验证来自 REST API 调用的响应

Question

我正在处理响应映射的错误。在继续将响应映射到我的域对象之前，我想验证响应。检查错误。

我计划创建一个 Validator.java 类并为每个 API 调用实现验证方法。

春天有没有其他方法可以做到这一点？

package com.people.net;


import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.Email;


public class UserInfo {
    //Unicode check
    @Pattern(regexp="[0-9a-zA-Z\\s-]+", message="chars,numbers allowed only")
    String name;
    int id;

    @Pattern(regexp="([0-9]{10})", message="minLength=maxLength=10 only numbers")
    String pin;

    @Email
    String email;

    @Size(max=5, message="5 chars max")
    String emailType;
    @Size(max=5, message="5 chars max")
    String addressType;

    @Size(max=300, message="5 chars max")
    String address;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    public UserInfo(String name, String pin, String id) {
        super();
        this.id = Integer.parseInt(id);
        this.name = name;
        this.pin = pin;
    }
    public UserInfo(int id,String name, String pin, String email, String emailType, String addressType, String address) {
        super();
        this.id = id;
        this.name = name;
        this.pin = pin;
        this.email = email;
        this.emailType = emailType;
        this.addressType = addressType;
        this.address = address;
    }
    public UserInfo() {

    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getPin() {
        return pin;
    }
    public void setPin(String pin) {
        this.pin = pin;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getEmailType() {
        return emailType;
    }
    public void setEmailType(String emailType) {
        this.emailType = emailType;
    }
    public String getAddressType() {
        return addressType;
    }
    public void setAddressType(String addressType) {
        this.addressType = addressType;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }



}

您应该探索休眠验证器，它是用于 bean 验证的参考实现 JSR-349。更多信息在这里https://jcp.org/en/jsr/detail?id=349。

此外，hibernate 验证器是进行 bean 验证的行业标准（互联网上有很多可用的东西），并带有许多流行的框架，如 dropwizard 等。它提供基于注释的验证，并允许您编写自己的基于注释的自定义验证.
