Question

我是Spring框架中的新手，需要测试一些后端软件。后端分为三层 - i）dao，ii）服务和iii）控制器。＆＃39; dao＆＃39;是最近的数据库层，所有SQL查询都在那里。＆＃39;服务＆＃39; layer用于制作来自＆＃39; dao＆＃39;的提取数据的JSON。层。控制器＆＃39; layer用于将JSON字符串抛出到前端。

架构是[数据库＆lt; - ＆gt; dao＆lt; - ＆gt;服务＆lt; - ＆gt;控制器＆lt; - ＆gt;前端]

三层的示例代码如下 - ＆gt;

GDao.java
==============

@Repository
public class GarageDao {

    private JdbcTemplate m_oJdbcTemplateObj;

    @Autowired
    public void setDataSource(DataSource dataSource) {
        this.m_oJdbcTemplateObj = new JdbcTemplate(dataSource);
    }

    /**
     * Query data base to get all the parking site id, identifier, description, and shape
     * @return list of map
     */

    public List<Map<String,Object>> getAllLocation() {
        List<Map<String, Object>> results; 
        try{
            // 
        } 
        catch(Exception e){
            // 
        }   
        return results;
    }
}

GServices.java
===================

@Service("m_oGarageService")
public class GarageServices {

    @Autowired
    private GarageDao m_oGarageDao;

    public String getAllLocation() {

        List< Map<String, Object> > results = m_oGarageDao.getAllLocation();

        try {

            if (null != results) {

                JSONObject featureCollection = new JSONObject();
                featureCollection .put("type", "FeatureCollection");


  JSONArray featureList = new JSONArray();

                        for (Map<String, Object> m : results) {
           // some code to insert data into featureList  
    }
                // return JSON data String 
                return featureCollection.toString();
            }      
        } 

        catch (JSONException e) {
            // some code
        }
        return null;
    }
}

GControllers.java
======================

@Controller
@RequestMapping("/garage")

public class GarageController {

    @Autowired
    private GarageServices m_oGarageService;


    @RequestMapping("/getall")

    public @ResponseBody ResponseEntity<String> getAllLocation(){
        HttpHeaders ResultHeader = new HttpHeaders();
        ResultHeader.set("Access-Control-Allow-Origin", "*");
        ResultHeader.set("Content-Type", "application/json");
        String result = m_oGarageService.getAllLocation();

        if(null ==  result){
            //  some code
         }
         return new ResponseEntity<String>(result, ResultHeader, HttpStatus.OK); 
     }
}

如何开始后端的写测试？感谢。

首先，我使用Spring Data存储库而不是自定义DAO代码。然后编写你的bean以使用构造函数注入，并使用与Mockito或Spock相同的方式使用模拟测试它们。
