Preface: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->It is said that the recording is less time-consuming. However, it took a lot of effort to finally get this B out. The following description is almost the same as in the previous section: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->This recording is mainly for use: CYQ.

For the following JSON data:Encapsulate using the following bean:public class Newbean {public Newbeanitem data;public string Retcode;public class Newbeanitem{public string Countcommentur l;//Loading public string More;public string title;public listThat is: Data is a bean, and [] represents a list collectionNOTE: null for JSON data returned by the server, the gen

Because the project uses the data in the JSON format, search on the internet to Ali's Fastjson more useful, hereby record Fastjson usage, for later query.DecodeFirst create a JSON parsing class: Public class jsonparser { privateint devid; Public int Getdevid () { return devid; } Public void setdevid (int devid) { this. devid = devid; }} Create a corresponding object where parsing is needed:String str = "{" Devid ": 1

On the itpub saw someone raise this question, can use the data pump to export a query result. In fact, the data pump really has this function. Establish a simple test environment: sql> CREATE TABLE T1 2 (ID number, NAME VARCHAR2 (30)); Table created. Sql> INSERT into T1 2 SELECT rownum, Tname 3 from TAB; Created rows. sql> CREATE TABLE T2 2 (ID number,

Recently, a large number of EXCEL tables are required for the project. We plan to make all the data into an Excel table and import the data from the Excel table to the database through the editor. The editor provides various editing operations, you can also export a database to an Excel table. With the help of Java Excel API, this problem is very simple.I. The simplest method in history For simple tables (p

ManyProgramUse an XML file as the storage carrier for configuration data. You can use zend_config_xml to easily read data from the xml configuration file. The format is as follows:Zend_config_xml (filename, section, allowmodifications) The first parameter is the XML file name, and the second parameter is the node name. Third, I don't need to explain it. The fol

, we define a data source named Mysqlds, whose parameters include the JDBC URL, driver class name, username and password, and so on. 2, in the program to refer to the data source: Connection Conn=null; Try {context ctx=new initialcontext ();Object datasourceref=ctx.lookup ("Java:mysqlds"); Reference data source DataSource ds= (DataSource) datasourceref; Conn=d

People always like to add custom attributes to HTML tags to store and operate on data. However, you do not know whether other scripts will reset your custom attributes in the future. In addition, if you do this, the html syntax does not conform to the Html specification, and some other side effects are also caused. This is why a custom data attribute is added to the HTML5 specification, and you can
