问题描述
我正在对使用 JDBCTemplate 管理 MysqL 数据库中的实体的多个 Java 对象进行建模。
我已经在另外两个对象上运行了 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“组织”对象出现此错误。
这是我的“组织”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;
}
}
这是我在 DaoDBImpl 中的 Mapper 方法： img of OrgMapper Method before fix
这是我的 SuperSightings_DaoTest 方法导致错误：

dao.deleteSighting(currentSighting.getSightingId());
}
}
@After
public void tearDown() {
}
/**

@Test
public void testAddGetPower() {
Power power = new Power();
power.setPowerType("Fire");
power.setPowerDescription("Shoots fire from hands");
dao.addPower(power);
Power fromDao = dao.getPowerById(power.getPowerId());
assertEquals(fromDao,power);
}

assertEquals(fromDao,power);
dao.deletePower(power.getPowerId());
assertNull(dao.getPowerById(power.getPowerId()));
}

@Test
public void testGetAllPowersBySupeId() {
}

@Test
public void testAddGetorganization() {
Organization org = new Organization();
org.setorgName("Legion of Doom");
org.setorgDescription("evil organization");
org.setorgPhone("333-444-5678");
org.setorgEmail("lod@evil.org");
org.setorgStreetAddress("344 Lowland Blvd.");
org.setorgCity("Quahog");
org.setorgState("RI");
org.setorgZipCode("09678");
dao.addOrganization(org);
Organization fromDao = dao.getorganizationById(org.getorgId());
assertEquals(fromDao,org); //this is the line causing the error
}
这是我得到的错误：
testAddGetorganization(com.sg.superherosightings.dao.SuperSightings_DaoTest) 已用时间：0.107 秒
如果我需要提供更多信息，请告诉我。我正在努力改进我在这里发布问题的方式。在询问之前我搜索了很长时间，但我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会发生什么变化，因为我的其他对象没有发生这种情况。
谢谢你的任何提示，请不要咬我的头！
解决方法
似乎有些字段不相等。尝试将所有字段一一比较以识别不相等的字段： assertEquals(fromDao.getOrgId(),org.getOrgId() 和组织的所有其余字段)
,感谢大家的帮助！我能够将我的 org 和 fromDao 对象转换为字符串以在测试窗口中查看它们。问题出在我的组织对象的 Mapper 方法上。请参阅下面的原始和修复程序：
原始版本
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;
}
}
固定 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;
}
