Validation校验属性格式

基于javax.validation.Validation校验属性格式

一、maven依赖

<dependency>    <groupId>javax.validation</groupId>    <artifactId>validation-api</artifactId>    <version>1.0.0.GA</version></dependency><dependency>    <groupId>org.hibernate</groupId>    <artifactId>hibernate-validator</artifactId>    <version>4.3.1.Final</version></dependency>

二、代码示列

package validation;import javax.validation.constraints.NotNull;import javax.validation.constraints.Size;public class Address {    @NotNull    @Size(max = 30)    private String addressline1;    @Size(max = 30)    private String addressline2;    private String zipCode;    private String city;    public String getAddressline1() {        return addressline1;    }    public void setAddressline1(String addressline1) {        this.addressline1 = addressline1;    }    public String getAddressline2() {        return addressline2;    }    public void setAddressline2(String addressline2) {        this.addressline2 = addressline2;    }    public String getZipCode() {        return zipCode;    }    public void setZipCode(String zipCode) {        this.zipCode = zipCode;    }    @Size(max = 30)    @NotNull    public String getCity() {        return city;    }    public void setCity(String city) {        this.city = city;    }}

package validation;import javax.validation.ConstraintViolation;import javax.validation.Validation;import javax.validation.Validator;import javax.validation.ValidatorFactory;import java.util.Set;/** * Created by zhengyong on 17/1/17. */public class ValidationTest {    public static void main(String[] args) {        Address address = new Address();        address.setAddressline1(null);        address.setAddressline2(null);        address.setCity("Llanfairpwllgwyngyllgogerychwyrndrobwyll-llantysiliogogogoch");        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();        Validator validator = factory.getValidator();        Set<ConstraintViolation<Address>> constraintViolations = validator.validate(address);        for (ConstraintViolation<Address> constraintViolation : constraintViolations) {            System.out.println(constraintViolation.getPropertyPath() + ":" + constraintViolation.getMessage());        }    }}

三、运行结果

city:个数必须在0和30之间addressline1:不能为null

四、注意事项

异常：

Caused by: java.lang.NoClassDefFoundError: javax/validation/ParameterNameProvider    at org.hibernate.validator.HibernateValidator.createGenericConfiguration(HibernateValidator.java:41)    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:269)    at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:111)    at org.hibernate.cfg.beanvalidation.TypeSafeActivator.getValidatorFactory(TypeSafeActivator.java:445)    at org.hibernate.cfg.beanvalidation.TypeSafeActivator.activate(TypeSafeActivator.java:96)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)    at java.lang.reflect.Method.invoke(Unknown Source)    at org.hibernate.cfg.beanvalidation.BeanValidationIntegrator.integrate(BeanValidationIntegrator.java:150)    ... 50 more
