java.lang.IllegalArgumentException: Not a managed type With @Entity and @Repository Setup with Spring Boot 2

Question

我已经查看了该主题的所有其他 stackoverflow，但都没有答案。 我的实体上出现“非托管类型”。 这是课程。

实体：

package com.somecompany.brokerage.party.onborading.api.outbound.db2.models;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import javax.jdo.annotations.Unique;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
@Entity
@Table(name = "CUST", schema = "SAMS")
public class CustDto implements Serializable {

    private static final long serialVersionUID = -3304734256617027874L;

    @Id
    @Unique(name = "IXCUS1")
    @Column(name = "CUST_ID")
    private Integer customerId;

    @Column(name = "CUST_CAN_CALL_IN")
    private String customerCanCallIn;

    @Column(name = "CUST_ADD_DT")
    private Integer customerAddDate;

    @Unique(name = "IXCUS2")
    @Column(name = "TXPYR_ID")
    private String taxPayerId;


}

回购：

package com.somecompany.brokerage.party.onborading.api.outbound.db2.connector;

import com.somecompany.brokerage.party.onborading.api.outbound.db2.models.CustDto;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface DB2CustConnector extends JpaRepository<CustDto, Integer> {

    @Query("select CUST_ID from SAMS.CUST where TXPYR_ID = ':taxPayerId'")
    List<CustDto> retrieveCustomerIdByTaxPayerId(@Param("taxPayerId") String taxPayerId);

}

应用：

package com.somecompany.brokerage.party.onborading;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication(scanBasePackages = {
        "com.somecompany.brokerage.party.onborading.*",
        "com.somecompany.brokerage.party.onborading.exception",
        "com.somecompany.brokerage.party.onborading.service",
        "com.somecompany.brokerage.party.onborading.api.outbound.db2.*",
        "com.somecompany.brokerage.party.onborading.api.outbound.rest.*",
        "com.somecompany.brokerage.party.onborading.api.inbound.rest.*"
})
@EnableJpaRepositories(basePackages = {
        "com.somecompany.brokerage.party.onborading.api.outbound.db2.connector"
})
@EntityScan(basePackages = {
        "com.somecompany.brokerage.party.onborading.api.outbound.db2.models"
})
public class BrokeragePartyOnboradingApplication {

    public static void main(String[] args) {
        SpringApplication.run(BrokeragePartyOnboradingApplication.class, args);
    }


}

适配器：

package com.somecompany.brokerage.party.onborading.api.outbound.db2.adaptor;

import com.somecompany.brokerage.party.onborading.api.outbound.db2.connector.DB2CustConnector;
import com.somecompany.brokerage.party.onborading.api.outbound.db2.models.CustDto;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
public class DB2Adaptor {

    private final DB2CustConnector db2CustConnector;

    public DB2Adaptor(
            DB2CustConnector db2CustConnector
    ) {
        this.db2CustConnector = db2CustConnector;
    }

    public List<CustDto> retrieveCustomerByTaxPayerId(String TaxPayerId) {
        return db2CustConnector.retrieveCustomerIdByTaxPayerId(TaxPayerId);
    }

}

如果有人需要其他代码，我可以添加任何代码，但我觉得这些是最重要的。

Spring 启动 2.2.5

我一直在搜索和阅读几个小时，但没有找到答案。

已尝试：更改 sql 以反映 CustDto class 信息。 仍然得到错误。

@Repository
public interface DB2CustConnector extends JpaRepository<CustDto, Integer> {

    @Query("select c.customerId from CustDto c where c.taxPayerId = ':taxPayerId'")
    List<CustDto> retrieveCustomerIdByTaxPayerId(@Param("taxPayerId") String taxPayerId);

}

已尝试：删除注释和查询以查看是否存在问题。 仍然得到错误。

public interface DB2CustConnector extends JpaRepository<CustDto, Integer> {

}

注意：在方法 managedType 中调试 org.hibernate.metamodel.internal.MetamodelImpl 时，jpaEntityTypeMap 为空。 自从我已经使用 @Entity 和 @EntityScan 以来，关于如何使它具有价值的任何想法？

Answer 1

问题在于@SpringBootApplication ，尝试删除 package 名称中的*并尝试编写完整的打包结构。

@SpringBootApplication(scanBasePackages = {
   "com.schwab.brokerage.party.onborading.api.outbound.db2.models"
})

另请注意， @EntityScan不会创建 bean。 只有@SpringBootApplication会创建bean， @EntityScan只标识特定持久性上下文应该使用哪些类。

Try not to scan every package, as everything within the base package having main class, scan everything within the package, having @Component or any stereotype annotation.

Answer 2

查询看起来像 SQL 查询，您需要将其更改为 JPQL 查询语法。

select c.customerId from CustDto c where c.taxPayerId = :taxPayerId

Answer 3

因此，无论出于何种原因，将应用程序剥离到以下内容修复了我的错误。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EnableJpaRepositories
public class BrokeragePartyOnboradingApplication {

    public static void main(String[] args) {
        SpringApplication.run(BrokeragePartyOnboradingApplication.class, args);
    }

}
