talend data integration

recently, we have developed a small system that requires data integration with the original system. At first, I wanted to directly access the database, but later I felt that this method was too coupled, So I abandoned it. After testing, we feel that using WebService to capture data from the parent system in real time, generate XML

The no match output of lookup transformation directly copies the lookup transformation's input. If no match is found, the data will be directly transmitted to the next data stream. After all the operations are completed,

[Spring Data MongoDB] learning notes-awesome MongoTemplate and mongodb integration with spring The operation template is an interface between the database and the Code. All operations on the database are in it. Note: Producer template is thread-safe. Using template implements interface operations. It is generally recommended to use operations for related operations.

connected with the inventory system. In an intuitive sense, you can transmit the procurement order information to the inventory system as a reference for warehouse receiving, and you can control the number of warehouse receiving orders without unnecessary orders. Because the original inventory system has achieved data interconnection with the financial system, there is no need for the procurement system to directly exchange

=1 , we'll see article and blog two different objects.In TestController , we get a list of all repository through dependency injection. When the user accesses /test , the system will find the type corresponding repository according to the traversal of all repository, and then call the method to find the findOne(id) corresponding object. So we don't need one. To get repository instances, this is a more efficient way to manage objects when the domain objects become more and more powerful.@RestCont
