Spring3整合Hibernate3.6之一：简单CRUD
本来是想拿Spring整合Hibernate4的，事实证明我道行尚浅 未遂……
看到这个异常，且在用Hibernate4的同学就要考虑Hibernate的版本问题了
（解决完这个问题发现4里边把HibernateTemplate取消掉了，所以就没再死扣）。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ' XXXXX ': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateTemplate' defined in class path resource [applicationContext-common.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider;
原来弄过spring+ibatis的整合，其实道理差不多
都是spring帮忙注入，OR框架去数据库中CRUD，仅有的一点区别就是ibatis的SQL是手动的，Hibernate的HQL是自动的，所以Hibernate要实体Student用Annotation声明一下
用Hibernate的方式，声明实体、表名、主键等。
工程里不再需要 hibernate.cfg.xml 了，在spring配置文件的：hibernateProperties标签里配置就行了
public class StudentServiceTest {@Testpublic void testAdd() throws Exception {//Spring读取spring配置信息ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-common.xml");//相当于从代理类得到具体实例，由xml决定怎么选择类实例化StudentService service01 = (StudentService)ctx.getBean("StudentService");Student stu = new Student();//手动组装User实例 u//stu.setStudentid(？？？); 用自动增长序列stu.setName("Spring+Hibernate");stu.setAge(777);service01.add(stu);//把组装好的u传给xml实例化的servicectx.destroy();}@Testpublic void testDelById() throws Exception {ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-common.xml");StudentService service01 = (StudentService)ctx.getBean("StudentService");service01.delById(23);//只需要把id传给实例化的servicectx.destroy();}@Testpublic void testGetAll() throws Exception {ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-common.xml");StudentService service01 = (StudentService)ctx.getBean("StudentService");System.out.println("查询全部：");List<Student> stusAll = (List<Student>)service01.getAll();for(int i=0;i<stusAll.size();i++){System.out.println(stusAll.get(i));}ctx.destroy();}@Testpublic void testUpdateStudent() throws Exception {ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-common.xml");StudentService service01 = (StudentService)ctx.getBean("StudentService");Student stu = new Student();//手动组装User实例 ustu.setStudentid(25);stu.setName("SH");stu.setAge(777);service01.updateStudent(stu);//把组装好的u传给spring实例化的servicectx.destroy();}@Testpublic void testSelectByName() throws Exception {ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-common.xml");StudentService service01 = (StudentService)ctx.getBean("StudentService");System.out.println("查询全部：");String name = "SH";List<Student> stusAll = (List<Student>)service01.selectByName(name);for(int i=0;i<stusAll.size();i++){System.out.println(stusAll.get(i));}ctx.destroy();}}
