0、综合案例功能介绍



  • 以上是在综合案例要实现的功能。除了对数据的增删改查功能之外，还有一些复杂的功能，如批量删除，分页查询，条件查询等功能

    • 批量删除功能：每条数据前都有复选框，当我们选中多条数据并点击批量删除按钮后，会发送请求到后端并删除数据库指定的多条数据
    • 分页查询功能：当数据库中有很多数据的时候，我们不可能将所有的数据展示在一页里，这个时候就需要分页展示数据
    • 条件查询功能：数据库量大的时候，我们需要精确的查询一些想看到的数据，这个时候就需要通过条件查询

1、查询所有功能


  • 整体流程如下图所示



1.1、后端实现

1.1.1、dao方法实现


  • 在com.coolman.mapper.BrandMapper接口中定义抽象方法，使用@Select注解编写SQL语句

      1. // 查询所有品牌
      2. <settings>
      3.   <setting name="mapUnderscoreToCamelCase" value="true"/>
      4. </settings><settings>
      5.   <setting name="mapUnderscoreToCamelCase" value="true"/>
      6. </settings>@Select("select * from brand.tb_brand order by ordered")
      7. <settings>
      8.   <setting name="mapUnderscoreToCamelCase" value="true"/>
      9. </settings><settings>
      10.   <setting name="mapUnderscoreToCamelCase" value="true"/>
      11. </settings>List<Brand> selectAllBrands();
      复制代码

  • 由于表中有些字段名和实体类中的属性名没有对应，所以要进行相关配置

    • 方法1：在SQL语句中取别名

        1. // 查询所有品牌
        2. <settings>
        3.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        4. </settings><settings>
        5.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        6. </settings>@Select("select id, brand_name as brandName, company_name as companyName, ordered, description, status from brand.tb_brand order by ordered")
        7. <settings>
        8.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        9. </settings><settings>
        10.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        11. </settings>List<Brand> selectAllBrands();
        复制代码

    • 方法2：在BrandMapper.xml映射配置文件中定义结果映射，同时在使用注解开发的条件下在Mapper接口中使用ResultMap注解

        1. <resultMap id="brandResultMap" type="Brand">
        2. <settings>
        3.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        4. </settings><settings>
        5.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        6. </settings><settings>
        7.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        8. </settings><settings>
        9.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        10. </settings><result property="brandName" column="brand_name" />
        11. <settings>
        12.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        13. </settings><settings>
        14.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        15. </settings><settings>
        16.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        17. </settings><settings>
        18.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        19. </settings><result property="companyName" column="company_name" />
        20. <settings>
        21.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        22. </settings><settings>
        23.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        24. </settings></resultMap>
        复制代码
        1. //查询所有品牌
        2. <settings>
        3.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        4. </settings><settings>
        5.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        6. </settings>@Select("select * from brand.tb_brand order by ordered")
        7. <settings>
        8.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        9. </settings><settings>
        10.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        11. </settings>@ResultMap("brandResultMap")
        12. <settings>
        13.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        14. </settings><settings>
        15.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        16. </settings>List<Brand> selectAllBrands();
        复制代码

    • 方法3：在MyBatis配置文件中设置并开启驼峰自动命名映射

        1. <settings>
        2.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        3. </settings>
        复制代码


1.1.2、service实现


    1. // 查询所有品牌<settings>
    2.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    3. </settings><settings>
    4.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    5. </settings>public List selectAllBrands() {<settings>

5、servlet优化

5.1、背景


  • Web层的Servlet个数太多，不利于管理和编写

    • 模块的每一个功能都需要定义一个servlet，当模块的数量多时，就很容易造成servlet泛滥。

5.2、解决方法


  • 一个模块只定义一个servlet，模块中的每一个功能只需要在servlet中定义对应的方法，如下代码所示
    1. @WebServlet("/brand/*")public class BrandServlet {<settings>
    2.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    3. </settings><settings>
    4.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    5. </settings>//查询所有        public void selectAll(...) {}<settings>
    6.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    7. </settings><settings>
    8.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    9. </settings><settings>
    10.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    11. </settings><settings>
    12.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    13. </settings>//添加数据<settings>
    14.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    15. </settings><settings>
    16.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    17. </settings>public void add(...) {}<settings>
    18.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    19. </settings><settings>
    20.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    21. </settings><settings>
    22.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    23. </settings><settings>
    24.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    25. </settings> //修改数据<settings>
    26.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    27. </settings><settings>
    28.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    29. </settings>public void update(...) {}<settings>
    30.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    31. </settings><settings>
    32.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    33. </settings><settings>
    34.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    35. </settings><settings>
    36.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    37. </settings>//删除删除<settings>
    38.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    39. </settings><settings>
    40.   <setting name="mapUnderscoreToCamelCase" value="true"/>
    41. </settings>public void delete(...) {}}
    复制代码
5.3、思路


  • 当发送请求至servlet，tomcat会自动调用service()方法，源码如下所示


    • 我们一般在自定义的servlet中会重写doGet()和doPost()方法，当我们访问该servlet的时候会根据请求方式将请求分发给doGet()或者doPost()方法

  • 那么可以仿照这样的请求分发的思想，在service()方法中根据具体的操作调用对应的方法

    • 如：查询所有就调用selectAll()方法，添加企业信息就调用add()方法

5.4、具体实现


  • 定义一个通用的servlet类，在定义其他的servlet是不需要继承HttpServlet，而继承我们定义的BaseServlet，在BaseServlet中调用具体servlet（如BrandServlet）中的对应方法，如下所示

    • BaseServlet

        1. public class BaseServlet extends HttpServlet {<settings>
        2.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        3. </settings><settings>
        4.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        5. </settings>@Override<settings>
        6.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        7. </settings><settings>
        8.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        9. </settings>protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {<settings>
        10.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        11. </settings><settings>
        12.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        13. </settings><settings>
        14.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        15. </settings><settings>
        16.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        17. </settings>//进行请求的分发<settings>
        18.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        19. </settings><settings>
        20.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        21. </settings>}}
        复制代码

    • BrandServlet

        1. @WebServlet("/brand/*")public class BrandServlet extends BaseServlet {<settings>
        2.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        3. </settings><settings>
        4.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        5. </settings>//用户实现分页查询        public void selectAll(...) {}<settings>
        6.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        7. </settings><settings>

        9. </settings><settings>
        10.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        11. </settings><settings>
        12.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        13. </settings> //添加企业信息<settings>
        14.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        15. </settings><settings>
        16.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        17. </settings>public void add(...) {}<settings>
        18.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        19. </settings><settings>
        20.   <setting name="mapUnderscoreToCamelCase" value="true"/>

        25. </settings>//修改企业信息<settings>
        26.   <setting name="mapUnderscoreToCamelCase" value="true"/>

        29. </settings>public void update(...) {}<settings>

        33. </settings><settings>
        34.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        35. </settings><settings>
        36.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        37. </settings>//删除企业信息<settings>
        38.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        39. </settings><settings>
        40.   <setting name="mapUnderscoreToCamelCase" value="true"/>
        41. </settings>public void delete(...) {}}
        复制代码


  • 那么如何在BaseServlet中调用对应的方法，进行请求分发呢？

    • 可以规定在发送请求的时候，请求资源的二级路径（/brandServlet/selectAll）和需要调用的方法名相同，如下所示

      • 查询所有数据的路径以后就需要写成： http://localhost:8080/brand-case/brandServlet/selectAll
      • 添加数据的路径以后就需要写成： http://localhost:8080/brand-case/brandServlet/add
      • 修改数据的路径以后就需要写成： http://localhost:8080/brand-case/brandServlet/update
      • 删除数据的路径以后就需要写成： http://localhost:8080/brand-case/brandServlet/delete

    • 或者给在路径中添加一个参数，值为对应的方法名称，如下所示

      • 查询所有数据的路径以后就需要写成： http://localhost:8080/brand-case/brandServlet?action=selectAll
      • ...


  • 这样的话，在BaseServlet中就需要获取到资源的二级路径作为方法名或者路径中的action参数的值，然后调用该方法
5.4.1、后端代码

注意事项


  • BaseServlet和BrandServlet要放在同一个包下，否则因为BrandServlet中的方法全都是protected修饰的方法，必须要设置取出权限才可调用

    • method.setAccessible(true);

7、批量删除

7.1、后端实现

7.1.1、dao层实现
