奇怪的行为[Spring Boot Upgrade 2.2.2]正在获取java.lang.NullPointerException：org.hibernate.loader.custom.sql.NamedParamBinder.bind

将Spring Boot从 1.5.x 升级到 2.2.2 后，出现上述错误。我相信这也已经升级了Hibernate版本，这可能会导致上述错误。我不确定这是否是Hibernate中的错误

是否应该通过在gradle中指定降级我的Hibernate版本？而不是使用 Spring Boot 2.2.2 提供的默认值？

Hibernate 5.x是否有缺陷？

程序成功启动。当程序尝试执行本机查询时，它将给出错误；语法如下所示

    @Query(value = " SELECT ds.* FROM DocumentSimilarity AS ds INNER JOIN CompanyDocumentInfo AS hi ON hi.companyDocumentInfoID = ds.companyDocumentInfoID AND hi.isDeleted=:isDeleted AND hi.siteID=:siteID AND hi.clientID=:clientID  " +
            "WHERE        (ds.processstatus =:documentProcessstatus) AND (hi.processstatus =:similarityProcessstatus) AND (hi.excelProcessstatus in:eXcelProcessstatus) order by ds.modifiedDate /*#pageable*/",countQuery = "select count(modifiedDate) from DocumentSimilarity order by modifiedDate /*#pageable*/ ",nativeQuery = true)
    List<DocumentSimilarity> getSimilarityRecordForExcel(@Param("clientID") int clientID,@Param("siteID") String siteID,@Param("documentProcessstatus") String documentProcessstatus,@Param("isDeleted") int isDeleted,@Param("eXcelProcessstatus") List<String> excelProcessstatus,@Param("similarityProcessstatus") String similarityProcessstatus,Pageable pageable);

发现

当它尝试在下面执行时

final TypedValue typedValue = qp.getNamedParameters().get( name );
typedValue.getType().nullSafeSet( statement,typedValue.getValue(),position,session );

typedValue为空，名称=“ eXcelProcessstatus”

我已经正确拼写了 eXcelProcessstatus ，因为它在数据库表和我的Entity类中

下面是

中的值

qp.getNamedParameters()

{documentProcessstatus=PROCESSED,clientID=1,isDeleted=0,similarityProcessstatus=nopROCESS,siteID=3}

它不包含 eXcelProcessstatus ，我不确定这是否与 eXcelProcessstatus

更多发现。

我也曾尝试降低@param(name=excelProcessstatus)中的X，但仍然出现相同的错误。

休眠版本：
hibernate-core-5.4.20.Final.jar
hibernate-validator-6.1.5.Final.jar
hibernate-commons-annotations-5.1.0.Final.jar
hibernate-c3p0-5.4.21.Final.jar

解决方法

不确定这是否是由于升级引起的，但是在查询中进行了以下更改（这是一个巨大的更改）[空格]

代替

(hi.excelProcessStatus in:eXcelProcessStatus)

这样做 (hi.excelProcessStatus in: eXcelProcessStatus)

已经解决了问题。问题似乎只存在于 [空格] 。

这样的书写方法

@Query(value = " SELECT ds.* FROM DocumentSimilarity AS ds INNER JOIN CompanyDocumentInfo AS hi ON hi.companyDocumentInfoID = ds.companyDocumentInfoID AND hi.isDeleted=:isDeleted AND hi.siteID=:siteID AND hi.clientID=:clientID  " +
            "WHERE        (ds.processStatus =:documentProcessStatus) AND (hi.processStatus =:similarityProcessStatus) AND (hi.excelProcessStatus in: eXcelProcessStatus) order by ds.modifiedDate /*#pageable*/",countQuery = "select count(modifiedDate) from DocumentSimilarity order by modifiedDate /*#pageable*/ ",nativeQuery = true)
    List<DocumentSimilarity> getSimilarityRecordForExcel(@Param("clientID") int clientID,@Param("siteID") String siteID,@Param("documentProcessStatus") String documentProcessStatus,@Param("isDeleted") int isDeleted,@Param("eXcelProcessStatus") List<String> excelProcessStatus,@Param("similarityProcessStatus") String similarityProcessStatus,Pageable pageable);
