?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());
