每天进步一点点

本章的代码建立在第四章《Java框架整合--切分配置文件》的项目代码之上,链接如下:

http://www.cnblogs.com/java-zhao/p/5118184.html

在实际开发中,我们在使用mybatis的时候,会注解与xml形式一起使用。

1、二者的使用场景

xml使用场景(3个):

  • 条件不定的查询(eg.下边代码中的getAdminByConditions方法)
  • 增加对象返回自增主键(eg.下边代码的insertAdminWithBackId方法)
  • 在一个Mapper接口中,出现多个select查询(>=3个),且每个查询都需要写相同的返回@Results内容(这一部分内容通常很多),这样的话,为了使Mapper接口比较整洁,重复代码比较少,我们会将这些select方法的具体实现写在xml文件中,因为在xml文件的顶部我们就会配置与注解@Results异曲同工的东西。(当然,这一点如果嫌配置xml麻烦,这一点可忽略)

注意:前两条是硬性的,是注解所解决不了的,而第三条只是建议。

除了以上这三条之外,其他的都使用去注解就好。

2、代码实现

基本代码不变,这只列出修改过得代码:

2.1、ssmm0-userManagement:

AdminController

 1 package com.xxx.web.admin;
 2 
 3 import java.util.List;
 4 
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.stereotype.Controller;
 7 import org.springframework.web.bind.annotation.RequestMapping;
 8 import org.springframework.web.bind.annotation.RequestParam;
 9 import org.springframework.web.bind.annotation.ResponseBody;
10 import org.springframework.web.servlet.ModelAndView;
11 
12 import com.xxx.model.userManagement.Admin;
13 import com.xxx.service.userManagement.AdminService;
14 
15 /**
16  * adminController
17  */
18 @Controller
19 @RequestMapping("/admin")
20 public class AdminController {
21     
22     @Autowired
23     private AdminService adminService;
24     
25     /**
26      * 管理员注册
27      */
28     @ResponseBody
29     @RequestMapping("/register")
30     public boolean register(@RequestParam("username") String username,
31                             @RequestParam("password") String password){
32         Admin admin = new Admin();
33         admin.setUsername(username);
34         admin.setPassword(password);
35         
36         boolean isRegisterSuccess = adminService.register(admin);
37         
38         return isRegisterSuccess;
39     }
40     
41     /**
42      * 管理员登录
43      */
44     @RequestMapping("/login")
45     public ModelAndView login(@RequestParam("username") String username,
46                               @RequestParam("password") String password){
47         Admin admin = adminService.login(username, password);
48         
49         ModelAndView modelAndView = new ModelAndView();
50         if(admin == null){
51             modelAndView.addObject("message", "用户不存在或者密码错误!请重新输入");
52             modelAndView.setViewName("error");
53         }else{
54             modelAndView.addObject("admin", admin);
55             modelAndView.setViewName("userinfo");
56         }
57         
58         return modelAndView;
59     }
60     
61     /*****************************mybatis xml方式解决的问题*******************************/
62     /**
63      * 根据username或password查找List<Admin>
64      */
65     @ResponseBody
66     @RequestMapping("/findAdmin")
67     public List<Admin> findAdmin(@RequestParam(value="username",required=false) String username,
68                                     @RequestParam(value="password",required=false) String password,
69                                     @RequestParam("start") int start,
70                                     @RequestParam("limit") int limit){
71         List<Admin> adminList = adminService.findAdmin(username, password, start, limit);
72         return adminList;
73     }
74     
75     /**
76      * 插入一个用户并返回主键
77      * 注意:get请求也会自动装配(即将前台传入的username和password传入admin)
78      */
79     @ResponseBody
80     @RequestMapping("/insert")
81     public Admin insertAdminWithBackId(Admin admin){
82         return adminService.insertAdminWithBackId(admin);
83     }
84 }

说明:在这里增加了两个方法,具体看代码与注释

注:

  • springMVC通过get方式传递的属性值username、password也能自动装配到对象admin中

2.2、ssmm0-data:

24         return adminDao.login(username, password);
25     }
26     
27     /***********以下方法是为了测试mybatis中使用xml**********/
28     public List<Admin> findAdmin(String username, String password, int start, int limit){
29         return adminDao.findAdmin(username, password, start, limit);
30     }
31     
32     public Admin insertAdminWithBackId(Admin admin){
33         int record = adminDao.insertAdminWithBackId(admin);
34         if(record==1){
35             return admin;//这时的admin已经被赋予主键了
36         }
37         return null;
38     }
39 }

AdminDao

 8 import com.xxx.mapper.userManagement.AdminMapper;
 9 import com.xxx.model.userManagement.Admin;

14 @Repository
15 public class AdminDao {
16     @Autowired
17     private AdminMapper adminMapper;
18     
19     public boolean register(Admin admin){
20         return adminMapper.insertAdmin(admin)==1?true:false;
21     }
22     
23     public Admin login(String username ,String password){
24         return adminMapper.selectAdmin(username, password);
25     }
26     
27     public List<Admin> findAdmin(String username, String password, int start, int limit){
28         return adminMapper.getAdminByConditions(username, password, start, limit);
29     }
30     
31     public int insertAdminWithBackId(Admin admin){
32         return adminMapper.insertAdminWithBackId(admin);
33     }
34 }

AdminMapper

 1 package com.xxx.mapper.userManagement;
 2 
 3 import java.util.List;
 4 
 5 import org.apache.ibatis.annotations.Insert;
 6 import org.apache.ibatis.annotations.Param;
 7 import org.apache.ibatis.annotations.Result;
 8 import org.apache.ibatis.annotations.Results;
 9 import org.apache.ibatis.annotations.Select;
10 
11 import com.xxx.model.userManagement.Admin;
12 
13 /**
14  * 管理员Mapper
15  */
16 public interface AdminMapper {
17     
18     /**************注解**************/
19     @Insert("INSERT INTO userinfo(username, password) VALUES(#{username},#{password})")
20     public int insertAdmin(Admin admin);
21 
22     @Select("SELECT * FROM userinfo WHERE username = #{username} AND password = #{password}")
23     @Results(value = { 
24             @Result(id = true, column = "id", property = "id"),
25             @Result(column = "username", property = "username"),
26             @Result(column = "password", property = "password") })
27     public Admin selectAdmin(@Param("username") String username,
28                              @Param("password") String password);
29     
30     /***************xml**************/
31     /**
32      * 条件不定式查询
33      * 我们这里使用@Param指定参数,这样的话,在AdminMapper.xml中就不用再使用parameterType属性了;否则得写parameterType属性
34      */
35     public List<Admin> getAdminByConditions(@Param("username")String username,
36                                             @Param("password")String password, 
37                                             @Param("start")int start, 
38                                             @Param("limit")int limit);
39     
40     /**
41      * 返回主键
42      */
43     public int insertAdminWithBackId(Admin admin);
44 }
View Code

注意:在用xml传参的时候,

  • 如果你直接传参,eg.insertAdminWithBackId(Admin admin),则在xml中的insertAdminWithBackId方法处要添加parameterType;
  • 如果你用了注解传参的话,eg.getAdminByConditions(@Param("username")String username),则在xml中的getAdminByConditions方法处不用添加parameterType,当然,注解传参的时候,不能传引用类型,一般只传基本类型,eg.insertAdminWithBackId(@Param("admin")Admin admin)就是不行的

接口定义好之后,需要添加两个配置文件+修改两个配置文件。目录结构如下:

AdminMapper.xml(该xml的名字最好与对应接口的接口名完全相同)

 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 
 4 <!-- 指定工作空间,要与接口名相同,源代码没有去看,猜测应该是通过"这里的namespace.下边方法的id"来定位方法的 -->
 5 <mapper namespace="com.xxx.mapper.userManagement.AdminMapper">
 6     <!-- 指定字段映射 -->
 7     <resultMap type="Admin" id="adminResultMap">
 8         <id property="id"  column="id" jdbcType="INTEGER" />
 9         <result property="username" column="username" jdbcType="VARCHAR" />
10         <result property="password" column="password" jdbcType="VARCHAR" />
11     </resultMap>
12     
13     <select id="getAdminByConditions" resultMap="adminResultMap"><!-- 返回结果为上边指定的adminResultMap -->
14         <![CDATA[ SELECT * FROM userinfo WHERE 1=1 ]]>
15         <if test="username != null"><![CDATA[ AND username = #{username} ]]></if>
16         <if test="password != null"><![CDATA[ AND password = #{password} ]]></if>
17         <![CDATA[ ORDER BY id ASC LIMIT #{start}, #{limit} ]]>
18     </select>
19     
20     <!-- 若不需要自动返回主键,将useGeneratedKeys="true" keyProperty="id"去掉即可 -->
21     <insert id="insertAdminWithBackId" parameterType="Admin" useGeneratedKeys="true" keyProperty="id">
22        <![CDATA[
23        INSERT INTO userinfo 
24        (
25            username,
26            password
27        )
28        VALUES
29        (
30            #{username, jdbcType=VARCHAR},
31            #{password, jdbcType=VARCHAR}
32        )
33        ]]>
34    </insert>
35     
36 </mapper>
View Code

注意:

  • 该xml的名字最好与对应接口的接口名完全相同(eg.AdminMapper.xml对于应接口AdminMapper)
  • parameterType有无参照上边对AdminMapper处所讲的注意点
  • 返回自增主键有两种方法,我这里列出了最常用的也是最简单的一种

mybatis.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE configuration
 3     PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
 4     "http://mybatis.org/dtd/mybatis-3-config.dtd">
 5 
 6 <configuration>
 7     <properties>
 8         <property name="dialect" value="mysql" />
 9     </properties>
10     
11     <typeAliases>
12         <!-- 这样会将com.xxx.model包及其子包下的所有类起别名为相应的简单类名 -->
13         <package name="com.xxx.model"/>
14         <!-- 如果这样去起别名的话,每一个模型类都要写一个,就比较麻烦 -->
15         <!-- <typeAlias alias="Admin" type="com.xxx.model.userManagement.Admin"/> -->
16     </typeAliases>
17 </configuration>

注意:这个文件一般用于指定属性和别名。

  • 通常,属性只指定数据库方言即可;
  • 有两种别名方式指定,请参照上述代码给出的注释进行选择,一般而言,都会选择package方式的
