JAVA全栈第五天：服务层，控制层，基本测试

第五天

服务层/业务层

service

 //业务层/服务层--实现功能的业务逻辑
 ​
 @Service
 public class DepartmentService {
     
     @Autowired
     private DepartmentMapper mapper;
     
     public int insert(DepartmentModel model) {
         return mapper.insert(model);
     } 
     
     public int delete(DepartmentModel model) {
         return mapper.delete(model);
     }
     
     public int update(DepartmentModel model) {
         return mapper.update(model);
     }
     
     public DepartmentModel selectModel(DepartmentModel model){
         return mapper.selectModel(model);
     }
     
     public List<DepartmentModel> selectList(DepartmentModel model){
         return mapper.selectList(model);
     }
 }

 

 

控制层

controller

 //控制层
 //spring mvc
 //Model View Controller
 //servlet
 ​
 //访问：协议://主机地址:端口号/工程名/类上RequeatMapping/方法上RequestMapping？参数名1=值&参数名2=值
 ​
 @RestController
 @RequestMapping("department")//在不同的controller类上的RequestMapping中的内容不可以相同
 public class DepartmentController {
 ​
     @Autowired
     private DepartmentService service;
 ​
     @RequestMapping("test")
     public String test() {
         return "abc";
     }
     
     //
     @RequestMapping("insert")//在同一个controller类里面的不同方法上的RequestMapping的内容不可以相同
     public Map<String, Object> insert(DepartmentModel model) {
         Map<String,Object> map =new HashMap<>();
         map.put("code",service.insert(model));
         return map;
     }
     
     @RequestMapping("delete")
     public Map<String, Object> delete(DepartmentModel model) {
         Map<String,Object> map =new HashMap<>();
         map.put("code",service.delete(model));
         return map;
     }
     
     @RequestMapping("update")
     public Map<String, Object> update(DepartmentModel model) {
         Map<String,Object> map =new HashMap<>();
         map.put("code",service.update(model));
         return map;
     }
     
     @RequestMapping("selectModel")
     public Map<String, Object> selectModel(DepartmentModel model) {
         Map<String,Object> map =new HashMap<>();
         map.put("code",service.selectModel(model));
         return map;
     }
     
     @RequestMapping("selectList")
     public Map<String, Object> selectList(DepartmentModel model) {
         Map<String,Object> map =new HashMap<>();
         map.put("code",service.selectList(model));
         return map;
     }
 }

 

SpringBoot入口类配置

 @SpringBootApplication
 //@ConponentScan作用主要是为了扫描各个模块下的controller和service包
 @ComponentScan(basePackages= {"com.situ.demo.*.controller,com.situ.demo.*.service"})
 //@MapperScan作用主要是为了扫描各个模块下的mapper包
 @MapperScan(value="com.situ.demo.*.mapper")
 public class SituDemoApplication {
 ​
     public static void main(String[] args) {// main方法
         SpringApplication.run(SituDemoApplication.class, args);
     }
 ​
 }
