SpringBoot+SpringMvc+Hibernate整合
SpringBoot+SpringMvc+Hibernate+Swagger简单的整合步骤 。使用Eclipse工具1、新建一个maven项目
2、pom.xm设置
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</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.html3、Repository接口层
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、实体类Entity层
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控制层
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 = "用户信息")
@EnableAutoConfiguration
public class UserController {
@Autowired
private UserRepository userRepository;
@GetMapping(value = "/getUserById")
@ApiOperation(value = "通过用户ID查找用户信息")
public User getUserById(@RequestParam(name = "id") Integer id){
List<User> users = userRepository.findAll();
return userRepository.getUserById(id);
}
}
6、Application启动类
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"}) // 扫描该包路径下的所有spring组件
@EnableJpaRepositories("com.springboot.service.repository") // JPA扫描该包路径下的Repositorie
@EntityScan("com.springboot.service.entity") // 扫描实体类
@EnableSwagger2 // Swagger
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}7、配置Swagger 的一个Swagger配置类，放在启动类扫描的包下，建议和启动类放在同一目录下；
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构建api文档")
.description("简单优雅的restfun风格")
.termsOfServiceUrl("http://blog.csdn.net/saytime")
.version("2.0")
.build();
}
}Run as --- java Application就可以启动项目
注意：
maven除了本地化之外，还需在 .../conf/setting.xml文件中，增加以下配置，主要和工程中配置中央仓库对应，本地仓库没有的依赖jar包，可以从中央仓库中下载。
