部门管理
基于SSM框架的开发过程及体会
一.SpringMVC和Mybatis整合
1.所需jar包
1.1 Spring（包括SpringMVC）所需jar包
1.2 MyBatis所需jar包
1.3 mybatis-spring整合包
1.4数据库驱动包
1.5第三方数据库连接池
2.整合Dao层
2.1配置
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ehr
jdbc.username=root
jdbc.password=2036292.2配置
#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = D\:logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
#输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n2.3配置mybatis全局配置文件
2.4配置spring配置文件
3.整合Service层
3.1配置
3.2配置
4.整合表现层
4.1配置处理器映射器、处理器适配器和视图解析器
4.2配置前端控制器

二.具体代码编写流程（以部门管理为例）
1.Dao层代码的编写，生成pojo类及mapper
1.1
package com.neuedu.pojo;
public class Department {
private Integer dp_id;
private String dp_name;
private Integer dp_tele;
private String dp_fd;
public Department() {
super();
}
public Department(Integer dp_id, String dp_name, Integer dp_tele, String dp_fd) {
super();
this.dp_id = dp_id;
this.dp_name = dp_name;
this.dp_tele = dp_tele;
this.dp_fd = dp_fd;
}
public Integer getDp_id() {
return dp_id;
}
public void setDp_id(Integer dp_id) {
this.dp_id = dp_id;
}
public String getDp_name() {
return dp_name;
}
public void setDp_name(String dp_name) {
this.dp_name = dp_name;
}
public Integer getDp_tele() {
return dp_tele;
}
public void setDp_tele(Integer dp_tele) {
this.dp_tele = dp_tele;
}
public String getDp_fd() {
return dp_fd;
}
public void setDp_fd(String dp_fd) {
this.dp_fd = dp_fd;
}
}1.2
1.2.1 
package com.neuedu.mapper;
import com.neuedu.pojo.Department;
import com.neuedu.pojo.Post;
import com.neuedu.pojo.Staff;
public interface UserMapper {
//部门管理
public Department findDepartmentListByIdAndName(Integer dp_id,String dp_name)throws Exception;
public int insertDepartment(Department department)throws Exception;
public int updateDepartment(Department department)throws Exception;
public Department findDepartmentListById(Integer dp_id)throws Exception;
public int deleteDepartment(Integer dp_id)throws Exception;
}1.2.2 
INSERT INTO department(dp_id,dp_name,dp_tele,dp_fd) VALUES(#{dp_id},#{dp_name},#{dp_tele},#{dp_fd})
UPDATE department
SET dp_name=#{dp_name},dp_tele=#{dp_tele},dp_fd=#{dp_fd}
WHERE dp_id=#{dp_id}
DELETE FROM department
WHERE dp_id=#{dp_id}
2.Service层代码的编写
2.1
package com.neuedu.service;
import com.neuedu.pojo.Department;
public interface UserService {
//部门管理
public Department findDepartmentListByIdAndName(Integer dp_id,String dp_name)throws Exception;
public int insertDepartment(Department department)throws Exception;
public int updateDepartment(Department department)throws Exception;
public Department findDepartmentListById(Integer dp_id)throws Exception;
public int deleteDepartment(Integer dp_id)throws Exception;
}2.2
package com.neuedu.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.neuedu.mapper.UserMapper;
import com.neuedu.pojo.Department;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public Department findDepartmentListByIdAndName(Integer dp_id,String dp_name)throws Exception{
return userMapper.findDepartmentListByIdAndName(dp_id,dp_name);
}
public int insertDepartment(Department department)throws Exception{
return userMapper.insertDepartment(department);
}
public int updateDepartment(Department department)throws Exception{
return userMapper.updateDepartment(department);
}
@Override
public Department findDepartmentListById(Integer dp_id) throws Exception {
// TODO Auto-generated method stub
return userMapper.findDepartmentListById(dp_id);
}
public int deleteDepartment(Integer dp_id)throws Exception{
return userMapper.deleteDepartment(dp_id);
}
}3.Web层代码的编写 
package com.neuedu.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.neuedu.pojo.Department;
import com.neuedu.service.UserService;
@Controller
@RequestMapping(value="/user")
public class controller {
@Autowired
private UserService userService;
//查询Department
@RequestMapping(value="/findDepartmentListByIdAndName")
public ModelAndView findDepartmentListByIdAndName(Integer dp_id,String dp_name)throws Exception {
Department department = userService.findDepartmentListByIdAndName(dp_id, dp_name);
ModelAndView mv = new ModelAndView();
mv.addObject("department",department);
mv.setViewName("bumenguanli/save2_index2");
return mv;
}
@RequestMapping(value="/findDepartmentListById")
public ModelAndView findDepartmentListById(Integer dp_id)throws Exception {
Department department = userService.findDepartmentListById(dp_id);
ModelAndView mv = new ModelAndView();
mv.addObject("department",department);
mv.setViewName("bumenguanli/save2_index2");
return mv;
}
//插入Department
@RequestMapping(value="/addDepartment")
public ModelAndView addDepartment(Department department)throws Exception{
userService.insertDepartment(department);
ModelAndView mv = new ModelAndView();
mv.setViewName("save2_index1");
return mv;
}
//更新Department
@RequestMapping(value="/toupdateDepartment")
public ModelAndView toupdateDepartment(Integer dp_id)throws Exception{
Department department = userService.findDepartmentListById(dp_id);
ModelAndView mv = new ModelAndView();
mv.addObject("department",department);
mv.setViewName("bumenguanli/alter_index");
return mv;
}
@RequestMapping(value="/updateDepartment")
public ModelAndView updateDepartment(Department department)throws Exception{
int deptid = userService.updateDepartment(department);
ModelAndView mv = new ModelAndView();
mv.setViewName("bumenguanli/save2_index1");
return mv;
}
//删除Department
@RequestMapping(value="/deleteDepartment")
public ModelAndView deleteDepartment(Integer dp_id)throws Exception{
int count = userService.deleteDepartment(dp_id);
ModelAndView mv = new ModelAndView();
mv.setViewName("bumenguanli/save2_index1");
return mv;
}
}4.前台jsp页面代码的编写

save2_index1
三.开发体会
通过实际项目的开发，我对ssm框架有了更深入的理解，比如说对象之间的依赖关系由spring控制，减小了耦合，简化了开发；再比如说mybatis支持动态的sql，数据库的操作采用xml文件配置，解除了sql和代码的耦合等。
随着由浅入深的学习，从对ssm框架一无所知到有所涉猎，我能体会到该框架的优势，以后也会继续学习。
