1.spring boot 特点
2. 创建工程
最后的文件结构如下图
3. Gril.java
package girl; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; /** * Created by Think on 2017/10/3. */ @Entity public class Girl { @Id @GeneratedValue private Integer id; private String cupSize; private Integer age; public Girl(){} public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getCupSize() { return cupSize; } public void setCupSize(String cupSize) { this.cupSize = cupSize; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
4. ComApplication
package girl; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class ComApplication { public static void main(String[] args) { SpringApplication.run(ComApplication.class, args); } }
5. 创建接口
package girl; import org.springframework.data.jpa.repository.JpaRepository; /** * Created by Think on 2017/10/3. */ public interface GirlRepository extends JpaRepository<Girl, Integer>{ }
5. GirlProperties.java
package girl; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; /** * Created by Think on 2017/10/3. */ @Component @ConfigurationProperties(prefix = "girl") public class GirlProperties { private String cupSize; public String getCupSize() { return cupSize; } public void setCupSize(String cupSize) { this.cupSize = cupSize; } private Integer age; public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
6. 配置文件
使用的数据库为MySql
application.yml
spring: profiles: active: prod datasource: driver-class-name: com.mysql.jdbc.Driver url: jdbc:mysql://127.0.0.1:3306/dbgirl username: root password: 123456 jpa: hibernate: ddl-auto: update show-sql: true
application-dev.yml
server: port: 8080 girl: cupSize: B age: 18
application-prod.yml
server: port: 8082 girl: cupSize: F age: 18
7. Controller文件
package girl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import java.util.List; /** * Created by Think on 2017/10/3. */ @RestController public class GirlController { @Autowired private GirlRepository girlRepository; @Autowired private GirlService girlService; /** * 查詢所以女生列表 * @return */ @GetMapping(value = "/girls") public List<Girl> girlList(){ return girlRepository.findAll(); } /** * 添加一個女生 * @param cupSize * @param age * @return */ @PostMapping(value = "/girls") public Girl girlAdd(@RequestParam("cupSize") String cupSize, @RequestParam("age") Integer age){ Girl girl = new Girl(); girl.setCupSize(cupSize); girl.setAge(age); return girlRepository.save(girl); } @PostMapping(value = "/girls/two") public void girlTwo(){ girlService.insertTow(); } }
8. pom配置
