spring boot集成pagehelper，兩種方式

當spring boot集成好mybatis時候須要進行分頁，咱們首先添加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：咱們在application.yml(spring 須要讀取的yml)中加入

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

而後重啓便可。

配置文件最終會被java所讀取，最終注入到spring bean中，因此咱們方法二是配置其bean類，熱加載方便修改固然方式一更簡單，

方式二：在註解涵蓋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 154040976@qq.com
 */
@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 基礎知識爲：

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

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

下一句的查詢語句來進行分頁。你只須要用List<T>接收
