package com.bigdata.springboot_03030418.controller; import com.bigdata.springboot_03030418.pojo.User; import com.bigdata.springboot_03030418.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.domain.*; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import javax.persistence.EntityNotFoundException; import java.util.List; @RestController("/userController") //"/userController"为命名空间， //其作用为如果在不同控制器类中由相同的方法名（处理器），需要使用命名空间区分 public class UserController { //1、第一种直接使用接口方法 //2、在接口中自定义方法 @Autowired private UserService userService; //1、添加用户（单添加） @GetMapping("/addUser") public String addUser(){ //调用服务层 return userService.addUser(new User("03","爽歪歪",15)).toString(); } //2、查询（按非主键查询） @GetMapping("/findUserBySAge") public String findUserByUAge(Integer uAge){ List<User> userByUage = userService.findUserByUAge(uAge); if(userByUage.size()!=0){ return userService.toString(); }else { return "数据库中无年龄为"+uAge+"岁的人"; } } // 3、查询并排序（针对的是全查询） @GetMapping("/findUserAndSort") public String findUserAndSort(){ //给出排序规则,ascending()为升序,descending()为降序 Sort sort = Sort.by("uAge").ascending(); return userService.findUserAndSort(sort).toString(); } // 4、查询并分页（针对全查询） @GetMapping("/findUserAndPage") public String findUserAndPage(){ //给出分页规则,PageRequest类为PageAble接口的间接实现类，page表示的是起始页，size表示的是每页记录的数据条数 Pageable pageable = PageRequest.of(2,4); Page<User> userAndPage = userService.findUserAndPage(pageable); //获取总页数 int totalPages = userAndPage.getTotalPages(); //获取总记录条数 long totalElements = userAndPage.getTotalElements(); //获取当前页码 int number = userAndPage.getNumber(); //获取当前页面记录数 int size = userAndPage.getSize(); return "总页数:"+totalPages+",总记录条数:"+totalElements+",当前页码:"+number+",当前页面记录条数:"+size; } //5、查询排序并分页 @GetMapping("/findAllSortAndPage") public String findAllSortAndPage(){ //给出分页和排序规则，其中page为起始页，size为每页记录大小，Sort.by()方法给出排序规则 PageRequest sortAndPage = PageRequest.of(1, 2, Sort.by("uAge").descending()); //调用服务方法实现操作 Page<User> allSortAndPage = userService.findAllSortAndPage(sortAndPage); return "总共有"+allSortAndPage.getTotalPages()+"页"; } //6、使用Example封装数据实现查询操作 @GetMapping("/findAllByExample") public String findAllByExample(){ //将实例封装到Example中 User u = new User(); u.setUAge(18); //将实例对象封装到Example实例中 Example<User> example=Example.of(u); //调用服务层实现功能 List<User> allByExample = userService.findAllByExample(example); return allByExample.toString(); } //(1)使用Example封装数据实现查询操作并排序（参照任务3） @GetMapping("/findAllByExampleAndSort") public String findAllByExampleAndSort(){ User u = new User(); Example<User> example = Example.of(u); Sort sort = Sort.by("uAge").ascending(); return userService.findAllByExampleAndSort(sort).toString(); } //(2)使用Example封装数据实现查询操作并分页（参照任务4） @GetMapping("/findAllByExampleAndPage") public String findAllByExampleAndPage(){ User u = new User(); u.setUAge(18); Pageable pageable = PageRequest.of(2,4); Page<User> allByExampleAndPage = userService.findAllByExampleAndPage(pageable); int totalPages = allByExampleAndPage.getTotalPages(); long totalElements = allByExampleAndPage.getTotalElements(); int number = allByExampleAndPage.getNumber(); int size = allByExampleAndPage.getSize(); return "总页数:"+totalPages+",总记录条数:"+totalElements+",当前页码:"+number+",当前页面记录条数:"+size; } //7、更新操作（通过姓名改变年龄） // URL:localhost:8080/updateUAgeByUName?uName=韩梅梅&uAge=18 @GetMapping("/updateUAgeByUName") public String updateUAgeByUName(String uName,Integer uAge){ Integer updateNum = userService.updateUAgeByUName(uName, uAge); return "共更新了"+updateNum+"条"; } //8、使用getOne()实现查询操作，其作用与findById类似，即为条件查询，但在结果处理上有区别 //getOne()方法如果没有查询到记录，则会报EntityNotFoundException，但findById()如果没有查询到记录 //则会返回null值，因此针对使用getOne()方法进行条件查询的情况，需要对EntityNotFoundException异常进行处理 @GetMapping("/getOneUser") public String getOneUser(String uid){ //调用服务层 try{ //该处为可能出现异常的代码块，如果出现异常则执行catch(异常类型){}代码块，如果未出现异常，则执行try(){}代码块 User oneUser = userService.getOneUser(uid); return oneUser.toString(); }catch (EntityNotFoundException e){ return "查无此人"+e.getMessage(); } } }
