springboot集成mybatis
1.新建Springboot项目(略)
2.导入相关依赖
<!--spring-boot--> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.6.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <!--web--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--test--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!--mybatis--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.1</version> </dependency> <!--mysql--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!--Druid 数据源--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.21</version> </dependency> <!--devtools热部署--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <scope>true</scope> </dependency> <!-- swagger --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <!-- swagger-ui --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency> </dependencies> <build> <plugins> <!--maven插件--> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <!--加载xml等文件为资源文件--> <resources> <resource> <directory>src/main/resources</directory> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> <include>**/*.tld</include> </includes> <filtering>false</filtering> </resource> </resources> </build>
3. 修改application.yml配置文件
server: port: 5000 #端口号 servlet: context-path: /pdzx #项目路径 spring: datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/pdzx?characterEncoding=utf8&useSSL=false&allowMultiQueries=true&serverTimezone=GMT%2B8 username: xxx password: xxx jackson: #格式化日期 date-format: yyyy-MM-dd HH:mm:ss #时区配置 time-zone: Asia/Shanghai devtools: restart: enabled: true #设置开启热部署 additional-paths: src/main/java #重启资源目录 mybatis: type-aliases-package: com.pdzx.po #别名 mapper-locations: classpath:com/pdzx/mapper/*.xml #mybatis的sql文件xml路径配置
3. 新建包名,如下图
dao层
@Repository public interface VideoInfoMapper { int deleteByPrimaryKey(Integer id); int insert(VideoInfo record); int insertSelective(VideoInfo record); VideoInfo selectByPrimaryKey(Integer id); int updateByPrimaryKeySelective(VideoInfo record); int updateByPrimaryKey(VideoInfo record); }
service层
public interface VideoInfoService { VideoInfo selectByPrimaryKey(Integer id); }
实现类
@Service public class VideoInfoServiceImpl implements VideoInfoService { @Autowired private VideoInfoMapper videoInfoMapper; @Override public VideoInfo selectByPrimaryKey(Integer id) { return videoInfoMapper.selectByPrimaryKey(id); } }
controller层
@RequestMapping("video")
@RestController
public class VideoInfoController {
@Autowired
private VideoInfoService videoInfoService;
@GetMapping("/selectByPrimaryKey")
public VideoInfo selectByPrimaryKey(Integer id){
return videoInfoService.selectByPrimaryKey(id);
}
@GetMapping("/hello")
public String hello(){
return "hello springboot-mybatis-xml";
}
@GetMapping("/hi")
public String hi(){
return "hi springboot-mybatis-xml";
}
}
7.生成文件后在启动类中添加注解@MapperScan
@MapperScan("com.pdzx.dao")
@SpringBootApplication
public class VideoApplication {
public static void main(String[] args) {
SpringApplication.run(VideoApplication.class);
}
}
8.访问以下路径,测试
http://localhost:5000/pdzx/video/selectByPrimaryKey?id=83
看结果
至此,springboot集成mybatis成功
springboot集成热部署
1.注意依赖
<!--devtools热部署-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
<scope>true</scope>
</dependency>
2.注意配置
spring: devtools: restart: enabled: true #设置开启热部署 additional-paths: src/main/java #重启资源目录
3.设置IDEA的自动编译：,如图
4.安装ctrl + shift + alt + /,选择Registry,勾上 Compiler autoMake allow when app running,如图
5.重启idea即可生效
SpringBoot整合Swagger2
1.两个Swagger2相关的依赖
<!-- swagger --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <!-- swagger-ui --> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency>
2.Swagger2配置
package com.pdzx.config; import springfox.documentation.service.Contact; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import springfox.documentation.builders.ApiInfoBuilder; import springfox.documentation.builders.PathSelectors; import springfox.documentation.builders.RequestHandlerSelectors; import springfox.documentation.spi.DocumentationType; import springfox.documentation.spring.web.plugins.Docket; import springfox.documentation.swagger2.annotations.EnableSwagger2; /** * Created by bianxh on 2019/1/21. */ @Configuration @EnableSwagger2//启用Swagger2 public class SwaggerApp { //http://localhost:5000/pdzx/swagger-ui.html 项目路径/swagger-ui.html @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .pathMapping("/")//配置映射路径和要扫描的接口的位置 .select() .apis(RequestHandlerSelectors.basePackage("com.pdzx.controller"))//配置要扫描的接口的位置 .paths(PathSelectors.any()) .build().apiInfo(new ApiInfoBuilder()//配置一下Swagger2文档网站的信息 .title("SpringBoot整合Swagger")//网站的title .description("本站是平大客户端的接口文档信息")//网站的描述 .version("9.0")//接口版本 .contact(new Contact("平大开发部","http://www.shpingda.com/","xxx@gmail.com"))//联系人的信息 .license("The Apache License")//使用的协议 .licenseUrl("http://www.baidu.com")// .build()); } }
3.创建接口
@RestController @Api(tags = "用户管理相关接口")//可以用来标记当前Controller的功能 @RequestMapping("/user") public class UserController { @PostMapping("/addUser") @ApiOperation("添加用户的接口")//用来标记一个方法的作用 @ApiImplicitParams(//如果有多个参数，多个@ApiImplicitParam注解需要放在一个@ApiImplicitParams注解中 { //用来描述一个参数，可以配置参数的中文含义，也可以给参数设置默认值，这样在接口测试的时候可以避免手动输入 @ApiImplicitParam(name = "username", value = "用户名", defaultValue = "李四"), //假如开发者需要指定一个参数必填，@RequestParam(required = true)注解不能省略 @ApiImplicitParam(name = "address", value = "用户地址", defaultValue = "深圳", required = true) } ) public User addUser(@RequestParam( "username") String username, @RequestParam( "address") String address) { User user = new User(); user.setUsername(username); user.setAddress(address); return user; } @GetMapping("/getUserById") @ApiOperation("根据id查询用户的接口") @ApiImplicitParam(name = "id", value = "用户id", defaultValue = "99", required = true) public User getUserById(@RequestParam( "id") Integer id) { User user = new User(); user.setId(id); return user; } @PutMapping("/updateUserById") @ApiOperation("根据id更新用户的接口")//如果参数是一个对象（例如上文的更新接口），对于参数的描述也可以放在实体类中 public User updateUserById(@RequestBody User user) { return user; } }
user
@ApiModel public class User { @ApiModelProperty(value = "用户id") private Integer id; @ApiModelProperty(value = "用户名") private String username; @ApiModelProperty(value = "用户地址") private String address; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } }
4.访问一下路径(项目路径/swagger-ui.html)
看结果
5.测试,点击Execute按钮，表示发送请求进行测试。测试结果会展示在下面的Response中
