今天完成的事情：

1. 完成了剩下两个表的增删改查

修补了一些原来的错误。


2. 完成了随机昵称生成


3. 完成了查询接口

没用任何奇怪的操作，和任务二做的一样，拿到所有结果直接 sub 一段返回···

能用就行


遇到的问题：

1. controller中注入 service 后没法启动

解决的方法：

web.xml 里面没有加上 spring的配置文件···

报错信息如下：

收获：

1. 搜索的实现

mapper.xml

<select id="search" parameterType="java.lang.String" resultMap="BaseResultMap">
  select
  id, name, introduction
  from gallery
  where concat(`name`, `introduction`)
  like #{keyword,jdbcType=VARCHAR}
</select>

mapper.java

List<Gallery> search(String keyword);

service

List<Map> search(String keyword);

serviceImpl

@Override
public List<Map> search(String keyword){
    List<Map> mapList = new ArrayList<>();
    Map<String, Object> stringObjectMap = new HashMap<>();
    List<Gallery> galleries = galleryMapper.search("%" + keyword + "%");
    for (Gallery g:
         galleries) {
        stringObjectMap.put("title", g.getName());
        stringObjectMap.put("introduction", g.getIntroduction());
        stringObjectMap.put("pic_url", pictureOf(g.getId()));
        stringObjectMap.put("work_url", "http://api.mogeek.cn/u/works/" + g.getId());
        mapList.add(stringObjectMap);
        stringObjectMap = new HashMap<>();
    }
    return mapList;
}

就是这么简单粗暴，剩下的就是按照前端发的请求来切数据了···


明天的计划：

1. 完成 controller
