kibana data sources

Project needs to get data from other sites, because it is a temporary addition to the requirements, at the beginning of the project did not expect to need multiple data sources So Baidu a bit, found that only need to change the spring applicationcontext.xml files and write three tool classes can be a perfect implementation Applicationcontext.xml Dataso

Sometimes you need to connect to multiple databases, data sources are inconsistent and need to be configured.1, configuration XML. A data source, a template.......Multiple configurations can be repeated.The corresponding class is inherited Basicdatasource. and encryption operations are possible.2, public class.@Autowiredprotected JdbcTemplate JdbcTemplate;@Autowi

spring2.0 later added abstractroutingdatasource this thing provides a dynamic switching data source. Abstractroutingdatasource inherits the Abstractdatasource,abstractdatasource is a subclass of Javax.sql.DataSource. Here is an example of a dynamically switching data source: 1. configuration file configuration in Spring.xml 2. Creating an implementation class for dynamically switching

service, injecting the Servie into the controller, interacting with the server In actual projects, the service also needs to interact with the server. var app = Angular.module ("App", []); App.service ("Todoservice", Function ($q, $timeout) { This.gettodos = function () { var d = $q. Defer (); Simulates a request $timeout (function () { d.resolve ([ {item: ", Done:false}, ... ]) },3000); return d.promise; } This.addtodo = function (item) { This.todos.push ({item:item, done:false}); } )

JBoss is a very powerful Java EE application Server, but this powerful feature also brings complexity. The author of this article, Marcus Zarra, analyzes how to configure multiple databases and data sources in JBoss. Configure a data source The default setup process for JBoss is a total of three configuration options: all, default, and minimum (minimal). If you

not pass the connection is discarded and a connection is reassigned. The default is FalseNBSP; N test-after-use If set to True connection will be tested with the House-keeping-test-sql set before closing (putting back the connection pool) if the test does not pass connection will be discarded. The default value is FalseNBSP; ? Unlike other connection pooling features, Proxool does not provide a set method. All features have to be info.setproperty ("Proxool.jmx", "false"), NBSP; ?

Jndi The default address for the Wildfly service Management console is Http://127.0.0.1:9990/console, and after linking because there are no users, you will be prompted to add users through Add-user.bat. Just follow the prompts to create the user and then log in to the console with the user you created. There is a problem here, when creating the data source, you need to select the JDBC driver deployed in the system, then you need to put the driver ja

The following are the steps for a specific configuration:1. First configure the Jndi data source under Tomcat. The specific storage directory Apache-tomcat-7.0.59\conf\catalina\localhostOsh.xml(2) The database driver jar is placed in the Lib directory in the Tomcat installation file.(3) Spring Applicationcontext.xml is configured in DataSource:Note that java:comp/env must be added to the Vlaue attribute, followed by the name of resource in servers(4)
