valid

java系列之-⾃定义valid校验器

⼀、依赖包

tion

validation-api

⼆、注解类

aints;

meRetrainsValidator;

aint;

d;

tType;

ion;

ionPolicy;

;

/**

*@Description:

*@Author:

*@CreateDate:

*@Version:1.0.0.1

*/

@SuppressWarnings("unud")

@Target()

@Retention(E)

@Constraint(validatedBy=)

public@interfaceRealNameRetrainsValid

{

Stringmessage()default"{e}";

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

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

}

三、校验处理类

tion;

nts;

lNameRetrainsVO;

meRetrainsValid;

Utils;

aintValidatorContextImpl;

aintViolationCreationContext;

aintValidator;

aintValidatorContext;

;

/**

*@Description:

*@Author:

*@CreateDate:

*@Version:1.0.0.1

*@Company:

*/

publicclassRealNameRetrainsValidatorimplementsConstraintValidator

{

@Override

publicvoidinitialize(RealNameRetrainsValidconstraintAnnotation){}

@Override

publicbooleanisValid(Stringvalue,ConstraintValidatorContextcontext)

{

ConstraintValidatorContextImplconstraintValidatorContext=(ConstraintValidatorContextImpl)context;

ListconstraintViolationCreationContexts=straintViolationCreationContexts();

ConstraintViolationCreationContextconstraintViolationCreationContext=(0);

ReqRealNameRetrainsVOreqRealNameRetrainsVO=(ReqRealNameRetrainsVO)h().getLeafNode().getParent().

if(_REAL_NAME_(eType()))

{

if(lank(value))

{

returntrue;

}

returnfal;

}

returntrue;

}

}

四、具体使⽤⽅法

1、⽅法⼊参加上@Valid注解

2、实体类字段加上

@RealNameRetrainsValid(message="")
