Effect Demand analysis of design ideasImage browsing, up/down, zoom out and other basic functions. Features you can continue to expand: thumbnails, rotations, brush changes, and more. In addition, the scaling implementation is relatively simple, so there is distortion. Design such software functions can refer to ACDSee or IrfanView and other viewing software.Knowledge points1. File filtering, File io:filefilter2. File dialog box:jfilechooser(add File Filtering function)3.
Today, when using the KVM Management room machine, I found a connection, reported the following error:Sun.security.validator.ValidatorException:PKIX Path validation failed: java.security.cert.CertPathValidatorException:Algorithm constraints Check Failed:md5withrsa650) this.width=650; "title=" Kv.png "alt=" Wkiom1cp8ucxxiebaag4bnb_kc8082.png "src=" http://s3.51cto.com/wyfs02/M00/ 7f/b7/wkiom1cp8ucxxiebaag4bnb_kc8082.png "/>I'm sure I've added the domain name to the exception, but it's still not w

Today, when making a Java Web project, the Chinese characters in HTML are displayed as garbled in the browser, and the possible reasons for this analysis are:(1) There is a default encoding in the HTML file attribute, and if its settings conflict with the content CharSet property setting in the HTML document, it is displayed as garbled.(2) related to the browser,
Sometimes, because Nginx and F5 policy problem need to add a prefix in the access to the system to distinguish between the need to use the same project;For example: When accessing localhost:8080/webdemo/demo/shafei.jsp, another way of access is required: localhost:8080/sf/webdemo/demo/shafei.jsp;The use of SF logo to distinguish different places need to access the system;How to do it:This needs to be configured in Tomcat's server.xml to change the project:Locate the context path="Sf/webdemo" doc

There are two ways to get Baidu data, one is to use the URL to get from the stream, the other is to open the browser directly. Text recognition (OCR) and then transcoding can be fast Baidu Public Static voidMain (string[] args)throwsIOException {//URL link AddressString localpath = "http://www.baidu.com/s?tn=ichunerlm=-1word=" +Urlencoder.encode ("Jiangsu provincial capital", "gb2312") + "rn=1"; URL URL=NewURL (LocalPath); //get the returned data
In general, it is unavoidable to encounter the call of external interface in project development, this article illustrates the method of Java background call HttpURLConnection class to simulate browser request. Can be used for interface calls. Share to everyone for your reference. The implementation methods are as follows:
