Hibernate Validator introduced in non-web projects

Objective:

Some friends on the Internet shared the use of hibernate-validator, but not the information about the associated libraries, but the lack of custom classes in the reference code provided.

I hope this blog will allow you to smoothly run out of the expected results.

If there is any mistake, you can leave me a message.

Good friends in English can refer to the official website of getting started.

http://hibernate.org/validator/documentation/getting-started/

First, the environment

The Hibernate-validator library must be running with a JDK version of 1.6 and above.

Second, Hibernate-validator Library and dependence

1classmate-1.3.1. Jar2hibernate-validator-5.3.1. Final.jar3javax.el-2.2.4. Jar4javax.el-api-2.2.4. Jar5jboss-logging-3.3.0. Final.jar6validation-api-1.1.0. Final.jar

Third, suppose we construct a car class

1  Public classCar {2 3 @NotNull4     PrivateString manufacturer;5 6 @NotNull7@Size (min =2, max = -)8     PrivateString licenseplate;9 Ten@Min (2) One     Private intSeatcount; A  -      PublicCar (string manufacturer, String licenceplate,intSeatcount) { -          This. Manufacturer =manufacturer; the          This. licenseplate =licenceplate; -          This. Seatcount =Seatcount; -     } -  +      PublicString Getmanufacturer () { -         returnmanufacturer; +     } A  at      Public voidSetmanufacturer (String manufacturer) { -          This. Manufacturer =manufacturer; -     } -  -      PublicString getlicenseplate () { -         returnlicenseplate; in     } -  to      Public voidsetlicenseplate (String licenseplate) { +          This. licenseplate =licenseplate; -     } the  *      Public intGetseatcount () { $         returnSeatcount;Panax Notoginseng     } -  the      Public voidSetseatcount (intSeatcount) { +          This. Seatcount =Seatcount; A     } the  +}

Four, how to check it? Let's take a look at this test class

1  Public classCartest {2 3      Public Static voidMain (string[] args) {4Validatorfactory factory =validation.builddefaultvalidatorfactory ();5Validator Validator =factory.getvalidator ();6Car car =NewCar (NULL,"Sue A999999",1);7 8Set<constraintviolation<car>> constraintviolations =validator.validate (car);9          for(constraintviolation<car>constraintviolation:constraintviolations)TenSystem. out. println ("Error:"+constraintviolation.getmessage ()); One     } A}

V. What is the result?

1  ,  . Ten:afternoon org.hibernate.validator . internal. util. Version <clinit>25.3. 1 . Final3 error: cannot be null4 Error: Minimum cannot be less than 2

Six, really simple to use! Although the library repeatedly "invented" the wheel.

Seven, have you noticed? The result is an automatic internationalization!
