java - java中junit测试中的断言错误

Question

伙计们，我有这项服务

public class DepartmentServiceImpl implements DepartmentService {

    @Autowired
    private DepartmentDao departmentDao;
    //... other functions 

    @Override
    public Department getDepartment(int depid) {
        return departmentDao.getDepartment(depid);
    }
}

我的测试单元是

Department department = new Department();

@Autowired
private DepartmentDao myDao;

@Autowired
private DepartmentService service;


@Test
public void testGetDepartment(){
    department.setDepId(111);
    department.setDepName("merna");
    assertEquals(department, service.getDepartment(111));
}

但它给了我

java.lang.AssertionError: expected:<com.dineshonjava.model.Department@f9b5552> but was:<com.dineshonjava.model.Department@4d4960c8>

有什么帮助吗？

您应该重写 Department 类中的 equals 方法:

public boolean equals(Object object) {
      if(object == null) {
          return false;
      } 
      if(this == object) {
          return true;
      }
      Department otherDepartment = (Department) object;
      if(this.getDepId() == otherDepartment.getDepId()) {
          return true;
      } else {
          return false;
      }
}
