一个controller配置例子：



package project.controller.admin;

import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Date;
import project.controller.MyController;
import project.model.Blog;
import project.service.BlogService;
import project.controller.MyController;

/**

*/
/**
 * @author https://www.javawebxx.com    javaweb学习网
 * 备注：>ssm框架ssh框架springmvc框架搭建下载javaweb学习网
 */
@Controller("blogController")
@RequestMapping(value = "/admin/blog")
public class BlogController extends MyController {
	@Autowired
	BlogService blogService;
	

/**
* 查询frame
*/
	@RequestMapping(value = "/frame")
	public String frame(Model model, HttpServletRequest request,String flag)throws Exception {
		return "/admin/blog/frame";
	}
	
/**
* 查询列表
*/
	@RequestMapping(value = "/list")
	public String list(Model model, HttpServletRequest request,String flag,String title,Blog blog)throws Exception {

		List list = blogService.getBlogList(request, blog);
		request.setAttribute("list", list);
		return "/admin/blog/list";
	}
	
/**
* 编辑保存（包含修改和添加）
*/
	@RequestMapping(value = "/editSave")
	public ResponseEntity editSave(Model model,HttpServletRequest request,Long id,String flag,Blog blog
		) throws Exception{
		int result = 0;
		if(id!=null){
			result = blogService.update(request, blog);
			
		}else{
		
			result = blogService.save(request, blog);
		}
		if(result==1){
			return renderData(true,"操作成功",null);
		}else{
			return renderData(false,"操作失败",null);
		}
	}
	
/**
* 删除信息
*/
	@RequestMapping(value = "/editDelete")
	public ResponseEntity editDelete(Model model,HttpServletRequest request,Long id,String flag) throws Exception {
		
		int result = blogService.deleteOne(request, id);
		if(result==1){
			return renderData(true,"操作成功",null);
		}else{
			return renderData(false,"操作失败",null);
		}
		
	}
	
/**
* 跳转到编辑页面
*/
	@RequestMapping(value = "/edit")
	public String edit(Model model, HttpServletRequest request,Long id,String flag)throws Exception {
		if(id!=null){
			//修改
			Blog blog = blogService.getBlog(request, id);
			model.addAttribute("map", blog);
		}String sql="select * from t_fenlei";
		List flList = db.queryForList(sql);
		model.addAttribute("flList", flList);
		return "/admin/blog/edit";
	}
}

一个ssm的mapping配置例子：


<?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="project.dao.BlogDao">
	<resultMap id="BaseResultMap" type="project.model.Blog">
		<id column="title" property="title"/>
		<id column="headPic" property="headPic"/>
		<id column="content" property="content"/>
		<id column="showDate" property="showDate"/>
		<id column="status" property="status"/>
		<id column="px" property="px"/>
		<id column="abc" property="abc"/>
		<id column="types" property="types"/>
		<id column="cNum" property="cNum"/>
		<id column="pNum" property="pNum"/>
		<id column="istj" property="istj"/>
	</resultMap>
	
	<insert id="insert">
		insert into t_blog(title,headPic,content,showDate,status,px,abc,types,cNum,pNum,istj) values(#{title},#{headPic},#{content},#{showDate},#{status},#{px},#{abc},#{types},#{cNum},#{pNum},#{istj})
	</insert>
	
	<update id="update">
	 update t_blog
	 <trim prefix="set" suffixOverrides=",">
	  <if test="title!=null">title=#{title},</if>
	  <if test="headPic!=null">headPic=#{headPic},</if>
	  <if test="content!=null">content=#{content},</if>
	  <if test="showDate!=null">showDate=#{showDate},</if>
	  <if test="status!=null">status=#{status},</if>
	  <if test="px!=null">px=#{px},</if>
	  <if test="abc!=null">abc=#{abc},</if>
	  <if test="types!=null">types=#{types},</if>
	  <if test="cNum!=null">cNum=#{cNum},</if>
	  <if test="pNum!=null">pNum=#{pNum},</if>
	  <if test="istj!=null">istj=#{istj},</if>
	 </trim>
	 where id=#{id}
	</update>
	<select id="getById" resultMap="BaseResultMap"
		parameterType="project.model.Blog">
		select * from t_blog where id=#{id}
	</select>
	
	<delete id="delete">  
        delete from t_blog where id=#{id}
	</delete>
	<select id="queryForList" resultMap="BaseResultMap" parameterType="project.model.Blog">
		select * from t_blog where 1=1 
		<if test="title!=null and title!=''">
		    and title like concat(concat('%',#{title}),'%') 
		</if>
		<if test="begin!=null and page_num!=null">limit #{begin},#{page_num}</if>
	</select>
	<select id="countAll" resultType="java.lang.Integer" parameterType="project.model.Blog">
		select count(1) from t_blog where 1=1 
		<if test="title!=null">
		    and title like concat(concat('%',#{title}),'%') 
		</if>
	</select>
</mapper>
