springmvc中DAO中save方法与数据库

save方法:
public void save(T o){

    getSession().save(o);

}

controller里的方法:
@RequestMapping(value = "/fileUpload2.do", method = RequestMethod.POST)

public String fileUpload2(Long id,Video video,ModelMap map,HttpServletRequest request)

throws IllegalStateException, IOException {

System.out.println("id是"+id);
// 设置上下方文

CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(

request.getSession().getServletContext());
System.out.println("2");
// 检查form是否有enctype="multipart/form-data"

if (multipartResolver.isMultipart(request)) {

MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;

System.out.println("3");
Iterator iter = multiRequest.getFileNames();

while (iter.hasNext()) {

// 由CommonsMultipartFile继承而来,拥有上面的方法.

MultipartFile file = multiRequest.getFile(iter.next());

if (file != null) {

String videoname = "Upload" + file.getOriginalFilename();
video.setvideoname(videoname);
String path = "E:/" + videoname;

video.setPath(path);
File localFile = new File(path);

file.transferTo(localFile);
System.out.println("4");
}

}

}
Long Tid=id;
map.addAttribute("id", id);
map.addAttribute("Tid", Tid);
video.setTid(Tid);
System.out.println("视频路径是1"+video.getPath());
System.out.println("视频Tid是1"+video.getTid());
videoService.save(video);
System.out.println("视频路径是2"+video.getPath());
System.out.println("视频Tid是2"+video.getTid());
return "main/homework";

}

控制台打印信息是正确的,但是数据库中没有插入相应信息。有木有大神指点?挺急的,在线等。

dao层代码呢?你怎么插进去的啊?不会是走了 getSession().save(o);

这个吧?这个不是插数据库的啊,你点进去看看这个save方法是实现什么的

不常发疯的疯子 那个save方法就是dao层的,save不是添加新数据的吗?

数据库相关的配置中有没有设置自动提交呢,如果没有的话,还需要在save操作后面添加commit操作的。

这个不是插数据库.可以看看其他

关于Springmvc数据库插入的问题
现在遇到一个很奇怪的问题。我的dao和service都有一个基础类 里面定义了增加和查询的方法 然后我两个表的dao和service都去继承这个类。User表可以正常的添加和查询。另一个表只能查询不能添加。。也不会报错。。求解为什么会这样。。 以下是基础DAO类的插入代码 public PK save(T entity) { Assert.notNull(entity, "entity is required"); getSession().save(entity); getSession().close(); return (PK) getSession().save(entity); }
SpringMVC结构有没有可能在不基于XML的方式中与数据库发生交互?
小弟之前使用Sping框架的时候SQL语言都是写在XML中的,如: ``` <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd"> <mapper namespace="com.sdzw.dao.AdminsMapper"> <!-- findAdminName --> <!-- 根据传入的adminname查找相关的信息 --> <select id="findAdminName" parameterType="java.lang.String" resultType="com.sdzw.entity.Admins"> SELECT * FROM admins WHERE admin_name= #{adminName} </select> <!-- save --> <!-- 保存新建的管理员账户 --> <insert id="save" parameterType="com.sdzw.entity.Admins"> INSERT INTO admins VALUES (#{admin_id},#{admin_name}, #{admin_password},#{admin_nickname}) </insert> <!-- update --> <!-- 对已经存在的用户信息进行修改 --> <update id="update" parameterType="com.sdzw.entity.Admins"> UPDATE admins SET admin_name=#{admin_name},admin_password=#{admin_password},admin_nickname=#{admin_nickname} WHERE admin_id=#{admin_id} </update> </mapper> ``` 现在领导要求将代码写死在Java语言中,还要使用Spring框架,请问有没有解决的办法

sessionFactory; } public Session getSession() { //事务配置后,可通过getCurrentSession方法获得session return sessionFactory.getCurrentSession(); } public int executeUpdateBySql(final String sql,final List<Object>

!conditions.get(i).equals("")){ query.setParameter(i, conditions.get(i)); } } } return query.executeUpdate(); } catch (RuntimeException e) { throw e; }finally{ System.out.println(getSessionFactory().getCurrentSession().beginTransaction().isActive()); } } 整体代码是这样的,在运行daoImpl.java中test()方法的时候执行第一条SQL时会提交事物,直接修改数据库中的值,执行第二条SQL时会报错,理论上应该都不提交事物。但实际上第一条执行了之后就提交事物了,不知道是我框架问题还是我写的问题,求大神帮忙指出问题所在。万分感谢! ```
