试图用 JUnit 测试和模型对象找出无法解释的错误

Question

我正在对几个 java 对象建模，这些对象使用 JDBCTemplate 在 mySQL 数据库中管理实体。

我对另外两个对象进行了运行 Add/Get JUnit 测试，我没有收到任何错误，但我无法弄清楚是什么导致了我的 'Organization' 对象出现此错误。

这是我的 'Organization' dto 代码：

package com.sg.superherosightings.model;

import java.util.Objects;

public class Organization {
    
    private int orgId;
    private String orgName;
    private String orgDescription;
    private String orgPhone;
    private String orgEmail;
    private String orgStreetAddress;
    private String orgCity;
    private String orgState;
    private String orgZipCode;

    
    
    public int getOrgId() {
        return orgId;
    }

    public void setOrgId(int orgId) {
        this.orgId = orgId;
    }

    public String getOrgName() {
        return orgName;
    }

    public void setOrgName(String orgName) {
        this.orgName = orgName;
    }

    public String getOrgDescription() {
        return orgDescription;
    }

    public void setOrgDescription(String orgDescription) {
        this.orgDescription = orgDescription;
    }

    public String getOrgPhone() {
        return orgPhone;
    }

    public void setOrgPhone(String orgPhone) {
        this.orgPhone = orgPhone;
    }

    public String getOrgEmail() {
        return orgEmail;
    }

    public void setOrgEmail(String orgEmail) {
        this.orgEmail = orgEmail;
    }

    public String getOrgStreetAddress() {
        return orgStreetAddress;
    }

    public void setOrgStreetAddress(String orgStreetAddress) {
        this.orgStreetAddress = orgStreetAddress;
    }

    public String getOrgCity() {
        return orgCity;
    }

    public void setOrgCity(String orgCity) {
        this.orgCity = orgCity;
    }

    public String getOrgState() {
        return orgState;
    }

    public void setOrgState(String orgState) {
        this.orgState = orgState;
    }

    public String getOrgZipCode() {
        return orgZipCode;
    }

    public void setOrgZipCode(String orgZipCode) {
        this.orgZipCode = orgZipCode;
    }

    
    
    @Override
    public int hashCode() {
        int hash = 7;
        hash = 89 * hash + this.orgId;
        hash = 89 * hash + Objects.hashCode(this.orgName);
        hash = 89 * hash + Objects.hashCode(this.orgDescription);
        hash = 89 * hash + Objects.hashCode(this.orgPhone);
        hash = 89 * hash + Objects.hashCode(this.orgEmail);
        hash = 89 * hash + Objects.hashCode(this.orgStreetAddress);
        hash = 89 * hash + Objects.hashCode(this.orgCity);
        hash = 89 * hash + Objects.hashCode(this.orgState);
        hash = 89 * hash + Objects.hashCode(this.orgZipCode);
        return hash;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null) {
            return false;
        }
        if (getClass() != obj.getClass()) {
            return false;
        }
        final Organization other = (Organization) obj;
        if (this.orgId != other.orgId) {
            return false;
        }
        if (!Objects.equals(this.orgName, other.orgName)) {
            return false;
        }
        if (!Objects.equals(this.orgDescription, other.orgDescription)) {
            return false;
        }
        if (!Objects.equals(this.orgPhone, other.orgPhone)) {
            return false;
        }
        if (!Objects.equals(this.orgEmail, other.orgEmail)) {
            return false;
        }
        if (!Objects.equals(this.orgStreetAddress, other.orgStreetAddress)) {
            return false;
        }
        if (!Objects.equals(this.orgCity, other.orgCity)) {
            return false;
        }
        if (!Objects.equals(this.orgState, other.orgState)) {
            return false;
        }
        if (!Objects.equals(this.orgZipCode, other.orgZipCode)) {
            return false;
        }
        return true;
    }

   

   
    
    
}

这是我的 DaoDBImpl 中的 Mapper 方法： img of OrgMapper Method before fix

这是我的 SuperSightings_DaoTest 方法导致的错误：

这是我遇到的错误：

如果我需要提供更多信息，请告诉我。我正在努力更好地了解我 post 在这里提出的问题。我在询问之前搜索了很长时间，但我所能找到的只是它可能与我的 equals/hash 代码有关。我只是不确定进行比较时发生了什么变化，因为我的其他对象没有发生这种情况。

感谢您的任何提示，请不要咬我的头！

Answer 1

好像有些字段不相等。尝试一一比较所有字段以识别不相等的字段：assertEquals(fromDao.getOrgId(), org.getOrgId() 和组织的所有其他字段)

Answer 2

谢谢大家的帮助！我能够将我的 org 和 fromDao 对象转换为字符串，以便在测试中看到它们 window。问题出在我的 Organization 对象的 Mapper 方法上。请参阅下面的原始内容和修复程序：

原版

    private static final class OrgMapper implements RowMapper<Organization> {
        
        @Override
        public Organization mapRow(ResultSet rs, int i) throws SQLException {
            Organization org = new Organization();
            org.setOrgId(rs.getInt("org_id"));
            org.setOrgName(rs.getString("org_name"));
            org.setOrgDescription(rs.getString("org_description"));
            org.setOrgPhone(rs.getString("org_phone"));
            org.setOrgEmail(rs.getString("org_street_address")); //wrong field
            org.setOrgCity(rs.getString("org_city"));
            org.setOrgState(rs.getString("org_state"));
            org.setOrgZipCode(rs.getString("org_zip_code"));
            
            return org;
        
        }    
    }

修复了 OrgMapper：

    private static final class OrgMapper implements RowMapper<Organization> {
        
        @Override
        public Organization mapRow(ResultSet rs, int i) throws SQLException {
            Organization org = new Organization();
            org.setOrgId(rs.getInt("org_id"));
            org.setOrgName(rs.getString("org_name"));
            org.setOrgDescription(rs.getString("org_description"));
            org.setOrgPhone(rs.getString("org_phone"));
            org.setOrgEmail(rs.getString("org_email"));
            org.setOrgStreetAddress(rs.getString("org_street_address"));
            org.setOrgCity(rs.getString("org_city"));
            org.setOrgState(rs.getString("org_state"));
            org.setOrgZipCode(rs.getString("org_zip_code"));
            
            return org;
        
        }
