spring boot集成pagehelper(两种方式)

参看了pagehelper-spring-boot，使用起来非常放方便，关于更多PageHelper可以点击https://github.com/pagehelper/Mybatis-PageHelper。

当spring boot集成好mybatis时候需要进行分页，我们首先添加maven支持

< dependency >
 < groupId >com.github.pagehelper groupId >
 < artifactId >pagehelper artifactId >
 < version >5.1.2 version >
dependency >
< dependency >
 < groupId >com.github.pagehelper groupId >
 < artifactId >pagehelper-spring-boot-autoconfigure artifactId >
 < version >1.2.3 version >
dependency >
< dependency >
 < groupId >com.github.pagehelper groupId >
 < artifactId >pagehelper-spring-boot-starter artifactId >
 < version >1.2.3 version >
dependency >

方式一：我们在application.yml(spring 需要读取的yml)中加入

pagehelper:
 helperDialect: mysql
 reasonable: true
 supportMethodsArguments: true
 params: count=countSql

然后重启即可。

配置文件最终会被java所读取，最终注入到spring bean中，所以我们方法二是配置其bean类，热加载方便修改当然方式一更简单，

方式二：在注解涵盖package下面新建PageHeleperConfig

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

/**
 * @author zhuxiaomeng
 * @date 2018/1/2.
 * @email [email protected]
 */
@Configuration
public class PageHelperConfig {


 @Bean
 public PageHelper getPageHelper(){
 PageHelper pageHelper= new PageHelper();
 Properties properties= new Properties();
 properties.setProperty( "helperDialect" , "mysql" );
 properties.setProperty( "reasonable" , "true" );
 properties.setProperty( "supportMethodsArguments" , "true" );
 properties.setProperty( "params" , "count=countSql" );
 pageHelper.setProperties(properties);
 return pageHelper;
 }

}

pageHelper 基础知识为：

import com.github.pagehelper.Page;
import com.github.pagehelper.PageHelper;

Page tPage= PageHelper.startPage(page,limit);

下一句的查询语句来进行分页。你只需要用List接收
