eclipse ssm 环境搭建

1.创建数据库:

-- ----------------------------
-- Table structure for `department`
-- ----------------------------

DROP TABLE IF EXISTS `department`;
CREATE TABLE `department` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '唯一id',
  `name` varchar(25) DEFAULT NULL COMMENT '年龄',
  `is_ok` int(11) DEFAULT '1' COMMENT '是否有效',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of department
-- ----------------------------
INSERT INTO `department` VALUES ('1', '研发部', '1');
INSERT INTO `department` VALUES ('2', '销售部', '1');


-- ----------------------------
-- Table structure for `employee`
-- ----------------------------
DROP TABLE IF EXISTS `employee`;
CREATE TABLE `employee` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '唯一id',
  `name` varchar(50) DEFAULT NULL COMMENT '姓名',
  `age` int(11) DEFAULT NULL COMMENT '年龄',
  `department_id` int(11) DEFAULT NULL COMMENT '部门id',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of employee
-- ----------------------------
INSERT INTO `employee` VALUES ('1', '张三', '20', '1');
INSERT INTO `employee` VALUES ('2', '李四', '20', '2');

2.导入基础jar包

3.创建项目

右键New -- Dynamic Web Project 

4.创建项目目录结构

5.创建实体类

Employee.java

public class Employee {
private Integer id;
private String name;
private Integer age;
private Integer department_id;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Integer getDepartment_id() {
return department_id;
}
public void setDepartment_id(Integer department_id) {
this.department_id = department_id;
}

public Employee(Integer id, String name, Integer age, Integer department_id) {
super();
this.id = id;
this.name = name;
this.age = age;
this.department_id = department_id;
}
public Employee() {
super();
}

@Override
public String toString() {
return "Employee [id=" + id + ", name=" + name + ", age=" + age + ", department_id=" + department_id + "]";
}

}

6.创建mapper接口以及mapper.xml文件

EmployeeMapper:

import org.springframework.stereotype.Component;


import com.ssm.po.Employee;


@Component("employeeMapper")
public interface EmployeeMapper {
Employee getEmpById(int id);
}

EmployeeMapper:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.ssm.mapper.EmployeeMapper" >
<select id="getEmpById" parameterType="int" resultType="com.ssm.po.Employee">
        select * from employee where id=#{id}
    </select>
</mapper>

7.创建service

EmployeeService:

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

import com.ssm.mapper.EmployeeMapper;
import com.ssm.po.Employee;

@Service
public class EmployeeService {
@Autowired
EmployeeMapper employeeMapper;


public Employee getEmp(){
return employeeMapper.getEmpById(1);
}
}

8.创建control控制器

EmployeeControl:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.Model;

import com.ssm.service.EmployeeService;
@Controller
@RequestMapping("/mvc")
public class EmployeeControl {

@Autowired
EmployeeService service;

@RequestMapping(value="/emp",method={RequestMethod.GET,RequestMethod.POST})
public String test(Model model){
model.addAttribute("emp", service.getEmp());
return "success";
}
}

9.创建配置文件

①创建数据库配置文件(db.properties)

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/ssm?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=mysql

②spring配置文件(applicationContext.xml)

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

</beans>    

③ springmvc配置文件(springmvc.xml)

<?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"

10.创建jsp

success.jsp:

<%@ 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 PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
${emp.name }
</body>
</html>
