Use PageHelper plug under MyBatis Environment

1, if the project is Maven build, it is very convenient, PageHelper first introduced package dependencies:

<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>4.1.6</version>
</dependency>

If not Maven project, it is necessary to introduce PageHelper jar package to the project.

2, MyBatis configuration file to configure:

< Plugins > 
<-! Com.github.pagehelper to PageHelper class where the package name -> 
< plugin Interceptor = "com.github.pagehelper.PageHelper" > 
<-! Set database type Oracle, Mysql, MariaDB, SQLite, Hsqldb, PostgreSQL database six kinds -> 
< Property name = "dialect" value = "MySQL" /> 
</ plugin > 
</ plugins >

 

3, using plug-ins:

// preceding code database query is performed by adding the following statement 
PageHelper.startPage (pageNum, the pageSize); 
List <Hospital> hospitalList = hospitalService.findList (Hospital);

 

4, configuration is complete, start the test.
