java.lang.IllegalArgumentException：屬性'dataSource'是必需的Spring JDBC

Question

我不知道我在做什麼錯誤，我試圖執行存儲過程使用jdbc調用，但是當我執行它的打擊異常 java。 lang.IllegalArgumentException：屬性'dataSource'是必需的。

控制器類：

@Controller 
    public class GpsController { 

     @RequestMapping(value="h",method=RequestMethod.POST)  
     public void show(@ModelAttribute("PredefinedPath") PredefinedPath predefinedPath) 

     { 

      PredefinedPathService service=new PredefinedPathService(); 
      //passing dto obj to service 
      boolean res= service.savePredefinedPath(predefinedPath); 
     } 

DTO CLASS：

//Entity Class Getters and setters

服務類：

      boolean result=predefinedPathDao.savePredefined(predefinedPathdto); 

      return result; 


     } 
    }

Answer 1

在控制器的服務爲你自己動手實例化不是由Spring管理。

這就是爲什麼數據源未在此bean中設置的原因。

替換：

@Controller 
public class GpsController { 

     @RequestMapping(value="h",method=RequestMethod.POST)  
     public void show(@ModelAttribute("PredefinedPath") PredefinedPath predefinedPath) 
     { 

      PredefinedPathService service=new PredefinedPathService(); 
      //passing dto obj to service 
      boolean res = service.savePredefinedPath(predefinedPath); 
     } 
} 

通過

@Controller 
public class GpsController { 
    @Autowired 
    private PredefinedPathService service; 

    @RequestMapping(value="h",method=RequestMethod.POST)  
    public void show(@ModelAttribute("PredefinedPath") PredefinedPath predefinedPath) 
     { 
      //passing dto obj to service 
      boolean res = service.savePredefinedPath(predefinedPath); 
     } 
}
