spring boot 正在执行 data.sql 和 schema.sql 两次？

Question

I was trying to test a Spring Boot Application. I am using an in-memory H2 DB that I would like to initialize with some data and implement an integration test by comparing the number of data in the database after I have added one element in the project table but the test is failing and when I try to track the execution the data.sql and schema.sql are executed two times.

test class

@ContextConfiguration(classes=ProjectManagementApplication.class)
@RunWith(SpringRunner.class)
@DataJpaTest
@SqlGroup(@Sql( executionPhase = ExecutionPhase.BEFORE_TEST_METHOD, scripts= {"classpath:schema.sql","classpath:data.sql"}))
public class ProjectRepositoryIntegrationTest {
    @Autowired
    ProjectRepository proRepo;
    @Autowired
    EmployeeRepository empRepo;
    @Test
    public void ifNewProjectSaved_thenSuccess() {
        Project newProject=new Project("new Project","COMPLETED","test Description");
        proRepo.save(newProject);
        List<Project> pro= proRepo.findAll();
        for(int i=0;i<pro.size();i++) {
            System.out.println(pro.get(i));
        }
        assertEquals(5,pro.size());
    }

}

schema file

CREATE SEQUENCE IF NOT EXISTS employee_seq;

CREATE TABLE IF NOT EXISTS employee (

employee_id BIGINT NOT NULL DEFAULT nextval('employee_seq') PRIMARY KEY,
first_name VARCHAR(100) NOT NULL,
lastname VARCHAR(100) NOT NULL,
email VARCHAR(100) NOT NULL


);

CREATE SEQUENCE IF NOT EXISTS project_seq;

CREATE TABLE IF NOT EXISTS project (

project_id BIGINT NOT NULL DEFAULT nextval('project_seq') PRIMARY KEY,
name VARCHAR(100) NOT NULL,
stage VARCHAR(100) NOT NULL,
description VARCHAR(500) NOT NULL

);


CREATE TABLE IF NOT EXISTS employee_project (

project_id BIGINT REFERENCES project, 
employee_id BIGINT REFERENCES employee

Answer 1

Spring Boot's DataSource initialization will apply classpath:schema.sql and classpath:data.sql files automatically without using @SqlGroup and @Sql on your test class.

You should either remove @SqlGroup and @Sql from your test class or disable DataSource initialization. To achieve the latter set spring.datasource.initialization-mode=never (Spring Boot 2.4 and earlier) or spring.sql.init.mode=never (Spring Boot 2.5 and later).
