如何让spring data mongodb在每个测试方法之前执行createIndexes？

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.index.Index;
import org.springframework.data.mongodb.core.index.IndexDefinition;
import org.springframework.data.mongodb.core.index.IndexOperations;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "your_collection")
public class YourTestClass {

    @Autowired
    private MongoTemplate mongoTemplate;

    @Before
    public void createIndexes() {
        IndexOperations indexOps = mongoTemplate.indexOps(YourEntity.class);
        IndexDefinition indexDef = new Index().on("your_field", Sort.Direction.ASC);
        indexOps.ensureIndex(indexDef);
    }

    @Test
    public void yourTestMethod() {
        // 测试方法的代码
    }
}
