Eclipse编写SSM(增删改查)框架项目

首先创建动态web项目：

接下来写代码：

web.xml代码：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!--过滤器-->

	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>
        

springmvc-servlet.xml代码：

实体类代码：

package com.accp.entity;

import java.util.Date;

public class edoc_entry {
	private Integer id; //文档编号
	private Integer categoryId; //分类编号
	private String title; //文档名称
	private String summary; //文档摘要
	private String uploadUser; //上传人
	private Date createDate; //上传时间
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public Integer getCategoryId() {
		return categoryId;
	}
	public void setCategoryId(Integer categoryId) {

	}
	public String getTitle() {

	}
	public void setTitle(String title) {

	}
	public Date getCreateDate() {

	}
	public void setCreateDate(Date createDate) {

	}
	
}

package com.accp.entity;

public class edoc_category {
	private Integer id; //分类编号
	private String name; //分类名称
	public Integer getId() {

	}
	public void setId(Integer id) {

	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	

}

Dao层代码：

package com.accp.dao;

import java.util.List;

import com.accp.entity.edoc_category;

public interface edoc_categoryDao {
	List<edoc_category> seeCategoryList(); //查询分类
	
}

package com.accp.dao;

import java.util.List;

import org.apache.ibatis.annotations.Param;

import com.accp.entity.edoc_entry;

public interface edoc_entryDao {
	List<edoc_entry> seeEntryList(@Param("categoryId")Integer categoryId); //查询列表
	
	int insertEntry(edoc_entry entry); //添加方法
	
	int delEntry(edoc_entry entry); //删除方法
	
	int updEntry(edoc_entry entry); //修改方法
	
	edoc_entry updByIdEntry(edoc_entry entry); //修改页面传值
}

mapping映射文件代码：

<?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.accp.dao.edoc_entryDao">

	<select id="seeEntryList" resultType="edoc_entry">
		select * from edoc_entry
		<where>
			<if test="categoryId>0">
				categoryId = #{categoryId}
			</if>
		</where>
	</select>

	<insert id="insertEntry">
		insert into edoc_entry
		values(default,#{categoryId},#{title},#{summary},#{uploadUser},#{createDate})
	</insert>

	<delete id="delEntry">

	</delete>

	<update id="updEntry">

		<trim prefix="set" suffixOverrides="," suffix="where id = #{id}">

	</update>

	<select id="updByIdEntry" resultType="edoc_entry">
		select * from edoc_entry

	</select>
</mapper>

<?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.accp.dao.edoc_categoryDao">
    
	<select id="seeCategoryList" resultType="edoc_category">
		select * from edoc_category
	</select>

</mapper>

biz层代码：

package com.accp.biz;

import java.util.List;

import com.accp.entity.edoc_category;

public interface edoc_categoryBiz {
	List<edoc_category> seeCategoryList(); //查询分类
}

package com.accp.biz;

import java.util.List;

import org.apache.ibatis.annotations.Param;

import com.accp.entity.edoc_entry;

public interface edoc_entryBiz {
List<edoc_entry> seeEntryList(@Param("categoryId")Integer categoryId); //查询列表
	
	int insertEntry(edoc_entry entry); //添加方法
	
	int delEntry(edoc_entry entry); //删除方法
	
	int updEntry(edoc_entry entry); //修改方法
	
	edoc_entry updByIdEntry(edoc_entry entry); //修改页面传值
}

biz.impl实现类代码：

package com.accp.biz.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.accp.biz.edoc_categoryBiz;
import com.accp.dao.edoc_categoryDao;
import com.accp.entity.edoc_category;

@Service
public class edoc_categoryBizImpl implements edoc_categoryBiz {
	
	@Resource
	private edoc_categoryDao categoryDao;

	@Override
	public List<edoc_category> seeCategoryList() {
		// TODO Auto-generated method stub
		return categoryDao.seeCategoryList();
	}

}

package com.accp.biz.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.accp.biz.edoc_entryBiz;
import com.accp.dao.edoc_entryDao;
import com.accp.entity.edoc_entry;

@Service
public class edoc_entryBizImpl implements edoc_entryBiz {
	
	@Resource
	private edoc_entryDao entryDao;

	@Override
	public List<edoc_entry> seeEntryList(Integer categoryId) {
		// TODO Auto-generated method stub
		return entryDao.seeEntryList(categoryId);
	}

	@Override
	public int insertEntry(edoc_entry entry) {
		// TODO Auto-generated method stub
		return entryDao.insertEntry(entry);
	}

	@Override
	public int delEntry(edoc_entry entry) {
		// TODO Auto-generated method stub
		return entryDao.delEntry(entry);
	}

	@Override
	public int updEntry(edoc_entry entry) {
		// TODO Auto-generated method stub
		return entryDao.updEntry(entry);
	}

	@Override
	public edoc_entry updByIdEntry(edoc_entry entry) {
		// TODO Auto-generated method stub
		return entryDao.updByIdEntry(entry);
	}

	
}

control控制层代码：

package com.accp.control;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import com.accp.biz.edoc_categoryBiz;
import com.accp.biz.edoc_entryBiz;
import com.accp.entity.edoc_category;
import com.accp.entity.edoc_entry;

@Controller
public class edoc_entryControl {
	
	@Resource
	private edoc_entryBiz entrybiz;
	@Resource
	private edoc_categoryBiz categoryBiz;
	
	@RequestMapping("/showcategory")
	public String showcategory(@RequestParam(required=false,defaultValue="0")Integer categoryId,Model m) {
		m.addAttribute("catList", categoryBiz.seeCategoryList());
		m.addAttribute("entryList",entrybiz.seeEntryList(categoryId));
		return "index";
	}
	
	@RequestMapping("/addentry")
	public String addentry(edoc_entry e) {
		entrybiz.insertEntry(e);
		return "redirect:/showcategory";
	}
	
	@RequestMapping("/deleteentry")
	public String deleteentry(edoc_entry e) {
		entrybiz.delEntry(e);
		return "redirect:/showcategory";
	}
	
	@RequestMapping("/updateentry")
	public String updateentry(edoc_entry e) {
		entrybiz.updEntry(e);
		return "redirect:/showcategory";
	}
	
	@RequestMapping("/updateByIdentry")
	public String updateByIdentry(edoc_entry e,Model m) {
		m.addAttribute("entryMsg",entrybiz.updByIdEntry(e));
		return "update";
	}
	

}
