hibernate4 提示user is not mapper

maven 项目 spring4 springmvc hibernate4 框架,实体类的映射文件是xml格式,我在junit 上用hibernate query接口测试查询没有问题,但是在实际的web项目中,我用的是hql查询,而且我看他那个报错,查询的也是我的那个实体类的类名,而且我也确定我的映射文件的路径也没有问题,不知道还有没有其他原因导致报这个错~

解决啦?我在一篇博文上看到,spring给hibernate注入的数据源,三种开启session的效果是不一样的,有一个开启,不支持hql

应该写模型的名称,User大写

mybatis基本问题,应用接口编程报错

初学mybatis,应用接口编程时,报了错,百度上的解决办法没用,错误如下: Exception in thread "main" org.apache.ibatis.binding.BindingException: Type interface com.yihaomen.myatis.inner.IUserOperation is not known to the MapperRegistry. at org.apache.ibatis.binding.MapperRegistry.getMapper(MapperRegistry.java:47) at org.apache.ibatis.session.Configuration.getMapper(Configuration.java:655) at org.apache.ibatis.session.defaults.DefaultSqlSession.getMapper(DefaultSqlSession.java:222) at com.yihaomen.test.Test.main(Test.java:53) user.java文件主要就是一些属性和set,get方法 User.xml文件 <mapper namespace="com.yihaomen.mybatis.models.UserMapper"> <select id="selectUseById" parameterType="int" resultType="User"> select * from user where id = #{id} </select> <select id="selectUser" parameterType="int" resultType="User"> select * from user </select> </mapper> 接口IUserOperation.java文件 public interface IUserOperation { public User selectUseById(int id); } 还有主要的Configuration.xml文件 测试类Test.java public static void main(String[] args){ SqlSession session = sqlSessionFactory.openSession(); try { IUserOperation userOperation=session.getMapper(IUserOperation.class); User user = userOperation.selectUseById(1); System.out.println(user.getUserAddress()); System.out.println(user.getUserName()); } finally { session.close(); } } ,其它的获取sqlsessionfactory,打开session等就没写,报错的就是IUserOperation userOperation=session.getMapper(IUserOperation.class);这一句 请问到底是什么原因,如何解决

mybatis通用mapper问题报错

有两个表, user id,username,password ,Set<ROLE> roles role id,role_name,role_code 继承通用mapper报错。No typehandler found for property roles 去掉,Set<ROLE> roles 这个 就没事. 应该怎么配置?

请教一下,到底我的mapper.xml哪里出错了,弄不明白为什么找不到我写的log类

## update一下经大佬提点后如何解决的 可能因为我曾用粗暴的方法改动过Log.java的类名,导致Log类编译出问题了,编译后类文件夹内根本没有Log.class文件。于是我又粗暴地delete了Log类重写了一次,果然没问题了。 顺便百度了一下如何修改类名 https://zhidao.baidu.com/question/340215163.html ## 原问题如下 小白入门程序媛,这个是一个mybatis的关于银行转账的小练习 在写log部分之前,我写的account部分测试过是没有问题的,转账的业务也成功了的。现在是想增加一个记录日志的操作,在数据库log表格添加转账记录,并且利用log4j在硬盘生成log file中记录转账信息。 可是按照同样的套路写了了log实体类后再写logmapper.xml,却出现了以下的错误,后来干脆连mybatis中的别名的部分都去掉了,直接在mapper.xml中使用完整的类名,还是说找不到我写的log类。实在搞不懂是namespace出错了还是怎么滴。。。。 ## 错误信息如下: ``` 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Server version: Apache Tomcat/8.5.42 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Server built: Jun 4 2019 20:29:04 UTC 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Server number: 8.5.42.0 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: OS Name: Windows 10 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: OS Version: 10.0 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Architecture: amd64 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Java Home: C:\Program Files\Java\jdk1.8.0_201\jre 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: JVM Version: 1.8.0_201-b09 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: JVM Vendor: Oracle Corporation 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: CATALINA_BASE: D:\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: CATALINA_HOME: D:\apache-tomcat-8.5.42 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Command line argument: -Dcatalina.base=D:\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Command line argument: -Dcatalina.home=D:\apache-tomcat-8.5.42 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Command line argument: -Dwtp.deploy=D:\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Command line argument: -Djava.endorsed.dirs=D:\apache-tomcat-8.5.42\endorsed 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.VersionLoggerListener log 信息: Command line argument: -Dfile.encoding=UTF-8 七月 13, 2019 8:47:00 下午 org.apache.catalina.core.AprLifecycleListener lifecycleEvent 信息: Loaded APR based Apache Tomcat Native library [1.2.21] using APR version [1.6.5]. 七月 13, 2019 8:47:00 下午 org.apache.catalina.core.AprLifecycleListener lifecycleEvent 信息: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true]. 七月 13, 2019 8:47:00 下午 org.apache.catalina.core.AprLifecycleListener lifecycleEvent 信息: APR/OpenSSL configuration: useAprConnector [false], useOpenSSL [true] 七月 13, 2019 8:47:00 下午 org.apache.catalina.core.AprLifecycleListener initializeSSL 信息: OpenSSL successfully initialized [OpenSSL 1.1.1a 20 Nov 2018] 七月 13, 2019 8:47:00 下午 org.apache.coyote.AbstractProtocol init 信息: Initializing ProtocolHandler ["http-nio-8080"] 七月 13, 2019 8:47:00 下午 org.apache.tomcat.util.net.NioSelectorPool getSharedSelector 信息: Using a shared selector for servlet write/read 七月 13, 2019 8:47:00 下午 org.apache.coyote.AbstractProtocol init 信息: Initializing ProtocolHandler ["ajp-nio-8009"] 七月 13, 2019 8:47:00 下午 org.apache.tomcat.util.net.NioSelectorPool getSharedSelector 信息: Using a shared selector for servlet write/read 七月 13, 2019 8:47:00 下午 org.apache.catalina.startup.Catalina load 信息: Initialization processed in 828 ms 七月 13, 2019 8:47:00 下午 org.apache.catalina.core.StandardService startInternal 信息: Starting service [Catalina] 七月 13, 2019 8:47:00 下午 org.apache.catalina.core.StandardEngine startInternal 信息: Starting Servlet Engine: Apache Tomcat/8.5.42 七月 13, 2019 8:47:01 下午 org.apache.jasper.servlet.TldScanner scanJars 信息: At least one JAR was scanned for TLDs yet contained no TLDs.

关于hibernate的一个批量操作

我在做项目遇到一个很经典的问题,就是用hibernate做批量插入的问题。 方法1: 读取一行数据,dao保存一行数据,所有的保存放在一个事务; 方法2:读取所有的数据,拼接成一个hql,一次性执行; 请问那个效率会好一点?

mybatis下为什么我的mapper标签里面没有代码提示

![图片说明](https://img-ask.csdn.net/upload/201605/24/1464067706_645486.png)

求大神赐教Mapper mapper.map

@Resource private Mapper mapper; 表示什么意思 @Override public CxbbabaUserInfoModel getUserInfoByUserId(Long userId){ Criterion criterion = and(CxbbabaUserinfoEntity.UserID.eq(userId)); CxbbabaUserinfoEntity entity = userInfoRepository.where(criterion).singleOrDefault(); if (entity != null) { return mapper.map(entity, CxbbabaUserInfoModel.class); } return null; } 这段代码每行各代表什么意思???特别是return mapper.map(entity, CxbbabaUserInfoModel.class);这行代码,表示的是什么意思????

springboot项目中使用了mybatisplus的baseMapper中的方法,却提示报错自己的mapper中没有这个方法

报错信息如下: Invalid bound statement (not found): cn.itsource.fastgo.mapper.EmployeeMapper.selectOne 这是service层的接口实现类 @Service @Transactional(readOnly = true,propagation = Propagation.SUPPORTS) public class EmployeeServiceImpl extends ServiceImpl<EmployeeMapper,Employee> implements IEmployeeService { @Override public Employee login(String username, String password) { return baseMapper.selectOne(new QueryWrapper<Employee>() .eq("username",username) .eq("password",password)); } } 这是mapper @Mapper public interface EmployeeMapper extends BaseMapper<Employee> { } 这是controller @RestController public class LoginController { @Autowired private IEmployeeService employeeService; @PostMapping("/login") @ApiOperation(value = "登录接口" + "") public AjaxResult login(@RequestBody Map<String,Object> params){ String username = (String) params.get("username"); String password = (String) params.get("password"); Employee employee = employeeService.login(username,password); if(null!=employee){ //登录成功 return AjaxResult.me(); } //登录失败 return AjaxResult.me().setSuccess(false).setMessage("用户名或密码错误!"); } } 请问大神们为什么调用的是basemapper的selectOne方法,但是会报错employeeMapper找不到selectOne

请教大佬们 mapper接口里方法命名的问题。

我有个Mapper 接口,里面有两个方法,都是返回一个对象,但是返回的参数不同,怎么命名呢。比如A页面只需要展示id,age这两个字段,B页面只需要展示id,name,sex这三个字段。接口里的方法怎么命名。难道要写个返回全部字段的方法,然后在各自的Service层过滤掉不需要的字段?<br> 第一方法 SELECT id,age FROM user;<br> 第二方法 SELECT id,name,sex FROM user; 在mapper里方法怎么命名。请大佬举个栗子,谢谢了

ArrayList源码分析(入门篇)

ArrayList源码分析 前言: 写这篇博客的主要原因是,在我上一次参加千牵科技Java实习生面试时,有被面试官问到ArrayList为什么查找的速度较快,插入和删除的速度较慢?当时我回答得不好,很大的一部分原因是因为我没有阅读过ArrayList源码,虽然最后收到Offer了,但我拒绝了,打算寒假学得再深入些再广泛些,下学期开学后再去投递其他更好的公司。为了更加深入理解ArrayList,也为

我以为我学懂了数据结构,直到看了这个导图才发现,我错了

数据结构与算法思维导图

String s = new String(" a ") 到底产生几个对象?

老生常谈的一个梗,到2020了还在争论,你们一天天的,哎哎哎,我不是针对你一个,我是说在座的各位都是人才! 上图红色的这3个箭头,对于通过new产生一个字符串(”宜春”)时,会先去常量池中查找是否已经有了”宜春”对象,如果没有则在常量池中创建一个此字符串对象,然后堆中再创建一个常量池中此”宜春”对象的拷贝对象。 也就是说准确答案是产生了一个或两个对象,如果常量池中原来没有 ”宜春” ,就是两个。...

上班一个月,后悔当初着急入职的选择了

最近有个老铁,告诉我说,上班一个月,后悔当初着急入职现在公司了。他之前在美图做手机研发,今年美图那边今年也有一波组织优化调整,他是其中一个,在协商离职后,当时捉急找工作上班,因为有房贷供着,不能没有收入来源。所以匆忙选了一家公司,实际上是一个大型外包公司,主要派遣给其他手机厂商做外包项目。**当时承诺待遇还不错,所以就立马入职去上班了。但是后面入职后,发现薪酬待遇这块并不是HR所说那样,那个HR自...

玩转springboot启动banner定义所得

最近接手了一个springboot项目,不是不熟悉这个框架,启动时打印的信息吸引了我。 这不是我熟悉的常用springboot的打印信息啊,我打开自己的项目: 还真是的,不用默认的感觉也挺高大上的。一时兴起,就去研究了一下源代码,还正是有些收获,稍后我会总结一下。正常情况下做为一个老程序员,是不会对这种小儿科感兴趣的,不就是一个控制台打印嘛。哈哈! 于是出于最初的好奇,研究了项目的源代码。看到

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

《经典算法案例》01-08:如何使用质数设计扫雷(Minesweeper)游戏

我们都玩过Windows操作系统中的经典游戏扫雷(Minesweeper),如果把质数当作一颗雷,那么,表格中红色的数字哪些是雷(质数)?您能找出多少个呢?文中用列表的方式罗列了10000以内的自然数、质数(素数),6的倍数等,方便大家观察质数的分布规律及特性,以便对算法求解有指导意义。另外,判断质数是初学算法,理解算法重要性的一个非常好的案例。
