The method of using PageHelper for pagination in Java is as follows:<\/p>\n

    \n
  1. First of all, to introduce PageHelper dependency into your project, you can add the dependency through Maven or Gradle.<\/li>\n<\/ol>\n
    <dependency<\/span>><\/span>\r\n    <groupId<\/span>><\/span>com.github.pagehelper<\/groupId<\/span>><\/span>\r\n    <artifactId<\/span>><\/span>pagehelper<\/artifactId<\/span>><\/span>\r\n    <version<\/span>><\/span>5.2.1<\/version<\/span>><\/span>\r\n<\/dependency<\/span>><\/span>\r\n<\/code><\/pre>\n
      \n
    1. Add PageHelper methods to your Mapper interface to set pagination parameters.<\/li>\n<\/ol>\n
      import<\/span> com.github.pagehelper.Page;\r\n\r\npublic<\/span> interface<\/span> YourMapper<\/span> {\r\n    List<YourEntity> selectByPage<\/span>(Page<YourEntity> page)<\/span>;\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Write the corresponding SQL statements in your Mapper interface’s XML file.<\/li>\n<\/ol>\n
        <select<\/span> id<\/span>=\"selectByPage\"<\/span> resultType<\/span>=\"YourEntity\"<\/span>><\/span>\r\n    SELECT * FROM your_table\r\n<\/select<\/span>><\/span>\r\n<\/code><\/pre>\n
          \n
        1. Call the methods of PageHelper in your Service layer to perform pagination queries.<\/li>\n<\/ol>\n
          import<\/span> com.github.pagehelper.Page;\r\nimport<\/span> com.github.pagehelper.PageHelper;\r\n\r\npublic<\/span> class<\/span> YourService<\/span> {\r\n    @Autowired<\/span>\r\n    private<\/span> YourMapper yourMapper;\r\n\r\n    public<\/span> List<YourEntity> selectByPage<\/span>(int<\/span> pageNum, int<\/span> pageSize)<\/span> {\r\n        Page<YourEntity> page = PageHelper.startPage(pageNum, pageSize);\r\n        yourMapper.selectByPage(page);\r\n        return<\/span> page.getResult();\r\n    }\r\n}\r\n<\/code><\/pre>\n
            \n
          1. Finally, in your Controller layer, call the method from the Service layer to retrieve paginated data.<\/li>\n<\/ol>\n
            import<\/span> org.springframework.beans.factory.annotation.Autowired;\r\nimport<\/span> org.springframework.web.bind.annotation.GetMapping;\r\nimport<\/span> org.springframework.web.bind.annotation.RequestParam;\r\nimport<\/span> org.springframework.web.bind.annotation.RestController;\r\n\r\n@RestController<\/span>\r\npublic<\/span> class<\/span> YourController<\/span> {\r\n    @Autowired<\/span>\r\n    private<\/span> YourService yourService;\r\n\r\n    @GetMapping(\"\/yourData\")<\/span>\r\n    public<\/span> List<YourEntity> getYourData<\/span>(@RequestParam<\/span> int<\/span> pageNum, @RequestParam<\/span> int<\/span> pageSize)<\/span> {\r\n        return<\/span> yourService.selectByPage(pageNum, pageSize);\r\n    }\r\n}\r\n<\/code><\/pre>\n
            Following these steps, you can now use PageHelper for pagination in Java. Hope it helps you!<\/p>\n","protected":false},"excerpt":{"rendered":"
