Spring study notes -- about the problem that Spring annotation scan cannot inject new objects Over the past few days, Leader has made me use the factory model to refactor some of the business logic code. The process is painful (I will not elaborate on it here) and the results are very sweet. Below is a record of a problem I encountered during the refactoring process.Some code is as follows: @ Service (orderFactory) public class OrderFactory implements

obtained the student instance in the static method and printed it out, and we also obtained the student instance through Springbeanutil in the new classroom instance, and output it. The output is as follows:trueI am a student.As you can see, both in the static method and in the instance of manual new, we have successfully acquired the beans managed by the IOC container. If we want to get Springbean in a static property, it's actually very simple, just assign a value to the property as follows:p

cause : When the bean is added to the project, @component cannot be scanned by spring (the idea will not be able to get the corresponding bean at compile time).Later, the research was related to the location of the document package.Springboot Bean Assembly Rules:Scan from top to bottom according to the package location where the application class is located!Scan the package of the application class and its child packagesNote: You can specify a scanned package by adding @componentscan (basepackag

Recently in the WebSocket chat, but encountered a problem, is in the WebSocket service to invoke the services layer of things. The first thing I think about is the injection of beans through @autowire annotations. But the test found that the injected bean was always null. Finally through the almighty Baidu to find out problems and solutions. Let's talk about my solutions:One, Contextloader.getcurrentwebapplicationcontext (BEANNAME.CLAAA)------> This scheme won't work.The real SolutionTwo1. First

of the classes it scans are automatically annotated and incorporated into the spring container, such as a class that[Java]View Plaincopy Public class Studentservice implements Istudentservice { } Then the tag is used to add @component annotations to the Studentservice class, and the Bean's ID is studentservice.[Java]View Plaincopy @Component ("Studentservice") Public class Studentservice implements Istudentservice { } Context:exclude-filterThe implicati

Among Apple's many Mac products, Mac Pro appears to be the easiest to ignore. This poor Mac Pro series was first introduced in 2006 to replace the Power Mac G5, but apparently Apple has now put it in the doghouse and has no faster processors like other MAC products, more efficient motherboard design and such as a lightning interface and USB 3.0. So, if you have a phased out Mac Pro, how can you inject new energy into it to achieve better usage? That's

When using intent to start a activity,service, the data can be transmitted through the Putextra, and the triggered Activity,service can use Getintent Getextras () Extra, The corresponding parameter values are then based on the extra key value (key). Roboguice provides a neat way to get these extra values through @injectextra tags. This example uses two Activity,injectextrademo to trigger the injectextrareceiver, and when intent is created in Injectextrademo, two parameters are placed Putextra

Inject service with annotation in static tool class, tool class service It is feasible to directly use the service in the Controller and encapsulate the service as a tool class before calling an error because the service cannot be loaded using the new method. The service loading process must be performed when the server is running. This is the problem I encountered at the time and the Final Solution conclusion: http://bbs.csdn.net/topics/392162820 Thi

Each process in windows has its own address space. They are independent of each other, ensuring system security. However, windows also designed some functions for the debugger or other tools that allow one process to operate on another process. Although they are designed for debuggers, any application can call them. Next we will talk about using remote threads to inject DLL. Basically, DLL injection is to inject
