说明要加载的注解的类型

操作数据库

2.调用

UserMapper.javaimport java.util.List;import com.offcn.bean.Student;public interface UserMapper { public List<Student> selectStudent(); public void insertStudent(Student student); public void deleteBySid(Integer sid); public Student selectBySid(Integer sid); public void updateStudent(Student student);}

1.请求

web层(springMvc)Controller.java

log4j配置日志文件

update.jsp(更新页面)<%@ page language=\"java\" contentType=\"text/html; charset=UTF-8\" pageEncoding=\"UTF-8\"%><%@ taglib prefix=\"c\" uri=\"http://java.sun.com/jsp/jstl/core\" %><!DOCTYPE html><html><head><meta charset=\"UTF-8\"><title>Insert title here</title></head><body><form action=\"${pageContext.request.contextPath }/student/insert\" method=\"post\"> <c:if test=\"${!empty stutent }\"> <input type=\"hidden\" name=\"_method\" value=\"PUT\"> <input type=\"hidden\" name=\"sid\" value=\"${student.sid }\"> </c:if> <table cellpadding=\"10px\"> <caption>个人信息添加</caption> <tr><td>姓名:</td><td><input type=\"text\" name=\"sname\" value=\"${student.sname }\"></td></tr> <tr><td>密码:</td><td><input type=\"text\" name=\"pwd\" value=\"${student.pwd }\"></td> </tr> <tr> <td>性别:</td> <td> <input <c:if test=\"${student.gender == 1 }\">checked</c:if> type=\"radio\" name=\"gender\" value=\"1\">男 <input <c:if test=\"${student.gender == 0 }\">checked</c:if> type=\"radio\" name=\"gender\" value=\"0\">女 </td> </tr> <tr> <td>爱好:</td> <td> <input <c:if test=\"${student.hobby.contains('唱歌') }\">checked</c:if> type=\"checkbox\" name=\"hobby\" value=\"唱歌\">唱歌 <input <c:if test=\"${student.hobby.contains('跳舞') }\">checked</c:if> type=\"checkbox\" name=\"hobby\" value=\"跳舞\">跳舞 <input <c:if test=\"${student.hobby.contains('RAP') }\">checked</c:if> type=\"checkbox\" name=\"hobby\" value=\"RAP\">RAP <input <c:if test=\"${student.hobby.contains('篮球') }\">checked</c:if> type=\"checkbox\" name=\"hobby\" value=\"篮球\">篮球 </td> </tr> <tr> <td>简历:</td> <td> <textarea name=\"mark\" rows=\"\" cols=\"\">${student.mark }</textarea> </td> </tr> <tr> <td colspan=\"2\" align=\"center\"> <input type=\"submit\" value=\"提交\"> </td> </tr> </table></form></body></html>

指定扫描的包

请求dao层

mybatis-config.xml文件(这是普通的xml文件但是头部需要独立复制一下)<?xml version=\"1.0\" encoding=\"UTF-8\" ?><!DOCTYPE configuration PUBLIC \"-//mybatis.org//DTD Config 3.0//EN\" \"http://mybatis.org/dtd/mybatis-3-config.dtd\"><configuration> <settings>  <setting name=\"lazyLoadingEnabled\" value=\"true\"/> <setting name=\"aggressiveLazyLoading\" value=\"false\"/> </settings></configuration>

mybatis-config.xml1.开启懒加载模式作用:懒加载其实就是延时加载，即当对象需要用到的时候再去加载。

properties文件

beans.xml1.扫描包作用:加载加了注解的类对象2.加载properties文件3.配置数据源作用:将properties文件中的信息获取4.配置数据源事务管理器作用:配置数据源5.开启基于注解的事务支持6.加载mybatis全局配置文件7.扫描Mapper接口作用:连接dao层的

不要将包中带注解的全部加载进容器
