ArcGIS runtime SDK for iOS 2.2 is released at the developer summit. The enhancements in version 2.2 are as follows: 1. Search for and access content, users, and groups on arcgis.com; 2. Supports WMS layers; 3. Supports conversion between the Military Grid Reference System (MGRS) reference systems; 4. improved the performance of geometric operations when using agsgeometryengine; 5. Better Processing of "no data" tiles in the tile layer;

qualification is the opposite of subtype qualification, which can be supplied to a method, but the return value cannot be used. Super Manager This type is limited to all superclass of manager.pair? Super Manager GetFirst ()void Setfirst (? Super Manager)The compiler can invoke the Setfirst method with the manager's super type, such as Employee,object, but cannot invoke GetFirst because the manager's superclass reference cannot be converted to a manager reference.The existence of super-type qual

Most projects require only one transaction manager. However, some projects are best used with multiple transaction managers to improve efficiency, or to have multiple disparate and disparate data sources. Smart Spring's transactional management has taken this into account, first defining multiple transactional manager separately and assigning different values to the qualifier property Then specify the value of the TransactionManager qualifier property or use the bean name directly when you need

() { ... } @Transactional("datasource2Tx") public void doSomethingInDatasource2() { ... }} Alternatively, use the bean name of transpneumatic manager directly: @ Transactional ("transactionManager1 ") If @ Transactional () is used, the default transaction mananger name is used, that is, @ Transactional ("transactionManager ") Reference: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#tx-multiple-tx-mgrs-with-attransa

When we need to instruct the database to group rows and then limit the output of rows after the grouping, the correct method is to use the having statement: Select sales_clerk, Sun (sale_amount) from gross_sales where sales_dept = 'outlin
