package com.yl.validation.model;
import com.yl.validation.validation.ValidationGroup1;
import com.yl.validation.validation.ValidationGroup2;
import javax.validation.constraints.*;
import java.io.Serializable;
public class User implements Serializable {
private Integer id;
//校验字符串长度
@Size(min = 3,max = 8,message = "{user.username.size}",groups = ValidationGroup1.class)
private String username;
//非空校验
@NotNull(message = "{user.password.notnull}")
private String password;
//数值范围校验
@DecimalMin(value = "15",message = "{user.age.min}",groups = {ValidationGroup1.class, ValidationGroup2.class})
@DecimalMax(value = "30",message = "{user.age.max}",groups = {ValidationGroup1.class, ValidationGroup2.class})
private Integer age;
//非空校验
@NotNull(message = "{user.email.notnull}")
//邮箱格式校验
@Email(message = "{user.email.pattern}")
private String email;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", username='" + username + '\'' +
", password='" + password + '\'' +
", age=" + age +
", email='" + email + '\'' +
'}';
}
}3.controller
package com.yl.validation.controller;
import com.yl.validation.model.User;
import com.yl.validation.validation.ValidationGroup1;
import com.yl.validation.validation.ValidationGroup2;
import org.springframework.validation.BindingResult;
import org.springframework.validation.ObjectError;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@RestController
public class UserController {
@PostMapping("/addUser")
public void addUser(@Validated(ValidationGroup2.class) User user, BindingResult result) {
if (result != null && result.hasErrors()) {
List<ObjectError> allErrors = result.getAllErrors();
for (ObjectError objectError : allErrors) {
System.out.println(objectError.getDefaultMessage());
}
}
}
}4.ValidationMessages.Properties,手动新建放在resources目录下
user.username.size=用户名的长度应为3到8
user.password.notnull=密码不能为空
user.age.min=年龄最小值为15
user.age.max=年龄最大值为30
user.email.notnull=邮箱不能为空
user.email.pattern=邮箱格式不正确5.组一
package com.yl.validation.validation;
public interface ValidationGroup1 {
}6.组二
package com.yl.validation.validation;
public interface ValidationGroup2 {
}7.测试结果，由于分了组，发现只有年龄校验有效！
