of Angular modules in large applications.' Use strict ';//Declare app level module which depends on filters, and servicesvarApp = Angular.module (' app ', [' ui.router ', ' oc.lazyload ']). config (function($stateProvider, $locationProvider, $urlRouterProvider, $ocLazyLoadProvider) {$urlRouterProvider. othe
,proxy, the default is lazy= "proxy".The specifics of what to look for depends on your needs, not which settings are the best.If you include a Head object in a student objectIf you are sure that you want to use the student object with the properties of the head object, then you set the load immediately, because the settings are loaded immediately then query student at the same time will query student head, Hibernate will correlate two tables at query
Level 1 cache, level 2 cache, and lazy loading (transfer) in Hibernate, and level 1 cache in hibernate1. Why cache?
Hibernate uses cache to reduce the number of accesses to the database, thus improving the execution efficiency of hibernate. There are two types of cache in hibernate: level-1 cache and level-2 cache.
module.js first defines a type (function) Module. This type has two functions. One, which is the base class for all modules, after which each module is an instance of this module. This is also the ultimate source of our previous discussion module.exports .The second function of this module is to complete the loading process of the node module. The require() last thing we use is to call the Module.require method, and this method calls another internal

object to objectcontext requires multiple round-trips to the database and multiple active result sets. However, the returned data volume is limited to the loaded object. You can use the load method for entitycollection or entityreference or the loadproperty Method for objectcontext to explicitly retrieve relevant entities from the data source. Each call to the load method opens a connection to the database to retrieve relevant information. This ensures that the query is never executed when no e

Recently in the work of exposure to angular modular packaging loaded some of the content, feeling the middle of a few holes, marking this.
Project background:
The project mainly uses the ANGULARJS as the front-end frame, when the project is released, all the front-end scripts are packaged into a file, loaded at the time of the first visit of the page, causing the page to start loading
table data in the buffer.References:The delayed loading mechanism is proposed to avoid unnecessary performance overhead. The so-called delayed loading means that data loading is performed only when data is actually needed. Hibernate provides delayed loading of object objects and delayed
called in the main function.But this can cause a mistake:This is a lazy load exception: When the Session object is opened, we delay loading an object, and then we close the session. This exception is reported when you want to use this object in the main function.Here are a few solutions:1. Replace with Get (Class,id) methodWith the Get (Class,id) method, we will generate an SQL statement when the getuser (

In development, if an instance is created that consumes a lot of system resources, we typically use lazy loading mechanisms, which means that this instance is created only when this instance is used, which is widely used in singleton mode. The implementation of this mechanism in single-threaded environment is very simple, but there are hidden dangers in the multi-threaded environment. This article focuses o
