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

Question

我正在尝试测试 Spring Boot 应用程序。我正在使用一个内存 H2 DB，我想用一些数据进行初始化，并通过在项目表中添加一个元素后比较数据库中的数据数量来实现集成测试，但测试失败并且当我尝试跟踪 data.sql 和 schema.sql 执行两次的执行情况。

测试类

@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());
    }

}

架构文件

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 的DataSource 初始化将自动应用classpath:schema.sql 和classpath:data.sql 文件，而无需在您的测试类上使用@SqlGroup 和@Sql。

您应该从测试类中删除 @SqlGroup 和 @Sql 或禁用 DataSource 初始化。实现后者设置spring.datasource.initialization-mode=never（Spring Boot 2.4 及更早版本）或spring.sql.init.mode=never（Spring Boot 2.5 及更高版本）。
