SpringBoot+Hibernate整合

SpringBoot和Hibernate簡(jiǎn)單的整合步驟 。使用Eclipse工具
1、新建一個(gè)maven項(xiàng)目

2、pom.xm設(shè)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/maven-v4_0_0.xsd">

</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)  
########################################################  
#默認(rèn)是template目錄
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緩存
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：?jiǎn)?dòng)會(huì)刪除表重建, 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層

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 //加入這個(gè)注解，Demo就會(huì)進(jìn)行持久化了
@Table(name="t_api_request_info")
public class ApiName {
    
    @Id
    @GeneratedValue //主鍵，自動(dòng)遞 增
    private Integer id;
    @Column(name="apiName")
    private String apiName; //接口名稱
    @Column(name="apiHost")
    private String apiHost; //接口地址
    @Column(name="requestUrl")
    private String requestUrl; //接口請(qǐng)求地址
    @Column(name="requestMethod")
    private String requestMethod; //接口請(qǐng)求方法
省略get set。。。。。。

4、dao持久層

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> {
    // 單條件查詢   會(huì)生成where ApiHost=?
    List<ApiName> findByApiHost(String ApiHost);
    //and組合查詢  會(huì)生成 where ApiName=? And ApiHost=?
    List<ApiName> findByApiNameAndApiHost(String ApiName, String ApiHost);
}

5、service層接口類

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);
    //刪除
    public void delete(Integer id);
    //查詢返回所有列表
    public List<ApiName> findAll();
    //查詢一條記錄
    public Optional<ApiName> findOne(Integer id);
    //通過(guò)host查詢
    public List<ApiName> findByApiHost(String ApiHost);
    //通過(guò)name 、host查詢
    public List<ApiName> findByApiNameAndApiHost(String ApiName, String ApiHost);
}

6、service 層實(shí)現(xiàn)類

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  //要加這個(gè)注解 表示 為service層，才會(huì)自動(dòng)掃描關(guān)生成beans
public class ApiServiceImpl implements ApiService {
    
    @Autowired  //加這個(gè)注解會(huì)自動(dòng)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控制層

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;

    /**
     *保存測(cè)試數(shù)據(jù) 
     */
    @GetMapping("/saveget")
    public ApiName saveget() {
        ApiName apiName = new ApiName();
        //apiName.setId(1);
        apiName.setApiName("GET接口測(cè)試");
        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接口測(cè)試");
        apiName.setApiHost("http://www.baidu.com");
        apiName.setRequestUrl("/test");
        apiName.setRequestMethod("get");
        apiService.save(apiName);
        return "POST保存成功";
    }

    //可以不單個(gè)字段寫傳參，直接傳model對(duì)象ApiName
    @RequestMapping(value = "/save") //簡(jiǎn)單類型的綁定，可以出來(lái)get和post  http://localhost:8080/index/get?name=wujing    http://localhost:8080/index/get?name=無(wú)境
    public ApiName save(ApiName apiName) {
        return apiService.save(apiName);
    }
    
    //按id更新 @PutMapping根據(jù)主鍵存在就更新，不存在就插入 可以用put 或 post請(qǐng)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刪除
    @DeleteMapping(value = "/delete/{id}")
    public String deleter(@PathVariable("id") Integer id){
        apiService.delete(id);
        return "刪除成功id:"+id;
    }
    
    //獲取所有列表
    @RequestMapping("/findAll")
    public List<ApiName> findAll() {
        return apiService.findAll();
    }
    
    //按id查詢  http://localhost:8081/api/find?id=1
    @RequestMapping(value = "/find/id-{id}")
    public Optional<ApiName> findon(@PathVariable Integer id) {
        return apiService.findOne(id);
    }
    
    //通過(guò)host查詢
    @RequestMapping(value = "/find/ApiHost-{ApiHost}")
    public List<ApiName> findByApiHost(@PathVariable String ApiHost){
        return apiService.findByApiHost(ApiHost);
    }
    
    //組合查詢
    @RequestMapping(value = "/find")
    public List<ApiName> findByApiNameAndApiHost(@RequestParam String ApiName,
                                                @RequestParam String ApiHost){
        return apiService.findByApiNameAndApiHost(ApiName, ApiHost);
    }   
}

8、Application啟動(dòng)類

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 啟動(dòng)入口 有三種啟動(dòng)方式
 * 
 * @author luwenhuang
 * @date 2017年9月14日 下午2:58:54
 */
@ComponentScan(basePackages={"com.spring"}) // 掃描該包路徑下的所有spring組件
@EnableJpaRepositories("com.spring.dao") // JPA掃描該包路徑下的Repositorie
@EntityScan("com.spring.model") // 掃描實(shí)體類
@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就可以啟動(dòng)項(xiàng)目
