学习知识点

1、Spring Security

2、@Aspect

3、logstash

4、 es

crud

templete

5、@Validated

ConstraintValidator 

BindingResult

1、定义注解
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD,ElementType.PARAMETER})
@Constraint(validatedBy = FlagValidatorClass.class)
public @interface FlagValidator {
    String[] value() default {};

    String message() default "flag is not found";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

2、定义校验器
public class FlagValidatorClass implements ConstraintValidator<FlagValidator,Integer> {
    private String[] values;
    @Override
    public void initialize(FlagValidator flagValidator) {
        this.values = flagValidator.value();
    }

    @Override
    public boolean isValid(Integer value, ConstraintValidatorContext constraintValidatorContext) {
        boolean isValid = false;
        if(value==null){
            //当状态为空时使用默认值
            return true;
        }
        for(int i=0;i<values.length;i++){
            if(values[i].equals(String.valueOf(value))){
                isValid = true;
                break;
            }
        }
        return isValid;
    }
}

3、model定义
@FlagValidator(value = {"0","1"},message = "状态只能为0或1")
private Integer showStatus;

4、控制器controller

@ApiOperation("创建商品")
@RequestMapping(value = "/create", method = RequestMethod.POST)
@ResponseBody
public Object create(@RequestBody PmsProductParam productParam, BindingResult bindingResult) {
    int count = productService.create(productParam);
    if (count > 0) {
        return new CommonResult().success(count);
    } else {
        return new CommonResult().failed();
    }
}

5、错误处理
@Aspect
@Component
@Order(2)
public class BindingResultAspect {
    @Pointcut("execution(public * com.macro.mall.controller.*.*(..))")
    public void BindingResult() {
    }

    @Around("BindingResult()")
    public Object doAround(ProceedingJoinPoint joinPoint) throws Throwable {
        Object[] args = joinPoint.getArgs();
        for (Object arg : args) {
            if (arg instanceof BindingResult) {
                BindingResult result = (BindingResult) arg;
                if (result.hasErrors()) {
                    return new CommonResult().validateFailed(result);
                }
            }
        }
        return joinPoint.proceed();
    }
}

6、Swagger

@Configuration
@EnableSwagger2

@ConditionalOnExpression("'${swagger.enable}' == 'true'")

public class Swagger2Config { @Bean public Docket createRestApi(){ return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.macro.mall.search.controller")) .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("mall搜索系统") .description("mall搜索模块") .contact("macro") .version("1.0") .build(); } }

7、线程池初始化

@Configuration
public class ThreadConfig {

    @Value("${concurrent.core.size}")
    private int coreSize ;

    @Value("${concurrent.max.size}")
    private int maxSize ;

    @Value("${concurrent.blockqueue.size}")
    private int blockQueueSize;

    @Bean(value = "concurrentTestThread")
    public ExecutorService build(){
        ThreadFactory namedThreadFactory = new ThreadFactoryBuilder()
                .setNameFormat("concurrent-thread-%d").build();
        ThreadPoolExecutor executorServicePool = new ThreadPoolExecutor(coreSize, maxSize, 0L, TimeUnit.MILLISECONDS,
                new ArrayBlockingQueue<Runnable>(blockQueueSize), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());

        return executorServicePool ;
    }

}

@Resource(name = "concurrentTestThread")
private ExecutorService executorService;
