# 1、第一层对象定义 #

import java.io.Serializable;
    
    import javax.validation.Valid;
    
    /**   
     * 请求参数
     * @Title: ReqIn.java 
     * @Package com.spring.pro.model 
     * @Description:  
     * @author ybwei  
     * @date 2018年9月18日 下午1:43:26 
     * @version V1.0   
     */
    public class ReqIn<T> implements Serializable{
    
    	private static final long serialVersionUID = 25549320423002325L;
    	/**
    	 * 请求头信息
    	 */
    	private String head;
    	/**
    	 * 请求主体信息
    	 */
    	@Valid
    	private T data;
    	public String getHead() {
    		return head;
    	}
    	public void setHead(String head) {
    		this.head = head;
    	}
    	public T getData() {
    		return data;
    	}
    	public void setData(T data) {
    		this.data = data;
    	}
    }

# 2、第二层对象 #

import java.io.Serializable;
    
    import javax.validation.constraints.NotBlank;
    import javax.validation.constraints.NotNull;
    
    /**   
     * @Title: User.java 
     * @Package com.spring.pro.model 
     * @Description:  
     * @author ybwei  
     * @date 2018年9月18日 下午1:46:15 
     * @version V1.0   
     */
    public class User implements Serializable{
    
    	private static final long serialVersionUID = 6747944028911495569L;
    	private String id;
    	@NotBlank
    	private String name;
    	@NotNull
    	private Integer age;
    	public String getId() {
    		return id;
    	}
    	public void setId(String id) {
    		this.id = id;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public Integer getAge() {
    		return age;
    	}
    	public void setAge(Integer age) {
    		this.age = age;
    	}
    }

# 3、Controller层校验使用 #

import javax.validation.Valid;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.http.HttpStatus;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RestController;
    
    import com.alibaba.fastjson.JSON;
    import com.spring.pro.model.ReqIn;
    import com.spring.pro.model.User;
    
    /**   
     * @Title: UserController.java 
     * @Package com.spring.pro.controller 
     * @Description:  
     * @author ybwei  
     * @date 2018年9月18日 下午1:48:14 
     * @version V1.0   
     */
    @RestController
    public class UserController {
    	private Logger logger=LoggerFactory.getLogger(getClass());
    
    	/**
    	 * 校验
    	 * @param reqIn
    	 * @return
    	 * @author ybwei
    	 */
    	@PostMapping("/valid")
    	public HttpStatus valid(@Valid @RequestBody ReqIn<User> reqIn){
    		logger.info("reqIn:{}",JSON.toJSONString(reqIn));
    		return HttpStatus.OK;
    	}
    }
