SpringBoot和Hibernate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"

<target>1.8</target>
</configuration>
</plugin>

</project>
3、配置application.properties
# application.properties
# Server settings (ServerProperties)
server.port=8081
server.address=127.0.0.1
#server.sessionTimeout=30
server.contextPath=/SBootDemo
# Tomcat specifics
#server.tomcat.accessLogEnabled=false
server.tomcat.protocolHeader=x-forwarded-proto
server.tomcat.remoteIpHeader=x-forwarded-for
server.tomcat.basedir=
server.tomcat.backgroundProcessorDelay=30
########################################################
###THYMELEAF (ThymeleafAutoConfiguration)
########################################################
#默认是template目录
spring.thymeleaf.prefix=classpath:/static/
spring.thymeleaf.suffix=.html
#spring.thymeleaf.mode=HTML5
#spring.thymeleaf.encoding=UTF-8
# ;charset=<encoding> is added
#spring.thymeleaf.content-type=text/html
# set to false for hot refresh
#Thymeleaf缓存
spring.thymeleaf.cache=false
########################################################
###datasource
########################################################
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://192.168.18.220:3306/test_group
spring.datasource.username = web
spring.datasource.password = web
#spring.datasource.max-active=20
#spring.datasource.max-idle=8
#spring.datasource.min-idle=8
#spring.datasource.initial-size=10
########################################################
### Java Persistence Api
########################################################
# Specify the DBMS
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create：启动会删除表重建, create-drop, update：第一次新建表后面更新，none, validate)
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
#[org.hibernate.cfg.ImprovedNamingStrategy #org.hibernate.cfg.DefaultNamingStrategy]
#spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# stripped before adding them to the entity manager)
#spring.jpa.properties.hibernate.dialect= org.hibernate.dialect.MySQL5Dialect
3、model层
package com.spring.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToMany;
import javax.persistence.Table;
@Entity //加入这个注解，Demo就会进行持久化了
@Table(name="t_api_request_info")
public class ApiName {
@Id
@GeneratedValue //主键，自动递 增
private Integer id;
@Column(name="apiName")
private String apiName; //接口名称
@Column(name="apiHost")
private String apiHost; //接口地址
@Column(name="requestUrl")
private String requestUrl; //接口请求地址
@Column(name="requestMethod")
private String requestMethod; //接口请求方法
省略get set。。。。。。
4、dao持久层
package com.spring.dao;
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import com.spring.model.ApiName;
public interface ApiJpaDao extends JpaRepository<ApiName, Integer> {
// 单条件查询 会生成where ApiHost=?
List<ApiName> findByApiHost(String ApiHost);
//and组合查询 会生成 where ApiName=? And ApiHost=?
List<ApiName> findByApiNameAndApiHost(String ApiName, String ApiHost);
}
5、service层接口类
package com.spring.service;
import java.util.List;
import java.util.Optional;
import org.springframework.data.jpa.repository.JpaRepository;
import com.spring.model.ApiName;
public interface ApiService{
//保存
public ApiName save(ApiName apiName);
//更新
public ApiName update(ApiName apiName);
//删除
public void delete(Integer id);
//查询返回所有列表
public List<ApiName> findAll();
//查询一条记录
public Optional<ApiName> findOne(Integer id);
//通过host查询
public List<ApiName> findByApiHost(String ApiHost);
//通过name 、host查询
public List<ApiName> findByApiNameAndApiHost(String ApiName, String ApiHost);
}
6、service 层实现类
package com.spring.service;
import java.util.List;
import java.util.Optional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.spring.dao.ApiJpaDao;
import com.spring.model.ApiName;
@Service //要加这个注解 表示 为service层，才会自动扫描关生成beans
public class ApiServiceImpl implements ApiService {
@Autowired //加这个注解会自动new
private ApiJpaDao apiJpaDao;
public ApiName save(ApiName apiName) {
return apiJpaDao.save(apiName);
}
public ApiName update(ApiName apiName) {
return apiJpaDao.save(apiName);
}
public void delete(Integer id){
apiJpaDao.deleteById(id);
}
public List<ApiName> findAll() {
return apiJpaDao.findAll();
}
public Optional<ApiName> findOne(Integer id) {
return apiJpaDao.findById(id);
}
public List<ApiName> findByApiHost(String ApiHost){
return apiJpaDao.findByApiHost(ApiHost);
}
public List<ApiName> findByApiNameAndApiHost(String ApiName, String ApiHost) {
return apiJpaDao.findByApiNameAndApiHost(ApiName, ApiHost);
}
}
7、cotroller控制层
package com.spring.controller;
import java.util.HashMap;
import java.util.List;
import java.util.Optional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.spring.model.ApiCase;
import com.spring.model.ApiName;
import com.spring.service.ApiCaseService;
import com.spring.service.ApiService;
@RestController
@SpringBootApplication
@RequestMapping("/api")
public class ApiController {
@Autowired
private ApiService apiService;
/**
*保存测试数据
*/
@GetMapping("/saveget")
public ApiName saveget() {
ApiName apiName = new ApiName();
//apiName.setId(1);
apiName.setApiName("GET接口测试");
apiName.setApiHost("http://www.baidu.com");
apiName.setRequestUrl("/test");
apiName.setRequestMethod("get");
return apiService.save(apiName);
//return "GET保存成功";
}
@PostMapping("/savepost")
public String savepost() {
ApiName apiName = new ApiName();
//apiName.setId(1);
apiName.setApiName("POST接口测试");
apiName.setApiHost("http://www.baidu.com");
apiName.setRequestUrl("/test");
apiName.setRequestMethod("get");
apiService.save(apiName);
return "POST保存成功";
}
//可以不单个字段写传参，直接传model对象ApiName
@RequestMapping(value = "/save") //简单类型的绑定，可以出来get和post http://localhost:8080/index/get?name=wujing http://localhost:8080/index/get?name=无境
public ApiName save(ApiName apiName) {
return apiService.save(apiName);
}
//按id更新 @PutMapping根据主键存在就更新，不存在就插入 可以用put 或 post请求 http://localhost:8081/api/apinaem/1
@PutMapping(value = "/update/{id}")
public ApiName findon(@PathVariable("id") Integer id,
@RequestParam("ApiName") String ApiName,
@RequestParam("ApiHost") String ApiHost,
@RequestParam("RequestUrl") String RequestUrl,
@RequestParam("RequestMethod") String RequestMethod) {
ApiName apiName = new ApiName();
apiName.setId(id);
apiName.setApiName(ApiName);
apiName.setApiHost(ApiHost);
apiName.setRequestUrl(RequestUrl);
apiName.setRequestMethod(RequestMethod);
return apiService.update(apiName);
}
//按id删除
@DeleteMapping(value = "/delete/{id}")
public String deleter(@PathVariable("id") Integer id){
apiService.delete(id);
return "删除成功id:"+id;
}
//获取所有列表
@RequestMapping("/findAll")
public List<ApiName> findAll() {
return apiService.findAll();
}
//按id查询 http://localhost:8081/api/find?id=1
@RequestMapping(value = "/find/id-{id}")
public Optional<ApiName> findon(@PathVariable Integer id) {
return apiService.findOne(id);
}
//通过host查询
@RequestMapping(value = "/find/ApiHost-{ApiHost}")
public List<ApiName> findByApiHost(@PathVariable String ApiHost){
return apiService.findByApiHost(ApiHost);
}
//组合查询
@RequestMapping(value = "/find")
public List<ApiName> findByApiNameAndApiHost(@RequestParam String ApiName,
@RequestParam String ApiHost){
return apiService.findByApiNameAndApiHost(ApiName, ApiHost);
}
}
8、Application启动类
package com.spring.controller;
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;
/**Description: spring boot 启动入口 有三种启动方式
*
* @author luwenhuang
* @date 2017年9月14日 下午2:58:54
*/
@ComponentScan(basePackages={"com.spring"}) // 扫描该包路径下的所有spring组件
@EnableJpaRepositories("com.spring.dao") // JPA扫描该包路径下的Repositorie
@EntityScan("com.spring.model") // 扫描实体类
@SpringBootApplication
public class SpringBootDemoApplication {
/**Description:
* @param args
* void
* @author luwenhuang
* @date 2017年9月18日 下午5:31:49
*/
public static void main(String[] args) {
SpringApplication.run(SpringBootDemoApplication.class, args);
}
}
Run as --- java Application就可以启动项目
