java - Java assertEquals 导致 JUnit 测试失败
问题描述
我正在 Netbeans 中处理一个 java jdbcTemplate 项目，我无法弄清楚我的 equals 和 hashcode 方法有什么问题，这些方法覆盖了我的 Dao 的 assertEquals 测试。我被告知我需要对对象进行“深度比较”，但据我所知，我的代码已经在这样做了。以下是涉及此问题的不同课程
这是我的Organization.class：
public class Organization {
private int orgId;
private String orgName;
private String orgDescription;
private String orgEmail;
private String orgPhone;
private Location orgLocation;
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 getOrgEmail() {
return orgEmail;
}
public void setOrgEmail(String orgEmail) {
this.orgEmail = orgEmail;
}
public String getOrgPhone() {
return orgPhone;
}
public void setOrgPhone(String orgPhone) {
this.orgPhone = orgPhone;
}
public Location getOrgLocation() {
return orgLocation;
}
public void setOrgLocation(Location orgLocation) {
this.orgLocation = orgLocation;
}
@Override
public int hashCode() {
int hash = 7;
hash = 67 * hash + this.orgId;
hash = 67 * hash + Objects.hashCode(this.orgName);
hash = 67 * hash + Objects.hashCode(this.orgDescription);
hash = 67 * hash + Objects.hashCode(this.orgEmail);
hash = 67 * hash + Objects.hashCode(this.orgPhone);
hash = 67 * hash + Objects.hashCode(this.orgLocation);
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.orgEmail, other.orgEmail)) {
return false;
}
if (!Objects.equals(this.orgPhone, other.orgPhone)) {
return false;
}
if (!Objects.equals(this.orgLocation, other.orgLocation)) {
return false;
}
return true;
}
}
这是我的组织道实现：
public class OrgDaoDBImpl implements OrgDao{
private JdbcTemplate jdbcTemplate;
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
//ORGANIZATIONS - PREPARED STATEMENTS
private static final String SQL_INSERT_ORGANIZATION
= "insert into `organization` (org_name, org_description, org_email, "
+ "org_phone, location_id) "
+ "values (?, ?, ?, ?, ?)";
private static final String SQL_DELETE_ORGANIZATION
= "delete from `organization` where org_id = ?";
private static final String SQL_UPDATE_ORGANIZATION
= "update `organization` set org_name = ?, org_description = ?, org_email = ?, "
+ "org_phone = ?, location_id = ? "
+ "where org_id = ?";
private static final String SQL_SELECT_ORGANIZATION
= "select * from `organization` where org_id = ?";
private static final String SQL_SELECT_ALL_ORGANIZATIONS
= "select * from `organization`";
private static final String SQL_SELECT_LOCATION_BY_ORG_ID
= "select l.location_id, l.loc_name, l.loc_street_address, "
+ "l.loc_city, l.loc_state, l.loc_zip_code, l.loc_lat, l.loc_long "
+ "from location l "
+ "join organization o on l.location_id = o.location_id "
+ "where o.org_id = ?";
@Override
@Transactional(propagation = Propagation.REQUIRED, readOnly = false)
public void addOrganization(Organization organization) {
jdbcTemplate.update(SQL_INSERT_ORGANIZATION,
organization.getOrgName(),
organization.getOrgDescription(),
organization.getOrgPhone(),
organization.getOrgEmail(),
organization.getOrgLocation().getLocationId());
organization.setOrgId(
jdbcTemplate.queryForObject("select LAST_INSERT_ID()", Integer.class));
}
@Override
public void deleteOrganization(int organizationId) {
jdbcTemplate.update(SQL_DELETE_ORGANIZATION, organizationId);
}
@Override
public void updateOrganization(Organization organization) {
jdbcTemplate.update(SQL_UPDATE_ORGANIZATION,
organization.getOrgName(),
organization.getOrgDescription(),
organization.getOrgPhone(),
organization.getOrgEmail(),
organization.getOrgLocation().getLocationId());
}
@Override
public Organization getOrganizationById(int id) {
try {
Organization org = jdbcTemplate.queryForObject(SQL_SELECT_ORGANIZATION,
new OrgMapper(),
id);
org.setOrgLocation(findLocationForOrganization(org));
return org;
} catch (EmptyResultDataAccessException ex) {
return null;
}
}
@Override
public List<Organization> getAllOrganizations() {
return jdbcTemplate.query(SQL_SELECT_ALL_ORGANIZATIONS, new OrgMapper());
}
@Override
public List<Organization> getAllOrgsBySupeId(int supeId) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.

Location loc = new Location();
loc.setLocationId(rs.getInt("location_id"));

loc.setLocZipCode(rs.getString("loc_zip_code"));
loc.setLocLat(rs.getString("loc_lat"));
loc.setLocLong(rs.getString("loc_long"));
return loc;
}
}
}
我的 Organization.class 使用 Location 对象来输入其他位置信息。因此，在下面，我首先必须添加一个位置，然后再尝试添加一个组织。目前，添加位置测试成功。
public class SuperSighting_DaoTests {
LocationDao ldao;
OrgDao odao;
PowerDao pdao;
SightingDao sidao;
SupeDao sudao;
public SuperSighting_DaoTests() {
}
@BeforeClass
public static void setUpClass() {
}
@AfterClass
public static void tearDownClass() {
}
@Before
public void setUp() {
ApplicationContext ctx
= new ClassPathXmlApplicationContext("test-applicationContext.xml");
ldao = ctx.getBean("LocationDao", LocationDao.class);
odao = ctx.getBean("OrgDao", OrgDao.class);
pdao = ctx.getBean("PowerDao", PowerDao.class);
sidao = ctx.getBean("SightingDao", SightingDao.class);
sudao = ctx.getBean("SupeDao", SupeDao.class);
// delete all supes
List<Supe> supes = sudao.getAllSupes(); for (Supe currentSupe : supes) {
sudao.deleteSupe(currentSupe.getSupeId());
}
// delete all powers
List<Power> powers = pdao.getAllPowers(); for (Power currentPower : powers) {
pdao.deletePower(currentPower.getPowerId());
}
//delete all organizations
List<Organization> orgs = odao.getAllOrganizations(); for (Organization currentOrg : orgs) {
odao.deleteOrganization(currentOrg.getOrgId());
}
// delete all locations
List<Location> locations = ldao.getAllLocations(); for (Location currentLocation : locations) {
ldao.deleteLocation(currentLocation.getLocationId());
}
// delete all sightings
List<Sighting> sightings = sidao.getAllSightings(); for (Sighting currentSighting : sightings) {
sidao.deleteSighting(currentSighting.getSightingId());
}
}
@Test
public void testAddGetOrganization() {
Location loc = new Location();
loc.setLocName("Legion of Doom");
loc.setLocStreetAddress("127 Taco St.");
loc.setLocCity("Smalltown");
loc.setLocState("MA");
loc.setLocZipCode("19698");
loc.setLocLat("39.16567925978815");
loc.setLocLong("-75.59452746539126");
ldao.addLocation(loc);
Organization org = new Organization();
org.setOrgName("Legion of Doom");
org.setOrgDescription("evil organization");
org.setOrgPhone("333-444-5678");
org.setOrgEmail("lod@evil.org");
org.setOrgLocation(loc);
odao.addOrganization(org);
Organization fromDao = odao.getOrganizationById(org.getOrgId());
fromDao.toString();
assertEquals(fromDao, org);
}
测试完成后，我可以看到比较的项目完全相同，但测试失败并给我这个错误：
测试运行：8，失败：1，错误：0，跳过：0，经过的时间：2.931 秒 <<< 失败！testAddGetOrganization(com.sg.supersightingsv2.dao.SuperSighting_DaoTests) 已用时间：0.177 秒 <<< 失败！java.lang.AssertionError：预期：com.sg.supersightingsv2.model.Organization@ad172ff9 但在 org.junit.Assert.fail(Assert.java:88) 处是：com.sg.supersightingsv2.model.Organization@e8c8a831
这是显示正在比较的两个对象（“org”和“fromDao”）的字段值的图像：正在比较的两个对象
我真的不确定从这里去哪里，因为我的最终目标取决于通过测试。我已经多次阅读了代码，除了重写整个程序之外，我不知道该怎么做。任何建议都值得赞赏，因为我还是新手！谢谢！
