Spring boot示例。只做了一个查询功能，项目目录结构，使用eclipse建立的spring starter project项目。没做其他改动。

实体类，getter与setter使用的是lombok，有了lombok省的总写一堆浪费时间的getter setter toString 等等。

仓库

public interface ChineseDrugRepository extends Repository<ChineseDrugSpecification, Integer> {
    	ChineseDrugSpecification findById(Integer id);
    }

控制层

@Controller
    @RequestMapping("/")
    public class ChineseDrugController {
    	@Autowired
    	private ChineseDrugRepository readingListRepository;
    
    	@RequestMapping(value = "/{id}", method = RequestMethod.GET)
    	public String readersBooks(@PathVariable("id") Integer id, Model model) {
    		ChineseDrugSpecification chineseDrug = readingListRepository.findById(id);
    		if (chineseDrug != null) {
    			model.addAttribute("chineseDrug", chineseDrug);
    		}
    		return "readingList";
    	}
    }

页面。名称叫做readingList.html，页面技术采用的是thymeleaf

application.yml配置

spring:
      datasource: 
          username: root
          password: 123
          url: jdbc:mysql://192.168.1.6:3306/engine
          driver-class-name: com.mysql.jdbc.Driver

sql语句 ，注意您的mysql数据库字符集避免乱码。
