SpringBoot集成分页插件PageHelper

在 pom.xml 中单独添加如下依赖：

<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>4.1.3</version>
</dependency>

然后配置PageHelper插件相关属性

//分页插件,插件无非是设置mybatis的拦截器
PageHelper pageHelper = new PageHelper();
Properties properties = new Properties();
properties.setProperty("reasonable", "true");
properties.setProperty("supportMethodsArguments", "true");
properties.setProperty("returnPageInfo", "check");
properties.setProperty("params", "count=countSql");
pageHelper.setProperties(properties);

//添加插件
bean.setPlugins(new Interceptor[]{pageHelper});

这个是在java代码里配的

因为当前工程是用SpringBoot搭的，可直接集成

<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>tk.mybatis</groupId>
<artifactId>mapper-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>

配置信息可写在application.properties配置文件里

pagehelper.dialect=com.github.pagehelper.dialect.helper.MySqlDialect
pagehelper.row-bounds-with-count=true
pagehelper.reasonable=true
pagehelper.support-methods-arguments=true
pagehelper.params=count=countSql

调用方式

public PageInfo queryAffairs(int pageNum, int pageSize) {
PageHelper.startPage(pageNum,pageSize);
List<Affair> list=affairMapper.queryAffairs();
PageInfo<Affair> page=new PageInfo(list);
return page;
}

PageInfo本身封装了很多的分页信息:
