Due to the frequent use of powerdesigner in daily data modeling, the use of reverse engineering to generate models more quickly improves efficiency, so the summary is used as follows:1.

In the data modeling process, we establish a conceptual data model, generate a physical data model through a forward project, generate a database creation script, and finally generate a relational database from the physical data model. System database designe

One of the main features of MyBatis is the need for programmers to write their own SQL, so if the table is too much, it will be difficult, so MyBatis official provides a reverse engineering, can automatically generate MyBatis for a single table to execute the required code (including Map

Reverse engineering of MyBatis
One: What is retrograde engineering.
MyBatis is an excellent persistence layer framework that supports custom SQL, stored procedures, and advanced mapping. MyBatis avoids almost all JDBC code and manually sets parameters and gets the result set. MyBatis can use simple XML or annotations to configure and map native information, mappi

Mybaits requires programmers to write their own SQL statements,MyBatis The official reverse engineering can be automatically generated for a single table mybatis Execute the required code ( Mapper.java,mapper.xml , po.. ). in the enterprise actual development, the commonly used reverse engineering
MyBatis is a semi-automatic ORM, in the use of this framework, the biggest workload is to write mapping mapping file, because manual writing is very error-prone, we can use Mybatis-generator to help us automatically generate files.

When using PowerDesigner reverse engineering to generate PDM, column annotations (columncomment) are never generated, after several hours of exploration, find a compromise method, now share the following. And hope that there is a better way to guide the master.

The method is as follows:

Using PowerDesigner reverse engineering to guide the data Model diagram is very convenient, take Powerdesigner11 and Oracle8i as an example (other versions slightly different)
The basic steps are as follows:
