实体类，声明了id和name,以及对应的setter,getter

public class Category {
    private Integer id;
 
    private String name;
 
    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 == null ? null : name.trim();
    }
}

创建接口CategoryMapper，声明list方法

import java.util.List;
 
public interface CategoryMapper {
    List<Category> list();
}

创建接口CategoryService，声明list方法

import java.util.List;
public interface CategoryService{
    List<Category> list();
}

创建CategoryService接口的实现类CategoryServiceImpl

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class CategoryServiceImpl  implements CategoryService {
    @Autowired
    CategoryMapper categoryMapper;
    public List<Category> list(){
        return categoryMapper.list();
    };
 
}

创建访问控制器CategoryController

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
 
import java.util.List;
@Controller
@RequestMapping("")
public class CategoryController {
    @Autowired
    CategoryService categoryService;
  
    @RequestMapping("admin_category_list")
    public String list(Model model){
        List<Category> cs= categoryService.list();
        model.addAttribute("cs", cs);
        return "admin/listCategory";
    }
}

创建映射文件CategoryMapper.xml

<?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.how2java.tmall.mapper.CategoryMapper">
  <select id="list" resultType="Category">
    select * from   category order by id desc
  </select>
</mapper>

创建log4j.properties，开启日志

# Global logging configuration
log4j.rootLogger=ERROR, stdout
# MyBatis logging configuration...
log4j.logger.com.how2java.tmall=TRACE
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

在resources目录下新建jdbc.properties，配置数据库信息

#数据库配置文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=admin

在resources目录下新建applicationContext.xml

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

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

在resources目录下新建springMVC.xml

    <!-- 对上传文件的解析-->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

更改web.xml

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

在jsp目录中创建admin目录，接着创建listCategory.jsp文件

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8" import="java.util.*"%>
  
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@include file="../include/admin/adminHeader.jsp"%>
<%@include file="../include/admin/adminNavigator.jsp"%>
 
<script>
$(function(){
     
    $("#addForm").submit(function(){
        if(!checkEmpty("name","分类名称"))
            return false;
        if(!checkEmpty("categoryPic","分类图片"))
            return false;
        return true;
    });
});
 
</script>
