#注解校验入参

注解校验提高开发速度，减少校验代码。

注解校验入参内容，提高代码整洁度，增强代码可读性，使代码结构更加优雅。

pom.xml

##实体类

SearchDomeReq

@Setter@Getter是Lombok内部注解

学习Lombok请访问https://blog.csdn.net/smd2575624555/article/details/79264405

import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;

import lombok.Getter;
import lombok.Setter;

@Setter
@Getter
public class SearchDomeReq {

    @NotBlank(message = "Parameter error: no name")
    private String name;

    @NotNull(message = "Parameter error: score is not null")
    private Double score;


}

##控制层

import javax.validation.Valid;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

public class SearchColleaction {

	@RequestMapping(value = "/by/feature", method = RequestMethod.POST, headers = "Accept=application/json")
    @ResponseBody
    //一定要加@Valid ，不然不生效
    public String searchByFeature(@Valid @RequestBody SearchDomeReq searchNReq) {
		String result=searchNReq.getName()+"同学得分为："+searchNReq.getScore()
  
        return result;
    }
}
