SpringBoot集成分页插件PageHelper

在 pom.xml 中单独添加如下依赖：

        <dependency>
            <groupId>com.github.pagehelpergroupId>
            <artifactId>pagehelperartifactId>
            <version>4.1.3version>
        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.bootgroupId>
            <artifactId>mybatis-spring-boot-starterartifactId>
            <version>1.1.1version>
        dependency>
        <dependency>
            <groupId>tk.mybatisgroupId>
            <artifactId>mapper-spring-boot-starterartifactId>
            <version>1.1.1version>
        dependency>
        <dependency>
            <groupId>com.github.pagehelpergroupId>
            <artifactId>pagehelper-spring-boot-starterartifactId>
            <version>1.1.1version>
        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 list=affairMapper.queryAffairs();
        PageInfo page=new PageInfo(list);
        return page;
    }

PageInfo本身封装了很多的分页信息:
