How can to set validation (org.hibernate.validator.constraints) for rest in spring boot project? -

i have project spring boot, spring mvc , hibarnate, , want validate rest params, have controller:

import domain.user; import service.userservice; import validate.email; import org.apache.log4j.logger; import org.hibernate.validator.constraints.notempty; import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.controller; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.requestmethod; import org.springframework.web.bind.annotation.responsebody;  import javax.ws.rs.formparam; import java.util.arraylist; import java.util.list;  @controller public class usercontroller {      @autowired     private userservice userservice;      @requestmapping(value = "/registration", method = requestmethod.post)     public @responsebody boolean registration(@notempty @formparam("login") string login,                                 @notempty @formparam("password") string password,                                 @email(canbenullorempty = true) @formparam("email") string email) {         logger.debug("method registration params login = " + login                 + ", password = " + password + ", email = " + email);         return !userservice.findbyloginandpassword(login, password)                 && userservice.adduser(new user(login, password, email));     }  } 

and build.gradle:

apply plugin: 'war' apply plugin: 'spring-boot'  buildscript {     repositories {         mavencentral()     }     dependencies {         classpath("org.springframework.boot:spring-boot-gradle-plugin:1.1.8.release")     } }  ext {     springversion = '4.1.5.release'     jacksonversion = '2.5.3' }  sourcecompatibility = 1.5  repositories {     mavencentral() }  dependencies {      compile 'javax.validation:validation-api:1.1.0.final'     compile "org.hibernate:hibernate-validator:5.1.3.final"      compile "org.springframework.boot:spring-boot-starter-data-jpa:$springbootversion"      compile 'javax.ws.rs:javax.ws.rs-api:2.0.1'      compile 'org.postgresql:postgresql:9.3-1101-jdbc41'      compile "com.fasterxml.jackson.core:jackson-core:$jacksonversion"     compile "com.fasterxml.jackson.core:jackson-databind:$jacksonversion"      compile "org.springframework.boot:spring-boot-starter-web:$springbootversion"  } 

so, wrote registration user, , added validation (@notempty login , password, @email) rest params, validation not performed :(, send request invalid param password="" , request runs without errors :(, why? set validation @notempty password , if set password="" or null must see error! becouse set validation. me, please.

validation not performed on method parameters. move pojo annotate @valid , @modelattributes , you'll fine.

something like

@requestmapping(value = "/registration", method = requestmethod.post) public @responsebody boolean registration(@valid foobar foobar) { }  static class foobar {    @notempty   string login;    @notempty   string password;    @email(canbenullorempty = true)   string email;    // getter & setter  }
