SpringBoot - PageHelper分页插件的配置

1. 导入依赖

     <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-starter</artifactId>
            <version>1.2.3</version>
        </dependency>

        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-autoconfigure</artifactId>
            <version>1.2.3</version>
        </dependency>

2. 全局配置 - application.yml

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

3. 使用

@RequestMapping(value = "", method = RequestMethod.GET)
@ResponseBody
public PageInfo<Product>  listUI( QueryParam queryParam) {


    // 分页设置，如果两个参数都为0则不分页 - 第一个页数为第N页、第二页为每页的记录数
    if(queryParam.getPageNum() == null) {
        PageHelper.startPage(0, 0);
    }else {
        PageHelper.startPage(queryParam.getPageNum(), queryParam.getPageSize());
    }
    
    // 这里sql文件不需要手动添加 limit
    List<Product> producets = productService.findAllProducts(queryParam);


    PageInfo<Product> pageInfo = new PageInfo<>(producets);

    return pageInfo;
}
