从零开始实现放置游戏（四）——实现后台管理系统（2）数值配置的增删查改
来源：cnblogs　　作者：丶谦信　　时间：2019/7/10 9:23:56　　对本文有异议

　　上一章我们将RMS后台管理系统搭建完毕，本章我们就在这个系统上实现录入游戏配置的功能。目前我们需要配置四项，每个等级的人物属性，每个等级的升级经验，游戏地图，地图中的怪物。下面我们以游戏地图配置为例子，实现对它的增删查改功能。

一、数据访问层的实现

　　首先，我们需要定义地图类，这个类在各个模块通用，因此要定义在facade模块中。我们新建一个包com.idlewow.map.model，在其中新建WowMap类，代码如下：

  1. package com.idlewow.map.model;
  3. import com.idlewow.common.model.BaseModel;
  4. import lombok.Data;
  6. import java.io.Serializable;
  8. @Data
  9. public class WowMap extends BaseModel implements Serializable {
  10.     private String name;
  11.     private Integer occupy;
  12.     private String description;
  13. }

　　然后，我们在core模块中实现数据访问层的逻辑。新建com.idlewow.map.mapper包，并新建一个接口类WowMapMapper，在接口中定义我们需要用到的一些增删查改方法，代码如下：

  1. package com.idlewow.map.mapper;
  3. import com.idlewow.map.model.WowMap;
  4. import com.idlewow.query.model.WowMapQueryParam;
  6. import java.util.List;
  8. public interface WowMapMapper {
  9.     int insert(WowMap wowMap);
  11.     int batchInsert(List<WowMap> list);
  13.     int update(WowMap levelProp);
  15.     int delete(String id);
  17.     WowMap find(String id);
  19.     List<WowMap> list(WowMapQueryParam queryParam);
  21.     int count(WowMapQueryParam queryParam);
  22. }

　　Mapper接口类，只定义了方法，具体实现需要我们在该包下新建一个WowMapMapper.xml文件，在这个文件中，通过SQL语句实现接口中的方法：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  3. <mapper namespace="com.idlewow.map.mapper.WowMapMapper">
  4.     <resultMap id="BaseResultMap" type="com.idlewow.map.model.WowMap">
  5.         <result column="id" property="id"/>
  6.         <result column="name" property="name"/>
  7.         <result column="occupy" property="occupy"/>
  8.         <result column="description" property="description"/>
  9.         <result column="create_user" property="createUser"/>
  10.         <result column="update_user" property="updateUser"/>
  11.         <result column="create_time" property="createTime"/>
  12.         <result column="update_time" property="updateTime"/>
  13.         <result column="is_delete" property="isDelete"/>
  14.         <result column="version" property="version"/>
  15.     </resultMap>
  16.     <!-- 添加 -->
  17.     <insert id="insert">
  18.         insert into map (name, occupy, description, create_user)
  19.         values (#{name}, #{occupy}, #{description}, #{createUser})
  20.     </insert>
  21.     <!-- 批量添加 -->
  22.     <insert id="batchInsert">
  23.         insert into map (name, occupy, description, create_user)
  24.         values
  25.         <foreach collection="list" item="item" separator=",">
  26.             (#{item.name}, #{item.occupy}, #{item.description}, #{item.createUser})
  27.         </foreach>
  28.     </insert>
  29.     <!-- 修改 -->
  30.     <update id="update">
  31.         update map
  32.         set name = #{name},
  33.             occupy = #{occupy},
  34.             description = #{description},
  35.             update_user = #{updateUser},
  36.             version = version + 1
  37.         where id = #{id} and is_delete = 0
  38.     </update>
  39.     <!-- 删除 -->
  40.     <update id="delete" parameterType="String">
  41.         update map
  42.         set is_delete = 1
  43.         where id = #{id}
  44.     </update>
  45.     <!-- id查询 -->
  46.     <select id="find" resultMap="BaseResultMap">
  47.         select *
  48.         from map
  49.         where id = #{id} and is_delete = 0
  50.     </select>
  51.     <!-- 列表查询总数 -->
  52.     <select id="count" resultType="int">
  53.         select count(1)
  54.         from map
  55.         <where>
  56.             is_delete = 0
  57.             <if test="name != null and name != ''">
  58.                 and name like concat('%', #{name}, '%')
  59.             </if>
  60.         </where>
  61.     </select>
  62.     <!-- 列表查询 -->
  63.     <select id="list" resultMap="BaseResultMap">
  64.         select *
  65.         from map
  66.         <where>
  67.             is_delete = 0
  68.             <if test="name != null and name != ''">
  69.                 and name like concat('%', #{name}, '%')
  70.             </if>
  71.         </where>
  72.         <if test="pageParam != null">
  73.             limit ${(pageParam.pageIndex - 1) * pageParam.pageSize}, ${pageParam.pageSize}
  74.         </if>
  75.     </select>
  76. </mapper>
WowMapMapper.xml

　　最后，我们新建com.idlewow.map.manager包，新建一个类WowMapManager，此类通过调用mapper来实现具体业务：

  1. package com.idlewow.map.manager;
  3. import com.idlewow.common.model.PageList;
  4. import com.idlewow.map.mapper.WowMapMapper;
  5. import com.idlewow.map.model.WowMap;
  6. import com.idlewow.query.model.WowMapQueryParam;
  7. import org.springframework.beans.factory.annotation.Autowired;
  8. import org.springframework.stereotype.Component;
  10. import java.util.List;
  12. @Component
  13. public class WowMapManager {
  14.     @Autowired
  15.     WowMapMapper wowMapMapper;
  17.     public void insert(WowMap wowMap) {
  18.         int effected = wowMapMapper.insert(wowMap);
  19.         if (effected == 0) {
  20.             throw new RuntimeException("sql effected 0 rows");
  21.         }
  22.     }
  24.     public void batchInsert(List<WowMap> list) {
  25.         int splitSize = 100;
  26.         int index = 0;
  27.         int total = list.size();
  28.         while (index <= total) {
  29.             int end = index + splitSize;
  30.             if (end > total) {
  31.                 end = total;
  32.             }
  34.             List<WowMap> sublist = list.subList(index, end);
  35.             int effected = wowMapMapper.batchInsert(sublist);
  36.             if (effected == 0) {
  37.                 throw new RuntimeException("sql effected 0 rows");
  38.             }
  40.             index += splitSize;
  41.         }
  42.     }
  44.     public void update(WowMap t) {
  45.         int effected = wowMapMapper.update(t);
  46.         if (effected == 0) {
  47.             throw new RuntimeException("sql effected 0 rows");
  48.         }
  49.     }
  51.     public void delete(String id) {
  52.         int effected = wowMapMapper.delete(id);
  53.         if (effected == 0) {
  54.             throw new RuntimeException("sql effected 0 rows");
  55.         }
  56.     }
  58.     public WowMap find(String id) {
  59.         WowMap wowMap = wowMapMapper.find(id);
  60.         return wowMap;
  61.     }
  63.     public PageList<WowMap> list(WowMapQueryParam queryParam) {
  64.         PageList<WowMap> pageList = new PageList<WowMap>();
  65.         int count = wowMapMapper.count(queryParam);
  66.         List<WowMap> list = wowMapMapper.list(queryParam);
  67.         pageList.setTotalCount(count);
  68.         pageList.setData(list);
  69.         pageList.setPageParam(queryParam.getPageParam());
  70.         return pageList;
  71.     }
  72. }

　　另外，@Componet注解需要依赖spring-context包。还有我们写SQL的xml文件是资源文件，但为了方便查看编辑，我们直接把它放在了代码目录下，所以编译的时候不会被打包，需要在pom中添加配置如下：

  1.     </dependencies>
  2.         ........
  3.         ........
  4.         <dependency>
  5.             <groupId>org.springframework</groupId>
  6.             <artifactId>spring-context</artifactId>
  7.             <version>5.1.6.RELEASE</version>
  8.         </dependency>
  9.     </dependencies>
  10.     <build>
  11.         <resources>
  12.             <resource>
  13.                 <directory>src/main/java</directory>
  14.                 <includes>
  15.                     <include>**/*.xml</include>
  16.                     <include>**/*.properties</include>
  17.                 </includes>
  18.                 <filtering>false</filtering>
  19.             </resource>
  20.         </resources>
  21.     </build>

　　这样，我们的数据访问层逻辑就全部实现了。通过在RMS模块的controller中注入manager，即可实现对底层数据的访问。

二、controller层的实现

　　在com.idlewow.rms.controller包中，新建类MapController，在Contoller中，我们初步实现了对数据的增删查改。注意，这里list()方法，返回的字符串“/manage/map/list"，代表视图所在路径，根据spring-mvc.xml中配置的视图路由解析规则，即返回/WEB-INF/views/manage/map/list.jsp页面。但如果在该方法上加上注解@ResponseBody，则代表直接返回该字符串，不会去寻找视图。在post方法中，我们就是直接返回数据的json串。代码如下：

  1. package com.idlewow.rms.controller;
  3. import com.idlewow.common.model.CommonResult;
  4. import com.idlewow.common.model.PageList;
  5. import com.idlewow.map.manager.WowMapManager;
  6. import com.idlewow.map.model.WowMap;
  7. import com.idlewow.query.model.WowMapQueryParam;
  8. import org.springframework.beans.factory.annotation.Autowired;
  9. import org.springframework.stereotype.Controller;
  10. import org.springframework.ui.Model;
  11. import org.springframework.web.bind.annotation.PathVariable;
  12. import org.springframework.web.bind.annotation.RequestBody;
  13. import org.springframework.web.bind.annotation.RequestMapping;
  14. import org.springframework.web.bind.annotation.RequestMethod;
  15. import org.springframework.web.bind.annotation.RequestParam;
  16. import org.springframework.web.bind.annotation.ResponseBody;
  19. @Controller
  20. @RequestMapping("/manage/map")
  21. public class MapController extends BaseController {
  22.     @Autowired
  23.     WowMapManager wowMapManager;
  25.     @RequestMapping("/list")
  26.     public Object list() {
  27.         return "/manage/map/list";
  28.     }
  30.     @ResponseBody
  31.     @RequestMapping(value = "/list", method = RequestMethod.POST)
  32.     public Object list(@RequestParam(value = "page", defaultValue = "1") int pageIndex, @RequestParam(value = "limit", defaultValue = "10") int pageSize, WowMapQueryParam queryParam) {
  33.         queryParam.setPage(pageIndex, pageSize);
  34.         PageList<WowMap> pageList = wowMapManager.list(queryParam);
  35.         return this.parseTable(pageList);
  36.     }
  38.     @RequestMapping("/add")
  39.     public Object add() {
  40.         return "/manage/map/add";
  41.     }
  43.     @ResponseBody
  44.     @RequestMapping(value = "/add", method = RequestMethod.POST)
  45.     public Object add(@RequestBody WowMap wowMap) {
  46.         try {
  47.             wowMap.setCreateUser(this.currentUserName());
  48.             wowMapManager.insert(wowMap);
  49.             return CommonResult.success();
  50.         } catch (Exception ex) {
  51.             return CommonResult.fail();
  52.         }
  53.     }
  55.     @RequestMapping(value = "/edit/{id}", method = RequestMethod.GET)
  56.     public Object edit(@PathVariable String id, Model model) {
  57.         WowMap wowMap = wowMapManager.find(id);
  58.         model.addAttribute(wowMap);
  59.         return "/manage/map/edit";
  60.     }
  62.     @ResponseBody
  63.     @RequestMapping(value = "/edit/{id}", method = RequestMethod.POST)
  64.     public Object edit(@PathVariable String id, @RequestBody WowMap wowMap) {
  65.         try {
  66.             if (!id.equals(wowMap.getId())) {
  67.                 return CommonResult.fail("id不一致");
  68.             }
  70.             wowMap.setUpdateUser(this.currentUserName());
  71.             wowMapManager.update(wowMap);
  72.             return CommonResult.success();
  73.         } catch (Exception ex) {
  74.             return CommonResult.fail();
  75.         }
  76.     }
  78.     @ResponseBody
  79.     @RequestMapping(value = "/delete/{id}", method = RequestMethod.POST)
  80.     public Object delete(@PathVariable String id) {
  81.         try {
  82.             wowMapManager.delete(id);
  83.             return CommonResult.success();
  84.         } catch (Exception ex) {
  85.             return CommonResult.fail();
  86.         }
  87.     }
  88. }
MapController.java

　　其中, CommonResult类是我定义的一个通用的结果返回类，PageList和PageParam是分页相关的辅助类，WowMapQueryParam是列表查询的参数类。

　　另外，前端列表展示使用了layui的datatable，需要给他返回对应的数据结构。因此，我们定义一个抽象类BaseController，实现对列表数据结构的转换，同时提供查询当前登录用户的方法。其他的Controller如无特殊情况均继承BaseController，代码如下：

  1. package com.idlewow.rms.vo;
  3. import lombok.Data;
  5. import java.io.Serializable;
  6. import java.util.List;
  8. @Data
  9. public class LayuiDataTable<T> implements Serializable {
  10.     private Integer code;
  11.     private String message;
  12.     private Integer count;
  13.     private List<T> data;
  14. }
LayuiDataTable.java
  1. package com.idlewow.rms.controller;
  3. import com.idlewow.admin.model.SysAdmin;
  4. import com.idlewow.common.model.PageList;
  5. import com.idlewow.rms.vo.LayuiDataTable;
  6. import org.springframework.beans.factory.annotation.Autowired;
  8. import javax.servlet.http.HttpSession;
  10. public abstract class BaseController {
  11.     private static final String LoginUserKey = "loginuser";
  12.     @Autowired
  13.     protected HttpSession httpSession;
  15.     protected SysAdmin currentUser() {
  16.         return (SysAdmin) httpSession.getAttribute(LoginUserKey);
  17.     }
  19.     protected String currentUserName() {
  20.         return this.currentUser().getUsername();
  21.     }
  23.     protected LayuiDataTable parseTable(PageList pageList) {
  24.         LayuiDataTable dataTable = new LayuiDataTable();
  25.         dataTable.setMessage("读取成功");
  26.         dataTable.setCode(0);
  27.         dataTable.setCount(pageList.getTotalCount());
  28.         dataTable.setData(pageList.getData());
  29.         return dataTable;
  30.     }
  31. }
BaseController.java

　　写完控制器，前端页面，我们直接套用x-admin的模板。在/WEB-INF/views/manage/map目录下，创建页面：

  1. <%@ page contentType="text/html;charset=UTF-8" language="java" %>
  2. <%@ include file="/authorize.jsp" %>
  3. <!DOCTYPE html>
  4. <html class="x-admin-sm">
  5. <head>
  6.     <meta charset="UTF-8">
  7.     <title>地图管理</title>
  8.     <meta name="renderer" content="webkit">
  9.     <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
  10.     <meta name="viewport"
  11.           content="width=device-width,user-scalable=yes, minimum-scale=0.4, initial-scale=0.8,target-densitydpi=low-dpi"/>
  12.     <link rel="stylesheet" href="<%=path%>/css/font.css">
  13.     <link rel="stylesheet" href="<%=path%>/css/xadmin.css">

  16. </head>
  17. <body>
  18. <div class="x-nav">

  24.           </span>
  25.     <a class="layui-btn layui-btn-small" style="line-height:1.6em;margin-top:3px;float:right"
  26.        onclick="location.reload()" title="刷新">

三、项目启动

　　本次，我们修改了facade和core项目，这两个项目是作为jar包被rms模块引用的，因此必须先将其编译打包，这里我们用第（二）章定义的打包命令直接将整个项目重新打包。以后凡是jar包项目有改动，我们启动web项目前，都先重新打包一遍。

　　另外，maven的编译插件可能默认的jdk版本是1.5，我们在pom中配置一下，配成1.8，配置如下：

  1.     <build>
  2.         <plugins>
  3.             <plugin>
  4.                 <groupId>org.apache.maven.plugins</groupId>
  5.                 <artifactId>maven-compiler-plugin</artifactId>
  6.                 <configuration>
  7.                     <source>1.8</source>
  8.                     <target>1.8</target>
  9.                 </configuration>
  10.             </plugin>
  11.             
  12.             …………
  13.             …………
  14.         </plugins>
  15.     </build>

　　OK，全部搞定之后，我们运行一下，看下效果：

　　

 

小结

　　本章，我们初步实现了后台管理系统数据配置的增删查改，但还有很多功能不完善。

　　比如，添加、编辑时的数据没有进行校验；单个录入数据太麻烦，想要通过excel批量录入；出现异常时缺乏相应的日志记录，等等。

　　这些内容，我们都将在后面的章节中持续完善。
