Spring Boot（Smart Moon项目）集成Mybatis

Spring Boot（Smart Moon项目）集成Mybatis

一、Spring引入Mybatis

• 编辑项目根目录的pom.xml，添加以下内容

  
  
       org.mybatis
       mybatis
       3.5.10
  
  
  
       org.mybatis.spring.boot
       mybatis-spring-boot-starter
       2.2.2
  
  

二、配置Mybatis generator自动生成CURD接口基础代码

• resource目录下配置generator.properties

  jdbc.driverLocation=D:\\SQL\\mysql-connector-8.0.23\\mysql-connector-java-8.0.23.jar
  jdbc.driverClass=com.mysql.cj.jdbc.Driver #需要指定连接驱动路径
  jdbc.connectionURL=jdbc:mysql://localhost:3306/database_name?characterEncoding=utf-8
  jdbc.userId=root
  jdbc.password=your_password
  
  

  pom.xml
  
      
          
              org.springframework.boot
              spring-boot-maven-plugin
          
          
          
              org.mybatis.generator
              mybatis-generator-maven-plugin
              1.3.2
              
                  true
                  true
              
          
      
  
  
  

• resource目录下配置generatorConfig.xml

  如若：http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd 报红，可以将此链接复制到浏览器打开，下载文件后，存在在自定义路径，然后编辑IEDA的file -> setting -> Schemas and DTDs -> 找到EXternal schemas and DTDs：点击 + 号，

  • URL填写http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd
  • File: 浏览找到文件下载后的存放位置，点击apply -> OK 退出

  
  

• 编辑Run配置

  • 点击工具栏Run -> Edit Configurations…

    

  • 点击+号 -> 选择maven，配置如下内容后点击apply -> Ok 退出：

    • Name: mybatis-generator 【可以自定义】
    • Run: mybatis-generator:generate -e

    

  • 点击Run选择：mybatis-generator，自动生成配置generatorConfig.xml文件配置中， 注释下的表的对应CURD基础代码

三、编写Controller

• 项目路径src\main\java\com\demo\smartmoon新建controller包，新建SysUserController【本项目使用】

  
  @RestController
  @RequestMapping(value = "/api/2/user", produces = MediaType.APPLICATION_JSON_VALUE)
  public class SysUserController {
      @Autowired
      private SysUserService sysUserService;
      
      @GetMapping(value = "/findByID")
      public Object findByID(@RequestParam Long id){
          return Response.success(sysUserService.findByID(id));
      }
  
      @ApiOperation(value = "新增用户信息")
      public Object insertSysUser(@RequestBody SysUser sysUser){
          return Response.success(sysUserService.insertSysUser(sysUser));
      }
  }
  

  • 测试效果：

    

四、对接Knife4j

• application.yml配置文件开启knife4j

  knife4j:
    # 开启增强配置
    enable: true
  

• controller新增注解

  
  @RestController
  @RequestMapping(value = "/api/2/user", produces = MediaType.APPLICATION_JSON_VALUE)
  @EnableOpenApi
  @Api(value = "信息管理", tags="账户管理")
  public class SysUserController {
      @Autowired
      private SysUserService sysUserService;
  
      @ApiOperation(value = "根据ID查询账户列表")
      @GetMapping(value = "/findByID")
      @ApiOperationSupport(author = "xuanyu.li")
      public Object findByID(@RequestParam Long id){
          System.out.println(id);
          return Response.success(sysUserService.findByID(id));
      }
  
      @ApiOperation(value = "新增用户信息")
      @PostMapping (value = "/insertSysUser")
      @ApiOperationSupport(author = "xuanyu.li")
      public Object insertSysUser(@RequestBody SysUser sysUser){
          return Response.success(sysUserService.insertSysUser(sysUser));
      }
  }
  

• 实体类model新增注解【如果想要在knife4j的swagger models看见】

  
  @Data
  @ApiModel(value = "SysUser",description = "用户实体对象")
  public class SysUser {
      @ApiModelProperty(value = "主键id", name = "id")
      private Long id;
  
      @ApiModelProperty(value = "name", name = "name")
      private String name;
  
      @ApiModelProperty(value = "nickName", name = "nickName")
      private String nickName;
  
      @ApiModelProperty(value = "avater", name = "avater")
      private String avater;
  
      @ApiModelProperty(value = "salt", name = "salt")
      private String salt;
  
      @ApiModelProperty(value = "password", name = "password")
      private String password;
  
      @ApiModelProperty(value = "email", name = "email")
      private String email;
  
      @ApiModelProperty(value = "mobile", name = "mobile")
      private String mobile;
  
      @ApiModelProperty(value = "status", name = "status")
      private Byte status;
  
      @ApiModelProperty(value = "deptId", name = "deptId")
      private Long deptId;
  ......【略，根据自己表确定】
  

• 效果：
