hibernate 基于外键的1-1

public class Wife { private Long id; private String name; private Husband husband;

public class Husband { private Long id; private String name; private Wife wife;

外键保存在husband的表中

测试：

 Wife wife = new Wife();  Husband husband = new Husband();  wife.setName("wife777");  husband.setName("husband777");  husband.setWife(wife);//  wife.setHusband(husband);  sph.save(wife);  sph.save(husband);

//进行访问  Wife wife1 = sph.get(4l);  System.out.println(wife1.getName()+":"+wife1.getHusband().getName());    Husband husband1 = sph.getHusband(3l);  System.out.println(husband1.getName()+":"+husband1.getWife().getName());
