编写application.yml配置文件

 

spring:
  datasource:
    driverClassName: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/springboot
    username: root
    password: root
  jpa:
    database: MySQL
    show-sql: true
    generate-ddl: true
page:
  rows: 50

 

编写Controller，将结果传给模板

 

@Controller
public class PageController {
    @Autowired
    private UserDao userDao;
    @Value("${page.rows}")
    private Integer rows;
    @RequestMapping("/page/user/list")
    public String showUserList(Model model){
        List<User> userList=userDao.findAll();
        model.addAttribute("userList",userList);
        return "user";
    }
    @RequestMapping("/page/rows")
    @ResponseBody
    public Map showRows(){
        Map map = new HashMap();
        map.put("rows",rows);
        return map;
    }
}
