如何设置验证（org.hibernate.validator.constraints）在spring引导项目中休息？

Question

我和春天有个开机，Spring MVC和hibarnate的项目，我想验证其余参数，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，我写了登记为我的用户，并添加验证（@NotEmpty登录和密码，@电子邮件）为rest params，但验证不执行:(我发送请求与无效的参数密码=“”和请求运行没有错误:(为什么？我为密码设置了验证@NotEmpty，如果我设置了密码=“”或null，我必须看到错误！becouse设置验证。请帮助我。

验证不在方法参数上执行。只需将这些移动到POJO，然后使用@Valid和@ModelAttributes进行注释，那么您将会很好。

喜欢的东西

@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 

}
