Spring+SpringMVC+Mybatis集成一个小的案例

以前也在网上找了一些关于spring、springmvc、mybatis的项目框架，现在自己写了一个简单的员工管理
一、主要步骤
1.用idea创建一个maven工程
2.准备相关的jar包，不需要手动导入，maven自动创建
3.创建相关的包
4.创建相关的DAO层，Service层，Controller层
5.配置database.properties、Configuration.xml、applicationContext.xml等文件
6.配置web.xml文件
7.编写视图（jsp）
注：数据库自己建立即可
二、详细代码如下
         pom.xml

1.database.properties文件
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/emp?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123

2.配置applicationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
<property name="mapperInterface" value="com.iflytek.inter.EmpOperation"/>
</bean>
</beans>

3.配置Configuration.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPEconfigurationPUBLIC"-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

<typeAliases>

<!--通过package, 可以直接指定package的名字， mybatis会自动扫描你指定包下面的javabean,
并且默认设置一个别名，默认的名字为： javabean 的首字母小写的非限定类名来作为它的别名。
也可在javabean 加上注解@Alias 来自定义别名， 例如： @Alias(user) -->

<typeAlias type="com.iflytek.entity.Employee" alias="Employee"/>

</typeAliases>

</configuration>

4.Employee.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPEmapperPUBLIC"-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.iflytek.inter.EmpOperation">

<!--在mybatis中，映射文件中的namespace是用于绑定Dao接口的，即面向接口编程。

当你的namespace绑定接口后，你可以不用写接口实现类，mybatis会通过该绑定自动
帮你找到对应要执行的SQL语句-->

<!---sql代码 1.根据员工ID查看员工信息--> 

<select id="selectEmpById" parameterType="int" resultType="Employee"> 

select * FROMemployee WHERE empId = #{empId} 

</select> 

<!--查询数据，返回list-->  

<resultMap id="resultEmployeeList" type="Employee"> 

 <id column="empId" property="empId"/> 

<result column="empName" property="empName"/> 

<result column="empAge" property="empAge"/>  

<result column="empTelD" property="empTel"/> 

<result column="empAddress" property="empAddress"/>  

</resultMap> 

<select id="selectEmp" resultMap="resultEmployeeList"> 

SELECT* FROM employee ; 

</select> 

<insert id="addEmp" parameterType="Employee" useGeneratedKeys="true" keyProperty="empId">INSERT INTO employee(empName,empAge,empTel,empAddress)  

VALUES (#{empName},#{empAge},#{empTel},#{empAddress})  

</insert> 

<update id="updateEmp" parameterType="Employee"> 

UPDATE employee SETempName = #{empName},empAge = #{empAge},empTel = #{empTel},empAddress = #{empAddress}WHERE empId = #{empId}  

</update> 

<delete id="deleteEmp" parameterType="int">  

DELETE FROM employee WHERE empId = #{empId}  

</delete>

</mapper>

</beans>

7. model(entity)文件

package com.iflytek.entity;

import java.io.Serializable;

public class Employee implements Serializable {

 private int empId; //员工ID

 private String empName;//员工姓名

 private String empAge;//员工年龄

 private String empTel;//员工电话号码

 private String empAddress;//员工地址

 public Employee() { }

 public Employee(int empId, String empName, String empAge, String empTel, String empAddress) {

empId = empId;

this.empName = empName;

this.empAge = empAge;

this.empTel = empTel;

this.empAddress = empAddress; }

 public String getEmpTel() {

return empTel; }

 public void setEmpTel(String empTel) {

this.empTel = empTel; }

 public int getEmpId() {

return empId;

 }

 public void setEmpId(int empId) {

this.empId = empId;

 }

 public String getEmpName() {

return empName; }

 public void setEmpName(String empName) {

this.empName = empName; }

 public String getEmpAge() {

return empAge; }

 public void setEmpAge(String empAge) {

this.empAge = empAge; }

 public String getEmpAddress() {

return empAddress; }

 public void setEmpAddress(String empAddress) {

this.empAddress = empAddress; }

 @Override

 public String toString() {

return "Employee{" +

 "empId=" + empId +

 ", empName='" + empName + '\'' +

 ", empAge='" + empAge + '\'' + ", empTel='" + empTel + '\'' + ", empAddress='" + empAddress + '\'' + '}'; }

}

8.inter代码如下

package com.iflytek.inter;

import com.iflytek.entity.Employee；

import java.util.List;

public interface EmpOperation {

 public Employee selectEmpById(int empId);//根据ID查看信息

 public List<Employee> selectEmp();//查看员工信息

 public void addEmp(Employee employee);//新增员工信息

 public void updateEmp(Employee employee);//修改员工信息

 public void deleteEmp(int empId);//删除员工信息

}

9.controller代码如下

package com.iflytek.controller;

import com.iflytek.entity.Employee;
import com.iflytek.inter.EmpOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.support.AbstractMultipartHttpServletRequest;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

@Controller
public class EmpController {
@Autowired
EmpOperation empOperation;
@RequestMapping(value="login")
public ModelAndView listAllEmp(HttpServletRequest request, HttpServletResponse response) throws IOException {
ModelAndView mv = null;
response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
String accout = request.getParameter("account");
String password = request.getParameter("password");
if(accout.equals("admin") && password.equals("123")){
request.getSession().setAttribute("account",accout);
List<Employee> emp =empOperation.selectEmp();
for (Employee e:emp){
System.out.println(e.toString());
}
mv = new ModelAndView("list.jsp");
mv.addObject("emp",emp);
}else{
PrintWriter pw = response.getWriter();
pw.println("<script type='text/javascript'>");
pw.println("alert('用户或密码不正确');");
pw.println("window.location.href='index.jsp';");
pw.println("</script>");
}
return mv;
}
}

10.test代码 这里没有使用junit测试，只用了main方法

package com.iflytek.test;

import com.iflytek.entity.Employee;
import com.iflytek.inter.EmpOperation;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.util.List;

public class Test {
private static ApplicationContext ctx;
static{
ctx = new ClassPathXmlApplicationContext("/spring/applicationContext.xml");
}

public static void main(String[] args) {
EmpOperation mapper = (EmpOperation)ctx.getBean("EmpMapper");
List<Employee>emp = mapper.selectEmp();
for(Employee emps:emp){
System.out.println(emps.toString());
}
System.out.println("成功");
}
}

11.index.jsp如下

<body>
<center>
<font color="red">员工入口</font><hr/>
<form action="login" method="post">
<table>
<tr>
<td>用户账号:</td>
<td><input type="text" name="account" value=""/></td>
</tr>
<tr>
<td>用户密码:</td>
<td><input type="password" name="password" value=""/></td>
</tr>
<tr>
<td colspan="2">
<input type="submit" value="登录" onclick="return check(this.form)";/>   
<input type="reset" value="重置"/>
</td>
</tr>

</table>
</form>
</center>
</body>

12.list.jsp代码如下

<body>
<center>
<h3>欢迎进入员工管理系统</h3>
<table border="1"bgcolor="#E5E5E5" bordercolor="#f0f0f0" width="480" height="20px" >
<tr>
<td width="80">员工ID</td>
<td>员工姓名</td>
<td width="100">员工年龄</td>
<td width="100">联系方式</td>
<td width="100">地址</td>

</tr>
</table >
<table style="border-collapse: collapse";border="1" bordercolor="black" width="480" height="40">
<c:forEach items="${emp}" var="e">
<tr>
<td width="80">${e.empId}</td>
<td width="100">${e.empName}</td>
<td width="100">${e.empAge}</td>
<td width="100">${e.empTel}</td>
<td width="100">${e.empAddress}</td>
</tr>
</c:forEach>
</table>
</center>
</body>

13.项目的整体结构如下
