springboot整合springmvc+hibernate+swagger

SpringBoot+SpringMvc+Hibernate整合

SpringBoot+SpringMvc+Hibernate+Swagger簡單的整合步驟 。使用Eclipse工具1、新建一個maven專案

2、pom.xm設定

            <version>11.2.0.1.0</version>
        </dependency>
  </dependencies>
</project>

3、配置application.properties

#mysql\u6570\u636E\u5E93\u914D\u7F6E
spring.datasource.url=jdbc:mysql://localhost:3306/springmvc?characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
spring.datasource.min-idle=5
spring.datasource.initial-size=5
​
spring.jpa.database = MYSQL
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
​
#oracle\u6570\u636E\u5E93\u914D\u7F6E
#spring.datasource.url=jdbc:oracle:thin:@192.168.80.10:1521:orcl
#spring.datasource.username=wateruser
#spring.datasource.password=itcast
#spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
#spring.datasource.max-idle=10
#spring.datasource.max-wait=10000
#spring.datasource.min-idle=5
#spring.datasource.initial-size=5
​
server.port=8080
​
#Swagger Default Access Address : http://localhost:8080/swagger-ui.html

3、Repository介面層

package com.springboot.service.repository;
​
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.springboot.service.entity.User;
​
public interface UserRepository extends JpaRepository<User, Integer> {
    @Query(value = "SELECT u FROM User u WHERE u.id = ?")
    public User getUserById(Integer id);
}

4、實體類Entity層

package com.springboot.service.entity;
​
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
​
@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue
    @Column(name = "id")
    private Integer id;
    @Column(name = "username")
    private String username;
    @Column(name = "birthday")
    private Date birthday;
    @Column(name = "sex")
    private String sex;
    @Column(name = "address")
    private String address;
    省略set/get方法
}

5.web控制層

package com.springboot.web;
​
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.springboot.service.entity.User;
import com.springboot.service.repository.UserRepository;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
​
@RestController
@RequestMapping(value = "/user")
@Api(value = "使用者資訊")
@EnableAutoConfiguration
public class UserController {
​
    @Autowired
    private UserRepository userRepository;
    
    @GetMapping(value = "/getUserById")
    @ApiOperation(value = "通過使用者ID查詢使用者資訊")
    public User getUserById(@RequestParam(name = "id") Integer id){
        List<User> users = userRepository.findAll();
        return userRepository.getUserById(id);
    }
}
​

6、Application啟動類

package com.springboot.application;
​
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
​
@SpringBootApplication
@ComponentScan(basePackages={"com.springboot"}) // 掃描該包路徑下的所有spring元件
@EnableJpaRepositories("com.springboot.service.repository") // JPA掃描該包路徑下的Repositorie
@EntityScan("com.springboot.service.entity") // 掃描實體類
@EnableSwagger2 // Swagger
public class Application {
​
    public static void main(String[] args) {        
        SpringApplication.run(Application.class, args);
    }
}

7、配置Swagger 的一個Swagger配置類,放在啟動類掃描的包下,建議和啟動類放在同一目錄下;

package com.springboot.application;
​
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.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
​
@Configuration
public class SwaggerConfig {
​
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.springboot.web"))
                .paths(PathSelectors.any())
                .build();
    }
    
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("springboot利用swagger構建api文件")
                .description("簡單優雅的restfun風格")
                .termsOfServiceUrl("http://blog.csdn.net/saytime")
                .version("2.0")
                .build();
    }
}

Run as --- java Application就可以啟動專案

注意:

maven除了本地化之外,還需在 .../conf/setting.xml檔案中,增加以下配置,主要和工程中配置中央倉庫對應,本地倉庫沒有的依賴jar包,可以從中央倉庫中下載。
