Spring+SpringMVC+ Mybatis(Spring Tools Suites 3) 简单项目
作者：互联网
STS 3
tomcat 9.0,
JDK 8
一、项目结构
二、项目依赖
三、创建项目前生成web.xml文件
项目右键--》Java EE Tools-->Generate Deployment Descriptor Stub-->生成web.xml文件
四、创建项目代码
1.创建实体类
例如：Dept.java
package com.dxj.entity;
import java.sql.Timestamp;
import org.apache.ibatis.type.Alias;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
/**
* 部门 Dept
* @author Administrator
*
*/
@Alias("Dept")
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Dept {
private Integer id;
private String name;
private String loc;
private Timestamp date;
private String person;
}
2.创建数据持久层Mapper
例如：DeptMapper.java
package com.dxj.mapper
import java.util.List;
import org.apache.ibatis.annotations.Param;
import com.dxj.entity.Dept;
/**
* 部门 测试方法
* @author Administrator
*
*/
public interface DeptMapper {
void save(Dept dept);
List<Dept> findAll();
void update(@Param("upd")Dept dept);
void del(Integer id);
}
3.创建服务层
例如：IDeptService.java
package com.dxj.service;
import java.util.List;
import org.apache.ibatis.annotations.Param;
import com.dxj.entity.Dept;
/**
* 部门 服务接口
* @author Administrator
*
*/
public interface IDeptService {
void save(Dept dept);
List<Dept> findAll();
void update(@Param("upd")Dept dept);
void del(Integer id);
}
IDeptServiceImpl.java
package com.dxj.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import com.dxj.entity.Dept;
import com.dxj.mapper.DeptMapper;
import com.dxj.service.IDeptService;
/**
* 部门 服务实现
* @author Administrator
*
*/
@Service("ids")
@Transactional(propagation = Propagation.SUPPORTS)
public class DeptServiceImpl implements IDeptService {
@Autowired
private DeptMapper iDeptMapper;
@Override
public List<Dept> findAll() {
return iDeptMapper.findAll();
}
@Override
public void save(Dept dept) {
iDeptMapper.save(dept);
}
@Override
public void update(Dept dept) {
iDeptMapper.update(dept);
}
@Override
public void del(Integer id) {
iDeptMapper.del(id);
}
}
4.创建前后端交互层Controller
例如：DeptController.java
package com.dxj.controllers;
import java.sql.Timestamp;
import java.util.Date;
import java.util.List;
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.ResponseBody;
import com.dxj.entity.Dept;
import com.dxj.service.IDeptService;
/**
* 部门
* @author Administrator
*
*/
@Controller
public class DeptController {
@Autowired
private IDeptService ids;
@RequestMapping("/findAll.action")
@ResponseBody
public List<Dept> findAll(){
return ids.findAll();
}
@RequestMapping("/save.action")
@ResponseBody
public String save(Dept dept) {
ids.save(new Dept(null, "dxj",
"308", new Timestamp(new Date().getTime()), "summer"));
return "添加成功";
}
@RequestMapping("/update.action")
@ResponseBody
public String update(Dept dept) {
ids.update(new Dept(2, "hf", null, null, null));
return "修改成功";
}
@RequestMapping("/del.action")
@ResponseBody
public String del(Integer id) {
ids.del(4);
return "删除成功";
}
}
五、配置文件
