测试开发进阶——spring boot——MVC——Spring MVC框架的数据验证——示例

控制器：

package com.awaimai.web;

import org.hibernate.validator.constraints.*;
import org.springframework.validation.BindingResult;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.validation.Valid;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.Size;
import java.util.Enumeration;

@RestController
@Validated
public class kzq
{


    @RequestMapping(value ="/test2")
    public String test2( @Valid Student student, BindingResult bindingResult)
    {
        String a = student.getFirstName();
        String b = student.getLastName();
        return a+b;
    }




}

　　

实体类：

package com.awaimai.web;

import org.springframework.validation.annotation.Validated;

import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;


public class Student
{

    @Size(min = 2,max = 5)
    private String firstName;

    @NotNull
    @Size(min = 2,max = 3)
    private String lastName;

    public void setFirstName(String firstName)
    {
        this.firstName = firstName;
    }

    public String getFirstName()
    {
        return firstName;
    }

    public void setLastName(String lastName)
    {
        this.lastName = lastName;
    }

    public String getLastName()
    {
        return lastName;
    }

}
