After the stored procedure is executed, it is read by the calling function.The processing of stored procedure parameters is the same as that of other SQL statements. Their names start with @, for example, @ departmentid. The simplest syntax for assigning values to output parameters in a stored procedure is as follows:Select @ resolve mentid = 5The following is

Previously, the process of uploading files was always a headache for developers, because the Servlet itself did not provide direct support, needed to be implemented using a third-party framework, and was not easy to use. Servlet 3.0 already provides this functionality and is very simple to use. To do this, HttpServletRequest provides two methods to parse the uploaded file from the request:? Part GetPart (String name) ? collectionpart> getparts ()The f

, Listener, etc.4. Added direct support for file uploads, Add the Getpart and GetParts method to Javax.servlet.http.HttpServletRequest, and add the Javax.servlet.http.Part interface, which should have provided this feature earlier, the unified file upload interface.5. The JSP file is packaged into a jar package as a resource file and deployed directly to the Web-inf/lib directory, which has many benefits for the product development project. The JSP fi

connects to the Web Service of the server. Therefore, during each startup, the dropdown list should be initialized in sequence, and each dropdown list will call the Web service once, while the Web Service is very slow. Slow startup speed. To speed up, I adjusted data connect to create a web service for all the dropdown lists and added the original results returned for each web service to the root of an XML file, you only need to call it once during the entire startup process. For example, I
