1.新建一个springboot项目，选择gradle管理

 2.gradle添加以下依赖，gradle版本7.4

 dependencies {
        // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web
        implementation 'org.springframework.boot:spring-boot-starter-web:2.6.6'
        // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter
        implementation 'org.springframework.boot:spring-boot-starter:2.6.3'
        implementation 'org.projectlombok:lombok:1.18.12'
        annotationProcessor 'org.projectlombok:lombok:1.18.12'
        implementation 'com.dameng:DmJdbcDriver18:8.1.1.193'
        implementation 'com.dameng:DmDialect-for-hibernate5.3:8.1.1.193'
        // https://mvnrepository.com/artifact/org.hibernate/hibernate-core
        implementation 'org.hibernate:hibernate-core:5.4.21.Final'
        // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-jpa
        implementation 'org.springframework.boot:spring-boot-starter-data-jpa:2.7.5'
        // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-test
        testImplementation 'org.springframework.boot:spring-boot-starter-test:2.6.3'
        // https://mvnrepository.com/artifact/junit/junit
        testImplementation 'junit:junit:4.12'
    }

 3.application.yml配置文件

server:
  port: 8085
spring:
  datasource:
    driver-class-name: dm.jdbc.driver.DmDriver
    url: jdbc:dm://localhost:5236/FDW?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8
    username: FDW
    password: FDW
  jpa:
    properties:
      hibernate:
        dialect: org.hibernate.dialect.DmDialect
    show-sql: true
    hibernate:
      ddl-auto: none

4.达梦数据库新建表空间FDWSPACE，新建用户FDW绑定FDWSPACE

5.在FDW模式下新建一张表test 

CREATE TABLE "FDW"."test"
(
"ID" INTEGER,
"stu_name" VARCHAR(50),
"stu_age" INTEGER) ;

6.新建实体类Student

package com.fdw.study.bean;

import lombok.Data;

import javax.persistence.*;

@Entity
@Table(name = "test")
@Data
public class Student {
    @Id
    @Column(name = "ID")
    private Integer ID;

    @Column(name = "stu_name")
    private String name;

    @Column(name = "stu_age")
    private Integer age;

}

7.DAO接口类StuDao  

package com.fdw.study.dao;

import com.fdw.study.bean.Student;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface StuDao  extends JpaRepository<Student,Integer> {
    List<Student> getByNameAndAge(String name, int age);
    List<Student> getByName(String name);
    @Query(value = "select * from test where stu_age > 1 and stu_name like %:keyword%", nativeQuery = true)
    List<Student> findUserListByAgeAndNameLike(@Param("keyword") String keyword);
}

8.Service接口类StudentService 

package com.fdw.study.service;

import com.fdw.study.bean.Student;


public interface StudentService {

    void saveStudent(Student student);

    void queryAll();

    void getByNameAndAge(String name, int age);

    void getByName(String name);

    void findUserListByAgeAndNameLike(String keyword);

}

9.Service接口实现类StudentServiceImpl 

package com.fdw.study.service;

import com.fdw.study.bean.Student;
import com.fdw.study.dao.StuDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class StudentServiceImpl implements StudentService{
    @Autowired
    StuDao stuDao;


    @Override
    public void saveStudent(Student student) {
        Student save = stuDao.save(student);
        System.out.println("新增或更新一条数据");
        System.out.println(save);
    }

    @Override
    public void queryAll() {
        List<Student> all = stuDao.findAll();
        for (Student s : all) {
            System.out.println(s);
        }
    }

    @Override
    public void getByNameAndAge(String name, int age) {
        List<Student> byNameAndAge = stuDao.getByNameAndAge(name, age);
        for (Student s : byNameAndAge) {
            System.out.println(s);
        }
    }

    @Override
    public void getByName(String name) {
        List<Student> byName = stuDao.getByName(name);
        for (Student s : byName) {
            System.out.println(s);
        }
    }

    public void findUserListByAgeAndNameLike(String keyword){
        List<Student> byName = stuDao.findUserListByAgeAndNameLike(keyword);
        for (Student s : byName) {
            System.out.println(s);
        }
    }
}

10.单元测试

package com.fdw;

import com.fdw.study.bean.Student;
import com.fdw.study.dao.StuDao;
import com.fdw.study.service.StudentServiceImpl;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest(classes = MyApplication.class)
@RunWith(SpringRunner.class)
@ComponentScan("com.fdw.study")
class StudyApplicationTests {
    @Autowired
    StudentServiceImpl studentService;

    @Test
    void contextLoads() {
        Student student = new Student();
        student.setID(3);
        student.setAge(10);
        student.setName("aaa");
        studentService.saveStudent(student);
    }


    @Test
    void contextLoads1() {
        studentService.queryAll();
    }

    @Test
    void contextLoads2() {
        studentService.getByNameAndAge("bbb", 10);
    }

    @Test
    void contextLoads3() {
        studentService.getByName("bbb");
    }

    @Test
    void contextLoads4() {
        studentService.findUserListByAgeAndNameLike("b");
    }
}
