Question

yeah, the same question as @PathVariable Validation in Spring 4 and Add class level validation to @Pathvariable in Spring

spring validated not work for param, throw no exception, here is my code follow by @Patrick's answer, thx for him

@Bean
public MethodValidationPostProcessor methodValidationPostProcessor() {
     return new MethodValidationPostProcessor();
}

/**
 * 
 * @param accountId
 */
@RequestMapping(value="/orderDetailSelByAccountId/{accountId}.json",method= {RequestMethod.POST})
@ResponseBody
@Validated
public Result<?> orderDetailSelByAccountId(  @NotNull @NotBlank 
@Size(min=10,max=32)@PathVariable(value="accountId") String accountId) { ....    }
