目前，我正在构建一个Spring应用程序，我想使用JUnit编写一些测试，但是由于某种原因，IntelliJ找不到方法assertThat（）。

package com.mycompany;

import static org.junit.Assert.*;
import static org.hamcrest.MatcherAssert.assertThat;
import com.mycompany.book.Book;
import com.mycompany.book.BookRepository;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.test.annotation.Rollback;

@DataJpaTest
@AutoConfigureTestDatabase (replace = AutoConfigureTestDatabase.Replace.NONE)
@Rollback(value = false)
public class BookRepositoryTests {
    @Autowired private BookRepository repo;

    @Test
    public void testAddNew(){
        Book book = new Book();
        book.setTitle("The Divine Comedy");
        book.setAuthor("Dante Alighieri");
        book.setGenre("Poetry");

        Book savedBook = repo.save(book);

    }
}

我已尝试手动添加依赖项

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.12</version>
  <scope>test</scope>
</dependency>

我还确保使用以下命令导入它：

import static org.junit.Assert.*;
import static org.hamcrest.MatcherAssert.assertThat;
