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

Question

我不确定我做错了什么，我正在尝试使用 jdbc 调用来执行存储过程，但是每当我执行它的命中异常时 java.lang.IllegalArgumentException: 属性 'dataSource' 是必需的。

控制器Class:

    @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);
        }

Answer 1

您控制器中的服务不受 Spring 管理，因为您自己实例化了它。

这就是为什么没有在此 bean 中设置数据源的原因。

替换：

@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);
        }
}

由

@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);
        }
}
