Question

我正在使用Spring Boot中的存储库，但出现错误

原因：java.lang.IllegalArgumentException：不是托管类型：类

我已经用@Entity正确注释了我的实体类。令人惊讶的部分是，如果我将@Repository更改为@NoRepositoryBean，该错误就会消失。有人可以告诉我这里可能出什么问题吗？

错误日志：

实体和存储库：

import lombok.Data;

import javax.persistence.*;
import java.util.Date;

@Data
@Entity
@Table(name = "tenant_info", schema = "fraudefence")
public class TenantInfo {

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "updated_on", insertable = false, updatable = false)
    private Date updatedOn;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "created_timestamp", insertable = false, updatable = false)
    private Date createdTimestamp;

    @Id
    @Column(name = "tenant_id", insertable = false, updatable = false)
    private Integer tenantId;

    @Column(name = "tenant_name", insertable = false, updatable = false)
    private String tenantName;

    @Column(name = "tenant_desc", insertable = false, updatable = false)
    private Integer tenantDesc;

    @Column(name = "tenant_subdomain", insertable = false, updatable = false)
    private String tenantSubdomain;

    @Column(name = "tenant_type_id", insertable = false, updatable = false)
    private Integer tenantTypeId;

    @Column(name = "tenant_key", insertable = false, updatable = false)
    private String tenantKey;

    TenantInfo(){

    }

}

回购：

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface TenantRepository extends JpaRepository<TenantInfo, Long> {
    TenantInfo findTenantInfoByTenantKey(String tenantKey);
}

Answer 1

在Spring Boot入口点类中使用@EntityScan配置实体的位置。

尝试Spring boot - Not an managed type，这对所有步骤都有更好的解释

@NoRepositoryBean与@Repository的非托管类型错误
