关于springmvc+mybatis 注入问题

service:

 package com.yhq.service.biz;

import com.yhq.service.po.User;

public interface UserBiz {
    void insert(User u);
}

impl:

 package com.yhq.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.yhq.service.api.UserMapper;
import com.yhq.service.biz.UserBiz;

    private UserMapper userMapper;

    public void insert(User u) {
        // TODO Auto-generated method stub
        userMapper.insert(u);

异常信息显示UserMapper 这个类型的属性注入失败,检查写这个UserMapper 类的定义,是否所有属性都提供了getter和setter,以及无参数构造函数。

用Spring SpringMVC MyBatis 实现用户注册登录并保存验证。 求代码 谢大神
注册,将新用户输入的信息提交并进行验证,验证可采用验证框架也可采用validate,验证失败返回注册页面显示错误信息,验证成功后保存用户数据。 登陆,验证,失败后返回登陆页面显示错误信息,验证成功后保存用户信息至session。 登陆成功后,将所有用户数据展示给用户,列出用户详细信息,并分页。用拦截器判断,如果没有登陆的话返回登陆页面并提示用户没有登陆 1、Ioc注入全部采用Spring注解型注入。 2、使用mybatis持久层完成对数据库的操作 3、显示request对象数据使用EL表达式 4、使用Ajax框架Jquery完成异步提交 5、页面表单提交使用SpringMVC的rest传值方式。 6、工程结构com.zxkj.common.model、com.zxkj.common.dao、com.zxkj.common.dao.impl、com.zxkj.common.service、com.zxkj.common.service.impl、com.zxkj.common.controller 用户信息分两表保存 控件以及页面控制使用El表达式和标准标签库 ajax采用Jquery完成异步提交 必要时,使用easyui美化渲染页面。 数据库使用SqlServer2000以上版本

大神来看看这个是什么意思,给解释下
首先说明下 我用的是springMVC mybatis 很多时候我们 在操作数据库的时候 LoginController 直接使用@Autowired 直接可以注入。 那么 在其他类中 需要通过以下方法才可以获得对象 。如果直接使用 @Autowired直接空 指针。 我对以下的理解是这样,大神勿喷。LoginController通过注解可以获得对象,但是如果在其他类中,那么就是在容器外,需要加载上下文 告诉容器你要操作的class然后获得操作的容器BeanID 才可以 对这个类进行使用。不知是否理解的对,给纠正一下,并告诉小弟 是否有其他方法在容器外 可以不通过注解 获得? ApplicationContext atx=new ClassPathXmlApplicationContext("classpath:com/hoomsun/mybatis/config/applicationContext.xml"); CostMapperDao dao=atx.getBean(CostMapperDao.class);
求教一下各位大牛Spring,Mybatis整合注解出现注入失败问题?

MavenWeb项目使用mybatis的分页查询插件,在项目部署时出现错误
MavenWeb项目使用mybatis的分页查询插件,在项目部署时出现错误,在程序中 运行可以查询出来,但是我只要用tomcat启动项目就报错,把mybatis的分页插件 配置注掉后就又可以部署成功,有没有大佬知道是什么情况!?? 下面是报错信息 ``` D:\apache-tomcat-9.0.19\bin\catalina.bat run [2019-06-22 06:33:48,732] Artifact SSM整合:war exploded: Waiting for server connection to start artifact deployment...

SSM Dubbo 集成 Shiro 自定义Realm 注入 SysUserMapper 失败
先说下大概框架 SpringMVC Spring Mybatis 集成Dubbo,现在引入 shiro 服务端 配置 spring-mybatis.xml spring-service.xml 文件 消费端 配置 spring-mvc.xml 文件 当前 shiro.xml 配置文件 配置在了 消费端 。(服务端 ,消费端 都配置过 ,配置在服务端 ,页面拦截失效)。 spring-service.xml : ``` <context:component-scan base-package="com.artmall.manager.service"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` spring-mvc.xml : ``` <!-- 扫描带注解的包 --> <context:component-scan base-package="com.artmall.manager"> <context:include-filter type="aspectj" expression="com.artmall.manager.common.aspect"/> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` # 出现问题: 自定义 Realm 的时候 引入 SysUserMapper , 服务端启动的时候 报错,Error creating bean with name 'userRealm': Could not autowire field :SysUserMapper。也就是说 SysUserMapper 注入是失败的 。 ** 理解**: shiro的自定义realm的认证阶段属于filter,当时的spring bean还没有读取进来。 见上配置文件 **服务端** 在启动的时候就已经 扫描 service了。 疑问的是 消费端 再启动的时候为什么 还会报这样的错。不知道是我理解的还不够到位还是什么 配置上有问题 希望有知道的朋友多多指点下 非常感谢。
SSB 框架注入mapper遇到的问题
(小白提问,有什么不对的指出来)上周遇到了一个问题,项目有点久,没有springMVC的框架,想集成进去,但是后来发现注解无法将mapper注入到容器![项目结构](https://img-ask.csdn.net/upload/201803/26/1522057054_563241.png) mapper就只是一个interface 的.java文件,然后在另一个包下面有映射的.xml文件 在此之前,我单独的将service注入到controller没问题,返回一个了Map在WEB上可以看到,但是我在service层用注解@不论是Res..还是Auto,,都会报错,我确认过配置扫描包路径都没有问题,迫不得已用了原先的配置文件方法,发现又可以了 上两个对比图 ![图片说明](https://img-ask.csdn.net/upload/201803/26/1522057455_824599.png),![图片说明](https://img-ask.csdn.net/upload/201803/26/1522057471_877945.png),![图片说明](https://img-ask.csdn.net/upload/201803/26/1522057695_920679.png),新增配置文件如图![图片说明](https://img-ask.csdn.net/upload/201803/26/1522057748_550821.png),这是mapper现在有两个问题,为什么我配置文件可以,用注解却不行, 第二个,为什么我要用TestMapper mapper = ApplicationContextFactory.getBean("testMapper", TestMapper.class);才能取到mapper,直接用还是空?

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
