springboot使用PageHelper

官方文档：如何使用分页插件

1、引入插件

<!--        分页插件-->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>5.3.2</version>
        </dependency>

2、注册配置文件

 //mybatis的分页插件组件
    @Bean
    public PageInterceptor pageInterceptor(){
        PageInterceptor pageInterceptor = new PageInterceptor();
        Properties properties=new Properties();
        properties.setProperty("helperDialect","mysql");
        properties.setProperty("reasonable","true");
        properties.setProperty("rowBoundsWithCount","true");
        pageInterceptor.setProperties(properties);
        return pageInterceptor;
    }

3、使用

 @Override
    public PageInfo<Student> queryLike(int pageNum, int pageSize,Student student) {
        PageHelper.startPage(pageNum,pageSize);
        List<Student> students = studentMapper.queryLike(student);
        return new PageInfo<Student>(students);
    }

@RequestMapping (value = "/queryLike",method = RequestMethod.POST)
    @ResponseBody
    public String queryLikeStudents(int pageSize,int pageNum, String stuNumber, String stuName, String clazz
    ){
        Student student = new Student();
        student.setClazz(clazz);
        student.setStuName(stuName);
        student.setStuNumber(stuNumber);

        PageInfo<Student> studentPageInfo = ssi.queryLike(pageNum, pageSize, student);
        logger.info("queryLike--studentPageInfo = " + JSON.toJSONStringWithDateFormat(studentPageInfo,"yy-MM-dd"));
        return JSON.toJSONStringWithDateFormat(studentPageInfo,"yyyy-MM-dd");
    }
