springboot mybatis of pagehelper page

maven repositary, the paging component commonly used two

com.github.pagehelper » pagehelper-spring-boot-starter

com.github.pagehelper » pagehelper

Lay a lot of pits, a record of the way to be successful:

=============================== dividing line ================= =======

1. introduced in pom.xml Dependence: Selection 4.2.x version pagehelper of (5.1.2 If the election, I do not know how to configure, the Internet did not find)

<dependency>
       <groupId>com.github.pagehelper</groupId>
       <artifactId>pagehelper</artifactId>
       <version>4.2.1</version>
</dependency>

2. Configure class, which is 4.xx version of the wording, if it is 5.1.2, you can not write like below (no effect)

package com.yggdrasill.framework;

import com.github.pagehelper.PageHelper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.Properties;

@Configuration
public  class PageMybatisConf {
    @Bean
    public PageHelper pageHelper() {
        System.out.println("MyBatisConfiguration.pageHelper()");
        PageHelper pageHelper = new PageHelper();
        Properties p = new Properties();
        p.setProperty("offsetAsPageNum", "true");
        p.setProperty("rowBoundsWithCount", "true");
        p.setProperty("reasonable", "true");
        p.setProperty("dialect","postgresql");
        pageHelper.setProperties(p);
        return pageHelper;
    }
}

3. calling code

public PageInfo <the Slave> queryApiSlaveList (Pager <the Slave> Page) {
     // PageHelper.startPage (Page, the pageSize); plug open tab, on the top to help generate the query statement tab 
    PageHelper.startPage (page.getPage (), page. getPageSize ()); // 1,10 
    List <the Slave> listSlave = slaveMapper.selectAll ();
     // data after encapsulation tab back to the client to do show some PageInfo package as a class 
    PageInfo <the Slave> = pageInfoUser new new PageInfo <the Slave> (listSlave); 
    return pageInfoUser;
}

Results shown in Figure

carry out! ! !

===================================================================

ps: do not have to configure a few parameters in application.properties, and if it is into pagehelper-spring-boot-starter, you need to configure


pagehelper.helperDialect=postgresql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql
pagehelper.page-size-zero=true
