Spring Boot 表單驗證、AOP統一處理請求日志、單元測試

 一、使用@Valid表單驗證 

於實體類中添加@Min等注解

@Entity
public class Girl {

    @Id
    @GeneratedValue
    private Integer id;

    private String cupSize;
    @Min(value = 18,message = "未成年禁止入內!") 10     private Integer age;
...
}

 給指定的訪問方法參數添加@Valid 注解，並使用BindingResult bindingResult對象獲取返回結果

@PostMapping(value = "/girls")
    public Girl addgirl(@Valid Girl girl, BindingResult bindingResult){
        if (bindingResult.hasErrors()){
            System.out.println(bindingResult.getFieldError().getDefaultMessage());
            return null;
        }
        girl.setCupSize(girl.getCupSize());
        girl.setAge(girl.getAge());
        return girlRepository.save(girl);
    }

二、使用AOP處理請求

使用AOP統一處理請求日志

在pom文件中添加aop依賴，

<!-- aop依賴 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

新建aspect類：

@Aspect
@Component
public class HttpAspect {

    @Pointcut("execution(public * com.cenobitor.controller.GirlController.girlList(..))")
    public void log(){
    }

    @Before("log()")
    public void doBefore(){
        System.out.println(11111111);
    }

    @After("log()")
    public void doAfter(){
        System.out.println(22222222);
    }

}

/*
* 以日志的形式取代sout,顯示更詳細的信息
* */
@Aspect
@Component
public class HttpAspect {
    //import org.slf4j.Logger;
    private final static Logger LOGGER = LoggerFactory.getLogger(HttpAspect.class);
    //設置切點,簡化代碼
    @Pointcut("execution(public * com.cenobitor.controller.GirlController.girlList(..))")
    public void log(){
    }
    
    //獲取請求信息
    @Before("log()")
    public void doBefore(JoinPoint joinPoint){

        ServletRequestAttributes  attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        //URL
        LOGGER.info("url={}",request.getRequestURL());
        //IP
        LOGGER.info("ip={}",request.getRemoteAddr());
        //METHOD
        LOGGER.info("method={}",request.getMethod());
        //類方法
        LOGGER.info("class_method={}",joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName());
        //參數
        LOGGER.info("args={}",joinPoint.getArgs());

    }

    @After("log()")
    public void doAfter(){
        LOGGER.info("222222222222");
    }
    //打印返回結果
    @AfterReturning(returning = "object",pointcut = "log()")
    public void doAfterReturning(Object object){
        LOGGER.info("response={}",object.toString());
    }
}

三、單元測試

• 基本代碼：

@RestController
public class CustomerController {
    @Autowired
    private CustomerService customerService;

    @GetMapping(value = "customer_findById")
    public Customer findById(@RequestParam("id") Integer id){
        return customerService.findById(id);
    }
}vv

@Service
@Transactional
public class CustomerServiceImpl implements CustomerService {
    @Autowired
    private CustomerRepository customerRepository;

    @Override
    public Customer findById(Integer id) {
        return customerRepository.findOne(id);
    }
}

• service層測試

@RunWith(SpringRunner.class)
@SpringBootTest
public class CustomerServiceTest {
    @Autowired
    private CustomerService customerService;

    @Test
    public void findByIdTest(){
        Customer customer = customerService.findById(1);
        Assert.assertEquals("張三",customer.getName());

    }
}

• API測試（即controller層測試）：

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class CustomerControllerTest {
    @Autowired
    private MockMvc mvc;

    @Test
    public void findById() throws Exception {
        mvc.perform(MockMvcRequestBuilders.get("/customer_findById?id=1"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.content().string("abc"));//返回結果
    }
}

• 常用命令：
  • 執行打包並進行單元測試

mvn clean package

• • 執行打包並跳過所有單元測試

mvn clean package -Dmaven.test.skip=true
