如何設置驗證（org.hibernate.validator.constraints）在spring引導項目中休息？

Question

我和春天有個開機，Spring MVC和hibarnate的項目，我想驗證其餘參數，可以我有控制器：

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 with params login = " + login 
       + ", password = " + password + ", email = " + email); 
     return !userService.findByLoginAndPassword(login, password) 
       && userService.addUser(new User(login, password, email)); 
    } 

} 

和我的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" 

} 

所以，我寫了登記爲我的用戶，並添加驗證（@NotEmpty登錄和密碼，@電子郵件）爲rest params，但驗證不執行:(我發送請求與無效的參數密碼=「」和請求運行沒有錯誤:(爲什麼？我爲密碼設置了驗證@NotEmpty，如果我設置了密碼=「」或null，我必須看到錯誤！becouse設置驗證。請幫助我。

驗證不在方法參數上執行。只需將這些移動到POJO，然後使用@Valid和@ModelAttributes進行註釋，那麼您將會很好。

@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 

}
