Spring Boot 表单验证、AOP统一处理请求日志、单元测试

一、使用@Valid表单验证

于实体类中添加@Min等注解

 @Entity
 public class Girl {

     @Id
     @GeneratedValue
     private Integer id;

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

给指定的访问方法参数添加@Valid 注解，并使用BindingResult bindingResult对象获取返回结果

 @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处理请求

使用AOP统一处理请求日志

在pom文件中添加aop依赖，

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

新建aspect类：

 @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,显示更详细的信息
 * */
 @Aspect
 @Component
 public class HttpAspect {
     //import org.slf4j.Logger;
     private final static Logger LOGGER = LoggerFactory.getLogger(HttpAspect.class);
     //设置切点,简化代码
     @Pointcut("execution(public * com.cenobitor.controller.GirlController.girlList(..))")
     public void log(){
     }

     //获取请求信息
     @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());
         //类方法
         LOGGER.info("class_method={}",joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName());
         //参数
         LOGGER.info("args={}",joinPoint.getArgs());

     }

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

三、单元测试

• 基本代码：

 @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层测试

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

     @Test
     public void findByIdTest(){
         Customer customer = customerService.findById(1);
         Assert.assertEquals("张三",customer.getName());

     }
 }

• API测试（即controller层测试）：

 @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"));//返回结果
     }
 }

• 常用命令：
  • 执行打包并进行单元测试

mvn clean package

• • 执行打包并跳过所有单元测试

mvn clean package -Dmaven.test.skip=true
