springmvc注入service层详解编程语言

使用springmvc采用注解方式注入service：

1.在spring.xml配置文件中注入要扫描的类：

<context:component-scan base-package=”com.doron” >

<context:exclude-filter type=”annotation” expression=”org.springframework.stereotype.Controller”/>   

</context:component-scan>

2.service层

接口：

public interface TEventsService{  
   int insertSelective(HttpServletRequest req ,TItmpTcsEvents record); 
}

实现类：

@Service("eventsService") 
public class TEventsServiceImpl  implements TEventsService { 
    @Autowired 
    private TItmpTcsEventsMapper eventsMapper; 
    public int insertSelective(HttpServletRequest req ,TItmpTcsEvents record){ 
        return eventsMapper.insertSelective(record); 
    } 
}

3.controller层：

@Controller 
@RequestMapping(value = "/events") 
public class TEventsController{ 
    @Autowired 
    private TEventsService eventsService; 
    @SuppressWarnings("unused") 
    @RequestMapping(value = "/saveEvents", produces = {"application/json;charset=UTF-8"}) 
    @ResponseBody 
    public Map<String, Object> saveArtificalReceive(HttpServletRequest req, HttpServletResponse resp,TItmpTcsEvents record{ 
      Map<String, Object> result = new HashMap<String, Object>(); 
      int eventCount = 0; 
      eventCount = eventsService.insertSelective(req,record); 
      // 插入警情信息成功后返回前台 
      if (eventCount > 0){ 
          result.put("result", true); 
      }else { 
         result.put("result", false); 
      } 
   } 
}
