The same-origin policy means that the protocol, host, and Port are the same. We can deploy 2 different ports of Tomcat on the local machine so that one Tomcat app accesses the rest service under another tomcat through Ajax, so there is a cross-domain access problem. Modify the three port numbers below the Conf/server.xml:On the basis of the previous blog, in order to solve the CXF cross-domain problem needs:1. Modify pom file to increase providers2. Modify the Cxf-spring.xml Configuration Jsonp

If we regard the organic composition of an application system as a human body, the hardware is the human brain and body, and the software is the human hand and foot; good hardware, in the end, appropriate software should be used to make full use of it. software is the most exposed to users. Good and bad software is crucial to users' operation experience and work efficiency!I have been engaged in the development of PLC software, MES system and communic

In the past two days, I have watched restful web services, especially the Jersey development environment under myeclipse, which provides information to display HTML requests and responses ,: In addition, you can submit data during post in myeclipse, but this tool is not available in Visual Studio. Today I found a blog: A blog of the China R D team of WCF tools. I mentioned that a tool webdevhelper () h

Mobile phone GPS positioning is slow, high precision, more power consumption, network positioning faster, low precision, less power consumptionWhen the position accuracy is very high, use GPS to locate, in general, use the network location.According to the first line of code to write a positioning program, the real machine has no location information output, but the simulator has output.Finally found the problem, the mobile phone positioning mode to the mobile network positioning, rather than GP

MyEclipse Support rest services, development is very convenient, I would like to give a computer example: implementation functions: Add, subtract, multiply, divide; The effect is as follows: Rest Service essentials: Each service or anything has a URI; Step 1: Create the Web Service Project; Step 2: Create Class Package org.xiazdong.service; Import Javax.ws.rs.GET; Import Javax.ws.r

The name changed, but the concept was the same. 。 Microsoft's impact on the Web services market, formerly code-named HailStorm, is now Microsoft. NET my Services. Of course, the name is a misnomer, because any soap-enabled platform can use Web services, and their use is not limited to. NET. And as always, it doesn't differ from the original SDK except for the sal

SceneUse react to do development and avoid using React-router React Router is already a V4 version. React RouterNow it has been divided into three packages: react-router , react-router-dom , react-router-native .The React Router application provides the core routing components and functions, while the other two packages provide the components of the specific environment (the browser and the react-native corresponding platform), but they

transmission channels (such as: Bluetooth, infrared, email, etc.) is quite convenient. Moreover, with the development of mobile phone hardware and software, the performance of mobile phone camera will be greatly improved, even in some respects, it can replace the traditional digital camera completely. Bluetooth is a wide range of short-range wireless technologies that, if mobile phones support Bluetooth, generally provide support in brew. 8 Software
